How to hide the soft keyboard inside a fragment?

As long as your Fragment creates a View, you can use the IBinder (window token) from that view after it has been attached. For example, you can override onActivityCreated in your Fragment:

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    final InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(getView().getWindowToken(), 0);
}

---

Nothing but the following line of code worked for me:

getActivity().getWindow().setSoftInputMode(
            WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

---

If you add the following attribute to your activity's manifest definition, it will completely suppress the keyboard from popping when your activity opens. Hopefully this helps:

(Add to your Activity's manifest definition):

android:windowSoftInputMode="stateHidden"

---

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_my, container,
                false);
        someClass.onCreate(rootView);
        return rootView;
    }

Keep an instance of my root view in my class

View view;

public void onCreate(View rootView) {
    view = rootView;

Use the view to hide the keyboard

 public void removePhoneKeypad() {
    InputMethodManager inputManager = (InputMethodManager) view
            .getContext()
            .getSystemService(Context.INPUT_METHOD_SERVICE);

    IBinder binder = view.getWindowToken();
    inputManager.hideSoftInputFromWindow(binder,
            InputMethodManager.HIDE_NOT_ALWAYS);
}

---

Exception for DialogFragment though, focus of the embedded Dialog must be hidden, instead only the first EditText within the embedded Dialog

this.getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

---

This code works for fragments:

getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

---

Use this static method, from anywhere (Activity / Fragment) you like.

public static void hideKeyboard(Activity activity) {
    try{
        InputMethodManager inputManager = (InputMethodManager) activity
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        View currentFocusedView = activity.getCurrentFocus();
        if (currentFocusedView != null) {
            inputManager.hideSoftInputFromWindow(currentFocusedView.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
        }
    }catch (Exception e){
        e.printStackTrace();
    }
}

If you want to use for fragment just call hideKeyboard(((Activity) getActivity())).

this will be work in my case when in tabs i switch from one fragment to another fragments

@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
    super.setUserVisibleHint(isVisibleToUser);
    if (isVisibleToUser) {
        try {
            InputMethodManager mImm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
            mImm.hideSoftInputFromWindow(getView().getWindowToken(), 0);
            mImm.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);
        } catch (Exception e) {
            Log.e(TAG, "setUserVisibleHint: ", e);
        }
    }
}

---

Solution that worked for me in fragments:

fun hideKeyboard(){
    val imm = requireActivity().getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(view?.windowToken, 0)
}

and in an activity:

fun hideKeyboard(){
    val inputManager: InputMethodManager = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    inputManager.hideSoftInputFromWindow(currentFocus?.windowToken, InputMethodManager.SHOW_FORCED)
}

---

Nothing of this worked on API27. I had to add this in the container of the layout, for me it was a ConstraintLayout:

<android.support.constraint.ConstraintLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:focusable="true"
            android:focusableInTouchMode="true"
            android:focusedByDefault="true">

//Your layout

</android.support.constraint.ConstraintLayout>

This worked for me in Kotlin class

fun hideKeyboard(activity: Activity) {
    try {
        val inputManager = activity
            .getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        val currentFocusedView = activity.currentFocus
        if (currentFocusedView != null) {
            inputManager.hideSoftInputFromWindow(currentFocusedView.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
        }
    } catch (e: Exception) {
        e.printStackTrace()
    }

}

---

Use this code in any fragment button listener:

InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(getActivity().INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);

---

Kotlin code

val imm = requireActivity().getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(requireActivity().currentFocus?.windowToken, 0)

---

Just add this line in you code:

getActivity().getWindow().setSoftInputMode(
                WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

---

In Kotlin:

(activity?.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager).hideSoftInputFromWindow(view?.windowToken,0)

---

Use this:

Button loginBtn = view.findViewById(R.id.loginBtn);
loginBtn.setOnClickListener(new View.OnClickListener() {
   public void onClick(View v) {
      InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(getActivity().INPUT_METHOD_SERVICE);
      imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
   }
});

