Question

Question: Why there is extra space in 2.3.3?

This is a strange behaviour that is why i thought i should ask. I got a checkbox in my xml and i have a background to set on it. so i put the background in its button property.

like android:button="@drawable/back_checkbox"

where back_checkbox is just a selector having checked/unchecked state

Now in 2.3.3:

And in 4.2:

Try Toggle Button instead.

<ToggleButton
    android:id="@+id/toggleButton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:background="@drawable/your_selector_xml"
    android:textOn=""
    android:textOff="" />
