WebView 未在对话框中加载 URL

Question

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();

但是什么也没有发生。网络视图似乎没有大小

有人问我 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>

Answer 1

我建议看这里：android: webview inside dialog or popup

最好使用 AlertDialog，它会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();

Answer 2

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();

WebView 未在对话框中加载 URL

WebView not loading URL in Dialog
