我有問題。我正在使用瀏覽器類型的應用程序,一旦我完成授權應用程序。它不會將我重定向到我的網頁。相反,我顯示我重定向,但它仍然在同一頁面上。任何想法如何處理這樣的問題? – insomiac 2011-06-01 19:46:32

Context mContext = this; 
    AlertDialog.Builder alert = new AlertDialog.Builder(mContext); 

    alert.setTitle("Riga"); 
    WebView wv = new WebView(mContext); 
    String html = "<html><body>some html here</body></html>"; 

    wv.loadData(html, "text/html", "UTF-8"); 
    alert.setView(wv); 
    alert.setIcon(R.drawable.icon); 
    alert.setPositiveButton("Yes", new DialogInterface.OnClickListener(){ 
    public void onClick(DialogInterface dialog, int id){ 
     Toast.makeText(getApplicationContext(), "Success", Toast.LENGTH_SHORT).show(); 
    } 
    }); 
    alert.setNegativeButton("No", new DialogInterface.OnClickListener(){ 
    public void onClick(DialogInterface dialog, int id){ 
     Toast.makeText(getApplicationContext(), "Fail", Toast.LENGTH_SHORT).show(); 
    } 
    }); 
    alert.show();

打開像對話框並在Menifeast.xml文件中註冊。使用像對話框一樣。

public class WebDialog extends Dialog

    static final int      BLUE     = 0xFF6D84B4;

                    { 40, 60 }; 
    static final FrameLayout.LayoutParams FILL     = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT); 
    static final int      MARGIN     = 4;
