It is very import use common layout for multiple screen if is possible. Now I show you a simple example of use single layout in multiple screen. And also manipulate them.

Let we need to construct this two screen. Here two screen is very similar, except some text. Let's do it by one layout




main.xml
<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
>
<TextView android:id ="@+id/labelA"
   android:layout_width="fill_parent" 
   android:layout_height="wrap_content"
   android:text="Name:"
   android:layout_x="0px"
   android:layout_y="5px"
/>

<EditText android:id="@+id/edtInput"
   android:layout_x="0px"
      android:layout_y="40px"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:inputType="textEmailAddress"
/>

<TextView android:id ="@+id/labelB"
   android:layout_width="fill_parent" 
   android:layout_height="wrap_content"
   android:text="Email:"
   android:layout_x="0px"
   android:layout_y="110px"
/>

<EditText android:id="@+id/edtInputA"
   android:layout_x="0px"
      android:layout_y="150px"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:inputType="textEmailAddress"
/>

<Button android:id ="@+id/btnClick"
   android:layout_width="180px"
   android:layout_height="70px"
   android:text="Open New Screen"
   android:textSize="14px"
   android:layout_x="0px"
      android:layout_y="235px"
/>

</AbsoluteLayout>



MultipleScreenSameLayout.java
package com.example.MultipleScreenSameLayout;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MultipleScreenSameLayout extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        Button b = (Button) findViewById(R.id.btnClick);
  b.setOnClickListener(new View.OnClickListener() {

   public void onClick(View arg0) {
    // here i call new screen;
    Intent i = new Intent(MultipleScreenSameLayout.this,
      NewScreen.class);
    startActivity(i);
   }
  });
    }
}



NewScreen.java
package com.example.MultipleScreenSameLayout;


import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class NewScreen extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        TextView tvB=(TextView) findViewById(R.id.labelB);
        tvB.setText("Address:");
        
        TextView tvA=(TextView) findViewById(R.id.labelA);
        tvA.setText("Location:");
        
        Button b = (Button) findViewById(R.id.btnClick);
        b.setText("Back");
  
  b.setOnClickListener(new View.OnClickListener() {
   public void onClick(View arg0) {
    setResult(RESULT_OK);
    finish();
   }
  });
    }
}
