GridView with Image and Text

GridView

This tutorial shows how to display a Map List containing texts and images in a Custom GridView.

Step 1:¬†Create a new project with name GridViewExample and package name com.myexample.gridview. Select File/New/New Project. Fill the forms and click “Finish” button.

Step 2: Open res/layout/xml (or) main.xml and add following code. Here we add a GridView.

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

	<GridView
		android:layout_height="match_parent"
		android:layout_width="match_parent"
		android:columnWidth="130dp"
        android:gravity="center"
        android:numColumns="auto_fit"
		android:id="@+id/mainGridView1"/>

</LinearLayout>

Step 3: In res/drawable/ directory add images to be used in ListView. E.g. ic_info_white_24dp.png, ic_lock_white_24dp.png, ic_security_white.png, ic_volume_up_white.png, home.png, ic_launcher.

Step 4: In res/layout/ directory add a new file list_item.xml and add following code. Here we add a TextView for displaying text and an ImageView for displaying images.

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout
	xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="match_parent"
	android:layout_height="wrap_content"
	android:orientation="vertical"
	android:padding="8dp"
	android:gravity="center_horizontal"
	android:background="#375782">

	<ImageView
		android:layout_height="100dp"
		android:layout_width="100dp"
		android:scaleType="fitCenter"
		android:id="@+id/listitemImageView1"/>

	<TextView
		android:layout_height="wrap_content"
		android:textAppearance="?android:attr/textAppearanceMedium"
		android:layout_width="wrap_content"
		android:text="Medium Text"
		android:textColor="#FEFEFE"
		android:id="@+id/listitemTextView1"/>

</LinearLayout>

Step 5: Open app/src/main/java/package and open MainActivity.java. Add following code in it. Here we create a Map list with a title and image at each position, and set an adapter to display this in GridView.

package com.myexample.gridview;

import android.app.*;
import android.os.*;
import android.view.*;
import android.view.View.*;
import android.widget.*;
import java.util.*;
import android.content.*;

public class MainActivity extends Activity {

	private GridView gridview1;
	// Create a new Array of type HashMap
    private ArrayList<HashMap<String, Object>> maplist = new ArrayList<>();
    
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		
		gridview1 = (GridView) findViewById(R.id.mainGridView1);
		
		gridview1.setOnItemClickListener(new GridView.OnItemClickListener(){
			@Override
			public void onItemClick(AdapterView<?> p1, View p2, int p3, long p4){
				Toast.makeText(getApplicationContext(), maplist.get(p3).get("title").toString(), Toast.LENGTH_LONG).show();
			}
		});
		
		// Add items to the Map list
        {
            HashMap<String, Object> _item = new HashMap<>();
            _item.put("title", "Info");
            _item.put("icon", R.drawable.ic_info_white_24dp);
            maplist.add(_item);
        }
        {
            HashMap<String, Object> _item = new HashMap<>();
            _item.put("title", "Privacy Policy");
            _item.put("icon",  R.drawable.ic_lock_white_24dp);
            maplist.add(_item);
        }
        {
            HashMap<String, Object> _item = new HashMap<>();
            _item.put("title", "Security");
            _item.put("icon",  R.drawable.ic_security_white);
            maplist.add(_item);
        }
        {
            HashMap<String, Object> _item = new HashMap<>();
            _item.put("title", "Volume");
            _item.put("icon",  R.drawable.ic_volume_up_white);
            maplist.add(_item);
        }
        {
            HashMap<String, Object> _item = new HashMap<>();
            _item.put("title", "Home");
            _item.put("icon",  R.drawable.home);
            maplist.add(_item);
        }
		{
            HashMap<String, Object> _item = new HashMap<>();
            _item.put("title", "Launcher");
            _item.put("icon",  R.drawable.ic_launcher);
            maplist.add(_item);
        }
		
		GridAdapter adapter = new GridAdapter(this);
		gridview1.setAdapter(adapter);
	}
	
	public class GridAdapter extends BaseAdapter {
		private Context mContext;
		public GridAdapter(Context c) {
			mContext = c;
		}
		public int getCount() {
			return maplist.size();
		}
		public Object getItem(int position) {
			return null;
		}
		public long getItemId(int position) {
			return 0;
		}
		public View getView(int position, View convertView, ViewGroup parent) {
			View v = convertView;
            // Inflate the layout for each list item
            LayoutInflater _inflater = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            if (v == null) {
                v = _inflater.inflate(R.layout.list_item, null);
            }
            // Get the TextView and ImageView from CustomView for displaying item
            TextView txtview = (TextView) v.findViewById(R.id.listitemTextView1);
            ImageView imgview = (ImageView) v.findViewById(R.id.listitemImageView1);

            // Set the text and image for current item using data from map list
            txtview.setText(maplist.get(position).get("title").toString());
            imgview.setImageResource(maplist.get(position).get("icon"));
			return v;
		}
	}
	
}

Output:
Now run the app. The app will display a GridView with icons and texts.
