android fragment cannot setvisibility relativelayout -

i usging fragments, , in activity want show/hide relativelayout(the last: xk1) when touch edittext :

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/xmlayout" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/linearborder" > <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/xsublayout" android:keepscreenon="true" android:orientation="vertical" android:layout_below="@+id/rl_boutton" android:layout_width="fill_parent" android:layout_height="fill_parent" > <edittext android:id="@+id/edittext_code_d" android:layout_width="304dp" android:layout_height="wrap_content" android:layout_below="@+id/rl_boutton" android:layout_centerhorizontal="true" android:background="@drawable/plaquehaut" android:ems="4" android:gravity="center_vertical|center_horizontal" android:inputtype="number" android:maxlength="4" android:text="123" android:textsize="80sp" android:focusableintouchmode="true" /> <edittext android:id="@+id/edittext_code_m" android:layout_width="304dp" android:layout_height="wrap_content" android:layout_alignleft="@+id/edittext_code_d" android:layout_below="@+id/edittext_code_d" android:background="@drawable/plaquebas" android:ems="4" android:gravity="center_vertical|center_horizontal" android:inputtype="number" android:maxlength="4" android:text="1337" android:textsize="80sp" /> </relativelayout> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:id="@+id/xk1" android:layout_height="wrap_content" android:orientation="vertical" android:visibility="gone"> <include android:id="@+id/xkeyboard" layout="@layout/keyboard"> </include> </relativelayout> </relativelayout>

here's code:

public view oncreateview(layoutinflater inflater, viewgroup container,bundle savedinstancestate) { view view = inflater.inflate(r.layout.fragment_rsslist_overview,container, false); seek { mlayout = (relativelayout) view.findviewbyid(r.id.xk1); mklayout = (relativelayout) view.findviewbyid(r.id.xkeyboard); } grab (exception e) { log.w(getclass().getname(), e.tostring()); } met = (edittext) view.findviewbyid(r.id.edittext_code_d); met.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { edittext_onclick(v); } }); met1 = (edittext) view.findviewbyid(r.id.edittext_code_m); met1.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { edittext_onclick(v); } }); met.setontouchlistener(this); homecoming view; } public boolean ontouch(view v, motionevent event) { enablekeyboard(); homecoming true; } private void enablekeyboard() { mlayout.setvisibility(relativelayout.visible); mklayout.setvisibility(relativelayout.visible); }

the activity stop when programme run here: mlayout.setvisibility(relativelayout.visible);

how can resolve this?

thx, in advance.

you should define next top view: xmlns:android="http://schemas.android.com/apk/res/android" think why nullpointerexception layoutinflater can't find right view throuh hierachy.
