我有问题。我正在使用浏览器类型的应用程序，一旦我完成授权应用程序。它不会将我重定向到我的网页。相反，我显示我重定向，但它仍然在同一页面上。任何想法如何处理这样的问题？ – 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(); 
    }

打开像对话框并在Menifeast.xml文件中注册。使用像对话框一样。

public class WebDialog extends Dialog 
{ 

    static final int      BLUE     = 0xFF6D84B4; 
    static final float[]     DIMENSIONS_DIFF_LANDSCAPE =

                    { 40, 60 }; 
    static final FrameLayout.LayoutParams FILL     = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT); 
    static final int      MARGIN     = 4; 
    static final int      PADDING     = 2; 
    static final String     DISPLAY_STRING   = "touch"; 

    private String      mUrl; 
// private DialogListener    mListener; 
    private ProgressDialog    mSpinner;

      return true; 
     } 

     @Override 
     public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
