Android: setOnClickListener for children of RelativeLayout -

i use relativelayout

but children of layout not work settext , click , ...

how fixed ?

code :

imageview imageview01 = (imageview) findviewbyid(r.id.imageview01); if (imageview01 != null) {     imageview01.setonclicklistener(new onclicklistener() {        public void onclick(view arg0) {           log.i("error", "q" + 108);        }    }); } 

this code linearlayout child of relativelayout

xml :

<linearlayout android:id="@+id/lnrvideocontrol" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" >  <imageview     android:id="@+id/imgplayvideo"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_weight="0.5"     android:focusable="false"     android:src="@drawable/play" />  <linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:layout_marginleft="15dp"     android:layout_marginright="15dp"     android:layout_margintop="5dp"     android:layout_weight="0.5"     android:gravity="center" >      <seekbar         android:id="@+id/seekbarvideo"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_marginleft="7dp"         android:layout_margintop="2dp"         android:layout_weight="0.5"         android:paddingleft="8dp"         android:paddingright="8dp"         android:progressdrawable="@drawable/red_scrubber_progress"         android:thumb="@drawable/red_scrubber_control_thin"         android:thumboffset="8dp" /> </linearlayout> 

if use code out of relativelayout worked full !

how fix problem ?

you have imageview id imgplayvideo. creating reference other imageview.

imageview imageview01 = findviewbyid(r.id.imageview01) 

this might wrong reference. correct code , refer exact imageview

imageview imageview = findviewbyid(r.id.imgplayvideo) 

this might fix issue.
