can any one help me how to transfer some data through this method

Intent i = new Intent(Register.this,RegisterForm.class);
i.putExtra("name", yourdata);//i assume you are adding some string data
startChildActivity("Register", i);

//in RegisterForm.class

Intent i = RegisterForm.this.getIntent();
i.getStringExtra("name", "default Value you want");

You have to implement an interface called Parecelable and write your object inside a Parcel so that you can transport it through the Intent

This tutorial will teach you how to do that
