You can handle the back button being pressed by using the following method:
// When not using fragments @Override public void onBackPressed() { // Check if no view has focus: View view = this.getCurrentFocus(); if (view != null) { InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(view.getWindowToken(), 0); } } The code inside the onBackPressed method was found here; Close/hide the Android Soft Keyboard
// When using a fragment fragment.getView().setFocusableInTouchMode(true); fragment.getView().requestFocus(); fragment.getView().setOnKeyListener( new OnKeyListener() { @Override public boolean onKey( View v, int keyCode, KeyEvent event ) { if( keyCode == KeyEvent.KEYCODE_BACK ) { // Check if no view has focus: View view = this.getCurrentFocus(); if (view != null) { InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(view.getWindowToken(), 0); } } return false; } } );

I need to handle back button in Fragment. Fragment not has method "onBackPressed"

Okay i will look into solutions for that. In the mean time accept my edit so other users can see that a fragment is being used

When keyboard is show and I click back button the method "onKey(...)" not call.
You can use the onKeyPreIme method to handle click of the button.
@Override public boolean onKeyPreIme(int keyCode, KeyEvent event) { return true; }
