我怎样才能在这里添加一个网页视图？

Question

我应该怎么做我的脚本，我已经尝试了一切，但没有任何工作..他给 webview 一个错误？

package com.dehvb.dehvbapp;

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.WebSettings;
import android.webkit.WebView;


public class ProgrammaFragment extends Fragment {

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

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

        WebView myWebView = (WebView) findViewById(R.id.webview);
        WebSettings webSettings = myWebView.getSettings();
        webSettings.setJavaScriptEnabled(true);
        myWebView.loadUrl("http://www.example.com");

        return rootView;
    }

}

Answer 1

public class ProgrammaFragment extends Fragment {
    Webview wv;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.fragment_programma, container, false);
        wv = (WebView) rootView.findViewById(R.id.yourWebviewId);

        //Use the thread policy only if your load URL doesn't work on main thread.
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);

        wv.loadUrl("http://www.example.com");

        return rootView;
    }

}

附：从导入中删除import com.dehvb.deheerenveenseboys.R;，这可能会导致一些问题。

Answer 2

如果您的布局文件中已经有 webview，则直接使用！

WebView wb = (WebView)rootView.findViewById(R.id.webView);
wb.loadUrl(url);

将 url 替换为您的网址，例如“https://stackoverflow.com/”。 希望这有帮助！

编辑： 首先像这样更新您的清单：

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.dehvb.dehvbapp"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="17" />

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.dehvb.dehvbapp.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

和你的 ProgrammaFragment.class

public class ProgrammaFragment extends Fragment
{
WebView wv;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{

    View rootView = inflater.inflate(R.layout.fragment_programma, container, false);
    wv = (WebView) rootView.findViewById(R.id.WebView1);

    //Use the thread policy only if your load URL doesn't work on main thread.
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);

    wv.loadUrl("https://stackoverflow.com/");

    return rootView;
}
}

我已经测试过了，如果你愿意，我可以发截图！
