In XML, we can set a text color by the textColor
attribute, like android:textColor="#FF0000"
. But how do I change it by coding?
I tried something like:
holder.text.setTextColor(R.color.Red);
Where holder
is just a class and text
is of type TextView
. Red is an RGB value (#FF0000) set in strings.
But it shows a different color rather than red. What kind of parameter can we pass in setTextColor()? In documentation, it says int
, but is it a resource reference value or anything else?
You should use:
holder.text.setTextColor(Color.RED);
You can use various functions from the Color
class to get the same effect of course.
Color.parseColor (Manual) (like LEX uses) text.setTextColor(Color.parseColor("#FFFFFF"));
Color.rgb and Color.argb (Manual rgb) (Manual argb) (like Ganapathy uses) holder.text.setTextColor(Color.rgb(200,0,0)); holder.text.setTextColor(Color.argb(0,200,0,0));
And of course, if you want to define your color in an XML file, you can do this:
You can also insert plain HEX, like so: myTextView.setTextColor(0xAARRGGBB); Where you have an alpha-channel first, then the color value.
Check out the complete manual of course, public class Color extends Object.
1This code used to be in here as well:
textView.setTextColor(getResources().getColor(R.color.errorColor));
This method is now deprecated in Android M. You can however use it from the contextCompat in the support library, as the example now shows.
If you still want to specify your colors in your XML file:
<color name="errorColor">#f00</color>
Then reference it in your code with one of these two methods:
textView.setTextColor(getResources().getColor(R.color.errorColor, getResources().newTheme()));
or
textView.setTextColor(getResources().getColor(R.color.errorColor, null));
The first is probably preferable if you're compiling against Android M, however the theme you pass in can be null, so maybe that's easier for you?
And if you're using the Compat library you can do something like this
textView.setTextColor(ContextCompat.getColor(context, R.color.errorColor));
getColor(int)
is deprecated. ContextCompat.getColor(getContext(), R.color.yourColor);
seems to be the replacement.
And another one:
TextView text = (TextView) findViewById(R.id.text);
text.setTextColor(Color.parseColor("#FFFFFF"));
getResources()
is a Context member function. For adapters, use getContext().getResources()
. Color values should go into resources, like in @xbakesx's answer.
You can do this only from an XML file too.
Create a color.xml
file in the values folder:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="textbody">#ffcc33</color>
</resources>
Then in any XML file, you can set color for text using,
android:textColor="@color/textbody"
Or you can use this color in a Java file:
final TextView tvchange12 = (TextView) findViewById(R.id.textView2);
//Set color for textbody from color.xml file
tvchange1.setTextColor(getResources().getColor(R.color.textbody));
You can use
holder.text.setTextColor(Color.rgb(200,0,0));
You can also specify what color you want with Transparency.
holder.text.setTextColor(Color.argb(0,200,0,0));
a for Alpha (Transparent) value r-red g-green b-blue
use the following code in layout.xml
<TextView android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/add"
android:layout_marginTop="16dp"
android:textAppearance="?
android:attr/textAppearanceMedium"
android:textColor="#25383C"
android:textSize="13sp" />
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/add"
android:layout_marginTop="16dp"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#25383C"
android:textSize="13sp" />
There are many different ways to set color on text view.
Add color value in studio res->values->colors.xml as
textView.setTextColor(ContextCompat.getColor(getApplicationContext(),R.color.colorWhite));
In the colors.xml
file, write in the code below:
<color name="colorWhite">#FFFFFF</color>
I normally do this for any views:
myTextView.setTextColor(0xAARRGGBB);
where
AA defines alpha (00 for transparent, FF for opaque)
RRGGBB defines the normal HTML color code (like FF0000 for red).
If you plan to use setTextAppearance you should know that it will overwrite the text color with the style inherited from the theme. So if you want to use both, set the color afterwards.
This works:
textView.setTextAppearance(context, android.R.style.TextAppearance_Medium);
textView.setTextColor(Color.RED);
While this will cause your textcolor to be for instance white(for dark theme) or black(for the light theme):
textView.setTextColor(Color.RED);
textView.setTextAppearance(context, android.R.style.TextAppearance_Medium);
Contrary to this in XML the order is arbitrary.
I believe that if you want to specify a color as a resource (in the XML file), you'll have to provide its ARGB value (not simply the RGB value).
