#11223344 格式，11位表示透明度，为0时完全透明，为255时完全不透明，后三个分量依次表示R,G,B颜色参数。

//获取颜色字符串  得到 #ffffff格式字符串 
        // colorTest 为 #FF0000

        String c0=this.getResources().getString((int)R.color.colorTest);

//获取颜色数值，为8位数表示

        int c1 = this.getResources().getColor(R.color.colorTest);

        int c2 = Color.parseColor("#FF0000");

        int c3 = 0xFF0000;

        int c4 = 0xFFFF0000;

        int c5= Color.argb(255,255,0,0);

        Log.d("fff","Color 0 === "+c0);
        Log.d("fff","Color 1 === "+c1);
        Log.d("fff","Color 2 === "+c2);
        Log.d("fff","Color 3 === "+c3);
        Log.d("fff","Color 4 === "+c4);
        Log.d("fff","Color 5 === "+c5);
