您需要做的就是在您的主题中设置这些属性:
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
您希望拥有透明状态栏的活动/容器布局需要此属性集:
android:fitsSystemWindows="true"
通常不可能在 pre-kitkat 上确定执行此操作,看起来您可以执行此操作but some strange code makes it so。
编辑:我会推荐这个 lib: https://github.com/jgilfelt/SystemBarTint 用于大量的棒棒糖前状态栏颜色控制。
经过深思熟虑后,我了解到完全禁用棒棒糖状态栏和导航栏上的半透明或任何颜色的答案是在窗口上设置此标志:
// In Activity's onCreate() for instance
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window w = getWindow();
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}
不需要其他主题,它会产生如下内容:

您可以使用下面的代码使状态栏透明。查看带有红色突出显示的图像,可帮助您识别以下代码的使用
https://i.stack.imgur.com/wOgJi.png
您的 Android 应用程序的 Kotlin 代码片段
Step:1 在 On create Method 中写下代码
if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true)
}
if (Build.VERSION.SDK_INT >= 19) {
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
}
if (Build.VERSION.SDK_INT >= 21) {
setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false)
window.statusBarColor = Color.TRANSPARENT
}
Step2:您需要下面代码中描述的 SetWindowFlag 方法。
private fun setWindowFlag(bits: Int, on: Boolean) {
val win = window
val winParams = win.attributes
if (on) {
winParams.flags = winParams.flags or bits
} else {
winParams.flags = winParams.flags and bits.inv()
}
win.attributes = winParams
}
您的 android 应用程序的 Java 代码片段:
Step1:主要活动代码
if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true);
}
if (Build.VERSION.SDK_INT >= 19) {
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}
if (Build.VERSION.SDK_INT >= 21) {
setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false);
getWindow().setStatusBarColor(Color.TRANSPARENT);
}
Step2:SetWindowFlag 方法
public static void setWindowFlag(Activity activity, final int bits, boolean on) {
Window win = activity.getWindow();
WindowManager.LayoutParams winParams = win.getAttributes();
if (on) {
winParams.flags |= bits;
} else {
winParams.flags &= ~bits;
}
win.setAttributes(winParams);
}
只需将这行代码添加到您的主 java 文件中:
getWindow().setFlags(
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
);
适用于 Android KitKat 及更高版本(对于那些想要透明状态栏且不操纵 NavigationBar 的人,因为所有这些答案也会使 NavigationBar 透明!)
实现它的最简单方法:
将这 3 行代码放在 styles.xml (v19)
->如果您不知道如何获得它(v19),只需将它们写入您的默认 styles.xml
,然后使用 alt+enter 自动创建它:
<item name="android:windowFullscreen">false</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:fitsSystemWindows">false</item>
现在,转到您的 MainActivity
类并将此方法从类中的 onCreate 中删除:
public static void setWindowFlag(Activity activity, final int bits, boolean on) {
Window win = activity.getWindow();
WindowManager.LayoutParams winParams = win.getAttributes();
if (on) {
winParams.flags |= bits;
} else {
winParams.flags &= ~bits;
}
win.setAttributes(winParams);
}
然后将此代码放入 Activity 的 onCreate
方法中:
if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true);
}
if (Build.VERSION.SDK_INT >= 19) {
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}
//make fully Android Transparent Status bar
if (Build.VERSION.SDK_INT >= 21) {
setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false);
getWindow().setStatusBarColor(Color.TRANSPARENT);
}
而已!
完全透明的状态栏和导航栏
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
transparentStatusAndNavigation();
}
private void transparentStatusAndNavigation() {
//make full transparent statusBar
if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
| WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, true);
}
if (Build.VERSION.SDK_INT >= 19) {
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
);
}
if (Build.VERSION.SDK_INT >= 21) {
setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
| WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, false);
getWindow().setStatusBarColor(Color.TRANSPARENT);
getWindow().setNavigationBarColor(Color.TRANSPARENT);
}
}
