Question

这是我的布局：

<?xml version="1.0" encoding="utf-8"?><!-- Style Theme.Transparent -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearLayoutVideo"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:weightSum="1"
    android:focusable="true"
    android:clickable="true">

    <VideoView
        android:id="@+id/videoView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="0.75"
        android:clickable="true"
        android:focusable="true" />

</LinearLayout>

我将onclicklistener设置为父视图和子视图：

linearLayout.setOnClickListener(myOnlyhandler);
videoView.setOnClickListener(myOnlyhandler);

我只获得视频观看的点击事件。我想要的是知道用户是否点击进入视频视图或外部（父）并执行不同的操作。我该如何得到这种行为？

前段时间我实现了一个提供此类功能的Activity基类。您只需注册一个自定义OnTouchOutsideViewListener，一旦用户在安装了监听器后触摸您的视图，该自定义setOnTouchOutsideViewListener就会收到通知。只需在您的活动实例上调用class YourActivity extends Activity { private View mTouchOutsideView; private OnTouchOutsideViewListener mOnTouchOutsideViewListener; /** * Sets a listener that is being notified when the user has tapped outside a given view. To remove the listener, * call {@link #removeOnTouchOutsideViewListener()}. * <p/> * This is useful in scenarios where a view is in edit mode and when the user taps outside the edit mode shall be * stopped. * * @param view * @param onTouchOutsideViewListener */ public void setOnTouchOutsideViewListener(View view, OnTouchOutsideViewListener onTouchOutsideViewListener) { mTouchOutsideView = view; mOnTouchOutsideViewListener = onTouchOutsideViewListener; } public OnTouchOutsideViewListener getOnTouchOutsideViewListener() { return mOnTouchOutsideViewListener; } @Override public boolean dispatchTouchEvent(final MotionEvent ev) { if (ev.getAction() == MotionEvent.ACTION_DOWN) { // Notify touch outside listener if user tapped outside a given view if (mOnTouchOutsideViewListener != null && mTouchOutsideView != null && mTouchOutsideView.getVisibility() == View.VISIBLE) { Rect viewRect = new Rect(); mTouchOutsideView.getGlobalVisibleRect(viewRect); if (!viewRect.contains((int) ev.getRawX(), (int) ev.getRawY())) { mOnTouchOutsideViewListener.onTouchOutside(mTouchOutsideView, ev); } } } return super.dispatchTouchEvent(ev); } /** * Interface definition for a callback to be invoked when a touch event has occurred outside a formerly specified * view. See {@link #setOnTouchOutsideViewListener(View, OnTouchOutsideViewListener).} */ public interface OnTouchOutsideViewListener { /** * Called when a touch event has occurred outside a given view. * * @param view The view that has not been touched. * @param event The MotionEvent object containing full information about the event. */ public void onTouchOutside(View view, MotionEvent event); } }即可。

您可以将此代码粘贴到现有的活动类中，也可以创建一个可以在整个项目中重复使用的基本活动类。
