Creating activity to receive and display clicked item

Right click on Layout => New => Activity => Empty Activity => name it in this case i have named it activity_item.
Open your activity_item, Copy and Paste the code below.


<!--?xml version="1.0" encoding="utf-8"?-->
<relativelayout 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" tools:context="com.example.larntech.listviewcard.ItemActivity">
    <textview android:id="@+id/listdata" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerhorizontal="true" android:layout_margintop="105dp" android:text="Apple" android:textcolor="#000" android:textsize="30dp">

    <imageview android:id="@+id/imageView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/apple" android:layout_centerhorizontal="true" android:layout_below="@+id/listdata" android:layout_margintop="27dp">
</imageview></textview></relativelayout>

</imageview></textview></relativelayout>

Receiving and displaying clicked items

We are going to use intents to send and receive clicked item.
To send data between activities through intent we use.


intent.putExtra("name",fruitNames[i]);
intent.putExtra("image",fruitImages[i]);

intent.putExtra("name",fruitNames[i]);

intent.putExtra("image",fruitImages[i]);

To receive data through intent we use.


intent.getStringExtra("name");
intent.getIntExtra("image",0);

intent.getStringExtra("name");

intent.getIntExtra("image",0);

Open your ItemActivity, Copy and Paste the code below for receiving and displaying clicked item.


package com.example.larntech.listviewcard;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.MenuItem;
import android.widget.ImageView;
import android.widget.TextView;

public class ItemActivity extends AppCompatActivity {
    TextView listdata;
    ImageView imageView;

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

        listdata = findViewById(R.id.listdata);
        imageView = findViewById(R.id.imageView);
        Intent intent = getIntent();
        String receivedName =  intent.getStringExtra("name");
        int receivedImage = intent.getIntExtra("image",0);

        listdata.setText(receivedName);
        imageView.setImageResource(receivedImage);
        //enable back Button
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }
    //getting back to listview
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == android.R.id.home) {
            onBackPressed();
        }
        return super.onOptionsItemSelected(item);

    }
    @Override
    public void onBackPressed() {
        super.onBackPressed();
    }
}

package com.example.larntech.listviewcard;

import android.content.Intent;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.MenuItem;

import android.widget.ImageView;

import android.widget.TextView;

public class ItemActivity extends AppCompatActivity {

TextView listdata;

ImageView imageView;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_item);

listdata = findViewById(R.id.listdata);

imageView = findViewById(R.id.imageView);

Intent intent = getIntent();

String receivedName = intent.getStringExtra("name");

int receivedImage = intent.getIntExtra("image",0);

listdata.setText(receivedName);

imageView.setImageResource(receivedImage);

//enable back Button

getSupportActionBar().setDisplayHomeAsUpEnabled(true);

}

//getting back to listview

@Override

public boolean onOptionsItemSelected(MenuItem item) {

if (item.getItemId() == android.R.id.home) {

onBackPressed();

}

return super.onOptionsItemSelected(item);

}

@Override

public void onBackPressed() {

super.onBackPressed();

}

Initializing ListView and Setting ListView Data

Open your MainActivity.java class
We shall start with initializing our listview and then set data list view data.
To set list view data we need to create custom Adapter that extends base Adapter.
Copy and Paste the code below in your MainActivity.java.


package com.example.larntech.listviewcard;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    ListView listView;

    String[] fruitNames = {"Apple","Orange","Kiwi","Passion","Banana"};
    int[] fruitImages = {R.drawable.apple,R.drawable.oranges,R.drawable.kiwi,R.drawable.watermelon,R.drawable.banana};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //finding listview
        listView = findViewById(R.id.listview);

        CustomAdapter customAdapter = new CustomAdapter();
        listView.setAdapter(customAdapter);
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<!--?--> adapterView, View view, int i, long l) {
//               Toast.makeText(getApplicationContext(),fruitNames[i],Toast.LENGTH_LONG).show();
                Intent intent = new Intent(getApplicationContext(),ItemActivity.class);
                intent.putExtra("name",fruitNames[i]);
                intent.putExtra("image",fruitImages[i]);
                startActivity(intent);

            }
        });


    }

    private class CustomAdapter extends BaseAdapter {
        @Override
        public int getCount() {
            return fruitImages.length;
        }

        @Override
        public Object getItem(int i) {
            return null;
        }

        @Override
        public long getItemId(int i) {
            return 0;
        }

        @Override
        public View getView(int i, View view, ViewGroup viewGroup) {
            View view1 = getLayoutInflater().inflate(R.layout.row_data,null);
            //getting view in row_data
            TextView name = view1.findViewById(R.id.fruits);
            ImageView image = view1.findViewById(R.id.images);

            name.setText(fruitNames[i]);
            image.setImageResource(fruitImages[i]);
            return view1;
        }
    }
}

package com.example.larntech.listviewcard;

import android.content.Intent;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.view.ViewGroup;

import android.widget.AdapterView;

import android.widget.BaseAdapter;

import android.widget.ImageView;

import android.widget.ListView;

import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

ListView listView;

String[] fruitNames = {"Apple","Orange","Kiwi","Passion","Banana"};

int[] fruitImages = {R.drawable.apple,R.drawable.oranges,R.drawable.kiwi,R.drawable.watermelon,R.drawable.banana};

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

//finding listview

listView = findViewById(R.id.listview);

CustomAdapter customAdapter = new CustomAdapter();

listView.setAdapter(customAdapter);

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

@Override

public void onItemClick(AdapterView adapterView, View view, int i, long l) {

// Toast.makeText(getApplicationContext(),fruitNames[i],Toast.LENGTH_LONG).show();

Intent intent = new Intent(getApplicationContext(),ItemActivity.class);

intent.putExtra("name",fruitNames[i]);

intent.putExtra("image",fruitImages[i]);

startActivity(intent);

}

});

}

private class CustomAdapter extends BaseAdapter {

@Override

public int getCount() {

return fruitImages.length;

}

@Override

public Object getItem(int i) {

return null;

}

@Override

public long getItemId(int i) {

return 0;

}

@Override

public View getView(int i, View view, ViewGroup viewGroup) {

View view1 = getLayoutInflater().inflate(R.layout.row_data,null);

//getting view in row_data

TextView name = view1.findViewById(R.id.fruits);

ImageView image = view1.findViewById(R.id.images);

name.setText(fruitNames[i]);

image.setImageResource(fruitImages[i]);

return view1;
