Parse.com I do not want to get the currentuser, but the login user and password

Hello everyone,

I have this app I am playing with around and when I tried to change this block of code it throws parseException error.

post.put("title", postTitle); post.put("content", postContent); post.put("author",ParseUser.getCurrentUser()); <--right here when I am changing it to: post.put("author",ParseUser.login(username,password)); it throws in error even though I have defined the variables in my code username and password and I have converted them from edittext to string. I even extend them in my current class, but no luck. I will post part of my code so you get the idea on what I am looking for.

Here is my loginClass:

import android.support.v7.app.ActionBarActivity; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; import android.widget.EditText; import android.widget.Button; import android.widget.TextView; import android.view.Window; import android.view.View; import android.content.Intent; import android.app.AlertDialog; import com.parse.ParseUser; import com.parse.LogInCallback; import com.parse.ParseException; import android.app.Activity;

public class LoginActivity extends ActionBarActivity {

protected TextView mSignUpTextView;
protected EditText mUsername;
protected EditText mPassword;
protected Button mLoginButton;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);

//TextView Button mSignUpTextView = (TextView) findViewById(R.id.signUpText); mSignUpTextView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) {

            Intent intent = new Intent(LoginActivity.this, SignUpActivity.class);
            startActivity(intent);

        }
    });
    mUsername = (EditText) findViewById(R.id.usernameField);
    mPassword = (EditText) findViewById(R.id.passwordField);
    mLoginButton = (Button) findViewById(R.id.loginButton);
    mLoginButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            String username = mUsername.getText().toString();
            String password = mPassword.getText().toString();


            username = username.trim();
            password = password.trim();


            if (username.isEmpty() || password.isEmpty()) {
                AlertDialog.Builder builder = new AlertDialog.Builder(LoginActivity.this);
                builder.setMessage(R.string.loginmessage)
                        .setTitle(R.string.login_error_title)
                        .setPositiveButton(android.R.string.ok, null);
                AlertDialog dialog = builder.create();
                dialog.show();
            } else
            // create the new user here
            {
                ParseUser.logInInBackground(username, password, new LogInCallback() {
                    @Override
                    public void done(ParseUser parseUser, ParseException e) {
                        if (e == null) {
                            //Success
                            Intent intent = new Intent(LoginActivity.this, MainActivity.class);
                            intent.addFlags(intent.FLAG_ACTIVITY_NEW_TASK);
                            intent.addFlags(intent.FLAG_ACTIVITY_CLEAR_TASK);
                            startActivity(intent);
                        } else {
                            AlertDialog.Builder builder = new AlertDialog.Builder(LoginActivity.this);
                            builder.setMessage(e.getMessage())
                                    .setTitle(R.string.login_error_title)
                                    .setPositiveButton(android.R.string.ok, null);
                            AlertDialog dialog = builder.create();
                            dialog.show();
                        }
                    }
                });

            }

        }
    });

}

}

Here is my editNote class in which I am trying to implement the method I mentioned above:

import android.app.Activity; import android.app.AlertDialog; import android.content.Intent; import android.os.Bundle; import android.util.Log; import android.view.View; import android.view.Window; import android.widget.Button; import android.widget.EditText; import android.widget.Toast; import com.parse.GetCallback; import com.parse.ParseObject; import com.parse.ParseQuery; import com.parse.ParseUser; import com.parse.SaveCallback;

public class EditNoteActivity extends Activity {

private Note note;
private EditText titleEditText;
private EditText contentEditText;
private String postTitle;
private String postContent;
private Button saveNoteButton;





@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
    //getActionBar().setDisplayHomeAsUpEnabled(true);
    setContentView(R.layout.activity_edit_note);

    Intent intent = this.getIntent();

    titleEditText = (EditText) findViewById(R.id.noteTitle);
    contentEditText = (EditText) findViewById(R.id.noteContent);

    if (intent.getExtras() != null) {
        note = new Note(intent.getStringExtra("noteId"), intent.getStringExtra("noteTitle"), intent.getStringExtra("noteContent"));

        titleEditText.setText(note.getTitle());
        contentEditText.setText(note.getContent());
    }

    saveNoteButton = (Button)findViewById(R.id.saveNote);
    saveNoteButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            saveNote();

        }
        private void saveNote() {

            postTitle = titleEditText.getText().toString();
            postContent = contentEditText.getText().toString();

            postTitle = postTitle.trim();
            postContent = postContent.trim();

            // If user doesn't enter a title or content, do nothing
            // If user enters title, but no content, SAVE
            // If user enters content with no title, give warning
            // If user enters both title and content, SAVE

            if (!postTitle.isEmpty()) {

                    post.put("content", postContent);
                    post.put("author", ParseUser.getCurrentUser());  // this is the part where I am trying to pass the ParseUser.login(username, password)); to help view to content by any logging users

                    setProgressBarIndeterminateVisibility(true);
                    post.saveInBackground(new SaveCallback() {

                                Log.d(getClass().getSimpleName(), "User update error: " + e);
                            }
                        }

                                    }
                                });
                            }

}

}

Hopefully that was clear.

Thanks in advance
