<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/parentLayout"
    android:layout_width="match_parent"

    android:orientation="vertical" >

    <Button
        android:id="@+id/buttonView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Create Edit Text" >
    </Button>
</LinearLayout

Step-2- Create a Activity src/CreateEditText.

import android.app.Activity;
import android.os.Bundle;
import android.text.InputFilter;
import android.text.InputType;
import android.util.TypedValue;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;
public class CreateEditText extends Activity {
    private Button buttonView;
    private LinearLayout parentLayout;
    private int hint=0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.custom_edittext);
        buttonView=(Button)findViewById(R.id.buttonView);
        parentLayout = (LinearLayout)findViewById(R.id.parentLayout);
        buttonView.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                createEditTextView();
            }
        });
    }
    protected void createEditTextView() {
        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams (
        RelativeLayout.LayoutParams.WRAP_CONTENT,
        RelativeLayout.LayoutParams.WRAP_CONTENT);
        params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
        params.setMargins(0,10,0,10);
            EditText edittTxt = new EditText(this);
            int maxLength = 5;
            hint++;
            edittTxt.setHint("editText"+hint);
            edittTxt.setLayoutParams(params);
           // edtTxt.setBackgroundColor(Color.WHITE);
            edittTxt.setInputType(InputType.TYPE_CLASS_TEXT);
            edittTxt.setTextSize(TypedValue.COMPLEX_UNIT_SP,18);
            edittTxt.setId(hint);
            InputFilter[] fArray = new InputFilter[1];
            fArray[0] = new InputFilter.LengthFilter(maxLength);
            edittTxt.setFilters(fArray);
            parentLayout.addView(edittTxt);
    }

Thanks for this sir, it works perfectly.
But is there a way i can add all the children of LinearLayout below the existing one and they will appear just like the way i defined the default and i can still use all the inputs from both layouts to make calculations
Thank you very much
