Remove black background on custom dialog

Question

I want to remove the black background on custom dialog as shown in the picture. I\'m sure the black background was from the dialog, not from app\'s background.

Answer 1

Sonehow getWindow().setBackgroundDrawable() didn't work for me with AlertDialog. I found an easier solution using Dialog. Here's my code -

        final Dialog dialog = new Dialog(this);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
        dialog.setContentView(R.layout.popup_window);
        dialog.show();

Answer 2

Use below two code lines. Tested as well.

getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)); getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);

Answer 3

Remove the background opacity color, you just need to set the DimAmount

dialog.getWindow().setDimAmount(float amount);

The new dim amount, from 0 for no dim to 1 for full dim.

Answer 4

Try this:

myDialog.getWindow().clearFlags(LayoutParams.FLAG_DIM_BEHIND);

Answer 5

I had the same problem with my custom dialog based on the Alertdialog.Builder, which had a black background showing in the title and the body when i use:

builder.setView(rootView)
  .setTitle(dialog_title)
  .setMessage(dialog_mesg)

solution was 1- Use one of the pre-defines alert dialog builder's themes:

• THEME_DEVICE_DEFAULT_DARK
• THEME_DEVICE_DEFAULT_LIGHT
• THEME_HOLO_DARK
• THEME_HOLO_LIGHT THEME_TRADITIONAL

THEME_DEVICE_DEFAULT_LIGHT worked best for me

2 - set the default dialog button (positive / negative) colors to which ever color you desire like so:

 Button b = mAlertDialog.getButton(AlertDialog.BUTTON_POSITIVE);
 Button d = mAlertDialog.getButton(AlertDialog.BUTTON_NEGATIVE);
 b.setTextColor(ContextCompat.getColor(getActivity(), R.color.primary));
 d.setTextColor(ContextCompat.getColor(getActivity(), R.color.primary));

Answer 6

After trying dozens of other solutions for this problem, what ended up working for me is:

<style name="translucentDialog" parent="android:Theme.Holo.Dialog">
    <item name="android:windowBackground">@android:color/transparent</item>
</style>

And then setting my dialog to use this theme.
