Android WebView未在对话框中加载URL

Android WebView未在对话框中加载URL,android,webview,dialog,Android,Webview,Dialog,我正在尝试制作一个显示网络视图的Android对话框: final Dialog dialog = new Dialog(mActivity); dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); dialog.setContentView(R.layout.layout); WebView webView = (WebView)dialog.findViewById(R.id.webview); webView.setWebChromeC

我正在尝试制作一个显示网络视图的Android对话框:

final Dialog dialog = new Dialog(mActivity);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.layout);
WebView webView = (WebView)dialog.findViewById(R.id.webview);
webView.setWebChromeClient(new WebChromeClient());

String customHtml = "<html><body>WebViewTest</body></html>";
webView.loadData(customHtml, "text/html", "UTF-8");
dialog.show();
final Dialog=新建对话框(mActivity);
对话框.requestWindowFeature(窗口.FEATURE\u无\u标题);
setContentView(R.layout.layout);
WebView WebView=(WebView)dialog.findviewbyd(R.id.WebView);
setWebChromeClient(新的WebChromeClient());
字符串customHtml=“WebViewTest”;
加载数据(自定义html、“文本/html”、“UTF-8”);
dialog.show();
但什么都没有发生。webview似乎没有大小

我被要求提供xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:minHeight="300dp"
    android:padding="10sp"
    android:background="#0ff"
    android:orientation="vertical">
    <WebView
        android:background="#f0f"
        android:id="@+id/webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
</LinearLayout>

我建议看这里:

与其使用AlertDialog,它将更好地满足您的需求:

AlertDialog.Builder alert = new AlertDialog.Builder(this); 
alert.setTitle("Title here");

WebView wv = new WebView(this);
wv.loadUrl("http:\\www.google.com");
wv.setWebViewClient(new WebViewClient() {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }
});

alert.setView(wv);
alert.setNegativeButton("Close", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int id) {
        dialog.dismiss();
    }
});
alert.show();
final Dialog=新建对话框(mActivity);
对话框.requestWindowFeature(窗口.FEATURE\u无\u标题);
setContentView(R.layout.layout);
WebView WebView=(WebView)dialog.findviewbyd(R.id.WebView);
setWebChromeClient(新的WebChromeClient());
字符串customHtml=“WebViewTest”;
loadData(customHtml,“text/html;charset=UTF-8”,null);
dialog.show();

发布用于webview的布局。尝试此
webview.loadData(customHtml,“text/html;charset=UTF-8”,null)
@JackFinch,如果这个答案对你有帮助,那么勾选绿色标记,而不是简单地说“谢谢”,这样对未来的用户也有帮助。
final Dialog dialog = new Dialog(mActivity);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.layout);
WebView webView = (WebView)dialog.findViewById(R.id.webview);
webView.setWebChromeClient(new WebChromeClient());
String customHtml = "<html><body>WebViewTest</body></html>";
webView.loadData(customHtml, "text/html; charset=UTF-8", null);
dialog.show();
