Why does the following code failed? I just want switch between
different files. But the application crashed again and again
package com.google.android.samples.media.test;
import android.app.Activity;
import android.graphics.PixelFormat;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.MediaController;
import android.widget.VideoView;
public class VideoViewDemo extends Activity {
/** Called when the activity is first created. */
private String path = "/data/room.mp4";
private VideoView mVideoView;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
getWindow().setFormat(PixelFormat.TRANSLUCENT);
setContentView(R.layout.videoview);
mVideoView = (VideoView) findViewById(R.id.surface_view);
MediaController nc = new MediaController(this);
mVideoView.setMediaController(nc);
mVideoView.requestFocus();
Button b1 = (Button)findViewById(R.id.button1);
Button b2 = (Button)findViewById(R.id.button2);
b1.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View view) {
// TODO Auto-generated method stub
mVideoView.pause();
mVideoView.stopPlayback();
mVideoView.setVideoPath("XXXXPATH1.MP4");
}
});
b2.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View view) {
// TODO Auto-generated method stub
mVideoView.pause();
mVideoView.stopPlayback();
mVideoView.setVideoPath("XXXXPATH2.MP4");
}
});
}
}
