android - Not possible to click a Button -

i'm having weird issue button being shown on screen, can't click. not onclick event not firing, seems physically not react clicks, if had transparent layer on top of it.

the main activity built on:

public class musiclist extends activity implements onclicklistener { ... @override     public void oncreate(bundle bundle)     {         super.oncreate(bundle);               setcontentview(r.layout.mymusic);         this.mytabhost = (tabhost)this.findviewbyid(r.id.th_set_menu_tabhost);          this.mytabhost.setup();           tabspec ts = mytabhost.newtabspec("tab_tag_1");          ts.setindicator("media item",getresources().getdrawable(r.drawable.music));                       ts.setcontent(r.id.media_item_tab);          try {             relativelayout = (relativelayout) mytabhost.findviewbyid(android.r.id.tabcontent).findviewbyid(r.id.media_item_tab);         } catch (nullpointerexception e) {             log.e(this.getclass().getsimplename(),"layout not correct",e);         }              button button = (button)relativelayout.findviewbyid(r.id.play_button);             // button.setclickable(true);             button.setonclicklistener(this);                     mytabhost.addtab(ts);     }     @override     public void onclick(view v) {         startactivity(new intent(intent.action_view, uri.parse(itemdata.get("item_url"))));     } } 

the layout, shown perfect on screen this:

<?xml version="1.0" encoding="utf-8"?>  <tabhost xmlns:android="http://schemas.android.com/apk/res/android"       android:id="@+id/th_set_menu_tabhost"       android:layout_width="fill_parent"       android:layout_height="fill_parent">       <tabwidget            android:id="@android:id/tabs"            android:layout_width="fill_parent"            android:layout_height="fill_parent"/>      <framelayout            android:id="@android:id/tabcontent"            android:layout_width="fill_parent"            android:layout_height="fill_parent"            android:paddingtop="65px">              <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"                 android:id="@+id/media_item_tab"                 android:layout_width="fill_parent"                 android:layout_height="fill_parent">                 <textview                 android:id="@+id/media_title"                 android:layout_width="fill_parent"                 android:layout_height="wrap_content"                 android:textsize="30sp"                 android:textcolor="#40a5d9"                 android:gravity="center"                 android:layout_alignparenttop="true"                 android:singleline="true"                 android:ellipsize="marquee"                 android:text="title"                 >                 </textview>                 <imageview                 android:id="@+id/media_cover"                 android:layout_width="fill_parent"                 android:layout_height="180px"                 android:gravity="center"                 android:layout_below="@+id/media_title"                 android:src="@drawable/geniocover"                               >                 </imageview>                 <textview                 android:id="@+id/media_author"                 android:layout_width="fill_parent"                 android:layout_height="wrap_content"                 android:textsize="20sp"                 android:textcolor="#86ccf3"                 android:gravity="center"                 android:singleline="true"                 android:ellipsize="marquee"                 android:layout_below="@+id/media_cover"                  android:text="author"                 >                 </textview>                 <textview                 android:id="@+id/media_album"                 android:layout_width="fill_parent"                 android:layout_height="wrap_content"                 android:textsize="18sp"                 android:textcolor="#daffff"                 android:gravity="center"                 android:singleline="true"                 android:ellipsize="marquee"                 android:layout_below="@+id/media_author"                     android:text="album (year)"                 >                 </textview>                 <button                 android:id="@+id/play_button"                 android:layout_width="fill_parent"                 android:layout_height="wrap_content"                 android:text="play"                 android:textcolor="#003983"                 android:textstyle="bold"                 android:textsize="20sp"                 android:gravity="center"                 android:layout_below="@+id/media_album"                 android:clickable="true"                     >                 </button>             </relativelayout>           <listview           android:id = "@+id/tablist"           android:layout_width="fill_parent"            android:layout_height="fill_parent"           />       </framelayout>  </tabhost> 

any suggestions?

thanks!

you have framelayout 2 children when it's intended host one. listview last added, end on top , receiving of input.
