• Four CheckBox widgets labeled with:
  • Painting
  • Drawing
  • mad_experiment_2_2

• A Button labeled "Check" to trigger logic based on selected checkboxes (can be implemented in MainActivity.java).

🛠️ Built With

• Android Studio
• Java
• XML Layout (RelativeLayout)

🚀 Getting Started

1. Clone the repository:

   git clone https://github.com/your-username/android-checkbox-example.git

Open in Android Studio:

Open Android Studio → File → Open → Navigate to the project directory.

Build and Run:

Connect an emulator or Android device.

Click the Run button ▶️.

📄 How it Works The layout file activity_main.xml defines four checkboxes and one button using RelativeLayout. Each checkbox has a unique ID and is placed below the previous one.

The button with the onClick="Check" attribute calls a method in MainActivity.java when clicked. You can customize the Check() method to check which checkboxes are selected and perform any action accordingly.

java Copy Edit public void Check(View view) { CheckBox cb1 = findViewById(R.id.checkBox); CheckBox cb2 = findViewById(R.id.checkBox2); CheckBox cb3 = findViewById(R.id.checkBox3); CheckBox cb4 = findViewById(R.id.checkBox4);

StringBuilder result = new StringBuilder("Selected:\n");
if (cb1.isChecked()) result.append("Painting\n");
if (cb2.isChecked()) result.append("Drawing\n");
if (cb3.isChecked()) result.append("mad_experiment_2_2\n");
if (cb4.isChecked()) result.append("checkbox\n");

Toast.makeText(this, result.toString(), Toast.LENGTH_SHORT).show();

} 📌 TODO Implement logic inside the Check() method.

Add more functionality based on checkbox selection.

Improve the UI using Material Components.
