modern ui - Android Metro-Style Design Pattern -

i'm designing metro-style android application.
tiles, groups & scrolls done!

for who're not familiar metro-style (aka modern ui), please take @ following picture.

question :
what's best (performance wise) design pattern sorting tiles dynamically in 2 rows & multiple columns ?

- horizontalscrollview - - linearlayout   - - - every 2 tiles have same weight 

or

- horizontalscrollview - - tablelayout - - - every 2 tiles have same row 

or

- else ? 

try layout:

| relative layout

|--> horizontalscrollview

|--|--> linearlayout (showdivider=middle|beginning|end, , divider drawable=50x1])

|--|--|--> tablelayout (with weight=1)

<relativelayout 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:background="#011a41"     android:paddingbottom="@dimen/activity_vertical_margin" android:paddingleft="@dimen/activity_horizontal_margin" android:paddingright="@dimen/activity_horizontal_margin" android:paddingtop="@dimen/activity_vertical_margin"     tools:context=".main" >      <horizontalscrollview android:id="@+id/horizontalscrollview1"         android:layout_width="match_parent" android:layout_height="match_parent"         android:layout_alignparentleft="true" android:layout_alignparenttop="true" >          <linearlayout android:layout_width="match_parent" android:layout_height="match_parent"             android:orientation="horizontal" android:divider="@drawable/divider"             android:showdividers="middle|beginning|end" >              <tablelayout android:layout_width="wrap_content" android:layout_height="match_parent" >                 <tablerow android:id="@+id/tablerow1" android:layout_width="wrap_content" android:layout_height="wrap_content"                     android:layout_weight="1" >                     <imageview android:id="@+id/imageview1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_launcher" />                 </tablerow>                  <tablerow android:id="@+id/tablerow2" android:layout_width="wrap_content" android:layout_height="wrap_content"                     android:layout_weight="1" >                     <imageview android:id="@+id/imageview2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_launcher" />                 </tablerow>                  <tablerow android:id="@+id/tablerow3" android:layout_width="wrap_content" android:layout_height="wrap_content"                     android:layout_weight="1" >                     <imageview android:id="@+id/imageview3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_launcher" />                 </tablerow>                  <tablerow android:id="@+id/tablerow4" android:layout_width="wrap_content" android:layout_height="wrap_content"                     android:layout_weight="1" >                     <imageview android:id="@+id/imageview4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_launcher" />                 </tablerow>             </tablelayout>              <tablelayout android:layout_width="wrap_content" android:layout_height="match_parent" >                 <tablerow android:id="@+id/tablerow5" android:layout_width="wrap_content" android:layout_height="wrap_content"                     android:layout_weight="1" >                     <progressbar android:id="@+id/progressbar1" android:layout_width="wrap_content" android:layout_height="wrap_content" />                 </tablerow>                  <tablerow android:id="@+id/tablerow6" android:layout_width="wrap_content" android:layout_height="wrap_content"                     android:layout_weight="1" >                     <button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="button" />                 </tablerow>                  <tablerow android:id="@+id/tablerow7" android:layout_width="wrap_content" android:layout_height="wrap_content"                     android:layout_weight="1" >                     <checkbox android:id="@+id/checkbox1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="checkbox" />                 </tablerow>                  <tablerow android:id="@+id/tablerow8" android:layout_width="wrap_content" android:layout_height="wrap_content"                     android:layout_weight="1" >                     <togglebutton android:id="@+id/togglebutton1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="togglebutton" />                 </tablerow>             </tablelayout>         </linearlayout>     </horizontalscrollview> </relativelayout>
