我正在尝试将 Web 视图加载到对话框中.我正在使用以下代码.

I am trying to load web view in to dialog. I am usuing the following code.

            .findViewById(R.id.my_ac_my_service_timewarnercable_link);

            wb.getSettings().setJavaScriptEnabled(true);
            wb.loadUrl("http://www.google.com");
            wb.setWebViewClient(new HelloWebViewClient());
            dialog.setCancelable(true);

推荐答案

使用包含 Web 视图的 XML 布局.然后调用 dialog.setContentView(R.layout.web_dialog)

Use a XML layout containing a Webview. Then call dialog.setContentView(R.layout.web_dialog)

之后像这样设置webview:WebView wv = (WebView) findViewById(R.id.webview);R.id.webview"是 XML 布局文件中的 ID.

Set up the webview afterwards like so: WebView wv = (WebView) findViewById(R.id.webview); "R.id.webview" being the ID in the XML Layout file.

对话框布局示例:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
>
    <WebView
        android:id="@+id/webview"
        android:scrollbars="vertical"
        android:scrollbarAlwaysDrawVerticalTrack="true"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true" />
</LinearLayout>

您的代码已修改:

final TextView seeMonthlyBill = (TextView) parentLayout
            .findViewById(R.id.my_ac_my_service_timewarnercable_link);
    seeMonthlyBill.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            Dialog dialog = new Dialog(getActivity());
            dialog.setContentView(R.layout.web_dialog)
            WebView wb = (WebView) dialog.findViewById(R.id.webview);
            wb.getSettings().setJavaScriptEnabled(true);
            wb.loadUrl("http://www.google.com");
            wb.setWebViewClient(new HelloWebViewClient());
            dialog.setCancelable(true);
            dialog.setTitle("WebView");
            dialog.show();
        }
    });
