android hide keyboard method(error when focus lose)

Question

I have some Fragments with EditTexts. When I write text in EditText on the first fragment I open next fragment. How can I hide the keyboard?

I am doing this:

public static void hideSoftKeyboard(Activity activity) {
        InputMethodManager inputMethodManager = (InputMethodManager)  activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
    }

but if i return on first fragment and again open next fragment focus lose. and i have error.

I found

EditText myEditText = (EditText) findViewById(R.id.myEditText);  
InputMethodManager imm = (InputMethodManager)getSystemService(
      Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(myEditText.getWindowToken(), 0);

But I have many fields on the fragment and many fragments with fields. I don't want duplicate code.

My error is:

You could pass a View to your hideSoftKeyboard method and get a context from a View's getContext().

public static void hideSoftKeyboard(View view) {
    InputMethodManager inputMethodManager =
        (InputMethodManager) view.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
    inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
  }

Need to say passing an Activity around could be a bad idea because this may entail memory leaks which are hard to debug and fix.

try

    public static void hideSoftKeyboard(Activity activity, View view) {
          if(activity!= null && !activity.isFinish() && view != null) 
          {
             InputMethodManager inputMethodManager = (InputMethodManager)  activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
             inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
          }
    }

Use this code

private void hideSoftKeyBoard(ScrollView view){
    InputMethodManager inputManager = (InputMethodManager)getActivity().getSystemService(Activity.INPUT_METHOD_SERVICE);
    inputManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
}

This is working for me.

Try following working for me

public static void hideSoftKeyboard(Activity activity) {
    if (null != activity.getWindow()){
    activity.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
  }
}

 public static void hideKeyboard(Activity activity) {
    // Check if no view has focus:
    View view = activity.getCurrentFocus();
    if (view != null) {
        InputMethodManager inputManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
        inputManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
    }
}
