Question

I have downloaded a bunch of image from the internet with the following code:

for(int i = 1; i < 12; i++) {
    try {
        URL imageURL = new URL("http://domain/drawimage.php?type=" + i + "&d1=" + this.d1 + "&d2=" + this.d2);
        Bitmap image = BitmapFactory.decodeStream(imageURL.openConnection().getInputStream());

        bitmaps.add(image);
    } catch (Exception e) {
        System.out.println(e);
        e.printStackTrace();
    }
}

Later when I try to insert them into a LinearLayout (ll), the images won’t appear even though bitmaps.size() = 11.

for(int i = 0; i < bitmaps.size(); i++) {
    ImageView iv = new ImageView(c); // c = getApplicationContext()
    iv.setImageBitmap(bitmaps.get(i));
    iv.setVisibility(ImageView.VISIBLE);

    ll.addView(iv);
}

If I try with TextView, it works.

for(int i = 0; i < bitmaps.size(); i++) {
    TextView tv = new TextView(c); // c = getApplicationContext()
    tv.setText("image ");
    tv.setGravity(Gravity.CENTER_HORIZONTAL);

    ll.addView(tv);
}

Is the problem with the loading or does the insertation fail? How to fix?

Answer 1

I had problems printing out the picture on the PHP side. I should have checked that too. Now it’s working.
