How to resize an AlertDialog.Builder?

Question

I\'d like to resize my AlertDialog.Builder but I didn\'t find any resolution on this website, I tried everything I saw on questions like this one but seems olde

Answer 1

You should use custom dialog layout, check documentation.

Actually, you can resize dialog by getDialog().getWindow().setLayout(width, height); just call it onResume (not onCreateView).

Your view must be nested inside of a ScrollView, check post.

Reading huge amount of text in a Dialog can be annoying, it's better to use all pixels you have, consider simple Activity/Fragment.

Answer 2

If you're using an AlertDialog within a DialogFragment, with the AppCompat support library 23.2.1 or above, you must put the resize code in DialogFragment.onStart(), otherwise it will not work. Something like this:

@Override
public void onStart() {
    super.onStart();
    // Method 1
    alertDialog.getWindow().getAttributes().width = 400; // pixels
    alertDialog.getWindow().getAttributes().height = 500; // pixels
    // Re-apply the modified attributes
    alertDialog.getWindow().setAttributes(
           alertDialog.getWindow().getAttributes());

    // Method 2 (alternative)
    alertDialog.getWindow().setLayout(400, 500); // size in pixels
}
