package com.rajeshvijayakumar.model;

import com.mobsandgeeks.adapters.InstantText;
import com.rajeshvijayakumar.insta.R;

public class Person {

    private String name;
    private String phoneNo;
    private String emailId;

    public Person(String name, String phoneNo, String emailId) {
        this.name = name;
        this.phoneNo = phoneNo;
        this.emailId = emailId;
    }

    @InstantText(viewId = R.id.name)
    public String getName() {
        return name;
    }

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

    @InstantText(viewId = R.id.phone_no, formatString = "Mob : %s")
    public String getPhoneNo() {
        return phoneNo;
    }

    public void setPhoneNo(String phoneNo) {
        this.phoneNo = phoneNo;
    }

    @InstantText(viewId = R.id.email, formatString = "Email : %s")
    public String getEmailId() {
        return emailId;
    }

    public void setEmailId(String emailId) {
        this.emailId = emailId;
    }
}

MainActivity.java

package com.rajeshvijayakumar.insta;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ListView;

import com.mobsandgeeks.adapters.InstantAdapter;
import com.rajeshvijayakumar.model.Person;

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mPersonListView = (ListView) findViewById(R.id.person_list_view);
        mInsAdapter = new InstantAdapter<Person>(this, R.layout.list_item, Person.class, getPersons());
        mPersonListView.setAdapter(mInsAdapter);
