错误:无法从静态上下文中引用非静态方法“findViewById(int)" [英] Error: Non-static method 'findViewById(int)' cannot be referenced from a static context

问题描述

我正在使用 Android Studio(测试版)，在onCreateView()"中使用此 java 代码时，出现错误.

I am using Android Studio (Beta), and while using this java code in 'onCreateView()', I get an error.

ListView listView = (ListView) findViewById(R.id.someListView);

这是错误:

Non-static method 'findViewById(int)' cannot be referenced from a static context

我该如何解决这个问题?

How do I fix this?

推荐答案

假设您在一个活动中有一个静态片段内部类:您正在尝试调用该活动的 findViewById() 而您不能在不包含对父级的引用的静态内部类中.

Assuming you have a static fragment inner class inside an activity: you're trying to call the activity's findViewById() which you cannot in a static inner class that doesn't hold a reference to the parent.

在 onCreateView() 中，您需要在刚刚膨胀的根视图上调用它，例如

In onCreateView() you need to call it on the root view you just inflated, e.g.

 ListView listView = (ListView) rootView.findViewById(R.id.someListView);
