VideoView上的MediaController定位

android

Mark B · 技术社区 · 14 年前

我有一个视频视图,它占据了活动的上半部分,在屏幕的下半部分显示一些图像和文本。活动开始时,我正在视频视图中播放rtsp视频流。我已通过以下代码将MediaController连接到VideoView:

    MediaController controller = new MediaController(this);
    controller.setAnchorView(this.videoView);
    controller.setMediaPlayer(this.videoView);
    this.videoView.setMediaController(controller);

当我点击VideoView在屏幕上调出MediaController时,我期望播放控件出现在VideoView的底部区域(MediaController的底部甚至与VideoView的底部重叠)。相反,MediaController在屏幕的下方弹出,覆盖了视频视图下方的一些图形和文本。

坦白说,我只会写我自己的控制器。事实上, I did once .

话说回来,试试看 setAnchorView() --通过我对源代码的阅读 MediaController

不

video.setOnPreparedListener(new OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer mp) {
            mp.setOnVideoSizeChangedListener(new OnVideoSizeChangedListener() { 
            @Override
            public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {
                /*
                 * add media controller
                 */
                mc = new MediaController(YourActivity.this);
                video.setMediaController(mc);
                /*
                 * and set its position on screen
                 */
                mc.setAnchorView(video);
            }
        });
    }
});

我找到了很简单的解决办法。

    MediaController mc = new MediaController(context);
    videoView.setMediaController(mc);

    FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
    lp.gravity = Gravity.BOTTOM;
    mc.setLayoutParams(lp);

    ((ViewGroup) mc.getParent()).removeView(mc);

    ((FrameLayout) findViewById(R.id.videoViewWrapper)).addView(mc);

编辑:自从我发布了这个答案,我遇到了很多问题,让它隐藏和控制它的大小,所以我最终做的是我只是创建了我自己的控制,我可以动画和工作没有头痛的布局

下面是我在不编写完整的自定义控制器(仅重写 onSizeChanged (要向上移动锚点的MediaController的名称):

使用FrameLayout作为MediaContoller的锚点,将其与VideoView打包,如下所示:

<RelativeLayout
    android:id="@+id/videoLayout"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1.3"
    android:layout_gravity="center"
    android:background="#000000">

    <VideoView
        android:id="@+id/videoView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerInParent="true" />

    <FrameLayout android:id="@+id/controllerAnchor"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true" 
        android:layout_alignParentRight="true" 
        />

</RelativeLayout>

创建自定义的MediaController,当FrameLayout的大小更改时,它将向上移动FrameLayout(锚定到它的MediaController将跟随它):

public class MyMediaController extends MediaController
{
    private FrameLayout anchorView;


    public MyMediaController(Context context, FrameLayout anchorView)
    {
        super(context);
        this.anchorView = anchorView;       
    }

    @Override
    protected void onSizeChanged(int xNew, int yNew, int xOld, int yOld)
    {
        super.onSizeChanged(xNew, yNew, xOld, yOld);

        RelativeLayout.LayoutParams lp = (RelativeLayout.LayoutParams) anchorView.getLayoutParams();
        lp.setMargins(0, 0, 0, yNew);

        anchorView.setLayoutParams(lp);
        anchorView.requestLayout();
    }       
}

使用上面的自定义控制器代替标准控制器,然后将其锚定到FrameLayout:

protected void onCreate(Bundle savedInstanceState)
{

    //...

    videoView = (VideoView) findViewById(R.id.videoView1);      
    videoController = new MyMediaController(this, (FrameLayout) findViewById(R.id.controllerAnchor));               
    videoView.setMediaController(videoController);      

    //...       
}

public void onPrepared(MediaPlayer mp) 
{
    videoView.start();              

    FrameLayout controllerAnchor = (FrameLayout) findViewById(R.id.controllerAnchor);
    videoController.setAnchorView(controllerAnchor);                
}

mediaController.setPadding(0, 0, 0, px);

将mediacontroller视图设置为所需位置。希望这对你有帮助。

这是我第一次在stackoverflow中回答问题,我只在FrameLayout中插入了一个VideoView,两种方法都是相同的。MediaController将位于FrameLayout的底部。这对我有用:

主要_活动.XML:

           <FrameLayout      
            android:id="@+id/frame_layout_video"
            android:layout_centerHorizontal="true"
            android:layout_width="wrap_content"
            android:layout_height="400dp">

            <VideoView
                android:id="@+id/video_select"
                android:layout_width="wrap_content"
                android:layout_height="400dp"
                android:adjustViewBounds="true"
                android:clickable="true"
                android:scaleType="centerCrop"
                 />

        </FrameLayout>

@Override
public void onClick(View v) {
    int i = v.getId();

    if(i == R.id.select_video){
        selectVideo();
    }

private void selectVideo(){
    //this code is to get videos from gallery:
    Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT);
    galleryIntent.addCategory(Intent.CATEGORY_OPENABLE);
    galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
    galleryIntent.setType("video/*");
    startActivityForResult(galleryIntent, GALLERY_REQUEST);

    MediaController mediaController = new MediaController(this);
    mediaController.setAnchorView(mVideo);
    //mVideo is the VideoView where I insert the video
    mVideo.setMediaController(mediaController);
    mVideo.pause();
}


@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    switch (requestCode) {
        case 1:
            if (resultCode == RESULT_OK) {
                mVideoUri = data.getData();
                mVideo.setVideoURI(mVideoUri);
                mVideo.start();
            }
    }
}

我是用包装纸做的 VideoView 内部 LinearView 以至于有 layout_width="match_parent" 所以它总是延伸到屏幕的范围,但是 layout_height="wrap_content" 因此,线性视图的高度始终固定为内容的高度。这样,当视频播放时,控件总是与视频视图一起放置。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    tools:context=".DisplayClipActivity">

    <VideoView android:id="@+id/episode_clip"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>
</LinearLayout>

// create media controller
val mediaController = MediaController(this@DisplayClipActivity)
mediaController.setAnchorView(videoView)
mediaController.setMediaPlayer(videoView)

// video view
videoView.setVideoURI(uri)
videoView.setMediaController(mediaController)
videoView.start()
