获取下videoview播放的视频进行时间？ [英] Get the progress time of the video played under videoview?

问题描述

我需要的是发挥VideoView（即在左边的进度条显示的时间）。

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).

任何帮助将真正成为AP preciated。  谢谢你。

Any help will really be appreciated. Thanks.

推荐答案

您可以通过获取视频的时长mVideoView.getDuration（），设置进度条0开始，然后得到的视频由的currentProgress mVideoView.getCurrentPosition（）; 和<$ C增加比例（％）基于视频的CurrentProgress进度条状态$ C>（当前* 100 /持续时间）。我尝试过了使用的AsyncTask 结帐这个完整的例子。

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.

的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]);
        }
    }
}
