Back Taste long pressed

To enable the new behavior in your app you must set android:targetSdkVersion in your manifest to 5 or greater.

@Override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_CALL) {
// a long press of the call key.
// do our work, returning true to consume it. by
// returning true, the framework knows an action has
// been performed on the long press, so will set the
// canceled flag for the following up event.
return true;
}
return super.onKeyLongPress(keyCode, event);
}
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_CALL && event.isTracking()
&& !event.isCanceled()) {
// if the call key is being released, AND we are tracking
// it from an initial key down, AND it is not canceled,
// then handle it.
return true;
}
return super.onKeyUp(keyCode, event);
}
Note that the above code assumes we are implementing different behavior for a key that is normally processed by the framework. If you want to implement long presses for another key, you will also need to override onKeyDown to have the framework track it:
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_0) {
// this tells the framework to start tracking for
// a long press and eventual key up. it will only
// do so if this is the first down (not a repeat).
event.startTracking();
return true;
}
return super.onKeyDown(keyCode, event);
}
