MediaController始终在Android上显示

问题描述

我在我的应用程序中使用mediacontroller，但仅显示3秒钟.我进行了很多搜索，但是在每个文档中，我仅看到show函数，设置了超时时间，但没有任何效果.如何始终显示mediacontroller?

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?

我已经测试过show(0)，但是没有效果.

I have tested show(0), but it had no effect.

推荐答案

您可以扩展MediaController类，并以编程方式将其实例设置为VideoView类:

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

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);
    }

}

用法:

VideoView myVideoView = (VideoView) findViewById(R.id.my_video_view);
MediaController mc = new MyMediaController(myVideoView.getContext());
mc.setMediaPlayer(myVideoView);
myVideoView.setMediaController(mc);
