Question

I am trying to replicate the experience found when you are uninstalling an app in ICS. Specifically the indeterminate progress indicator under the title bar. I have tried using requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS) and the various methods on Activity but to no avail. It instead shows a spinning progress bar in the top right hand corner of the screen/title bar. Am I missing something simple here? Or is this completely custom?

Here is the code I am using:

@Override
protected void onCreate(Bundle savedInstanceState) {
    requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
    super.onCreate(savedInstanceState);

    setProgressBarIndeterminate(true);
    setProgressBarIndeterminateVisibility(true);
}

You are using the ActionBar indeterminate progress bar, but you are looking for a ProgressBar View.

You can create the View programmatically or add it to a layout file like —

<ProgressBar
    android:id="@+id/progressBar1"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:indeterminate="true" />

Typically, you can decide when it is shown by calling .setVisibility(View.VISIBLE) to show and .setVisibility(View.GONE) when you are done.

If you have a minimum API of 11 and set your activity or app theme to @android:style/Theme.Holo you will get exactly that ProgressBar shown in your image.

If you want a similar effect on pre-API 11 devices, check out HoloEverywhere
