Android keyboard implementation-breakpoint record

Implementation of the following dialing part

 

 

Implementation principle:

1. A Popupwindow is located in the ground (multiple imageviews are filled in)

2. When each ImageView is clicked, onKeyDown and onKeyUp are triggered.

Int keyCode = KeyEvent. KEYCODE_DEL; // here is the return key

KeyEvent keyEventDown = new KeyEvent (KeyEvent. ACTION_DOWN, keyCode );

 

KeyEvent keyEventUp = new KeyEvent (KeyEvent. ACTION_UP, keyCode );

EditNumber. onKeyDown (keyCode, keyEventDown); // editNumber is ImageView

EditNumber. onKeyUp (keyCode, keyEventUp );
