我试图扩展GestureDetector.SimpleOnGestureListener
类以检测Dialog
上的手势,它对我有用,但它没有检测到任何按钮上的单击,向下,滚动等事件,复选框,对话框中的单选按钮,它只触摸对话框内的白色区域时检测这些事件。任何人都知道如何在对话框中检测各种按钮和其他控件上的手势?
以下是我的对话框和手势监听器的代码片段:
public class SimpleDialog extends Dialog {
private GestureDetector gestureDetector;
public SimpleDialog(Context context) {
super(context);
gestureDetector = new GestureDetector(context, new MyGestureDetector());
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.dialog_simple);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
return gestureDetector.onTouchEvent(event);
}
private class MyGestureDetector extends GestureDetector.SimpleOnGestureListener {
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
System.out.println( "touch event onFling()");
return false;
}
MyGestureDetector() {
super();
}
@Override
public boolean onSingleTapUp(MotionEvent e) {
System.out.print("touch event onSingleTapUp()");
return super.onSingleTapUp(e);
}
@Override
public void onLongPress(MotionEvent e) {
super.onLongPress(e);
}
@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
System.out.println("touch event onScroll()");
return super.onScroll(e1, e2, distanceX, distanceY);
}
@Override
public void onShowPress(MotionEvent e) {
super.onShowPress(e);
}
@Override
public boolean onDown(MotionEvent e) {
System.out.println("touch event onDown()");
return true;
}
@Override
public boolean onDoubleTap(MotionEvent e) {
return super.onDoubleTap(e);
}
@Override
public boolean onDoubleTapEvent(MotionEvent e) {
return super.onDoubleTapEvent(e);
}
@Override
public boolean onSingleTapConfirmed(MotionEvent e) {
return super.onSingleTapConfirmed(e);
}
@Override
public boolean onContextClick(MotionEvent e) {
return super.onContextClick(e);
}
}
}
