嗨，如上图所示，我遇到了一个问题，左侧有一个 webview 内的按钮。当我单击按钮时，应该会出现 android 中的弹出窗口。在那个弹出窗口中，我需要一个 webview。现在，在弹出窗口中没有 webview 的情况下一切正常。

这个弹出窗口是由javascript接口调用的

public class AppJavaScriptProxy {

    private Activity activity = null;

    public AppJavaScriptProxy() {

    }

    @JavascriptInterface
    public String showMessage(String footNoteNo) {
        Integer footNoteNoInt = Integer.parseInt(footNoteNo);
        footnote = myDbHelper.getFootnote(chapterNumber, footNoteNoInt);

        try {

            LayoutInflater inflater = (LayoutInflater) HomeActivity.this
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View layout = inflater.inflate(R.layout.footnote_popup,
                    (ViewGroup) findViewById(R.id.popup_footnote));
            popup = new PopupWindow(layout, ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT, true);
            popup.showAtLocation(layout, Gravity.CENTER, 0, 0);
            txt_footnote=(TextView) layout.findViewById(R.id.text_footnote);
            txt_footnote.setTypeface(malayalamfont);
            popup_close = (ImageButton) layout.findViewById(R.id.btn_close_popup);
            txt_footnote.setText(footnote);

            final WebView footnoteWView = (WebView) layout.findViewById(R.id.footnotePopupWebview);
            footnoteWView.getSettings().setJavaScriptEnabled(true);
           footnoteWView.loadUrl("file:///android_asset/www/footNotePopup.html");
            footnoteWView.clearCache(true);

           footnoteWView.setWebViewClient(new WebViewClient(){
                public void onPageFinished(WebView view, String url){                        footnoteWView.loadUrl("javascript:getFootnote('" + footnote + "')");
                }
            });
            popup_close.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    popup.dismiss();
                }
            });
        }
        catch (Exception e) {
            e.printStackTrace();
        };
    }

}

请帮忙

试试这个。

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

WebView wv = new WebView(this);
wv.loadUrl("http:\\www.yourweb.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();
