Display Soft Keyboard Programmatically - not working

Question

I have a togglebutton in my screen. If I click on this button, I need a keyboard to show up on the screen. This is the code I have right now, but it doesnt display the keyboard as expected :(

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        keyboard = (ToggleButton) findViewById(R.id.keyboard);
        keyboard.setOnClickListener(displayKeyboard);
}

 OnClickListener displayKeyboard = new OnClickListener(){
        @Override
        public void onClick(View v) {
            if(client == null)
                   return;
            boolean on = ((ToggleButton) v).isChecked();
            if(on){ // show keyboard
                System.out.println("Togglebutton is ON");
                keyboard.requestFocus();
                InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                mgr.showSoftInput(keyboard, InputMethodManager.SHOW_IMPLICIT);
            }
            else{ // hide keyboard
                System.out.println("Togglebutton is OFF");
                InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                mgr.hideSoftInputFromWindow(keyboard.getWindowToken(), 0);          }
        }
    };

When I click the keyboard togglebutton, I see in LogCat that it goes into the if/else block, but otherwise doesnt display any keyboard on screen. can someone please help?

Answer 1

With the showSoftInput you are trying to focus your keyboard button and to start sending keyboard events to it, but it is not focusable. Make it focusable like this (in your onCreate):

keyboard.setFocusable(true);
keyboard.setFocusableInTouchMode(true);

You can try this (In UTILITY class):

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

     public static void showSoftKeyboard(Activity activity, View focusedView)
     {
         InputMethodManager inputMethodManager = (InputMethodManager)  activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
         inputMethodManager.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT);
     }
