how can in android layout xml? can't find info percentage or positioning that...

thanks folks!

you can use either gridview or simple linearlayout 3 item each row layout weight 1 each column. unlike gridview (or listview), if use linearlayout wont reused when view draw outside screen. here simple using simple linearlayout:

<linearlayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" > <linearlayout     android:id="@+id/row1"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal" >      <button         android:id="@+id/location1"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="1" />      <button         android:id="@+id/location2"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="1"/>     <button         android:id="@+id/location3"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="1"/> </linearlayout> <linearlayout     android:id="@+id/row2"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal" >      <button         android:id="@+id/location4"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="1" />      <button         android:id="@+id/location5"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="1"/>     <button         android:id="@+id/location6"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="1"/> </linearlayout> </linearlayout>
