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。
