我想在我的视图中检测onTouchEvent函数的触摸边缘,但是getEdgeFlags()总是在我的Nexus S 4.1.1中返回0,有人可以帮助我吗?谢谢你。
@Override
public boolean onTouchEvent(MotionEvent event) {
int edgeFlags = event.getEdgeFlags();
//edgeFlags alway 0!
switch (edgeFlags) {
case MotionEvent.EDGE_LEFT:
Log.i("tag", "EDGE_LEFT");
break;
case MotionEvent.EDGE_RIGHT:
Log.i("tag", "EDGE_RIGHT");
break;
case MotionEvent.EDGE_TOP:
Log.i("tag", "EDGE_TOP");
break;
case MotionEvent.EDGE_BOTTOM:
Log.i("tag", "EDGE_BOTTOM");
break;
default:
Log.i("tag", "" + edgeFlags);
break;
}
return super.onTouchEvent(event);
}
答案 0 :(得分:1)
我通过添加四个按钮触发四个方向来解决问题!
