show keyboard programmatically Android

Question

Is there a way to show keyboard in an Activity above Android O version? I have the following code:

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

It works 'only' for below Android O Version.

Answer 1

I got 2 options for you. First, you can use RequestFocus

editText.requestFocus();

Second, you can execute this code to show the keyboard for a specific EditText

android.view.inputmethod.InputMethodManager imm = (android.view.inputmethod.InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(editText, android.view.inputmethod.InputMethodManager.SHOW_IMPLICIT);

Extra point, use this to hide the keyboard:

android.view.View view = this.getCurrentFocus();   
android.view.inputmethod.InputMethodManager imm = (android.view.inputmethod.InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);

Note: every code here is tested and working.

Answer 2

To show keyboard,

InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

If you want to focus to a editText, use

editText.requestFocus();

To hide keyboard,

InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(editText.getWindowToken(), 0);
