I don't know how to send a backspace key event to a EditText
from my own button. Here is what i tried:
Button backSpace=(Button)findViewById(R.id.backSpace_tab);
backSpace.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
text.dispatchKeyEvent(new KeyEvent(KeyEvent.KEYCODE_DEL,KeyEvent.KEYCODE_P));
}
});
From the Android developer docs:
public KeyEvent (int action, int code)
Create a new key event.
Parameters
action Action code: either ACTION_DOWN, ACTION_UP, or ACTION_MULTIPLE.
code The key code
The first parameter should be an action code. In your case you should use ACTION_DOWN, because you want to simulate a keypress:
public static final int ACTION_DOWN
getAction() value: the key has been pressed down.
So this should work:
@Override
public void onClick(View v)
{
text.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DEL));
}
