How to create a horizontal loading progress bar?

Question

When uninstalling an android application, or do some configuration, there will show such a horizontal progress bar, like following picture:

It's not the same style like @android:style/Widget.ProgressBar.Horizontal.

How to use it in my own application?

Answer 1

Just add a STYLE line and your progress becomes horizontal:

<ProgressBar         style="?android:attr/progressBarStyleHorizontal"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:id="@+id/progress"         android:layout_centerHorizontal="true"               android:layout_centerVertical="true"               android:max="100"          android:progress="45"/> 

Answer 2

It is Widget.ProgressBar.Horizontal on my phone, if I set android:indeterminate="true"
