在画布上绘制两个相同图像的问题

Question

我在这里遇到一个问题，当我有 2 个痣时，它会崩溃，但如果只有一个，它就不会崩溃。

private int randX(){
    int x = (int) Math.round((Math.random()*CollierSurface.getWidth()));
    if (x<CollierSurface.getWidth()) randX();
    return x;
}

private int randY(){
    int y = (int) Math.round((Math.random()*CollierSurface.getHeight()));
    if (y<CollierSurface.getWidth()) randY();
    return y;
}

private void DrawMoles() {
    if (!_canDraw) return;
    try {
        CollierCanvas = CollierHolder.lockCanvas();
            Drawable background = getResources().getDrawable(R.drawable.collierabove);
            background.setBounds(0, 0, CollierSurface.getWidth(), CollierSurface.getHeight());
            background.draw(CollierCanvas);
            newMole(randX(), randY(), mole1);
            newMole(randX(), randY(), mole2);
    } catch (SurfaceHolder.BadSurfaceTypeException e) {

    } finally {
        if (CollierCanvas != null){
        CollierHolder.unlockCanvasAndPost(CollierCanvas);
        }
    }
}

private void newMole(int x, int y, Drawable mole){
    mole = getResources().getDrawable(R.drawable.mole);
    mole.mutate().setBounds((int)x-(mole.getIntrinsicWidth()), 
                        (int)y-(mole.getIntrinsicHeight()), 
                        (int)x+(mole.getIntrinsicWidth()), 
                        (int)y+(mole.getIntrinsicHeight()));
    mole.draw(CollierCanvas);
}

Answer 1

这是随机的 x 和 y 花费太长时间来制作

我现在要使用它

private int randX(){
    Random random = new Random();
    int x = random.nextInt(CollierSurface.getWidth());
    return x;
}

private int randY(){
    Random random = new Random();
    int y = random.nextInt(CollierSurface.getHeight());
    return y;
}
