Android以编程方式设置按钮背景
问题描述：
我想知道如何以编程方式设置按钮颜色? 我已经编写了以下代码，但失败了:
I would like to know how to set the button color programatically? I have coded the following but fails:
Button11.setBackgroundColor(R.color.red);
谢谢！
答
R.color.red是ID(也是int)，但不是颜色.
R.color.red is an ID (which is also an int), but is not a color.
改为使用以下之一:
// If you're in an activity:
Button11.setBackgroundColor(getResources().getColor(R.color.red));
// OR, if you're not:
Button11.setBackgroundColor(Button11.getContext().getResources().getColor(R.color.red));
或者，或者:
Button11.setBackgroundColor(Color.RED); // From android.graphics.Color
或者，要获得更多专业技能:
Or, for more pro skills:
Button11.setBackgroundColor(0xFFFF0000); // 0xAARRGGBB
