MediaController定位在VideoView上
我有一个VideoView，占据纵向上半部分的活动，屏幕的下半部分显示一些图像和文字。 当Activity开始时，我在video视图中播放一个rtspvideostream。 我通过以下代码将MediaController附加到VideoView：
MediaController controller = new MediaController(this); controller.setAnchorView(this.videoView); controller.setMediaPlayer(this.videoView); this.videoView.setMediaController(controller); 当我点击VideoView来调出屏幕上的MediaController时，我预计播放控件会出现在VideoView的底部区域（MediaController的底部，即使是VideoView的底部）。 相反，MediaController在屏幕上向下popup，叠加在VideoView下面的一些graphics和文本。
是否有一些额外的步骤，我需要采取的MediaController出现在我想要它在屏幕上？
坦率地说，我只是写我自己的控制器。 其实我做过一次 。
也就是说，尝试setAnchorView() – 通过阅读源代码， MediaController将出现在任何锚视图的底部。
设置锚点视图只有在video视图大小已知的情况下才会起作用 – 不会在初始化时显示。 但是你可以做这样的事情：
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); } }); } });
我发现真正简单的解决scheme
只需将video视图包装在FrameLayout中，然后就可以从代码中将MediaController添加到该FrameLayout中，如下所示：
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：因为我发布这个答案，我遇到了很多问题，让它隐藏和控制其大小，所以我最终做的是我刚刚创build我自己的布局与控制，我可以动起来，没有头痛
我最近遇到了同样的问题，使用setAnchorView（videoView）将控制器完全置于VideoView下方，而不是hover在它的底部区域。 我的VideoView是上面三分之一的屏幕，所以控制器最终覆盖VideoView下的任何View。
下面是我最终做到这一点，而不用编写成熟的自定义控制器（只onSizeChanged MediaController的SizeChanged来移动锚点）：
使用FrameLayout作为MediaContoller的锚点，将其与VideoView一起包装如下：
<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build自定义MediaController，当其大小更改时，将向上移动FrameLayout（随后将绑定MediaController）：
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的控制器，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); }
我使用这个代码来解决它。
mediaController.setPadding(0, 0, 0, px);
将媒体控制器视图设置为您想要的位置。 希望这对你有所帮助。

这是我第一次在stackoverflow中回答一个问题，我只在一个FrameLayout中插入一个VideoView同样的措施。 MediaController将位于FrameLayout的底部。 这对我工作：
main_activity.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>
MainActivity.java：
@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(); } } }
