custom listview with adapter in android with source code

How to display items listview in an android

each item are displayed vertically scrollable list.

That is easy to display each item's listview with automatically scrollable.

In this blog post, we will use an Adapter to inserted items into the list automatically.

Start android studio.

Name your project.

MainActivity.java

package com.pd.listview;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
ListView listView;
TextView textView;
String[]list={"one","two","three","four","five","six","seven", "eight","nine","ten"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listView=(ListView)findViewById(R.id.listview);
        textView=(TextView)findViewById(R.id.textview);

        final ArrayAdapter<String>adapter=new ArrayAdapter<String>(this,R.layout.singledata,R.id.textview,list);
        listView.setAdapter(adapter);

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            String value=adapter.getItem(position);
                Toast.makeText(MainActivity.this,value, Toast.LENGTH_SHORT).show();
            }
        });
    }
}

Now we will create listview 

activity_main.java

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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=".MainActivity">

    <ListView
        android:id="@+id/listview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_editor_absoluteX="180dp"
        app:layout_editor_absoluteY="136dp" />
</androidx.constraintlayout.widget.ConstraintLayout>

We will create an XML file to show the data in the text view. 

singledata.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="@dimen/mt"
        android:src="@drawable/ic_baseline_arrow_forward_ios_24" />

    <TextView
        android:id="@+id/textview"
        android:layout_width="wrap_content"
        android:layout_height="50dp"
        android:layout_marginLeft="@dimen/ml"
        android:layout_marginTop="@dimen/mt"
        android:text="@string/app_name"
        android:textSize="@dimen/ts" />

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignEnd="@+id/textview"
        android:layout_alignParentEnd="true"
        android:layout_marginTop="@dimen/mt"
        android:layout_marginRight="@dimen/mr"
        android:src="@drawable/ic_baseline_add_24" />

</RelativeLayout>

dimens.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="mr">5dp</dimen>
    <dimen name="mt">10dp</dimen>
    <dimen name="ml">25dp</dimen>
    <dimen name="ts">20dp</dimen>
</resources>
