在android中填充自定义形状

谁能指导我如何填充这些封闭的形状。我已完成绘图部分。现在我想添加一个功能，如果用户绘制一个闭合的形状，它会自动填充。其次，如果用户稍后关闭了一个打开的形状，它也会被填充。我不知道要实现这一点需要寻找什么，因此需要指导。下面是示例图像。在这里，我想用绿色填充封闭的形状。用于绘图的代码为

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

    if(mBitmap!=null){
    canvas.drawBitmap(drawableBitmap, 0, 0, mBitmapPaint);
    System.out.println("NOTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT");

    canvas.drawPath( mPath,  mPaint);

    canvas.drawPath( circlePath,  circlePaint);}
    else
        System.out.println("I am nullllllllllllllllllllllllllllllllllllllllllllllllllllllll");
    }

    private float mX, mY;
    private static final float TOUCH_TOLERANCE = 4;

    private void touch_start(float x, float y) {
    mPath.reset();
    mPath.moveTo(x, y);
    mX = x;
    mY = y;
    }
    private void touch_move(float x, float y) {
    float dx = Math.abs(x - mX);
    float dy = Math.abs(y - mY);
    if (dx >= TOUCH_TOLERANCE || dy >= TOUCH_TOLERANCE) {
         mPath.quadTo(mX, mY, (x + mX)/2, (y + mY)/2);
        mX = x;
        mY = y;

        circlePath.reset();
        circlePath.addCircle(mX, mY, 30, Path.Direction.CW);
    }
    }
    private void touch_up() {


        mPath.lineTo(mX, mY);
    circlePath.reset();
    // commit the path to our offscreen
    if(mCanvas!=null)
    mCanvas.drawPath(mPath,  mPaint);

    else

        System.out.println("I AM MCANVASSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS");
    // kill this so we don't double draw
    mPath.reset();
    }

    @Override
    public boolean onTouch(View arg0, MotionEvent arg1) {
    float x = arg1.getX();
    float y = arg1.getY();

    switch (arg1.getAction()) {
        case MotionEvent.ACTION_DOWN:
            touch_start(x, y);
            invalidate();
            break;
        case MotionEvent.ACTION_MOVE:
            touch_move(x, y);
            invalidate();
            break;
        case MotionEvent.ACTION_UP:
            touch_up();
            invalidate();
            break;
    }
    return true;
    }

为了清晰起见，在这张图片中，您希望眼睛自动填充为完全黄色？他们到底是如何绘制形状的？代码会很有用。@javacoder16眼睛应该用绿色..Paint.setStyle（Paint.Style.FILL）填充。只有在形状完成后才使用该油漆。为了清晰起见，在这张图片中，您希望眼睛自动填充为完全黄色？他们到底是如何绘制形状的？代码会很有用。@javacoder16眼睛应该用绿色..Paint.setStyle（Paint.Style.FILL）填充。只有完成形状后才使用该油漆。
