when android soft input make your et push up , how can I to make the view visible below et?

I have a edittext and a button which is below the editext in a layout.

layout xml may like this :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="110dp"
        android:ems="10" >

    </EditText>

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/editText1"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="91dp"
        android:text="Button" />

</RelativeLayout>

the layout 's activity in androidmanifast is:

      android:name="com....activity.CaptureActivity"
        android:windowSoftInputMode="adjustPan" 

so , question is :

when I click or make focus on edittext , the soft input will automatically push up , and it just blocked/covered my button , I want to make button visible. how can I make the button up right the soft input keyborad when input coming up.

could someone give me some advise? thanks.

android:windowSoftInputMode="adjustPan|stateAlwaysHidden"