Try changing your color value to #FFFF0000
. It should give you RED.
text.setTextColor(getResource().getColor(R.color.black))
you have create black color in color.xml.
OR
text.setTextColor(Color.parseColor("#000000"))
here type desired hexcode
OR
text.setTextColor(Color.BLACK)
you can use static color fields
Use:
TextView tv = new TextView(this);
tv.setTextColor(Color.rgb(285,0,0));
holder.text.setTextColor(Color.rgb(200,0,0));
or
myTextView.setTextColor(0xAARRGGBB);
Kotlin Extension Solution
Add these to make changing text color simpler
For setting ColorInt
myView.textColor = Color.BLACK // or Color.parseColor("#000000"), etc.
var TextView.textColor: Int
get() = currentTextColor
set(@ColorInt color) {
setTextColor(color)
}
For setting ColorRes
myView.setTextColorRes(R.color.my_color)
fun TextView.setTextColorRes(@ColorRes colorRes: Int) {
val color = ContextCompat.getColor(context, colorRes)
setTextColor(color)
}
Using Adapter you can set the text color by using this code:
holder.text_view = (TextView) convertView.findViewById(R.id.text_view);
holder.text_view.setTextColor(Color.parseColor("#FF00FF"));
TextView text = new TextView(context);
text.setTextColor(Color.parseColor("any hex value of a color"));
Above code is working on my side. Here text
is a TextView on which color is needed to be set.
if you use Kotlin, there are 4 ways: (with Holder)
Use Android resource: holder.textView.setTextColor(Color.GREEN) Use RGB: holder.textView.setTextColor(Color.rgb(255, 87, 34))
3)Use Hex:
holder.textView.setTextColor(Color.parseColor("#C2185B"))
4)Use Project resource: (requires API level 23)
holder.textView.setTextColor(context.resources.getColor(R.color.colorMax,null))
From API 23 onward, getResources().getColor()
is deprecated.
Use this instead:
textView.setTextColor(ContextCompat.getColor(getApplicationContext(), R.color.color_black));
textViewStatus.setTextColor(res.getColor(R.color.green));
In Adapter you can set the text color by using this code:
holder.my_text_view = (TextView) convertView.findViewById(R.id.my_text_view);
holder.my_text_view.setTextColor(Color.parseColor("#FFFFFF"));
if you want to give color code directly then use
textView.setTextColor(Color.parseColor("#ffffff"));
or if you want to give color code from colors folder then use
textView.setTextColor(R.color.white);
I did this way: Create a XML file, called Colors in res/values folder.
My Colors.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="vermelho_debito">#cc0000</color>
<color name="azul_credito">#4c4cff</color>
<color name="preto_bloqueado">#000000</color>
<color name="verde_claro_fundo_lista">#CFDBC5</color>
<color name="branco">#ffffff</color>
<color name="amarelo_corrige">#cccc00</color>
<color name="verde_confirma">#66b266</color>
</resources>
To get this colors from the xml file, I've used this code: valor it's a TextView, and ctx it's a Context object. I'm not using it from an Activity, but a BaseAdapter to a ListView. That's why I've used this Context Object.
valor.setTextColor(ctx.getResources().getColor(R.color.azul_credito));
Hope it helps.
In order to set color of a TextView, TextView.setTextColor(R.color.YOURCOLOR)
is not enough!
It has to be used like this –
TextView myText = (TextView) findViewById(R.id.YoutTextViewID);
myText.setTextColor(getResources().getColor(R.color.YOURCOLOR);
OR
myText.setTextColor(Color.parseColor("#54D66A"));
holder.userType.setTextColor(context.getResources().getColor(
R.color.green));
Try this:
TextView textview = (TextView) findViewById(R.id.textview );
textview .setTextColor(Color.parseColor("#85F85F"));
Similarly, I was using color.xml
:
<color name="white">#ffffff</color>
<color name="black">#000000</color>
For setting the TextView
background like:
textView.setTextColor(R.color.white);
I was getting a different color, but when I used the below code I got the actual color.
textView.setTextColor(Color.parseColor("#ff6363"));
For providing rgb values: text.setTextColor(Color.rgb(200,0,0));
For parsing the color from a hex value: text.setTextColor(Color.parseColor("#FFFFFF"));
If you are in an adapter and still want to use a color defined in resources you can try the following approach:
holder.text.setTextColor(holder.text.getContext().getResources().getColor(R.color.myRed));
Success story sharing
getColor(int)
is deprecated.
