Android 我不能在进度条上画圆边

我在程序中创建自定义进度。

但我不能创建半圆零件。我想创建类似进度的零件，这是在顶部框的图片中选择的

我的代码：

public class SemiCircleProgressBarView extends View {

    private Path mClippingPath;
    private float mPivotX;
    private float mPivotY;
    private Context context;

    private float progress = 0.0f;
    private float thickness;

    public SemiCircleProgressBarView(Context context) {
        super(context);
        this.context = context;
        initializeImage();
    }

    public SemiCircleProgressBarView(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.context = context;
        initializeImage();
    }

    private void initializeImage() {
        mClippingPath = new Path();
        mPivotX = 0;
        mPivotY = 0;
    }

    public void setClipping(float progress) {
        this.progress = progress;
        mClippingPath.reset();
        thickness = 0.25f * getHeight();
        mClippingPath.setFillType(Path.FillType.INVERSE_WINDING);
        mClippingPath.addCircle(0.5f * getWidth(), getHeight(), getHeight() - thickness, Path.Direction.CCW);
        invalidate();
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);

        float angle = (progress * 180) / 100;

        RectF oval = new RectF(mPivotX, mPivotY, mPivotX + getWidth(), mPivotY + 2.0f * getHeight());

        Paint p = new Paint();
        p.setColor(context.getResources().getColor(R.color.progress));

        Paint pbg = new Paint();
        pbg.setColor(context.getResources().getColor(R.color.progress_bg));

//        Paint cr = new Paint();
//        cr.setColor(Color.RED);

        canvas.clipPath(mClippingPath);
        canvas.drawArc(oval, 180, 360, true, pbg);
        canvas.drawArc(oval, 180, angle, true, p);
//        canvas.drawCircle(0.5f * thickness,getHeight(),30,cr);

        double radAngle = Math.toRadians(angle);
        float px = getWidth () - (float)Math.cos(radAngle) * ((float)getWidth() -  thickness);
        float py = getHeight() - (float)Math.sin(radAngle) * ((float)getHeight() - 0.5f * thickness);

        canvas.drawCircle(0.5f * px, py, 0.5f * thickness, p);
    }
}

底部选择矩形中的部分将在顶部选择矩形中同步进行

检查答案@ip696如果您愿意，请向上投票，…我需要在我的qestion中的图像上同步进行。半圆。一半。我认为您需要半旋转未满的循环进度，…使用油漆#设置行程上限（油漆。上限。圆形）作为@pskink pbg。设置行程上限（油漆。上限。圆形）；