private void setWindowFlag(final int bits, boolean on) {
Window win = getWindow();
WindowManager.LayoutParams winParams = win.getAttributes();
if (on) {
winParams.flags |= bits;
} else {
winParams.flags &= ~bits;
}
win.setAttributes(winParams);
}
在状态栏下绘制布局:
值/样式.xml
<item name="android:windowTranslucentStatus">true</item>
值-v21/styles.xml
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@color/colorPrimaryDark</item>
使用 CoordinatorLayout/DrawerLayout 已经处理了 fitSystemWindows 参数或创建自己的布局,如下所示:
public class FitsSystemWindowConstraintLayout extends ConstraintLayout {
private Drawable mStatusBarBackground;
private boolean mDrawStatusBarBackground;
private WindowInsetsCompat mLastInsets;
private Map<View, int[]> childsMargins = new HashMap<>();
public FitsSystemWindowConstraintLayout(Context context) {
this(context, null);
}
public FitsSystemWindowConstraintLayout(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public FitsSystemWindowConstraintLayout(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
if (ViewCompat.getFitsSystemWindows(this)) {
ViewCompat.setOnApplyWindowInsetsListener(this, new android.support.v4.view.OnApplyWindowInsetsListener() {
@Override
public WindowInsetsCompat onApplyWindowInsets(View view, WindowInsetsCompat insets) {
FitsSystemWindowConstraintLayout layout = (FitsSystemWindowConstraintLayout) view;
layout.setChildInsets(insets, insets.getSystemWindowInsetTop() > 0);
return insets.consumeSystemWindowInsets();
}
});
setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
TypedArray typedArray = context.obtainStyledAttributes(new int[]{android.R.attr.colorPrimaryDark});
try {
mStatusBarBackground = typedArray.getDrawable(0);
} finally {
typedArray.recycle();
}
} else {
mStatusBarBackground = null;
}
}
public void setChildInsets(WindowInsetsCompat insets, boolean draw) {
mLastInsets = insets;
mDrawStatusBarBackground = draw;
setWillNotDraw(!draw && getBackground() == null);
for (int i = 0; i < getChildCount(); i++) {
View child = getChildAt(i);
if (child.getVisibility() != GONE) {
if (ViewCompat.getFitsSystemWindows(this)) {
ConstraintLayout.LayoutParams layoutParams = (ConstraintLayout.LayoutParams) child.getLayoutParams();
if (ViewCompat.getFitsSystemWindows(child)) {
ViewCompat.dispatchApplyWindowInsets(child, insets);
} else {
int[] childMargins = childsMargins.get(child);
if (childMargins == null) {
childMargins = new int[]{layoutParams.leftMargin, layoutParams.topMargin, layoutParams.rightMargin, layoutParams.bottomMargin};
childsMargins.put(child, childMargins);
}
if (layoutParams.leftToLeft == LayoutParams.PARENT_ID) {
layoutParams.leftMargin = childMargins[0] + insets.getSystemWindowInsetLeft();
}
if (layoutParams.topToTop == LayoutParams.PARENT_ID) {
layoutParams.topMargin = childMargins[1] + insets.getSystemWindowInsetTop();
}
if (layoutParams.rightToRight == LayoutParams.PARENT_ID) {
layoutParams.rightMargin = childMargins[2] + insets.getSystemWindowInsetRight();
}
if (layoutParams.bottomToBottom == LayoutParams.PARENT_ID) {
layoutParams.bottomMargin = childMargins[3] + insets.getSystemWindowInsetBottom();
}
}
}
}
}

public void setStatusBarBackground(Drawable bg) {
mStatusBarBackground = bg;

mStatusBarBackground = resId != 0 ? ContextCompat.getDrawable(getContext(), resId) : null;
invalidate();
}
public void setStatusBarBackgroundColor(@ColorInt int color) {
mStatusBarBackground = new ColorDrawable(color);
invalidate();
}
@Override
public void onDraw(Canvas canvas) {
super.onDraw(canvas);
if (mDrawStatusBarBackground && mStatusBarBackground != null) {
int inset = mLastInsets != null ? mLastInsets.getSystemWindowInsetTop() : 0;
if (inset > 0) {
mStatusBarBackground.setBounds(0, 0, getWidth(), inset);
mStatusBarBackground.draw(canvas);
}
}
}
}

