Force keyboard opening

Question

I have this dialog in my application

public void alertaLocalizar(View v) {
    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view = inflater.inflate(R.layout.alerta_comum, null);


    Dialog localizar = new Dialog(this);
    localizar.requestWindowFeature(Window.FEATURE_NO_TITLE);
    localizar.setContentView(view);
    localizar.show();
    }

}

And I wanted to force open the keyboard as soon as it was opened, how can I do that?

And taking advantage of the question, I would like to know how to use the keyboard OK button to have the same effect as the Alert OK button and not close the keyboard.

Answer 1

To force the keyboard open use this code :

InputMethodManager imm = (InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);

To hide the keyboard put this code inside the button :

InputMethodManager imm = (InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);

Take a look at the documentation of InputMethodManager for better understanding :

https://developer.android.com/reference/android/view/inputmethod/InputMethodManager.html

And complementing with your question about where to put the code,I suggest you create an event to deal with over the keyboard OK button to hide the keyboard through the code I posted.

Example of the Enter button with Keyevent event :

    public boolean onKey(View v, int keyCode, KeyEvent event) {
        switch (keyCode) {
            case KeyEvent.KEYCODE_ENTER:
          /*Coloque aqui o que irá acontecer caso pressionado o botão*/
          return true;
        }
    return false;
}

Take a look at the Keyevent documentation that will help you do this:
