Apply menu at the bottom of your desired layout file as per following :
You have to give bottom margin as per your menu height.

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="@drawable/effect_message_background"    android:orientation="vertical" >    <ScrollView        android:layout_width="fill_parent"        android:layout_height="fill_parent" >    </ScrollView>    <RelativeLayout        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_marginTop="-60dip"        android:gravity="bottom" >        <include layout="@layout/menu_example" />    </RelativeLayout></LinearLayout>

apply following code to slide up and down.

LinearLayout lyl_Menu = = (LinearLayout)findViewById(R.id.lylMenu);@Override    public boolean onKeyDown(int keyCode, KeyEvent event)    {        try        {            if(keyCode == KeyEvent.KEYCODE_MENU)            {                //System.out.println("MENU PRESSED...........");                if(lyl_Menu.isShown())                {                    goneFooter();                }                else                {                    visibleFooter();                }            }            else if(keyCode == KeyEvent.KEYCODE_BACK)            {                if(lyl_Menu.isShown())                {                    goneFooter();                    return true;                }            }        }        catch (Exception e)        {            e.printStackTrace();        }        return super.onKeyDown(keyCode, event);    }    public void visibleFooter()    {        if(!lyl_Menu.isShown())        {            lyl_Menu.setVisibility(View.VISIBLE);            lyl_Menu.startAnimation(AnimationUtils.loadAnimation(UserData.this, R.anim.slide_up_in));        }    }    public void goneFooter()    {        if(lyl_Menu.isShown())        {            lyl_Menu.startAnimation(AnimationUtils.loadAnimation(UserData.this, R.anim.slide_up_out));            lyl_Menu.setVisibility(View.INVISIBLE);        }    }

Make anim folder in res folder e.g. res/anim put following to animation xml files in anim folder :

1) slide_up_in.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" >    <translate        android:duration="300"        android:fromYDelta="100%p"        android:toYDelta="0%p" /></set>

2) slide_up_out.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" >    <translate        android:duration="300"        android:fromYDelta="0%p"        android:toYDelta="100%p" /></set>
