Android进度条填写

Question

I want a loading bar in a circle shape. I want to fill it with an integer i tried this

 <ProgressBar
        android:id="@+id/progressBar"
        style="?android:attr/progressBarStyleLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"

        android:indeterminateDrawable="@xml/progress" >
    </ProgressBar>

progress.xml:

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="360" >

<shape
    android:innerRadiusRatio="3"
    android:shape="ring"
    android:thicknessRatio="8"
    android:useLevel="false" >
    <size
        android:height="48dip"
        android:width="48dip" />

    <gradient

        android:centerY="0.50"
        android:endColor="#000000"
        android:startColor="#ffffff"
        android:gradientRadius="20"
        android:type="radial"
        android:useLevel="false" />
</shape>

and in my activity

    protected void onPostExecute(Void result) {

            bar.setProgress(50);
            bar.setMax(100);
            bar.setVisibility(View.VISIBLE);
    }

The Circle stays black. If i set the gradient type to sweep, the circle fills with startcolor black and endcolor white.. and it constantly repeats.

But I want the circle to be filled once.. so it starts black and fills white; only 1 time..

Is this possible?
