Question

I want to create a Circluar Determinate ProgressBar, the kind which shows the Progress in the center of the Bar. Is there any default way to create this, or will i have to create my own custom one.

First add a progress_circle.xml to your res/drawable directory like this:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

<item android:drawable="@drawable/progress_circular_background"/>
<item>
    <shape
        android:innerRadiusRatio="3.4"
        android:shape="ring"
        android:thicknessRatio="6.0" >
        <gradient
            android:endColor="#ffffffff"
            android:startColor="#ffffff"
            android:type="sweep"
            android:useLevel="true" />
    </shape>
</item>
<item>
    <rotate
        android:drawable="@drawable/progress_particle"
        android:fromDegrees="0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toDegrees="360" />
</item>

</layer-list>

I Googled image searched both “progress_particle.png” and “progress_circular_background.png” (with quotes) since the android default drawables for those were missing. You’ll probably want to customize those but they’ll do to get you started.

Then in your xml layout:

<ProgressBar
    android:id="@+id/timer_progress"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="200dp"
    android:layout_height="200dp"
    android:indeterminate="false"
    android:max="60"
    android:progressDrawable="@drawable/progress_circle" />

My max is 60, since I’m using it for a seconds timer, but you might have something different.

The trick is that you need to use style=”?android:attr/progressBarStyleHorizontal” even though it’s a circular progress.
