enter image description here

solved it! use android:fillviewport="true" , remove linearlayout.

<?xml version="1.0" encoding="utf-8"?> <tabhost xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@android:id/tabhost"     android:layout_width="fill_parent"     android:layout_height="fill_parent">     <linearlayout         android:orientation="vertical"         android:layout_width="fill_parent"         android:layout_height="fill_parent">          <horizontalscrollview             android:id="@+id/horizontalscrollview1"             android:layout_width="fill_parent"             android:layout_height="wrap_content"              android:fillviewport="true">                  <tabwidget                     android:id="@android:id/tabs"                     android:layout_width="fill_parent"                     android:layout_height="wrap_content" >                  </tabwidget>          </horizontalscrollview>          <framelayout             android:id="@android:id/tabcontent"             android:layout_width="fill_parent"             android:layout_height="fill_parent">          </framelayout>      </linearlayout>      <progressbar         android:id="@+id/destinationprogressbar"         style="?android:attr/progressbarstylelarge"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center" />  </tabhost>