---

IN BEGINNING

in fragment, below code(use in onActivityCreated) force to hide keyboard in beginning:

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    Objects.requireNonNull(getActivity()).getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
}

DURING FRAGMENT (if need)

and also if you have edittext or sth different needs keyboard, and wanna hide the keyboard when pressing outside the keyboard(in my case I have LinearLayout class in xml), first initialize the layout:

LinearLayout linearLayout;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    
    View view = inflater.inflate(R.layout.<your fragment xml>, container, false);

    linearLayout= view.findViewById(R.id.linearLayout);
    ...
    return view;
}

then, you need to below code(use in onViewCreated):

@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {

    linearLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view12) {
            try {
                InputMethodManager inputMethodManager = (InputMethodManager) Objects.requireNonNull(VideoFragment.this.getActivity()).getSystemService(INPUT_METHOD_SERVICE);
                assert inputMethodManager != null;
                inputMethodManager.hideSoftInputFromWindow(VideoFragment.this.getActivity().getCurrentFocus().getWindowToken(), 0);

            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });

}

You can use two ways:

You can create a method inside fragment, but first you must create a View attribute and put the inflater result inside it before it returns in onCreateView:

1° Open your Fragment class. Create attribute

private View view;

2° assign the 'view' attribute the inflater in onCreateView

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
                view = inflater.inflate(R.layout.your_activity_main, container, false);
                return view;
}

3° create the method 'hideKeyboard'

public void hideKeyboard(Activity activity) {
        try{
            InputMethodManager inputManager = (InputMethodManager) activity
                    .getSystemService(view.getContext().INPUT_METHOD_SERVICE);
            View currentFocusedView = activity.getCurrentFocus();
            if (currentFocusedView != null) {
                inputManager.hideSoftInputFromWindow(currentFocusedView.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
            }
        }catch (Exception e){
            e.printStackTrace();
        }
    }

5° Now just call the method

    hideKeyboard(getActivity());

If that doesn't solve your problem, you can try passing the MainActivity class as an object to close the keyboard inside the Frament class

1° In YourClassActivity that you instantiated Fragment, create the method 'hideKeyboard'

public class YourClassActivity extends AppCompatActivity {
    public static void hideKeyboard(Activity activity) {
            InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
            //Find the currently focused view, so we can grab the correct window token from it.
            View view = activity.getCurrentFocus();
            //If no view currently has focus, create a new one, just so we can grab a window token from it
            if (view == null) {
                view = new View(activity);
            }
            imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
        }
}

2° Implement the 'Serializable' interface in your Activity that instantiates the Fragment

public class YourClassActivity extends AppCompatActivity implements Serializable {
...
}

3° When you instantiate the Frament in the Activity, you must pass the arguments to that Fragment, which will be the Activity class itself

Bundle bundle = new Bundle();
bundle.putSerializable("activity", this);
YourClassFragment fragment = new YourClassFragment();
fragment.setArguments(bundle);

4° Now let's go to your Fragment class. Create attribute view and activity.

private View view;  
private Activity activity;

5° Assign the 'view' attribute the inflater in onCreateView. Here you will retrieve the Activity object that was passed as a parameter of this Fragment

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
            view = inflater.inflate(R.layout.your_activity_main, container, false);
            activity = (Activity) getArguments().getSerializable("obj");
    
            return view;
    }

6° Now just call the method

hideKeyboard(activity);

I did all steps but there is something missing I hide the keyboard in fragments with that method

fun hideKeyBoard(view: View) {
        val inputManager =
            requireActivity().getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        inputManager.hideSoftInputFromWindow(
            view.windowToken,
            SOFT_INPUT_STATE_ALWAYS_HIDDEN
        )
    }

but still when I open the fragment the keyboard open also after a lot of search I found the problem I must put those code in my xml layout root

android:focusable="true"
android:focusableInTouchMode="true" 

Note: If you delete above method and just put the attributes in root layout, it will work fine.
