findViewById 无法构建 WebView

Question

public class FeedFragment extends Fragment {
private WebView livestream;


public FeedFragment() {
    // Required empty public constructor
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.fragment_feed, container, false);

    livestream = (WebView) WebView.findViewById(R.id.livestream);
    livestream.loadUrl("http://www.google.com");

}

为什么会出现以下错误：

error: non-static method findViewById(int) cannot be referenced from a static context where T is a type-variable: T extends View declared in method findViewById(int)

我厌倦了浪费时间阅读 android 文档并提出错误！

片段xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffb067"
tools:context=".FeedFragment">

<!-- TODO: Update blank fragment layout -->
<TextView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    android:gravity="center"
    android:textColor="@android:color/white"
    android:textSize="20sp"
    android:textStyle="bold"
    android:text="Feed Fragment" />

<WebView
    android:id="@+id/livestream"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</FrameLayout>

Answer 1

使用这个

 @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        livestream = (WebView) view.findViewById(R.id.livestream);
        livestream.loadUrl("http://www.google.com");
}

并从 onCreateView 中删除这些行：

livestream = (WebView) WebView.findViewById(R.id.livestream);
livestream.loadUrl("http://www.google.com");

Answer 2

尝试更改此直播 = (WebView) WebView.findViewById(...) 和 livestream = (WebView) findViewById(...)

Answer 3

要使 WebView 加载内联，请使用此代码感谢大家的帮助

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    livestream = (WebView) view.findViewById(R.id.livestream);
    livestream.setWebViewClient(new WebViewClient());
    livestream.loadUrl("http://www.google.com");
}
