how to create Image slideshow for android? [closed]

It's difficult to tell what is being asked here. 开发者_如何学GoThis question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 11 years ago.

I want to develop a image slideshow or animation like Gif animation for android. 3 or 4 images will be there and each image will display alternately.


I would use a ViewFlipper and create a thread that sleeps for the delay you want between frames, then shows the next image.

public class YourFlipperActivity extends Activity {

protected void yourFlipperForward() {
    // Set animation
    tflipper.setAnimation(AnimationUtils.loadAnimation(
            YourFlipperActivity.this, R.anim.slide_in));

    // Show next step
    tflipper.showNext();

}

protected void yourFlipperBack() {
    // Set animation
    tflipper.setAnimation(AnimationUtils.loadAnimation(
            YourFlipperActivity.this, android.R.anim.slide_in_left));

    // Show next step
    tflipper.showPrevious();

}

private ViewFlipper tflipper;

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

    setContentView(R.layout.your_layout);

    tflipper = (ViewFlipper) findViewById(R.id.your_flipperid);
}

public void close(View v) {
    finish();
}

public void flipNext(View v) {
    yourFlipperForward();
}

public void flipPrevious(View v) {
    yourFlipperBack();
}
}

Next, you'll want to create an aSync task that loops your flipNext method.

Something like:

private class YourPollTask extends AsyncTask<Integer, Void, Integer> {
    /**
     * The system calls this to perform work in a worker thread and delivers
     * it the parameters given to AsyncTask.execute()
     */
    protected Integer doInBackground(Integer... millis) {
        try {
            int waited = 0;
            int duration = millis[0].intValue();
            while (waited < duration) {
                Thread.sleep(1000);
                waited += 1000;
                flipNext();
                }
            }
        } catch (InterruptedException e) {
            // do nothing
        }

        return 1;
    }

Good luck with that.

Alternately, if you want to use an actual animated gif, you could use GifSplitter, which is free. I don't recommend using animated gifs, though, because they are pretty old-school.


Please take a look at Android APIDemo.
