android - 获取videoview下播放视频的进度时间？

Question

我需要获取“VideoView”中播放的视频的进度时间(即进度条左侧显示的时间)。

任何帮助将不胜感激。 谢谢。

Answer 1

您可以通过mVideoView.getDuration()获取视频的时长，初始设置进度条为0，然后通过mVideoView.getCurrentPosition()获取视频的currentProgress; 并根据当前视频的百分比 (%) 通过 (current * 100/duration) 增加进度条状态。我使用 AsyncTask 进行了尝试，查看这个完整的示例。

ma​​in.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]);
        }
    }
}
