    I found that:

     android:gravity="fill"
    

    works better than "top". Top wouldn't look right if the checkbox may also end up as only one line.

    • use

      android:gravity="top" it will pin the box on top

    • use

      padding_top="4dp" will adjust Text padding only (without changing box padding from top)

    You can try this code:-

        <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:state_checked="false">
            <layer-list>
                <item android:top="2dp">
                    <bitmap android:gravity="center" android:src="@drawable/checkbox" />
                </item>
            </layer-list>
        </item>
        <item android:state_checked="true">
            <layer-list>
                <item android:top="2dp">
                    <bitmap android:gravity="center" android:src="@drawable/checkboxselected" />
                </item>
            </layer-list>
        </item>
        <item>
            <layer-list>
                <item android:top="2dp">
                    <bitmap android:gravity="center" android:src="@drawable/checkbox" />
                </item>
            </layer-list>
        </item>
    </selector>

    android:gravity="top" will fix the problem:

    <CheckBox android:id="@+id/register_checkbox"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="@string/register_hint"
              android:gravity="top"/>
    

    Note that android:gravity is different than android:layout_gravity.
