I am simply trying to create a spinning progress dialog. No text, no borders, no background. Just a spinning notification that lightly is center on the screen on top of content.

I have seen two different Stack Overflow questions in creating this custom Dialog.

They both use this styling:

   <style name="NewDialog" parent="@android:style/Theme.Dialog">

    <item name="android:windowFrame">@null</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowTitleStyle">@null</item>
    <item name="android:colorBackground">#ffffff</item>
    <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
    <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
    <item name="android:backgroundDimEnabled">true</item>
    <item name="android:width">600dip</item>
    <item name="android:height">100dip</item>
     <item name="android:textColor">#FF0000</item>

</style>

But in the Java side, one extends Dialog and contains lots of custom content, the other one is simply this:

public class MyProgressDialog extends ProgressDialog {

    public MyProgressDialog(Context context) {
        super(context, R.style.NewDialog);

    }

}

On the first (extends Dialog), I get a blank. No dialog. Nothing. On the code sample just above, I get a shrunken small dialog spinning inside a black box that is off centered.

Which method is more correct and can I have a sample on how to implement this?

Also, how can I make that dialog transparent/borderless?

    The ‘right way’ to do this now would be to extend DialogFragment http://developer.android.com/reference/android/app/DialogFragment.html

    If you are not using the compatibility library, you are not programming in the current Android world.

    If you want to extend Dialog, then I have some example code here: https://github.com/tom-dignan/nifty/tree/master/src/com/tomdignan/nifty/dialogs In this code, I implemented a kind of ‘progress dialog’ by extending Dialog. I extended Dialog because I wanted full control and wanted my Dialog to be full-screen.

    I would recommend reading the above DialogFragment doc and using that, though.

    So really, there is no right or wrong way here. Extending any of the three classes will work, but the cleanest and most current would be the DialogFragment approach.
