不确定样式进度－1

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

            android:toDegrees="1080" />
        <!-- 其中，toDegrees的值越大，转的圈圈越快 -->
    </item>
</layer-list>

不确定样式进度－2

<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"

    </shape>
</rotate>

确定样式进度

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:id="@android:id/background">
        <shape>
            <solid android:color="#f00" />

        </clip>
    </item>
</layer-list>

Activity

public class MainActivity extends Activity {
    ProgressBar pb, pb1;
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout);
        pb = (ProgressBar) findViewById(R.id.pb);
        pb1 = (ProgressBar) findViewById(R.id.pb1);
        
        pb1.setMax(pb.getMax());
        pb1.setProgress(pb.getProgress());
        pb1.setProgressTintList(pb.getProgressTintList());//进度条颜色
        pb1.incrementProgressBy(-5);//进度值增加
        
        pb1.setSecondaryProgress(pb.getSecondaryProgress());
        pb1.setSecondaryProgressTintList(pb.getSecondaryProgressTintList());
        pb1.incrementSecondaryProgressBy(5);//第二个进度条进度值增加
    }
