You can extend the MediaController class and programmatically set an instance of it to a VideoView class:

<pre><code>import android.content.Context;
import android.util.AttributeSet;
import android.widget.MediaController;

public class MyMediaController extends MediaController {
 public MyMediaController(Context context, AttributeSet attrs) {
 super(context, attrs);
 }

 public MyMediaController(Context context, boolean useFastForward) {
 super(context, useFastForward);
 }

 public MyMediaController(Context context) {
 super(context);
 }

 @Override
 public void show(int timeout) {
 super.show(0);
 }

}
</code></pre>

Here's the usage:

<pre><code>VideoView myVideoView = (VideoView) findViewById(R.id.my_video_view);
MediaController mc = new MyMediaController(myVideoView.getContext());
mc.setMediaPlayer(myVideoView);
myVideoView.setMediaController(mc);
</code></pre>

blocks|key|1062163|text|你需要做的是，重写自定义控制器中的hide方法，什么也不做。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1062164|public+class+MyMediaController+extends+MediaController+{
..
@Override
++++public+void+hide()+{
++++++++//+Do+nothing+here+in+order+to+always+show

++++}
...
}|code-block|syntax|javascript|1062165|PS:你仍然需要点击视频来显示媒体控制器。|1062166|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

What you need to do is, overrride the hide method in the custom controller and do nothing. 

<pre><code>public class MyMediaController extends MediaController {
..
@Override
 public void hide() {
 // Do nothing here in order to always show

 }
...
}
</code></pre>

PS: You still need to click on the video to show the media controller.

blocks|key|847847|text|您还可以内联创建一个匿名类并覆盖此处的hide方法，而不必为它创建一个全新的类：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|847848|mediaController+=+new+MediaController(this)+{

You can also create an anonymous class inline and override the hide method there instead of having to create a whole new class for it:

<pre><code>mediaController = new MediaController(this) {
 @Override
 public void hide() {
 //Do not hide.
 }
};
</code></pre>

blocks|key|847903|text|您可以创建匿名内联类并覆盖某些方法。您需要重写hide方法，并且在其中什么也不做。您还需要重写dispatchKeyEvent方法以检查back键按下并调用super.hide()。否则，按下back时，控制器不会隐藏，活动无法关闭。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|847904|+mediaController+=+new+MediaController(this){

You can create anonymous class inline and override certain methods. You need to override the hide method and do nothing in there. You also need to override the dispatchKeyEvent method to check for back key press and call the super.hide(). Otherwise on back press the controller wont hide and the activity cannot be closed.

<pre><code> mediaController = new MediaController(this){
 @Override
 public void hide() {
 // TODO Auto-generated method stub
 //do nothing
 }

 @Override
 public boolean dispatchKeyEvent(KeyEvent event) {

 if(event.getKeyCode() == KeyEvent.KEYCODE_BACK) {

 if (mediaPlayer != null) {
 mediaPlayer.reset();
 mediaPlayer.release();
 mediaPlayer = null;
 }
 super.hide();
 Activity a = (Activity)getContext();
 a.finish();

 }
 return true;
 }
 };
</code></pre>

This may be an old thread, but still unanswered, try this : 

<pre><code>final MediaController mediaController = new MediaController(this);
mediaController.setAlwaysDrawnWithCacheEnabled(true);
mediaController.setAnchorView(vView);
mediaController.requestFocus(); 
 vView.setOnPreparedListener( new OnPreparedListener() {

 public void onPrepared(MediaPlayer mp) {
 mediaController.show( 0 );
 }
 });

vView.setVideoPath(Preview_Path);
vView.setMediaController(mediaController);
vView.start(); 
</code></pre>

theres a comment inside the MediaController Class "show" method

<pre><code>**Use 0 to show
* the controller until hide() is called**
</code></pre>

so using 900000 or larger value wont help.
hope it helps you.

I wanted to fade the controller for videos and always show it for audio. This worked

<pre><code> mController = new MediaController(this) {
 @Override
 public void hide() {

 if (mType != TYPE_AUDIO) super.hide();
 }

 @Override
 public boolean dispatchKeyEvent(KeyEvent event) {
 if(event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
 mController.hide();
 Activity a = (Activity)getContext();
 a.finish();
 return true;
 }
 return false;
 }
 };
</code></pre>

In MediaPlayer.onPrepared I added:

<pre><code>if (mType == TYPE_AUDIO) mController.show(0);
</code></pre>

This causes the controller to show at the start of audio playback, but not video playback.

The other phone control buttons continue to work as normal.

 super.setMediaPlayer(player);
 this.show(4000);

 //instead of press twice with press once "back" button to back

 Activity a = (Activity)getContext();
 a.finish();
 }
 return true;

 @Override

 this.setVisibility(View.GONE);

I am using mediacontroller in my app, but it shows only for 3 seconds. I have searched a lot, but in every document I see only the show function, set time out, but it has no effect. How can I always show mediacontroller?

I have tested <code>show(0)</code>, but it had no effect.

MediaController always show on Android

我在我的应用程序中使用了mediacontroller，但它只显示了3秒。我已经搜索了很多，但在每个文档中我只看到show函数，set time out，但它没有任何效果。我怎么才能总是显示媒体控制器呢？我测试过show(0)，但没有效果。
