Android :: Soft Keyboard Pushes Layout Of Activity Out Of Screen

My activity's layout is as shown below.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">

<FrameLayout android:id="@+id/title_bar"
android:layout_width="fill_parent"
android:layout_height="25dip"
android:background="@drawable/bg_title" />..............

So, the search box is fixed to the bottom of the screen. But, when user clicks the EditText, Soft Keyboard shows up and pushes the layout out of the screen except the search box. I'm just starting out with Android, so am I doing anything wrong here??
