Dialog with transparent background in Android

Question

How do I remove the black background from a dialog box in Android. The pic shows the problem.

Answer 1

Attention : Don't use builder for changing background.

Dialog dialog = new Dialog.Builder(MainActivity.this)
                                .setView(view)
                                .create();
dialog.show();dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);

change to

Dialog dialog = new Dialog(getActivity());
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(view);
dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
dialog.show();

When using Dialog.builder, it's not giving getWindow() option in it.
