github.com源码库 实现了加小红点，以及解决原来的drawableTop旋转 不能调节速度问题,卡顿问题

我这里的app:drawableTop支持旋转动画

这是效果图

顺便亮一亮我的代码堆栈

RadioGroup修改进行排斥,如何进行扩展兼容原来的RadioButton 其实 ,RadioButton和CheckBox的父类CompoundButton类有一个内部的选中监听类,
在调用setCheck的时候会回调2个监听

    if (mOnCheckedChangeListener != null) {
                mOnCheckedChangeListener.onCheckedChanged(this, mChecked);
            }
            if (mOnCheckedChangeWidgetListener != null) {
                mOnCheckedChangeWidgetListener.onCheckedChanged(this, mChecked);
            }

我这里mOnCheckedChangeWidgetListener是通过反射才能够实现兼容RadioButton的 这有啥办法,谁叫它私有化了,这让我怎么搞嘛。.

最后，还可以通过绘制添加小红点 继承RadioButton

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

        //获取到DrawableTop,  0 drawableleft 1 drawabletop 2 drawableright 3 drawablebottom
        Drawable drawable = getCompoundDrawables()[1];

        //获取到Drawable的left right top bottom的值
        Rect bounds = drawable.getBounds();

        //这里分析： 
        //getMeasuredWidth() / 2 等于整个控件的水平位置中心点
        //bounds.width() /2 drawable宽度的一半
        //radius / 2 小圆点宽度的一半
        //由于我们在布局文件中设置了Gravity为Center，所以最后小红点的x坐标为drawable图片右边对其+radius/2的位置上
        float cx = getMeasuredWidth() / 2 + bounds.width() / 2 - radius / 2;
        //y就比较好定义了，为drawable 1/4即可
        float cy = getPaddingTop() + bounds.height() / 4;

        //float cx, float cy, float radius, @NonNull Paint paint
        //把小红点绘制上去
        canvas.drawCircle(cx, cy, radius, paint);
    }
}

另外，我打算改一下我的RadioGroupX让它支持直接findById我发现有人非常好

具体是这篇文章了

我这里踩到的坑是兼容findbyid寻找index,兼容点击图片和点击文字都可以触发 兼容双击到顶,具体可以看我另外的一篇文章
