Divide Layouts into Two Parts Programmatically(without using xml)

For this we just need a class and we will programmatically create the Layouts. And after this we will add Buttons in each layout.

package com.AndroidDevelopmentGuru.progmatic;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.Gravity;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.LinearLayout.LayoutParams;

public class progmmatic extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
       
        //creating a Linear Layout
        LinearLayout parent_layout = new LinearLayout(this);
       

        //Specifying Orientation
        parent_layout.setOrientation(LinearLayout.VERTICAL);
               
        setContentView(parent_layout);
       
       
        //Creating first child
        LinearLayout child_one = new LinearLayout(this);
        LinearLayout.LayoutParams one_params = new      LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,     LayoutParams.MATCH_PARENT,1f);
        child_one.setBackgroundColor(Color.parseColor("#EEFFAA"));
        child_one.setLayoutParams(one_params);
       
        // creating second Child
        LinearLayout child_Second = new LinearLayout(this);
        LinearLayout.LayoutParams second_params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT,1f);
        child_one.setBackgroundColor(Color.parseColor("#FF9999"));
        child_Second.setLayoutParams(second_params);
        second_params.gravity= Gravity.CENTER;       
        child_Second.setOrientation(LinearLayout.VERTICAL);  
       
       
       
        //Adding both child layout into parent layout
                parent_layout.addView(child_one);
                parent_layout.addView(child_Second);
       
               
  Button b1 = new Button(this)
  b1.setLayoutParams(new     LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
        b1.setText("First Progmmatic Button");
       
        child_one.addView(b1);
       
                
        
       
       
        Button b2 = new Button(this);
        b2.setText("Second Progmmatic Button");
        LayoutParams btn_parms = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
        btn_parms.gravity=Gravity.CENTER_HORIZONTAL;
        child_Second.addView(b2, btn_parms);
       
    }   

   
   
}