结果:
https://i.stack.imgur.com/DlHNA.png
简单明了,适用于几乎所有用例(API 级别 16 及以上):
在您的应用主题中使用以下标记使状态栏透明:
这就是你需要做的一切;)
您可以从developer documentation.我也推荐阅读this博文了解更多信息。
科特林代码:
val decorView = window.decorView
decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)
检查我的另一个答案here
这是 kotlin 中的一个扩展,可以解决问题:
fun Activity.setTransparentStatusBar() {
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.statusBarColor = Color.TRANSPARENT
}
}
在顶部布局中使用 android:fitsSystemWindows="false"
有三个步骤:
1)只需将此代码段用于您的 OnCreate 方法
// FullScreen
getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
如果您正在处理 Fragment,则应将此代码段放在活动的 OnCreate 方法中。
2) 一定要在 /res/values-v21/styles.xml 中设置透明度:
<item name="android:statusBarColor">@android:color/transparent</item>
或者您可以以编程方式设置透明度:
getWindow().setStatusBarColor(Color.TRANSPARENT);
3)无论如何你应该在styles.xml中添加代码段
<item name="android:windowTranslucentStatus">true</item>
注意:此方法仅适用于 API 21 及更高版本。
对于 API > 23 日/夜支持,您可以使用下面的扩展。要理解的重要部分是 android:fitsSystemWindows="true"
使用填充在插入内移动(就像使用工具栏一样)。因此,将其放置在您的根布局中是没有意义的(除了 DrawerLayout、CoordinatorLayout,......这些使用它们自己的实现)。
https://i.stack.imgur.com/iPULG.png
<style name="Theme.YourApp.DayNight" parent="Theme.MaterialComponents.DayNight.NoActionBar">

