本文实例讲述了Android编程视频播放api之MediaPlayer用法。分享给大家供大家参考，具体如下：

现在项目要做音视频这块功能，这正是我相对比较薄弱的地方，项目中要用到，赶紧抓紧时间学习。前面有一编介绍不错的文章https://www.jb51.net/article/121881.htm，值得学习。

这里给出一个较为简单的示例：

public class MediaPlayerActivity extends Activity implements OnClickListener {  private Button mlocalvideo;  private Button mstreamvideo;  private Button mlocalaudio;  private Button mresourcesaudio;  private static final String MEDIA = "media";  private static final int LOCAL_AUDIO = 1;  private static final int RESOURCES_AUDIO = 3;  private static final int STREAM_VIDEO = 5;  @Override  protected void onCreate(Bundle icicle) {    super.onCreate(icicle);    setContentView(R.layout.activity_mediaplayer);    initViewsAndEvents();  }  private void initViewsAndEvents() {    mlocalaudio = (Button) findViewById(R.id.localaudio);    mresourcesaudio = (Button) findViewById(R.id.resourcesaudio);    mlocalvideo = (Button) findViewById(R.id.localvideo);    mstreamvideo = (Button) findViewById(R.id.streamvideo);    mlocalaudio.setOnClickListener(this);    mresourcesaudio.setOnClickListener(this);    mlocalvideo.setOnClickListener(this);    mstreamvideo.setOnClickListener(this);  }  @Override  public void onClick(View v) {    switch (v.getId()) {    case R.id.localaudio:    case R.id.localvideo:      Intent intent = new Intent(MediaPlayerActivity.this.getApplication(),          MediaPlayerDemo_Audio.class);      intent.putExtra(MEDIA, LOCAL_AUDIO);      startActivity(intent);      break;    case R.id.resourcesaudio:      Intent resIn = new Intent(MediaPlayerActivity.this.getApplication(),          MediaPlayerDemo_Audio.class);      resIn.putExtra(MEDIA, RESOURCES_AUDIO);      startActivity(resIn);      break;    case R.id.streamvideo:      Intent streamIn = new Intent(MediaPlayerActivity.this,          MediaPlayerDemo_Video.class);      streamIn.putExtra(MEDIA, STREAM_VIDEO);      startActivity(streamIn);      break;    }  }}
