Soft Keyboard hide on backpress

问题

I need to identify the event of back press which hide the softkeyboard
I have tested by override following methods

1. onKeydown
2. onBackPressed
3. onConfigurationChanged
4. dispatchKeyEvent

But the controller is not reaching there

回答1:

Use dispatchKeyEventPreIme in subclassed EditText view:

@Override
public boolean dispatchKeyEventPreIme(KeyEvent event) {
    if(KeyEvent.KEYCODE_BACK == event.getKeyCode()) {
       //do what you need here
    }
    return super.dispatchKeyEventPreIme(event);
}
