如何初始化容器（ViewGroup中）？ [英] How to initialize Container(ViewGroup)?

问题描述

自动在OnCreateView，有：

Automatically, in OnCreateView, there's:

  @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

我想我的变量初始化为像OnCreateView中的AsyncTask相同的方式。
我能够初始化这些变量：

I want to initialize my variable as in the same way like OnCreateView in AsyncTask. I was able to initialize these variable :

LayoutInflater inflater;
            ViewGroup container;
            inflater = (LayoutInflater) ctx
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View rootView = inflater.inflate(R.layout.fragment_pager_list,
                    container, false);

不过，我得到该容器未初始化错误！所以，我怎么能初始化呢？谢谢

However, i get the error that container isn't initialized! so how can i initialize it? Thanks

推荐答案

它的抱怨，因为你还没有的初始化的变量的值容器 - 你只有的声明的它。初始化意味着你为它分配一个值，如的ViewGroup容器= NULL;

It's complaining because you have not initialized the value of the variable container - you have only declared it. Initialization means you assign it a value, such as ViewGroup container = null;.

你的目的，你可以省略完全和简单地传递null来调用膨胀。

For your purposes, you can omit that entirely and simply pass null to the call to inflate.

LayoutInflater inflater = (LayoutInflater) ctx.
    getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rootView = inflater.inflate(R.layout.fragment_pager_list, null);
