Android Studio: Recyclerview Grid Layout Manager

Recyclerview is a powerful tool for creating list-like UI components in Android applications. In this tutorial, we'll explore how to use the GridLayoutManager with Recyclerview in Android Studio.

Step 1 - Create a New Project

To start, create a new project in Android Studio by going to File > New Project and filling in all the required details. For this example, let's create a simple project that demonstrates the usage of GridLayoutManager with Recyclerview.

Step 2 - Add Code to MainActivity.java

In the `MainActivity.java` file, add the following code:

```java

import android.os.Bundle;

import android.view.View;

import android.widget.Toast;

import androidx.appcompat.app.AppCompatActivity;

import androidx.recyclerview.widget.GridLayoutManager;

import androidx.recyclerview.widget.RecyclerView;

public class MainActivity extends AppCompatActivity {

RecyclerView recyclerView;

RecyclerView.Adapter adapter;

RecyclerView.LayoutManager layoutManager;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

recyclerView = (RecyclerView) findViewById(R.id.recyclerView);

recyclerView.setHasFixedSize(true);

layoutManager = new GridLayoutManager(this, 2);

recyclerView.setLayoutManager(layoutManager);

String'' data = {'Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5'};

adapter = new MyAdapter(data);

recyclerView.setAdapter(adapter);

}

```

Step 3 - Add Code to courservitem.xml

In the `courseritem.xml` file, add the following code:

```xml

android:layout_width='match_parent'

android:layout_height='wrap_content'

android:orientation='vertical'>

android:id='@+id/textView'

android:layout_width='match_parent'

android:layout_height='wrap_content'

android:textSize='20sp' />

```

Step 4 - Run the Application

Run the application and you should see a RecyclerView with a GridLayoutManager, displaying a list of items.

In this example, we've used the `GridLayoutManager` to arrange the items in the RecyclerView in a grid-like structure. We've also created a custom adapter to bind data to the RecyclerView. The `MyAdapter` class is responsible for inflating the layout file (`courseritem.xml`) and populating it with data.

In this tutorial, we've learned how to use the GridLayoutManager with Recyclerview in Android Studio. By following these steps, you can easily create a RecyclerView with a grid-like structure in your Android application.
