Question

这样做的目的是让一个网页在中触发应用程序本身。该应用程序运行没有故障，但从未见过该网页。 .xml包含网页及其下方的列表。

.xml文件读为

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_centerVertical="true" android:layout_width="match_parent" android:layout_height="match_parent"> <WebView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/webview" android:layout_width="fill_parent" android:layout_height="fill_parent" /> <ListView android:layout_width="fill_parent" android:layout_height="500dp" android:id="@android:id/list"/> </LinearLayout>

.java中的活动读为

@Override protected void onCreate(final Bundle savedInstanceState) { super.onCreate(savedInstanceState); WebView myWebView = new WebView(this); myWebView.getSettings().setJavaScriptEnabled(true); myWebView.setWebViewClient(new WebViewClient()); myWebView.loadUrl("https://google.com"); // Other AWS gibberish }

我可以将网页作为单独的应用程序启动，但这不是我想要的。

WebView webview = new WebView(this); setContentView(webview); webview.getSettings().setJavaScriptEnabled(true); webview.loadUrl("http://google.ca");

编辑：我已经在清单中添加了互联网权限

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

我使用here，here，here和documentation的一些参考资料未成功

编辑2：浏览设备调试文件并记录以下内容

而不是在onCreate实例化新的Webview，我认为您可能需要使用布局中指定的那个：

@Override
protected void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.NAME_OF_THE_XML_FILE); // change here to match the name of your xml file


    // WebView myWebView = new WebView(this); instead of this, try this one below:
    WebView myWebView = (WebView) findViewById(R.id.webview);

    myWebView.getSettings().setJavaScriptEnabled(true);
    myWebView.setWebViewClient(new WebViewClient());
    myWebView.loadUrl("https://google.com");

    // Other AWS gibberish
}

应用程序中的Android webview未加载
