错误：构造函数Object（EditText）未定义

Question

I'm getting an error in this method: "The constructor Object(EditText) is undefined"

private void setupAlert()
    {
        Log.d(TAG, "setupAlert()");
        LayoutInflater li = LayoutInflater.from(this);
        View promptsView = li.inflate(R.layout.emaildialog, null);
        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
        alertDialogBuilder.setView(promptsView);
        final EditText userInput = (EditText)promptsView.findViewById(R.id.editTxtEmailAddress);
        alertDialogBuilder.setCancelable(false).setPositiveButton("OK", new DialogInterface.OnClickListener()
        {
            public void onClick(DialogInterface dialog, int id)
            {
                updatePref(userInput.getText().toString());
                Log.d(MainActivity.TAG, "setupAlert: getPreference()=" + getPreference());
                takeSnapNow();
            }
        });
        AlertDialog alertDialog = alertDialogBuilder.create();
        alertDialog.show();
    }

protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.colour_selector);
        Log.d(TAG, "onCreate: getPreference()=" + getPreference());
        if (getPreference().equals("")) {
            setupAlert();
            takeSnapNow();
        } else {
            takeSnapNow();
        }
    }

private void takeSnapNow()
    {
        String fileName = "TempImage.jpg";
        ContentValues values = new ContentValues();
        values.put(MediaStore.Images.Media.TITLE, fileName);
        values.put(MediaStore.Images.Media.DESCRIPTION, "Captured by XYZ app");
        imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
        startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
    }

Please suggest the solution to this error.

Edit: Corrected the above error by removing UserInput as suggested by others. However the alertDialog is still not shown. The logic is to check the sharedpref initially in onCreate, and if not found, call setupAlert() method to get email ID from user. Any clues? Changed code updated in the above snippet.

Answer 1

DialogInterface.OnClickListener doesn't take an EditText as a constructor parameter and you don't need to do that ! you can use userInput without passing it to DialogInterface.OnClickListener , just use it as follow

alertDialogBuilder.setCancelable(false).setPositiveButton("OK", new DialogInterface.OnClickListener() {

Answer 2

Why are you using " new DialogInterface.OnClickListener(userInput) "?

Just use new DialogInterface.OnClickListener()
