findViewById在片段 [英] findViewById in Fragment

问题描述

我想创建一个片段，将参照我的XML中的片段所创建的ImageView的元素的ImageView的。但是， findViewById 方法只能如果我向一个Activity类。反正是有它的，我可以在片段使用它呢？

I am trying to create an ImageView in a Fragment which will refer to the ImageView element which I have created in the XML for the Fragment. However, the findViewById method only works if I extend an Activity class. Is there anyway of which I can use it in Fragment as well?

public class TestClass extends Fragment {
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        ImageView imageView = (ImageView)findViewById(R.id.my_image);
        return inflater.inflate(R.layout.testclassfragment, container, false);
    }
}

在 findViewById 方法上有一个错误，指出该方法是不确定的。

The findViewById method has an error on it which states that the method is undefined.

推荐答案

使用 getView（）。这将返回根视图的片段，这个你可以叫 findViewById（）。

Use getView(). This will return the root view for the fragment, with this you can call findViewById().

ImageView imageView = (ImageView) getView().findViewById(R.id.foo);
