        for(int x = 0; x < runs.size(); x++){          inflater = getlayoutinflater();         view layout = inflater.inflate(r.layout.run_layout, (viewgroup) getcurrentfocus());          textview name = (textview) layout.findviewbyid(r.id.tvrunname);         name.settext(runs.get(x).getname());          llruns.addview(layout);     } 

heres run_layout xml....

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" android:background="@drawable/run_background" >  <textview     android:id="@+id/tvrunname"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:textcolor="@android:color/white"     android:textappearance="?android:attr/textappearancemedium"     android:layout_gravity="center"     android:layout_margintop="10dp" /> 

here's activities xml....

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".yourruns" android:background="#181818" android:id="@+id/llyourrunslayout">  <scrollview     android:id="@+id/svruns"     android:layout_width="match_parent"     android:layout_height="match_parent" >      <linearlayout         android:id="@+id/llruns"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:orientation="vertical" >       </linearlayout>  </scrollview> 

change (viewgroup) getcurrentfocus() null, becouse inflater.inflate() second parameter parent of view, , when start activity default no elements focus. , indicate 2 parents view first on inflate, second when add layout llruns.

for(int x = 0; x < runs.size(); x++){      inflater = getlayoutinflater();     view layout = inflater.inflate(r.layout.run_layout, (viewgroup) getcurrentfocus());      textview name = (textview) layout.findviewbyid(r.id.tvrunname);     name.settext(runs.get(x).getname());      llruns.addview(layout); }
