Online Complaint Management System Android App with Source Code

In this tutorial, you will understand how to build a basic complaint management application using Android Studio.

What is a complaint management App?

A complaint management app is basically an app to manage and resolve the queries of the people. It can be used by companies to resolve the queries of their customers or it can be used by the government to resolve the queries of the public/people.

The Flow of the Application

This is an application to resolve the queries of the public. This app will be used by people to complaint about problems in their local area. Problems like garbage, water-related problems, etc will be taken to the municipal corporations and they will see the problem and will resolve the problems.

There will be 2 panels in this app. The first is a user panel and the second is a government panel.

User Panel

In this panel, the user or the public will put their complaints about problems in their local area. This will have a login and signup screen. After that, there will be a dashboard. The users can see their complaints on the dashboard and the status of the complaint. The user can also add new complaints and add images to state their problems more clearly.

Government Panel

In this panel, the government will see all the complaints added by the public and will resolve them. This will also have a login and signup screen. After that, there will be a dashboard. The government can see all the problems placed by people on the dashboard. They can click on any problem and solve the issue and change its status to work in progress or complete so that the user who posted the complaint can see it.

Software Requirement

You should be familiar with the following tech to understand the project.

• Java – Our application logic is written in Java.
• XML – The application is designed using the XML markup language.
• Firebase – Firebase will be used as the backend in this project.
• Android Studio – It’s a platform that allows us to create apps for Android devices.

Hardware Requirement

Hardware configuration to build this project:

• 64 Bit Windows 8/10
• Minimum 4GB ram for android studio
• Minimum 12GB of disk space for SDK, java, and IDE
• 1280 x 800 minimum screen resolution

Developing the Complaint management app

Let’s look at the files that we created for the complaint management app.

1. Activity_main.xml is the first file that will contain our code of dashboard.

2. There is a MainActivity.java that will handle the logic part of the above files.

3. After that, we created some files for our login and signup screens and their corresponding java files to handle its logic.

4. We created the files for the user and government dashboard. Also, we created their java files to handle their logic.

5. Some other important files

• Themes.xml: Theme of the app

Files Required

Activity_main.xml :

<androidx.recyclerview.widget.RecyclerView
        android:id="@+id/rv_showAllFood"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/ll_layout"
        tools:listitem="@layout/complaint_list_item" />

The above xml code is the code of the recycler view. This recycler view will show all the complaints the user has posted.

Activity_main.java :

AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
View view = LayoutInflater.from(MainActivity.this).inflate(R.layout.alert_add_complaint, null, false);
builder.setView(view);

EditText et_description = view.findViewById(R.id.et_description);
iv_complaintImage = view.findViewById(R.id.iv_complaintImage);
Spinner spino = view.findViewById(R.id.sp_department);
Button btn_create = view.findViewById(R.id.btn_addComplaint);
spino.setOnItemSelectedListener(this);

ArrayAdapter ad = new ArrayAdapter(MainActivity.this, android.R.layout.simple_spinner_item, courses);
ad.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

spino.setAdapter(ad);

AlertDialog alertDialog = builder.create();

storageReference = FirebaseStorage.getInstance().getReference().child("Uploads");

iv_complaintImage.setOnClickListener(new View.OnClickListener() {
  
alertDialog.show();

This code will be used to add a new complaint by the user. This will open a dialog box. In that dialog box, you have to add your new complaint.
