How to open a keyboard on a button, click in android?

Question

How can I open the keyboard when I press a button on Android?

I want to be like this:

Answer 1

Please, try

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

Answer 2

 InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE); imm.showSoftInput(view, flags) 

could be an example:

 InputMethodManager imm = (InputMethodManager) RouteMapActivity.this .getSystemService(Context.INPUT_METHOD_SERVICE); imm.showSoftInput(mapView, InputMethodManager.SHOW_IMPLICIT); 

Answer 3

Write this code inside the button press event for the TOGGLE keyboard:

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