您可以通过mVideoView.getDuration()获取视频的持续时间,最初将Progress栏设置为0,然后通过mVideoView.getCurrentPosition()获取视频的currentProgress.并根据当前视频的百分比(％)增加(当前* 100 /持续时间)的进度条状态.我尝试使用AsyncTask检出这个完整的例子.

main.xml中

android:layout_width="fill_parent"

android:layout_height="fill_parent"

>

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="@string/hello"

/>

style="@android:style/Widget.ProgressBar.Horizontal"

android:layout_width="fill_parent"

android:layout_height="10dp"

android:id="@+id/Progressbar"/>

VideoPlayActivity.java

public class VideoPlayActivity extends Activity {

ProgressBar mProgressBar;

VideoView mVideoView;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

String path = Environment.getExternalStorageDirectory().toString();

String filename = "/hr.3gp";

mProgressBar = (ProgressBar) findViewById(R.id.Progressbar);

mProgressBar.setProgress(0);

mProgressBar.setMax(100);

mVideoView = (VideoView) findViewById(R.id.my_Video_View);

mVideoView.setVideoURI(Uri.parse(path+filename));

new MyAsync().execute();

}

private class MyAsync extends AsyncTask

{

int duration = 0;

int current = 0;

@Override

protected Void doInBackground(Void... params) {

mVideoView.start();

mVideoView.setOnPreparedListener(new OnPreparedListener() {

public void onPrepared(MediaPlayer mp) {

duration = mVideoView.getDuration();

}

});

do {

current = mVideoView.getCurrentPosition();

System.out.println("duration - " + duration + " current- "

+ current);

try {

publishProgress((int) (current * 100 / duration));

if(mProgressBar.getProgress() >= 100){

break;

}

} catch (Exception e) {

}

} while (mProgressBar.getProgress() <= 100);

return null;

}

@Override

protected void onProgressUpdate(Integer... values) {

super.onProgressUpdate(values);

System.out.println(values[0]);

mProgressBar.setProgress(values[0]);

}

}

}
