Build a Simple Android App to Display Student Details

Build a Simple Android App to Display Student Details (Student Details App)

In this tutorial, we’ll walk through the steps to create a basic Android application that displays a student’s details such as name, and marks. This is a great starting project for Android development using Java.

🛠 What You’ll Learn

• Creating a new Android Studio project
• Designing a layout with TextViews
• Writing Java code to display student data
• Running the app on an emulator or physical device

📦 Step 1: Create a New Project

1. Open Android Studio
2. Click on “New Project”
3. Choose Empty Activity
4. Name it: StudentDetailsApp
5. Language: Java
6. Click Finish

🖼 Step 2: Design the Layout (XML)

Go to res/layout/activity_main.xml and replace the default content with the following:

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="10dp"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/nameText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Student name: Amol Chaudhari"
        android:textSize="24sp" />

    <TextView
        android:id="@+id/marksText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Marks: 75.00"
        android:textSize="24sp" />
</LinearLayout> 

🧠 Step 3: Add Java Code

Open MainActivity.java and update the code as follows:

MainActivity.java

package com.example.studentdetailsapp;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {
    TextView nameText, marksText;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        nameText = findViewById(R.id.nameText);
        marksText = findViewById(R.id.marksText);
        
        // Sample student data
        String name = "Amol Chaudhari";
        String marks = "75.00";
        
        // Set data to TextViews
        nameText.setText("Studet name: " + name);
        marksText.setText("Marks: " + marks);
    }
}

▶️ Step 4: Run the App
Click the Run ▶️ button in Android Studio.

Choose your emulator or connected Android device.

The app will launch and display student details on the screen.

📱 OUTPUT

📌 Optional Enhancements
Add an image of the student using ImageView
Use EditText fields to allow user input
Display multiple students using a RecyclerView
✅ Summary
You’ve just built a simple Android app that:
Uses a layout with TextView elements
Assigns and displays static student data in Java
Runs on a real or virtual Android deviceThis project is a solid foundation for learning how to handle data, build user interfaces, and understand Android lifecycle basics.
