Question

this is my code for the logging in any help please

    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;
    import android.widget.EditText;
    import android.widget.Toast;

    import com.androidbegin.parselogintutorial.R;
    import com.parse.LogInCallback;
    import com.parse.ParseException;
    import com.parse.ParseUser;


    public class LoginActivity extends Activity {
        // Declare Variables
        Button loginbutton;
        String usernametxt;
        String passwordtxt;
        EditText password;
        EditText username;

        /** Called when the activity is first created. */
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            // Get the view from login.xml
            setContentView(R.layout.login);
            // Locate EditTexts in login.xml
            username = (EditText) findViewById(R.id.username);
            password = (EditText) findViewById(R.id.password);

            // Locate Buttons in main.xml
            loginbutton = (Button) findViewById(R.id.login);


            // Login Button Click Listener
            loginbutton.setOnClickListener(new OnClickListener() {

                public void onClick(View arg0) {
                    // Retrieve the text entered from the EditText
                    usernametxt = username.getText().toString();
                    passwordtxt = password.getText().toString();

                    // Send data to Parse.com for verification
                    ParseUser.logInInBackground(usernametxt, passwordtxt,
                            new LogInCallback() {
                                public void done(ParseUser user, ParseException e) {
                                        // If user exist and authenticated, send user to Welcome.class
                                    if(user !=null){    
                                    Intent intent = new Intent(
                                                LoginActivity.this,
                                                AddUserPage.class);
                                        startActivity(intent);
                                        Toast.makeText(getApplicationContext(),
                                                "Successfully Logged in",
                                                Toast.LENGTH_LONG).show();
                                        finish();
                                }else{
                                    Toast.makeText(getApplicationContext(), "No such user", Toast.LENGTH_LONG).show();
                                    username.setText("");
                                    password.setText("");
                                }}
                            });
                }
            });



        }
    }

I'd add an invisible (gone) indeterminate (circular) ProgressBar and set it visible when you click the Button. Then the new Activity is started and the login Activity (including the ProgressBar) disappears. — Phantômaxx, Dec 18 '14 at 16:31

Define a progress bar as private ProgressDialog mProgress;

in oncreate use this

mProgress = new ProgressDialog(context);
mProgress.setTitle("Processing...");
mProgress.setMessage("Please wait...");
mProgress.setCancelable(false);
mProgress.setIndeterminate(true);

Now this

// Login Button Click Listener
    loginbutton.setOnClickListener(new OnClickListener() {

        public void onClick(View arg0) {
            mProgress.show();
            // Retrieve the text entered from the EditText
            usernametxt = username.getText().toString();
            passwordtxt = password.getText().toString();

            // Send data to Parse.com for verification
            ParseUser.logInInBackground(usernametxt, passwordtxt,
                    new LogInCallback() {
                        public void done(ParseUser user, ParseException e) {
                                // If user exist and authenticated, send user to Welcome.class
                            if(user !=null){   
                            mProgress.dismiss(); 
                            Intent intent = new Intent(
                                        LoginActivity.this,
                                        AddUserPage.class);
                                startActivity(intent);
                                Toast.makeText(getApplicationContext(),
                                        "Successfully Logged in",
                                        Toast.LENGTH_LONG).show();
                                finish();
                        }else{
                            mProgress.dismiss();
                            Toast.makeText(getApplicationContext(), "No such user", Toast.LENGTH_LONG).show();
                            username.setText("");
                            password.setText("");
                        }}
                    });
        }
    });

Add a ProgressBar to your xml layout like this(make sure this is on the top of all other views so that it occupies all other views when its visible.

<ProgressBar
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:id="@+id/loadingProgress"
  android:indeterminate="true"
  android:visibility="false"/>

Then get the view reference inside the onCreate

ProgressBar pb =  findViewById(R.id.loadingProgress);

On public void onClick(View arg0) for loginbutton set the visibility to true for pb like pb.setVisibility(View.Visible)

In LogInCallback() in else part add pb.setVisiblity(View.Gone)

ProgressDialog is what you want. It's a modal dialog with a spinner that greys the background activity while it's showing. Start it before the network call and dismiss it when the call finishes.

ProgressDialog pd = new ProgressDialog(context);
pd.setTitle("Processing...");
pd.setMessage("Please wait.");
pd.setCancelable(false);
pd.setIndeterminate(true);
pd.show();

// do login call

then dismiss it when the call finished in the onDone method

pd.dismiss();

There are a few other options like ProgressBar which is a view that you will show/hide in your layout when the network call is happening. The ActionBar also has a stock ProgressBar that you can hide and show there if you like that look better. Put a progressBar on ActionBar
