使用VideoView和MediaController进行视频播放

一个视频播放的activity，可以直接拿过来用，比较简单，直接贴个[代码](http://www.xuebuyuan.com/ "代码")留作记录，效果如下：  ~~~ /** * 视频播放的activity<br> * 使用方法：<br> * 1、AndroidManifest.xml中添加此activity<br> * 2、Intent中存入待播放视频的URL，支持本地和网络<br> * 3、启动这个activity<br> * <br> * example：<br> * String url = "play url";<br> * Intent intent = new Intent();<br> * intent.setClass(this, VideoPlayActivity.class);<br> * intent.putExtra(VideoPlayActivity.KEY_URL, url);<br> * startActivity(intent);<br> * * @author ttworking * */ public class VideoPlayActivity extends Activity implements OnPreparedListener, OnErrorListener { public static final String KEY_URL = "view_url"; private static final String TAG = "VideoPlayActivity"; private static final int PLAY_RETURN = 2 * 1000; // 2 seconds private static final String KEY_PLAY_POSITON = "paly_position"; private static final String TOAST_ERROR_URL = "Paly url is null, please check parameter:" + KEY_URL; private static final String TOAST_ERROR_PLAY = "Paly error, please check url exist!"; private static final String DIALOG_TITILE = "奋力加载中，请稍后..."; private static String url; private ProgressDialog progressDialog; private MediaController mc; private VideoView videoView; private LinearLayout llMain; private LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); url = getIntent().getStringExtra(KEY_URL); if (url == null && savedInstanceState != null) { url = savedInstanceState.getString(KEY_URL); } if (url == null) { Toast.makeText(getApplicationContext(), TOAST_ERROR_URL, Toast.LENGTH_LONG).show(); finish(); return; } setTheme(android.R.style.Theme_NoTitleBar_Fullscreen); videoView = new VideoView(this); videoView.setVideoURI(Uri.parse(url)); videoView.requestFocus(); videoView.setOnPreparedListener(this); videoView.setOnErrorListener(this); mc = new MediaController(this); mc.setAnchorView(videoView); mc.setKeepScreenOn(true); videoView.setMediaController(mc); llMain = new LinearLayout(this); llMain.setGravity(Gravity.CENTER_VERTICAL); llMain.setOrientation(LinearLayout.VERTICAL); llMain.setLayoutParams(params); llMain.addView(videoView, params); setContentView(llMain); initDialog(); } @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); int palyPosition = videoView.getCurrentPosition(); if (palyPosition > PLAY_RETURN) { palyPosition -= PLAY_RETURN; } outState.putInt(KEY_PLAY_POSITON, palyPosition); outState.putString(KEY_URL, url); } @Override protected void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); videoView.seekTo(savedInstanceState.getInt(KEY_PLAY_POSITON)); } @Override public void onPrepared(MediaPlayer mp) { progressDialog.cancel(); videoView.start(); } @Override public boolean onError(MediaPlayer mp, int what, int extra) { Log.d(TAG, "onError:" + url); Toast.makeText(getApplicationContext(), TOAST_ERROR_PLAY + "\n" + url, Toast.LENGTH_LONG).show(); progressDialog.cancel(); finish(); return true; } private void initDialog() { progressDialog = new ProgressDialog(this); progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); progressDialog.setMessage(DIALOG_TITILE); progressDialog.setCancelable(false); progressDialog.show(); } } ~~~
