Question

I am using AsyncTask to get data from a server and want to show a Screen while it is loading like this:

private class GetListTask extends AsyncTask {
    protected void onPreExecute() {
            Intent intent = new Intent();
                intent.setClass(Start.this, Wait.class);
                startActivity(intent);
    }

    protected Bitmap doInBackground(Object... args) {

//here i get the data from the server

        d = getImageFromURL(Start.valuesArray[Integer.parseInt(Value)][7]);
        Bitmap bitmap = ((BitmapDrawable) d).getBitmap();
        double ratio = (double) bitmap.getWidth() / (double) bitmap.getHeight();
        Bitmap scaled = Bitmap.createScaledBitmap(bitmap, width, (int) (width / ratio), true);
        return scaled;
    }

    protected void onPostExecute(Object objResult) {
        if (objResult != null && objResult instanceof Bitmap) {
            Bitmap result = (Bitmap) objResult;

            im.setImageBitmap(result);
        }
    }
}

Now, in onPostExecute() I need to hide this “Wait” Screen again, but how do I do that?
Thanks for helping!

Answer 1

instead of starting a different activity you can show your image in a PopupDialog and close it in onPostExecute
