android - ResourceNotFoundException though there is a resource -

i'm trying create spinner non-selectable text displayed when dropdown not displayed "--select option--". have created custom spinner adapter , layout file textview "--select option--" using second answer of so post.

i'm getting 6912-6912/com.examp.three e/androidruntime﹕ fatal exception: main android.content.res.resources$notfoundexception: resource id #0x7f04004e exception though have passed layout file constructor.

what doing wrong?

i debugged app , value getnothingselectedlayout 2130968654. kept break point @ return layoutinflater.inflate(nothingselectedlayout, parent, false);. value of getnothingselectedlayout still same. after point, when press f8, goes choreographer.class before crashing

like @kumar ranjan said in comments of answer, checked r.javaclass resource id error log said not there. found id assigned support_simple_spinner_dropdown_item in r.java file. found resource id #0x7f04004e shown in error log in r.java file

here's code:

    arrayadapter<string> adapterbankname = new arrayadapter             (checkamountactivity.this, android.r.layout.simple_spinner_dropdown_item, paymentmode) {         public view getdropdownview(int position, view convertview, viewgroup parent) {              view v = super.getdropdownview(position, convertview, parent);             ((textview) v).setgravity(gravity.center);             ((textview) v).settextcolor(color.black);              return v;          }     };      spinnerbankname.setadapter(new ndspinner(adapterbankname, r.layout.spinnertitle, getapplicationcontext())); //the constructor of ndspinner class 

this ndspinner class:
