網頁視圖裏面彈出窗口的Android

enter image description here 網頁視圖裏面彈出窗口的Android

嗨，我有一個問題如上圖中，左邊有一個網頁視圖內的按鈕。當我點擊按鈕時，應該會出現android中的popup窗口。在那個彈出窗口中，我需要一個webview。現在它的所有工作正常，沒有在彈出窗口中的web視圖。

這個彈出窗口是由JavaScript接口

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(); 
     }; 
    } 

}

請幫助

請提供更多的細節，以你的問題是什麼。 – Necreaux

試試這個調用。

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();
