android 使用colors.xml设置颜色
设置Button(btn)背景色:
color.xml如下:
<?xml version="1.0" encoding="utf-8"?> <resources> <drawablename="red">#f00</drawable> <drawablename="green">#0f0</drawable> <drawablename="gray">#ccc</drawable> </resources>
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);
