我想利用MediaPlayer
類播放視頻文件。問題是視頻沒有得到顯示,儘管我可以聽到視頻播放中的聲音。使用MediaPlayer類播放視頻
以下是活動
public class MainActivity extends Activity implements OnClickListener {
private SurfaceView surfaceView;
private Button btnPlay;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
addListener();
}
private void init() {
// TODO Auto-generated method stub
surfaceView = (SurfaceView) findViewById(R.id.surfaceView1);
btnPlay = (Button) findViewById(R.id.btnPlay);
}
private void addListener() {
// TODO Auto-generated method stub
btnPlay.setOnClickListener(this);
}
MediaPlayer mediaPlayer = null;
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.btnPlay:
try{
if (mediaPlayer != null) {
mediaPlayer.reset();
mediaPlayer.release();
}else{
getWindow().setFormat(PixelFormat.UNKNOWN);
MediaPlayer mediaPlayer = MediaPlayer.create(this, R.raw.wildlife);
SurfaceHolder surfaceHolder = surfaceView.getHolder();
surfaceHolder.setFixedSize(176, 144);
surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
mediaPlayer.setDisplay(surfaceHolder);
mediaPlayer.start();}
}catch (Exception e) {
Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}
break;
default:
break;
}
}
}
下面的代碼是佈局的XML代碼
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<SurfaceView
android:id="@+id/surfaceView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true" />
<Button
android:id="@+id/btnPlay"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignRight="@+id/surfaceView1"
android:layout_alignTop="@+id/surfaceView1"
android:text="@string/play" />
</RelativeLayout>
請告訴我需要做什麼? 在此先感謝。
您可以創建自己的曲面視圖並在您的活動中調用此曲面視圖來播放視頻。希望這可以解決您的問題 – AndroidOptimist 2013-12-07 06:42:11
