How to hide listview dividers dynamically?

Question

I have this ListView whose items i'd like to hide depending on the selection of a RadioGroup. Currently I'm passing a boolean to the ListAdapter due to the RadioGroup having only two options. My items contain a checkbox and i want to either show the entire list or just the ones with the check boxes checked. I'm succeeding at hiding the items but the dividers still show, how can i fix this?

Look how it looks like

(I'm new, so i can't upload images here)

The xml for my row would be:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="1dip" android:gravity="center_vertical" android:background="#FFF"> <CheckBox android:id="@+id/dispositivo_tv" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="#000000" android:textSize="15dip" android:layout_alignParentLeft="true" /> <LinearLayout android:id="@+id/botones" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_alignParentRight="true" android:gravity="center_vertical"> <ImageButton android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/button_foto" android:src="@drawable/camera" android:background="#FFF" android:paddingRight="15dip" android:visibility="invisible"></ImageButton> <ImageButton android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/button_comentario" android:src="@drawable/comment_add" android:background="#FFF" android:paddingRight="15dip"></ImageButton> </LinearLayout> </RelativeLayout>

and the xml block for the ListView would be:

<LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal" android:padding="5dip" android:background="@layout/list_box"> <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="wrap_content" android:cacheColorHint="#00000000" android:headerDividersEnabled="false" android:footerDividersEnabled="false </ListView> </LinearLayout>

and what i use to hide the row when the boolean i told you about is set FALSE is:

wrapper.getDispositivo().setVisibility(View.GONE); wrapper.getFoto().setVisibility(View.GONE); wrapper.getComentario().setVisibility(View.GONE);

PS: wrapper is the instance of the class where i have all the elements of the row, i.e. the checkbox (getDispositivo()), and a couple of image buttons (getFoto(), getComentario())

Thanks in advance...

How about using custom dividers in your relative layout and setDivider(null); so once you hide the layout the dividers are hidden as well. I wanted to actually add this as a comment. But it comes only after 50 reps so had to put it as a answer.

i mean something like a <View layout:alignParentBottom /> in the <RelativeLayout />

Actually I resolve this by using Android filters, thanks for your answer anyway.
