How to implement a material design circular progress bar in android

<ProgressBarandroid:id="@+id/loading_spinner"android:layout_width="wrap_content"android:layout_height="wrap_content"android:indeterminateTintMode="src_atop"android:indeterminateTint="@color/your_customized_color"android:layout_gravity="center" />

The effect looks like this:

Nice implementation for material design circular progress bar (from rahatarmanahmed/CircularProgressView),

<com.github.rahatarmanahmed.cpv.CircularProgressView    xmlns:app="http://schemas.android.com/apk/res-auto"    android:id="@+id/progress_view"    android:layout_width="40dp"    android:layout_height="40dp"    app:cpv_indeterminate="true"/>

I've backported the three Material Design progress drawables to Android 4.0, which can be used as a drop-in replacement for regular ProgressBar, with exactly the same appearance.

These drawables also backported the tinting APIs (and RTL support), and uses ?colorControlActivated as the default tint. A MaterialProgressBar widget which extends ProgressBar has also been introduced for convenience.
