设置Button(btn)背景色:

color.xml如下:
复制代码
 <?xml version="1.0" encoding="utf-8"?>   <resources>       <drawablename="red">#ff00ff00</drawable>       <drawablename="green">#0f0</drawable>       <drawablename="gray">#ccc</drawable>   </resources>  
复制代码

方法一:

1 btn.setBackgroundColor(getResources().getColor(R.color.green));

 方法二:

Resources resources =YourActivity.this.getResources();  Drawable drawable = resources.getDrawable(R.color.green);btn.setBackgroundDrawable(drawable);
