当进度条在android中旋转时如何停止更改方向

ProgressBar progressBar = findViewById(R.id.progressBar);
progressBar.setIndeterminate(false);
progressBar.setProgress(50);

public class CustomProgressBar extends ProgressBar {

    public CustomProgressBar(Context context) {
        super(context);
    }

    public CustomProgressBar(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomProgressBar(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected synchronized void onDraw(Canvas canvas) {
        // 在这里控制旋转方向
        super.onDraw(canvas);
    }
}

<com.example.CustomProgressBar
    android:id="@+id/progressBar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:indeterminate="true" />
