            webSettings.setJavaScriptEnabled(true);
            // Force links and redirects to open in the WebView instead of in a browser
            the_verge.setWebViewClient(new WebViewClient());
            the_verge.loadUrl("http://www.theverge.com");

        @Override

    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".TheVerge">

    <TextView android:text="" android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

AndroidManfest xml

        </activity>
    </application>

您需要将 WebView 添加到布局文件中。将其更改为类似这样的内容

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"
android:id="@+id/activity_the_verge_webview"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".TheVerge">

<WebView
    android:id="@+id/webView1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentStart="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true" />

然后将您的 onCreate() 方法替换为这个方法

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_the_verge);

         the_verge = (WebView) findViewById(webView1);
        // Enable Javascript
        WebSettings webSettings = the_verge.getSettings();
        webSettings.setJavaScriptEnabled(true);
        // Force links and redirects to open in the WebView instead of in a browser
        the_verge.setWebViewClient(new WebViewClient());
        the_verge.loadUrl("http://www.theverge.com");
    }
