状态更改时android更改视图的背景颜色

Question

how to use color state list for background? I know android:background="@drawable/drawable_selector" , but android:background="@color/color_selector" will cause exceptions. but android:background="#FFFFFF" works again, can anyone explains why?

now i want to change a layout's background color(not a drawable) when it's pressed, how to do it?

Answer 1

dynamically you can change like this. Use this if it is useful for you - textView.setBackgroundColor(Color.parseColor(getResources().getString(R.string.red)));

Answer 2

将颜色放入res / values / colors.xml中，例如#FFFFFF，然后在drawable目录中创建一个drawable xml，没关系。
