GestureDetector不捕获所有MotionEvents

时间：2017-10-29 19:55:04

标签： android motionevent

我对Android开发很新。我正在尝试创建一个应用来捕获用户从触摸屏数据中滑动的行为。我按照Android tutorial here中的代码示例，在＆＃34;检测所有支持的手势＆＃34;部分中进行了操作。当我使用该应用程序时，我可以看到Logger输出正在响应我的触摸输入。具体来说，在我的onScroll函数中，我有一行：

Log.d(DEBUG_TAG, "onScroll: " + event1.toString() + event2.toString());

正如预期的那样，它向我展示了连接的两个事件。这是一个ACTION_DOWN事件和一个ACTION_MOVE事件，我猜测它分别代表刷卡开始的点和它注册的最后一个点。

问题出在这里：在所有函数中，我只是将MotionEvent添加到ArrayList中，目的是捕获活动的所有事件，最后，当用户单击Button时，我想要做一些事情。事件清单。我尝试在此时进行调试（即onClick）以检查ArrayList的状态，我注意到它缺少所有ACTION_MOVE事件，即来自onScroll的event2，Logger正确地向我展示了它。

我对此非常困惑。我错过了什么？为什么我无法捕获Logger显示的所有事件？这是活动生命周期产生的问题吗？我的代码粘贴在下面。谢谢你的帮助。

试试这个。

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        this.mDetector.onTouchEvent(event);
        // Be sure to call the superclass implementation
        if(event.action == MotionEvent.ACTION_MOVE){
              Log.d("here");
        }

        return super.onTouchEvent(event);
    }
