RelativeLayout : android:layout_height has no effect -

for reason android:layout_height="200sp" attribute not have effect. preview gets drawn correctly in android studio if run app list items not changing size according android:layout_height="200sp". using relativelayout list item listview.

any suggestions?

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="120dip"     android:background="#ffffff"     >      <imageview         android:id="@+id/icon"         android:src="@drawable/ic_launcher"          android:layout_width="50dip"         android:layout_height="50dip"         android:layout_alignparentbottom="true"         android:layout_alignparenttop="true"         android:layout_gravity="center"          />  </relativelayout> 

@edit:

i've made simpler example. assume list items 120dip in height , got icon on left side 50x50 dip in size. reality list items have same height imageview reason.

public view getview(int position, view convertview, viewgroup parent) {     // todo auto-generated method stub     viewholder holder;     if(convertview == null){         convertview = minflater.inflate(r.layout.listview_nearbylist_item, null);         holder = new viewholder();         //holder.text1 = (textview) convertview.findviewbyid(r.id.text1);         //holder.text2 = (textview) convertview.findviewbyid(r.id.text2);         //holder.text3 = (textview) convertview.findviewbyid(r.id.text3);          convertview.settag(holder);     } else {         holder = (viewholder) convertview.gettag();     }      //holder.text1.settext(items.get(position).getrestaurantname());     //holder.text2.settext(items.get(position).getrestaurantgenre());     //holder.text3.settext("08:00 - 18:00 uhr");      return convertview; } 

convertview = minflater.inflate(r.layout.listview_nearbylist_item, null); 

you have 2 problems here:

1. i don't know minflater comes from, please getlayoutinflater() called on activity, not other source. otherwise, themes won't work.

2. use inflate(r.layout.listview_nearbylist_item, parent, false), may fix height problem, , if nothing else avoid other problems rows based on relativelayout.
