原文:

In the following code, I tried to dismiss the AlertDialog box but to no avail. However, if I remove compareKeys() function, the dismiss will work. So how can I make it dismiss after calling the compareKeys() function?

翻译:

在下面的代码中，我尝试去释放AlertDialog对话框，但释放无效。然而，我去掉 compareKeys()方法后，释放AlertDialog是正常工作的。我如何在释放AlertDialog对话框后正常调用compareKeys()方法？

 public void promptAdministratorPassword() {
     AlertDialog.Builder alert = new AlertDialog.Builder(this);

     alert.setTitle("Alert!");
     alert.setMessage("Please enter your password: ");

     // Set an EditText view to get user input
     final EditText input = new EditText(this);
     alert.setView(input);

     alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
         public void onClick(DialogInterface dialog, int whichButton) {
             password = input.getText().toString();

             if (password.equals("password")) {
                 try {
                     compareKeys();
                 } catch (IOException | NoSuchAlgorithmException | InvalidKeySpecException e) {
                     e.printStackTrace();
                 }
             }
             dialog.dismiss();
         }
     });

     alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
         public void onClick(DialogInterface dialog, int whichButton) {
             // Canceled.
         }
     });
     alert.show();
 }

解决方案原文：Call dialog.dismiss() before password = input.getText().toString() and add dialog.dismiss() inside setNegativeButton's OnClickListener too.

解决方案翻译：将password = input.getText().toString()放到调用dialog.dismiss()之前，并将dialog.dismiss()放到setNegativeButton的OnClickListener方法中。
