我在我的应用程序中使用mediacontroller,但它只显示3秒钟。我搜索了很多,但在每个文档中我只看到show函数,设置超时,但它没有效果。我怎么能一直展示mediacontroller?
我测试了show(0)
,但没有效果。

您可以扩展MediaController类并以编程方式将其实例设置为VideoView类:
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);
}
}
以下是用法:
VideoView myVideoView = (VideoView) findViewById(R.id.my_video_view);
MediaController mc = new MyMediaController(myVideoView.getContext());
mc.setMediaPlayer(myVideoView);
myVideoView.setMediaController(mc);

您可以创建内联匿名类并覆盖某些方法。您需要覆盖hide方法并在那里不执行任何操作。您还需要覆盖dispatchKeyEvent方法以检查后退按键并调用super.hide()。否则在背面按下控制器不会隐藏,活动无法关闭。
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;
}
};

以这种方式尝试show方法:
new media controller().show(50000);
并检查http://developer.android.com/reference/android/widget/MediaController.html#show()。
SudeepSR:请注意,如果您调用show(0),它将显示媒体控制器,直到调用hide()。

你也可以创建一个内联的匿名类,并覆盖那里的hide方法,而不必为它创建一个全新的类:
mediaController = new MediaController(this) {
@Override
public void hide() {
//Do not hide.
}
};

您需要做的是,覆盖自定义控制器中的hide方法,不执行任何操作。
public class MyMediaController extends MediaController {
..
@Override
public void hide() {
// Do nothing here in order to always show
}
...
}
PS:我仍然需要点击视频来显示媒体控制器。

在尽力而为之后,以下代码对我有用!
mVideoView = (VideoView) findViewById(R.id.video);
mMediaController = new MediaController(this) {
//for not hiding
@Override
public void hide() {}
//for 'back' key action
@Override
public boolean dispatchKeyEvent(KeyEvent event) {
if(event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
Activity a = (Activity)getContext();
a.finish();
}
return true;
}
};
mMediaController.setAnchorView(mVideoView);
mMediaController.setMediaPlayer(mVideoView);
mVideoView.setMediaController(mMediaController);
mMediaController.requestFocus();
//only this showed the controller for me!!
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mVideoView.start();
mMediaController.show(900000000);
}
});
//finish after playing
mVideoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mediaPlayer) {
finish();
}
});

试试这个:
videoView.setOnCompletionListener(onVideoCompleted);
videoView.setOnPreparedListener(onVideoPrepared);
mc.setAnchorView(videoView);
mc.setMediaPlayer(videoView);
MediaController mc = new MediaController(this);
videoView.setMediaController(mc);
MediaPlayer.OnPreparedListener onVideoPrepared = new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mc.show(0);
}
};
MediaPlayer.OnCompletionListener onVideoCompleted = new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
mc.hide();
}
};

这可能是一个旧线程,但仍然没有答案,请尝试:
final MediaController mediaController = new MediaController(this);
mediaController.setAlwaysDrawnWithCacheEnabled(true);
mediaController.setAnchorView(vView);
mediaController.requestFocus();
vView.setOnPreparedListener( new OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mediaController.show( 0 );
}
});
vView.setVideoPath(Preview_Path);
vView.setMediaController(mediaController);
vView.start();
在MediaController Class" show"中发表评论。方法
**Use 0 to show
* the controller until hide() is called**
所以使用900000或更大的价值不会有帮助。 希望它可以帮助你。

我想淡化控制器的视频,并始终显示音频。这工作
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;
}
};
在MediaPlayer.onPrepared中,我添加了:
if (mType == TYPE_AUDIO) mController.show(0);
这会导致控制器在音频播放开始时显示,而不是视频播放。
其他手机控制按钮继续正常工作。

轻松!设置可见性" GONE"在事件中隐藏和设置可见性" VISIBLE"在秀!
MediaController mc= new MediaController(zoom.this){
@Override
public void setMediaPlayer(MediaPlayerControl player) {
super.setMediaPlayer(player);
this.show(4000);
}
@Override
public void show(int timeout) {
super.show(timeout);
this.setVisibility(View.VISIBLE);
}
//instead of press twice with press once "back" button to back
@Override
public boolean dispatchKeyEvent(KeyEvent event) {
if(event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
Activity a = (Activity)getContext();
a.finish();
}
return true;
}
@Override
public void hide() {
// TODO Auto-generated method stub
super.hide();
this.setVisibility(View.GONE);
//super.show(3000);
}
};