window.decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)
} else {
window.setDecorFitsSystemWindows(false)
}
}
然后像这样调用它:
class YourActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
...
transparentStatusBar()
}
}
查看 Chris Banes 的这些幻灯片:Becoming a master window fitter
编辑:如果您在导航栏后面浮动的内容有问题,请使用
// using Insetter
binding.yourViewHere.applySystemWindowInsetsToPadding(bottom = true)
我刚刚找到它here
因为已经过了 6 年,默认的 minSDKAPI 是 21 (Lollipop) *CMIIW。这是我总结透明状态栏而不与导航按钮重叠的方法:
fun setStatusBarTransparent(activity: Activity, view: View) {
activity.apply {
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
window.statusBarColor = ContextCompat.getColor(this, R.color.transparent)
WindowCompat.setDecorFitsSystemWindows(window, false)
ViewCompat.setOnApplyWindowInsetsListener(view) { root, windowInset ->
val inset = windowInset.getInsets(WindowInsetsCompat.Type.systemBars())
root.updateLayoutParams<ViewGroup.MarginLayoutParams> {
leftMargin = inset.left
bottomMargin = inset.bottom
rightMargin = inset.right
}
WindowInsetsCompat.CONSUMED
}
}
}
我将该函数放在名为 UiUtils
的 Object
类中,因此当我在我的活动中调用该函数时(我也使用视图绑定)。它看起来像这样:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
...
UiUtils.setStatusBarTransparent(this, bind.root)
...
}
希望我的回答能帮到大家:)
这是我经过大量搜索后找到的一种简单方法。
步骤1
在你的主题中放这个项目
<item name="android:statusBarColor" tools:targetApi="lollipop">@android:color/transparent</item>
第2步
在主要活动中
WindowCompat.setDecorFitsSystemWindows(window, false)
如果您使用 BottomNavigationBar,则非常重要
在某些设备中,如果在您的应用程序中使用 API 30+,您会发现系统导航栏与底部导航栏重叠。
这是解决这个问题。
if (Build.VERSION.SDK_INT >= 30) {
// Root ViewGroup of my activity
val root = findViewById<ConstraintLayout>(R.id.root)
ViewCompat.setOnApplyWindowInsetsListener(root) { view, windowInsets ->
val insets = windowInsets.getInsets(WindowInsetsCompat.Type.systemBars())
// Apply the insets as a margin to the view. Here the system is setting
// only the bottom, left, and right dimensions, but apply whichever insets are
// appropriate to your layout. You can also update the view padding
// if that's more appropriate.
view.layoutParams = (view.layoutParams as FrameLayout.LayoutParams).apply {
leftMargin = insets.left
bottomMargin = insets.bottom
rightMargin = insets.right
}
// Return CONSUMED if you don't want want the window insets to keep being
// passed down to descendant views.
WindowInsetsCompat.CONSUMED
}
}
在您的 XML 中使用此代码,您将能够在您的活动中看到时间栏:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
我发现摆弄 style.xml 和活动太麻烦,因此创建了一个通用实用程序方法,它具有以下选项集
爪哇
Window window = getWindow();
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
window.setStatusBarColor(Color.TRANSPARENT);
科特林 DSL
activity.window.apply {
clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
statusBarColor = Color.TRANSPARENT
}
这就是实现透明状态栏所需的全部内容。希望这可以帮助。
<style name="Theme.Transparent" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
<item name="android:windowBackground">@android:color/transparent</item>
</style>
这对我有用:
<item name="android:statusBarColor">@android:color/transparent</item>
<item name="android:navigationBarColor">@android:color/transparent</item>
<item name="android:windowTranslucentStatus">false</item>
<item name="android:windowTranslucentNavigation">false</item>
试试下面的代码:
private static void setStatusBarTransparent(Activity activity) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
activity.getWindow(). setStatusBarColor(Color.TRANSPARENT);
} else {
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
}
它只是删除了状态栏颜色!
window?.decorView?.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
window?.statusBarColor = Color.TRANSPARENT
https://i.stack.imgur.com/tvxt1.jpg
它对我有用,希望它也对你有用
只需进入MainActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Window g = getWindow();
g.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
setContentView(R.layout.activity_main);
}
在我的情况下,我根本不调用“onCreate”(它是一个反应原生应用程序,这也可以通过使用 react-native StatusBar 组件来修复),也可以使用这个:
override fun onStart() {
super.onStart()
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or View.SYSTEM_UI_FLAG_LAYOUT_STABLE
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
window.statusBarColor = Color.TRANSPARENT
}
虽然上面的所有答案都围绕着相同的基本思想,但您可以使用上面的示例之一让它与简单的布局一起工作。但是,我想在使用滑动“全屏”(标签栏旁边)片段导航时更改背景颜色,并保持常规导航、标签和操作栏。
仔细阅读an article by Anton Hadutski后,我更好地理解了发生了什么。
我有 DrawerLayout
和 ConstraintLayout
(即容器),它有 Toolbar
,包括主要片段和 BottomNavigationView
。
将具有 fitsSystemWindows
的 DrawerLayout
设置为 true 是不够的,您需要同时设置 DrawerLayout
和 ConstraintLayout
。假设状态栏是透明的,现在状态栏颜色与 ConstraintLayout
的背景颜色相同。
但是,包含的片段仍然插入了状态栏,因此在 with 顶部设置另一个“全屏”片段的动画不会改变状态栏的颜色。
Activity
的 onCreate
中引用的文章中的一些代码:
ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.container)) { view, insets ->
insets.replaceSystemWindowInsets(
insets.systemWindowInsetLeft,
0,
insets.systemWindowInsetRight,
insets.systemWindowInsetBottom
)
}
一切都很好,除了现在 Toolbar
没有解决状态栏高度。更多参考文章,我们有一个完整的解决方案:
val toolbar = findViewById<Toolbar>(R.id.my_toolbar)
ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.container)) { view, insets ->
val params = toolbar.layoutParams as ViewGroup.MarginLayoutParams
params.topMargin = insets.systemWindowInsetTop
toolbar.layoutParams = params
insets.replaceSystemWindowInsets(
insets.systemWindowInsetLeft,
0,
insets.systemWindowInsetRight,
insets.systemWindowInsetBottom
)
}
main_activity.xml(请注意Toolbar
中的marginTop是为了预览,会被代码替换):
<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

