Drawable 自定义颜##

如何得到一个Drawable?    举例：资源文件夹下：            this: 上下文            ResId：资源id R.drawable.c ==> 资源文件夹下的图片路径        Drawable drawable = this.getResources().getDrawable(ResId);        TextView textview = new TextView(this);        textview.setsetBackgroundDrawable(drawable);

    上面代码就是 为textview（Imageview）设置一个背景图片；    但我想自定义 图片背景颜色怎么办？

    这时就用到  **DrawableCompat** 这个类，它可以 上下兼容

Drawable wrapdrawable = DrawableCompat.wrap(drawable);
DrawableCompat.setTintList(wrapdrawable,ColorStateList.valueOf(Color.parseColor(piccolor)));

这样就可以随心所遇的为Drawable 着色了

设置背景绿色

下面是和 drawable 相关的工具类，有兴趣的小伙伴可以尝试下里面的方法
