hey everyone

so this is the code i am having at the moment. Basically what I want is to display 6 videos in a row, one after another. So I got up to this but now he tells me that vv2 (and every after) CAN NOT BE RESOLVED.

I am Javascript beginner so I have no idea what that means, only I think he doesn't have that variable set cause its defined in onCompletion function.

So how can I get vv2 out of the onCompletion?

Or is there any other possible way? Maybe some loop with $i++?

Answer 1

vv2 and the others cannot be resolved because you declared them locally inside the onCompletion methods. So yes, you should use a counter or something and then play the videos that way.

public class FullscreenActivity extends Activity {

    private int[] data = new int[]{R.raw.intro_video_part1, R.raw.intro_video_part2,
     R.raw.intro_video_part3, R.raw.intro_video_part4, R.raw.intro_video_part5, R.raw.intro_video_part6};

    int counter = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.activity_fullscreen);

    VideoView vv1 = (VideoView) findViewById(R.id.fullscreen_content);      
                vv1.setVideoPath("android.resource://" + getPackageName() + "/" + data[counter]);
                vv1.start();

            vv1.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                public void onCompletion(MediaPlayer mp) {
                    counter++;
                    vv1.setVideoPath("android.resource://" + getPackageName() + "/" + data[counter]);
                    vv1.start();
                }

            });
}
