Android - Adjust button height by checkbox height?

Question

I've got a ListView, one row of which contains Button, CheckBox and multiline TextView. The xml layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
               android:layout_width="fill_parent"
               android:layout_height="fill_parent"
               android:layout_centerVertical="true">

    <Button android:id="@+id/open"
              android:layout_height="wrap_content"
              android:layout_width="wrap_content"
              android:src="@drawable/play"
              android:text="Play"
              android:layout_centerVertical="true"
           />

    <CheckBox android:id="@+id/check"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:layout_centerVertical="true"
             android:layout_toRightOf="@id/open"
           />

    <TextView android:text="@+id/label"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:id="@+id/label"
             android:textSize="16px"
             android:layout_toRightOf="@id/check"
             android:paddingLeft="4px"
           />

</RelativeLayout>

You can set custom style to the button with lower padding values then the default one.
You can set margin for the button.
You can set a fixed DP value for the buttons height.

Check out the ALIGN_TOP and ALIGN_BOTTOM properties of relative layout. You can align the top and bottom of your button to the top and bottom of the check box.
