我想在我的Android应用程序中捕获一个LongPress-Gesture,但是this.gestureDetector.onTouchEvent(event)总是返回false。我在LogCat中得到了“Longpress detect”,但是onTouchEvent总是返回false - 这里有什么想法吗?
final GestureDetector gestureDetector = new GestureDetector(this.getContext(),
new GestureDetector.SimpleOnGestureListener() {
@Override
public void onLongPress(MotionEvent event) {
Log.e(TAG, "Longpress detected");
}
});
@Override
public boolean onTouchEvent(MotionEvent event) {
boolean test = this.gestureDetector.onTouchEvent(event);
Log.v(TAG, Boolean.toString(test)); // test is _always_ false
if (test) {
// Do something
return test;
}
return super.onTouchEvent(event);
}
答案 0 :(得分:0)
因为onLongPress没有返回值,所以它被定义为void。
public void onLongPress(MotionEvent event) {
Log.e(TAG, "Longpress detected");
}
