Add Button_name to String.xml:

<name= "Button_name"> login </string> 

The button references the value of Button_name through @string/button_name:

< Button         Android:id = "@+id/button1"         android:layout_width= "Match_parent"        android:layout_height= "Wrap_ Content "        android:text=" @string/button_name "/>

ImageButton:

< ImageButton         Android:id = "@+id/imagebutton1"         android:layout_width= "Match_parent"        android:layout_height= "Wrap_ Content "        android:src=" @drawable/ic_launcher "/>
