java - Android PorterDuff.Mode error: PorterDuff cannot be resolved to a variable

Question

I've got a class which extends LinearLayout, can't figure out how to get PorterDuff.Mode working with this piece of code:

this.getBackground().setColorFilter(Color.parseColor("#a7d2e3"), PorterDuff.Mode.DARKEN);

"PorterDuff cannot be resolved to a variable"

I've imported porterduff and from what I can see PorterDuff is a static class. Any ideas?

Answer 1

将此添加到您的导入中，因为出于某种原因，Eclipse 不会自动为此执行此操作：

import android.graphics.PorterDuff;

Answer 2

仅使用Mode.DARKEN，然后导入android.graphics.PorterDuff.Mode;
