机器人 - getResources（）和静态

问题描述

我有一个类

 公共类preferences扩展preferenceActivity实现OnShared preferenceChangeListener
 

出这个我尝试从另一个调用类中的方法。该方法包括：

  mFoo.setTextColor（getResources（）。的getColor（R.color.orange））
 

但它不工作。它告诉我 getResources 不是静态的...我怎样才能改变这种？

解决方案

This means you are trying to call getResources() from a static method, rather than a regular (instance) method. The easiest thing to do in your case, if mFoo is a TextView or some other widget, is to call getResources() on the Context available from the widget:

mFoo.setTextColor(mFoo.getContext().getResources().getColor(R.color.orange));

However, the fact that you are trying to reference a widget named mFoo from a static method scares the crap out of me. This is just asking for a memory leak. I think you really need to reconsider your use of static data members and methods.
