自己写了一个，供参考

   @Override
    protected void onDraw(Canvas canvas) {
        Drawable[] drawables = getCompoundDrawables();
        if (drawables != null) {
            Drawable drawableTop = drawables[1];
            if (drawableTop != null) {
                float textHeight=measureHeight(getText().toString());
                int drawablePadding = getCompoundDrawablePadding();
                int drawableHeight = drawableTop.getIntrinsicHeight();
                float bodyHeight = textHeight + drawableHeight + drawablePadding;
                setPadding(0, (int)(getHeight() - bodyHeight), 0, 0);
                canvas.translate(0, 0-(getHeight() - bodyHeight) / 2);
            }
        }
        super.onDraw(canvas);
    }

    //获取文本高度
    public int measureHeight(String text) {
//        Rect result = new Rect();
//        // Measure the text rectangle to get the height
//        getPaint().getTextBounds(text, 0, text.length(), result);
//        return  result.height();
        Paint.FontMetrics fontMetrics= getPaint().getFontMetrics();

        return (int)(fontMetrics.descent-fontMetrics.ascent+ fontMetrics.leading);
    }

<cn.vko.teacher.base.MyRadioButton style="@style/leftMunuPrperty" android:layout_marginTop="29.44dp" android:clickable="true" android:drawablePadding="-45dp" myradio:drawableSize="30dp" android:text="aaaaaa" android:gravity="center" myradio:drawableTop="@drawable/iconfont_kecheng"/> 就这。。。里面啥也没设置, 用自定义的原因是我对图片进行了处理边界缩小了。其他的什么都没干
