获取在videoview下播放的视频的进度时间？

Question

I need to get the progress time of the video that is played in "VideoView"(ie the time shown in the left hand side in progress bar).

Any help will really be appreciated. Thanks.

Answer 1

You can get the Duration of the Video by mVideoView.getDuration() , set the Progress bar to 0 initially and then get the currentProgress of Video by mVideoView.getCurrentPosition(); and increase the Progress Bar status based on the CurrentProgress of Video in Percentage(%) by (current * 100 / duration) . I tried it out using AsyncTask checkout this complete Example.

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<VideoView  android:id="@+id/my_Video_View"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />

    <ProgressBar android:layout_alignParentBottom="true"
  style="@android:style/Widget.ProgressBar.Horizontal"
  android:layout_width="fill_parent"
  android:layout_height="10dp"
  android:id="@+id/Progressbar"/>
</RelativeLayout>

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<Void, Integer, Void>
    {
        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]);
        }
    }
}

You can use Thread for this purpose like below:

videoView.start();
    videoView.setOnPreparedListener(new OnPreparedListener() {
        public void onPrepared(MediaPlayer mp) {
            running = true;
            final int duration = videoView.getDuration();

            new Thread(new Runnable() {
                public void run() {  
                    do{                         
                        textView.post(new Runnable() {
                         public void run() {
                            int time = (duration - videoView.getCurrentPosition())/1000;
                            textView.setText(time+"");
                         }
                        });
                        try {
                            Thread.sleep(500);
                        } catch (InterruptedException e) {                                      
                            e.printStackTrace();
                        }
                        if(!running) break;
                    }
                    while(videoView.getCurrentPosition()<duration);
                }
            }).start();                     
        }
    });

I accomplished it such way

private void playVideo() {
    setViewNotVisibility();

    final String videoSource = "android.resource://" + getPackageName() + File.separator + R.raw.moviiegood;
    videoView.setKeepScreenOn(true);
    videoView.setVideoURI(Uri.parse(videoSource));
    videoView.setMediaController(null);
    videoView.setOnCompletionListener(myVideoViewCompletionListener);
    videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                                        @Override
                                        public void onPrepared(MediaPlayer mp) {
                                            startVideo();
                                            setDuration();
                                            timerCounter();
                                        }
                                    }

    );
}

private Timer timer;
private void timerCounter(){
    timer = new Timer();
    TimerTask task = new TimerTask() {
        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    updateUI();
                }
            });
        }
    };
    timer.schedule(task, 0, 1000);
}

private int duration = 0;

private void setDuration(){
    duration = videoView.getDuration();
}

private void updateUI(){
    if (pbVideoView.getProgress() >= 100) {
        timer.cancel();
    }
    int current = videoView.getCurrentPosition();
    int progress = current * 100 / duration;
    pbVideoView.setProgress(progress);
}

您可以使用getCurrentPosition()和getDuration()来计算进度。
