Question

我正在使用YoutubePlayerFragment课程来播放视频。我想添加一个GestureListener，但它们不是设置手势检测器的方法。我试过了：

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="0dip"
    android:id="@+id/player_holder"
    android:visibility="gone"
    android:layout_weight="40">

    <RelativeLayout
        android:layout_width="match_parent"
        android:duplicateParentState="true"
        android:layout_height="match_parent">

        <fragment
            android:id="@+id/player_fragment"
            android:duplicateParentState="true"
            android:name="com.google.android.youtube.player.YouTubePlayerFragment"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

        <LinearLayout
            android:layout_width="match_parent"
            android:id="@+id/gestureCatcher"
            android:orientation="vertical"
            android:duplicateParentState="true"
            android:layout_height="match_parent" />

    </RelativeLayout>
</LinearLayout>

和

    private static final int SWIPE_MIN_DISTANCE       = 120;
    private static final int SWIPE_MAX_OFF_PATH       = 250;
    private static final int SWIPE_THRESHOLD_VELOCITY = 200;
    private GestureDetector gestureDetector;
    View.OnTouchListener gestureListener;

    class MyGestureDetector extends GestureDetector.SimpleOnGestureListener {

        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
            try {
                if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) return false;
                // right to left swipe
                if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                    Toast.makeText(NonStopActivity.this, "Left Swipe", Toast.LENGTH_SHORT)
                            .show();
                } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                    Toast.makeText(NonStopActivity.this, "Right Swipe", Toast.LENGTH_SHORT)
                            .show();
                }
            } catch (Exception e) {
                // nothing
            }
            return false;
        }

        @Override
        public boolean onDown(MotionEvent e) {
            return true;
        }
    }

这就是我将手势检测器设置为LinearLayout

的方法

gestureDetector = new GestureDetector(this, new MyGestureDetector());
gestureListener = new View.OnTouchListener() {
    public boolean onTouch(View v, MotionEvent event) {
        return gestureDetector.onTouchEvent(event);
    }
};

LinearLayout gestureCatcher = (LinearLayout) findViewById(R.id.gestureCatcher);
gestureCatcher.setOnTouchListener(gestureListener);

但叠加层阻止了YoutubePlayerFragment。有解决这个问题的方法吗？

Answer 1

您可以在YouTubePlayerFragment对象上设置手势监听器。尝试使用...

在onCreate方法中进行设置

YouTubePlayerFragment frag = (YouTubePlayerFragment) 
    getFragmentManager().findFragmentById(R.id._________)
View v = frag.getView();
v.setOnTouchListener(new View.OnTouchListener() {
    //your code goes here
}

只要隐藏了搜索栏和播放按钮叠加层，它就会起作用。如果他们不是该重叠消耗手势。这很烦人，但除了将玩家风格设置为无铬外，我不知道如何解决它。这可以使用mPlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.CHROMELESS);

完成

当然，这意味着您无法拥有播放按钮或搜索栏，但您可以以某种方式实现自己的。

对于遇到相同问题的人，最好的方法是扩展public class DraggableYouTubePlayerFragment extends YouTubePlayerFragment { @Override public View onCreateView(LayoutInflater layoutInflater, ViewGroup viewGroup, Bundle bundle) { final View view = super.onCreateView(layoutInflater, viewGroup, bundle); FrameLayout wrapper = new FrameLayout(viewGroup.getContext()) { @Override public boolean onInterceptTouchEvent(MotionEvent ev) { return true; } }; wrapper.addView(view); return wrapper; } }：

loadFooter()
