android - Why it says there's error "No resource found that matches" even though it exists? -

error message

thats b'coz using styles.xml instead of style.xml.

try changing referance follows...

 <textview             style="@styles/behindmenuitemtitle"             android:text="right" /> 

in same way other referances of styles.xml file...
