XML Layout

Create a main layout which contains LinearLayout as parent view and add ListView as a child to it .

file : activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

    <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
     />
</LinearLayout>

Create list_item.xml inside layout directory ,this layout is used to defines the design of each row items in a list view

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

        android:layout_width="70dp"
        android:layout_height="70dp"
        android:contentDescription="desc"
        android:paddingLeft="10dp"
        android:paddingRight="10dp" />

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

Bean Class

Create a Bean Class RowItem which is used for setting and getting row data's of each items in ListView ( member_name , profile_pic_id, status, contactType ) .

file : RowItem.java
package com.pavan.mylistview;

public class RowItem {

 private String member_name;
 private int profile_pic_id;
 private String status;
 private String contactType;

 public RowItem(String member_name, int profile_pic_id, String status,
   String contactType) {

 }

 public String getMember_name() {

 }

 public void setMember_name(String member_name) {

 }

 public void setProfile_pic_id(int profile_pic_id) {

 }

 public String getContactType() {

 }

 public void setContactType(String contactType) {
  this.contactType = contactType;
 }

}

Adapter

Create a custom adapter which extends BaseAdapter , this is used for inflating each row items of the listview

file :CustomAdapter.java
package com.pavan.mylistview;

public class CustomAdapter extends BaseAdapter {

 Context context;
 List<RowItem> rowItems;

 CustomAdapter(Context context, List<RowItem> rowItems) {
  this.context = context;
  this.rowItems = rowItems;
 }

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

Activity

Finally In the main activity inside the onCreate method set the content of the view with main layout(R.layout.activity_main) which is defined above and set the above defined custom adapter for ListView .

file : MainActivity.java
package com.pavan.mylistview;

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.content.res.TypedArray;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;

public class MainActivity extends Activity implements OnItemClickListener {

 String[] member_names;
 TypedArray profile_pics;
 String[] statues;
 String[] contactType;

 List<RowItem> rowItems;
 ListView mylistview;

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

  rowItems = new ArrayList<RowItem>();

  member_names = getResources().getStringArray(R.array.Member_names);

  profile_pics = getResources().obtainTypedArray(R.array.profile_pics);

  statues = getResources().getStringArray(R.array.statues);

  contactType = getResources().getStringArray(R.array.contactType);

  for (int i = 0; i < member_names.length; i++) {
   RowItem item = new RowItem(member_names[i],
     profile_pics.getResourceId(i, -1), statues[i],
     contactType[i]);
   rowItems.add(item);
  }

  mylistview = (ListView) findViewById(R.id.list);
  CustomAdapter adapter = new CustomAdapter(this, rowItems);
  mylistview.setAdapter(adapter);
  profile_pics.recycle();
  mylistview.setOnItemClickListener(this);

 }

 @Override
 public void onItemClick(AdapterView<?> parent, View view, int position,
   long id) {

  String member_name = rowItems.get(position).getMember_name();
  Toast.makeText(getApplicationContext(), "" + member_name,
    Toast.LENGTH_SHORT).show();
 }
