Android-在片段中显示WebView [英] Android - Displaying WebView in Fragment

问题描述

所以我在XML布局文件中有一个包含以下内容的片段:

So I have a fragment with the following in the XML layout file:

<RelativeLayout 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"
    tools:context="com.example.dwinnbrown.myapplicationv20.MainFragment">

    <!-- TODO: Update blank fragment layout -->
    <WebView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/webView"
        android:layout_alignParentTop="true"
        android:layout_alignParentStart="true"
        android:layout_alignParentBottom="true"
        android:layout_alignParentEnd="true" />

</RelativeLayout>

我现在正尝试通过与片段相关联的Java文件将网址加载到Web视图中.但是，我遇到了一个错误无法解析findViewByID(int)".有什么想法吗?

I am now trying to load a url into the web view through the java file associated with the fragment. However I am running into an error "cannot resolve findViewByID(int)". Any ideas?

这是我要用于该片段的代码:

Here is the code I am trying to use for the fragment:

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;


/**
 * A simple {@link Fragment} subclass.
 */
public class MainFragment extends Fragment {

    public MainFragment() {
        // 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_main, container, false);


        String url = "http://winn-brown.co.uk/";
        WebView view = (WebView) this.findViewById(R.id.webView);
        view.getSettings().setJavaScriptEnabled(true);
        view.loadUrl(url);
    }



}

推荐答案

做这样的事情

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

    View rootView = inflater.inflate(R.layout.fragment_main, container, false);

    String url = "http://winn-brown.co.uk/";
    WebView view = (WebView) rootView.findViewById(R.id.webView);
    view.getSettings().setJavaScriptEnabled(true);
    view.loadUrl(url);

    return rootView ;
}
