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;
    }

}

ps起飛import com.dehvb.deheerenveenseboys.R; 從導入中，可能會導致一些問題。

如果您已經在布局文件中擁有了Webview而不是直接使用它！

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

將網址替換為您的網址，例如“ https://stackoverflow.com/ ”。 希望這對您有所幫助！

編輯：首先完全按照以下方式更新清單：

    <?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;
}
}

我已經測試過了，如果您願意，我可以發布屏幕截圖！
