[英]Get the progress time of the video played under videoview?
我需要獲取在“ VideoView”中播放的視頻的進度時間(即進度欄中左側顯示的時間)。
任何幫助將不勝感激。 謝謝。
您可以通過mVideoView.getDuration()
獲取視頻的持續時間,將進度欄初始設置為0,然后通過mVideoView.getCurrentPosition();
獲取當前的視頻mVideoView.getCurrentPosition();
並根據百分比的當前視頻進度(% (current * 100 / duration)
增加進度條狀態。 我使用AsyncTask
檢驗了這個完整的示例,進行了嘗試。
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]);
}
}
}
您可以使用Thread來實現此目的,如下所示:
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();
}
});
我是這樣完成的
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);
}
如果您有任何疑問,請隨時提問
您可以使用getCurrentPosition()
和getDuration()
來計算進度。
