text view id=hello not showing up.

this code using-

   if(fname!="!")     {         edit.settext("edit");         hello.setvisibility(view.visible);     }     else     {         edit.settext("what's going on?");         hello.setvisibility(view.gone);     } 

change recyclerview , textview attributes - make recyclerview layout_above of textview, not textview below recyclerview.

also layout_alignparentbottom="true" must added textview.

<android.support.v7.widget.recyclerview     android:id="@+id/drawerlist"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:layout_below="@id/nav_header_container"     android:layout_above="@+id/hello"     android:layout_margintop="15dp" />  <textview     android:id="@+id/hello"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:layout_margintop="15dp"     android:paddingleft="5dp"     android:text="hello"     android:layout_alignparentbottom="true"     android:textcolor="#000"     android:textstyle="italic" />