...>
...
</androidx.appcompat.widget.Toolbar>
<include layout="@layout/content_main" />
...
</androidx.constraintlayout.widget.ConstraintLayout>
...
</androidx.drawerlayout.widget.DrawerLayout>
这是 Kotlin 扩展:
fun Activity.transparentStatusBar() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION)
window.statusBarColor = Color.TRANSPARENT
} else
window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
}
android:fitsSystemWindows="true"
仅适用于 v21。我们可以在主题 xml 或父布局(如 LinearLayout
或 CoordinateLayout
)中设置它。对于 v21 以下,我们无法添加此标志。请根据您的需要使用不同的 style.xml
文件创建不同的值文件夹。
<item name="android:statusBarColor" tools:targetApi="lollipop">@android:color/transparent</item>
<!--<item name="android:windowLightStatusBar" tools:targetApi="m">true</item>-->
不要使用 windowLightStatusBar
而是使用 statusBarColor = @android:color/transparent
就我而言,因为我有一个底部工具栏,所以在测试以前的解决方案时遇到了问题,android 系统按钮被我的底部菜单覆盖,我的解决方案是在活动中添加:
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // 强制全屏模式 requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.main_activity_container);
您可以使用下面的代码。
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
getWindow().setStatusBarColor(Color.TRANSPARENT);
将此布局包含在您的主布局中。
工具栏.xml
<?xml version="1.0" encoding="utf-8"?>

app:contentInsetLeft="0dp"
app:contentInsetRight="0dp"
app:contentInsetStart="0dp">

android:textStyle="bold"

</LinearLayout>
</RelativeLayout>
</androidx.appcompat.widget.Toolbar>
注意:您可以将 SDP 和 SSP 分别替换为 dp 和 sp。
这应该工作
// 例如在 Activity 的 onCreate() 中
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window w = getWindow();
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}
在 setContentView() 之前将这些行添加到您的活动中
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window w = getWindow();
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}
将这两行添加到您的 AppTheme
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
最后一件事你的 minSdkVersion 必须 b 19
minSdkVersion 19
以下代码将使您的状态栏和导航栏透明(请注意,这将使您的布局成为全屏布局,就像游戏中使用的布局一样):
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus) {
hideSystemUI();
}
}
private void hideSystemUI() {
// Enables sticky immersive mode.
// For "lean back" mode, remove SYSTEM_UI_FLAG_IMMERSIVE_STICKY.
// Or for regular immersive mode replace it with SYSTEM_UI_FLAG_IMMERSIVE
View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
// Set the content to appear under the system bars so that the
// content doesn't resize when the system bars hide and show.
| View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
// Hide the nav bar and status bar
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN);
}

添加到了我的 activity_main.xml。系统栏是半透明的而不是透明的。<item name="android:statusBarColor">@android:color/transparent</item>
添加到您的主题:)android:windowTranslucentStatus
设置为 false 并且它使状态栏透明。现在我对导航栏做了同样的事情并添加了<item name="android:navigationBarColor">@android:color/transparent</item>
但它使两个栏都变灰。啊!w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);
