android mediaplayer 自定义 mediacontroller
以前做的一个项目，与流媒体相关的，那时学了好多相关知识，还写了一个自定义的 MediaPlayer Controller。现在稍微有点时间，简单整理一下，顺便分享出来。你要做的只是实现 Controller.ControlOper，并把 Controller 设置为你的 MediaPlayer 的控制器即可。注意那个mPlayer.setDataSource（）里面那个 url，是个开放的 rtsp 测试地址，可能会失效哦，如果失效的话，会看到“黑屏”，出现这种情况的话，请自己换个别的测试地址哦。
另外，在 onDestory() 里面要记得释放相关资源哦！
@Override
protected void onDestroy() {
super.onDestroy();
releaseMediaPlayer();
}
private void releaseMediaPlayer() {
mController.removeHandlerCallback();
if (mPlayer != null) {
mPlayer.stop();
mPlayer.release();
}
}
public void removeHandlerCallback() {
if(mHandler != null) {
mHandler.removeCallbacksAndMessages(null);
mHandler = null;
}
}
一、MediaplayerController
MediaplayerController（以下简称 Controller）是一个用于 MediaPlayer 的 view 类。该 view 上有通用的控件，如播放/暂停，前进/后退等。你需要做的只是实现 Controller.ControlOper 接口，并把该控制器设置为你的 MediaPlayer 的控制器即可。控制器的 view 都抽出来了，你可以根据需要进行修改，做出漂亮的控制器来了。
