This annotation will trigger an event when a View receives or loses focus.

How to use

The method should be this way:

public void onFocusChanged(boolean hasFocus)
public void onFocusChanged(View v, boolean hasFocus)

Example

@OnFocusChanged(R.id.my_view)
public void onFocusChanged(boolean hasFocus) {
    Toast.makeText(this, "View has focus: $hasFocus", Toast.LENGTH_SHORT).show();
}
