Android Custom GridView - CardView With Images and Text


Android Custom GridView with CardViews,with images and text tutorial. Hi.Here's our plan:

  • Custom GridView With CardViews as our ViewItems.
  • Each cardview as our viewitem shall have images and text.
  • We then handle ItemClicks.
  • We are using BaseAdapter as our adapter of choice.

Tools Used

This example was written with the following tools:

  • Windows 8
  • AndroidStudio IDE
  • Genymotion Emulator
  • Language : Java

Source Code

Lets jump directly to the source code. Source code is well commented. Furthermore we have explained everything in the video tutorial.

Build.Gradle

  • Add CardView as a dependency.
apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.tutorials.hp.customgridviewcardviews"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.3.0'
    compile 'com.android.support:cardview-v7:23.3.0'

}

Spacecraft.java

  • Our Spacecraft class.
  • Is our data object.
  • Each Spacecraft has a name, propellant and image,
package com.tutorials.hp.customgridviewcardviews;

public class Spacecraft {
    int image;
    String name,propellant;

    public int getImage() {
        return image;
    }

    public void setImage(int image) {
        this.image = image;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPropellant() {
        return propellant;
    }

    public void setPropellant(String propellant) {
        this.propellant = propellant;
    }
}

CustomAdapter.java

  • Our adapter class.
  • Subclasses BaseAdapter.
  • Inflate model.xml into a view object.
  • Bind data
package com.tutorials.hp.customgridviewcardviews;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

import java.util.ArrayList;

public class CustomAdapter extends BaseAdapter{
    Context c;
    ArrayList<Spacecraft> spacecrafts;

    public CustomAdapter(Context c, ArrayList<Spacecraft> spacecrafts) {
        this.c = c;
        this.spacecrafts = spacecrafts;
    }

    @Override
    public int getCount() {
        return spacecrafts.size();
    }

    @Override
    public Object getItem(int i) {
        return spacecrafts.get(i);
    }

    @Override
    public long getItemId(int i) {
        return i;
    }

    @Override
    public View getView(int i, View view, ViewGroup viewGroup) {
        if(view==null)
        {
            view= LayoutInflater.from(c).inflate(R.layout.model,viewGroup,false);
        }

        final Spacecraft s= (Spacecraft) this.getItem(i);

        ImageView img= (ImageView) view.findViewById(R.id.spacecraftImg);
        TextView nameTxt= (TextView) view.findViewById(R.id.nameTxt);
        TextView propTxt= (TextView) view.findViewById(R.id.propellantTxt);

        //BIND
        nameTxt.setText(s.getName());
        propTxt.setText(s.getPropellant());
        img.setImageResource(s.getImage());

        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(c, s.getName(), Toast.LENGTH_SHORT).show();
            }
        });

        return view;
    }
}

MainActivity.java

  •  Launcher Activity.
  • Generate dummy data and pass to adapter class
package com.tutorials.hp.customgridviewcardviews;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.GridView;
import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

    CustomAdapter adapter;
    GridView gv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        gv= (GridView) findViewById(R.id.gv);

        adapter=new CustomAdapter(this,getData());
        gv.setAdapter(adapter);

    }
    private ArrayList getData()
    {
        ArrayList<Spacecraft> spacecrafts=new ArrayList<>();

        Spacecraft s=new Spacecraft();
        s.setName("Pioneer");
        s.setPropellant("Chemical Energy");
        s.setImage(R.drawable.pioneer);
        spacecrafts.add(s);

        s=new Spacecraft();
        s.setName("Spitzer");
        s.setPropellant("Warp Drive");
        s.setImage(R.drawable.spitzer);
        spacecrafts.add(s);

        s=new Spacecraft();
        s.setName("Enterprise");
        s.setPropellant("Anti Matter");
        s.setImage(R.drawable.enterprise);
        spacecrafts.add(s);

        s=new Spacecraft();
        s.setName("Hubble");
        s.setPropellant("Laser Beam");
        s.setImage(R.drawable.herbal);
        spacecrafts.add(s);

        s=new Spacecraft();
        s.setName("Voyager");
        s.setPropellant("Solar Energy");
        s.setImage(R.drawable.voyager);
        spacecrafts.add(s);

        s=new Spacecraft();
        s.setName("Kepler");
        s.setPropellant("Solar Energy");
        s.setImage(R.drawable.kepler);
        spacecrafts.add(s);

        s=new Spacecraft();
        s.setName("Rosetter");
        s.setPropellant("Nuclear Energy");
        s.setImage(R.drawable.rosetta);
        spacecrafts.add(s);

        s=new Spacecraft();
        s.setName("WMAP");
        s.setPropellant("Nuclear Energy");
        s.setImage(R.drawable.wmap);
        spacecrafts.add(s);

        s=new Spacecraft();
        s.setName("Columbia");
        s.setPropellant("Chemical Energy");
        s.setImage(R.drawable.columbia);
        spacecrafts.add(s);

        return spacecrafts;
    }

}
