How to Create List View in Android.

ListView is a view group that displays a list of scrollable items. The list items are automatically inserted to the list using an Adapter that pulls content from a source such as an array or database query and converts each item result into a view that's placed into the list.

For an introduction to how you can dynamically insert views using an adapter, read Building Layouts with an Adapter.

Step 1-

Create a Android Application Project "ContactDetail".

Step 2-

Create a Android XML file "activity_contact.xml".

<?xml version="1.0" encoding="utf-8"?>

<!--  Single List Item Design -->

<TextView xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/tvContact"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:padding="10dip"

    android:textSize="16dip"

    android:textStyle="bold" >

</TextView>

Step 3-

Create a another XML file "single_list_contact.xml".

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

  android:orientation="vertical"

  android:layout_width="match_parent"

  android:layout_height="match_parent">

  <TextView android:id="@+id/tvsinglecontact"

  android:layout_width="fill_parent"

  android:layout_height="wrap_content"

  android:textSize="25dip"

  android:textStyle="bold"

  android:padding="10dip"

  android:textColor="#ff00ff"/> 

</LinearLayout>

Step 4-

Create a java class "contacts.java".

package com.example.contactdetails;

import android.os.Bundle;

import android.app.ListActivity;

import android.content.Intent;

import android.view.View;

import android.widget.AdapterView;

import android.widget.AdapterView.OnItemClickListener;

import android.widget.ArrayAdapter;

import android.widget.ListView;

import android.widget.TextView;

public class Contacts extends ListActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

String[] contact_numbers= getResources().getStringArray(R.array.contact_numbers);

this.setListAdapter(new ArrayAdapter<String>(this,R.layout.activity_contacts,R.id.tvContact, contact_numbers));

ListView lv = getListView();

   lv.setOnItemClickListener(new OnItemClickListener() {

@Override

public void onItemClick(AdapterView<?> parent, View view, int position,

long id) {

// TODO Auto-generated method stub

String numbers= ((TextView)view).getText().toString();

Intent i= new Intent(getApplicationContext(), SingleListContact.class);

i.putExtra("numbers", numbers);

startActivity(i);

}

   

});

}

}

Step 5- Create a another java file "SingleListContact.java".

package com.example.contactdetails;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.widget.TextView;

public class SingleListContact extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.single_list_contact);

TextView txtContact=(TextView)findViewById(R.id.tvsinglecontact);

Intent i = getIntent();

              String numbers = i.getStringExtra("numbers");

        txtContact.setText(numbers);

}

}

Step 6- 

Create a xml file in the Value Folder name is "contect_list.xml";

<?xml version="1.0" encoding="utf-8"?>

<resources>

    <string-array name="contact_numbers">

        <item >Name</item>

<item >Name</item>

<item >Name</item>

<item >Name</item>

<item >Name</item>

<item >Name</item>

<item >Name</item>

<item >Name</item>         

so on...       

 </string-array>

</resources>

Step 7 -

Android manifest.xml 

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.example.contactdetails"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk

        android:minSdkVersion="8"

        android:targetSdkVersion="17" />

    <application

        android:allowBackup="true"

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme" >

        <activity

            android:name=".Contacts"

            android:label="@string/app_name" >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

        <activity

            android:name=".SingleListContact"

            android:label="Single List">

        </activity>

    </application>

</manifest>

Step 8-

Save and Run on the Emulator Machine or F11.
