android如何在一个videoview中播放不同的视频
android如何在一个videoview中播放不同的视频
提问于 2014-03-25 17:26:38
我有这个代码，其中我将播放不同的视频使用一个视频视图只…
但由于我是android编程的新手，我不知道如何正确使用setoncompletionlistener。你介意帮我解决我的问题吗？
这是我的代码..
感谢您的帮助：)
package com.thesis.americansignlanguage;
import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.widget.MediaController;
import android.widget.TextView;
import android.widget.VideoView;
public class Videocompareclass extends Activity implements MediaPlayer.OnCompletionListener {
String get;
VideoView view;
int wordIndex = 0;
String[] getSplit;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.gesturecompare);
Bundle gotWord = getIntent().getExtras();
get = gotWord.getString("key");
TextView Word = (TextView)findViewById(R.id.textView1);
view = (VideoView)findViewById(R.id.vd_view);
Word.setText(get);
view.setMediaController(new MediaController(this));
getSplit = get.split(" ");
String path = "/storage/sdcard1/video/" + getSplit[wordIndex] + ".mp4";
wordIndex++;
view.setVideoPath(path);
view.requestFocus();
view.start();
view.setOnPreparedListener(new OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
// progressBar.setVisibility(View.GONE);
// loadingText.setVisibility(View.GONE);
}
});
view.setOnErrorListener(new OnErrorListener() {
@Override
public boolean onError(MediaPlayer mp, int what, int extra) {
Log.d("error code", "whate: " + what +" extra"+extra);
//progressBar.setVisibility(View.GONE);
//loadingText.setVisibility(View.GONE);
return false;
}
});
view.setOnCompletionListener(completeListener);
}
OnCompletionListener completeListener = new OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
Log.e("VideoPlayer", "OnComplete");
if(get.length() >= wordIndex) {
String path = "/storage/sdcard1/video/" + getSplit[wordIndex] + ".mp4";
wordIndex++;
view.setVideoPath(path);
view.requestFocus();
view.setOnCompletionListener(completeListener);
view.start();
}
else {
mp.release();
finish();
}
}
};
}这是logcat所说的..它有像ArrayIndexOutofBounds这样的错误..我不知道如何修复它..
