android - Layout pushes up when keyboard popups -

whole layout pushes when keyboard pops up. xml file contains listview , below 2 buttons, when keyboard popups both listview , buttons pushes up.

    <?xml version="1.0" encoding="utf-8"?>     <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical"     tools:context="com.example.athis.buy.homescreen">      <searchview         android:layout_width="match_parent"         android:layout_height="wrap_content" />      <listview         android:id="@+id/list_item"         android:layout_width="match_parent"         android:layout_height="0dp"         android:layout_margintop="10dp"         android:layout_weight="8"         android:divider="#ffffff"         android:dividerheight="10dp"         android:padding="5dp" />      <linearlayout         android:id="@+id/buttons"         android:layout_width="match_parent"         android:layout_height="0dp"         android:layout_weight="1"         android:background="#a8b3ff"         android:gravity="bottom"         android:orientation="horizontal"         android:weightsum="100">          <button             android:id="@+id/filter"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_marginend="5dp"             android:layout_marginleft="10dp"             android:layout_marginright="5dp"             android:layout_marginstart="10dp"             android:layout_weight="50"             android:text="filter"             android:layout_marginbottom="2dp"/>          <button             android:id="@+id/sort"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_marginend="10dp"             android:layout_marginleft="5dp"             android:layout_marginright="10dp"             android:layout_marginstart="5dp"             android:layout_weight="50"             android:text="sort"             android:layout_marginbottom="2dp"/>     </linearlayout> </linearlayout> 

i have added android:windowsoftinputmode="statehidden" in manifest when touch edittext keyboard should pop up

add windowsoftinputmode="adjustpan" attribute in androidmanifest.xml particular activity. refer this.

<activity         android:name=".activities.youractivity"         android:label="@string/app_name"         android:screenorientation="portrait"         android:windowsoftinputmode="adjustpan" />
