<? XML version= "1.0" encoding= "Utf-8" ?> <  xmlns:android= "Http://schemas.android.com/apk/res/android"
Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"android:layout_gravity= "Center"Android:usedefaultmargins= "true"Android:columncount= "4"    >        <ButtonAndroid:text= "@string/zero"Android:background= "#DFDFDF"android:textsize= "30SP"Android:layout_columnspan= "4"android:gravity= "Center_vertical|right"Android:paddingright= "8DP"android:layout_gravity= "Fill"android:clickable= "false"        />        <ButtonAndroid:text= "@string/clear"Android:layout_columnspan= "3"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/divide"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/one"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/two"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/three"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/multiply"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/four"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/five"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/six"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/sub"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/seven"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/eight"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/nine"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/add"Android:layout_rowspan= "3"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/zero"Android:layout_columnspan= "2"android:layout_gravity= "Fill"        />    <ButtonAndroid:text= "@string/dot"android:layout_gravity= "Fill"        />                       <ButtonAndroid:text= "@string/equal"Android:layout_columnspan= "3"android:layout_gravity= "Fill"        />        </GridLayout>

Where the string file is Res/values/string.xml:

<?XML version= "1.0" encoding= "Utf-8"?><Resources>    <stringname= "App_name">My Second App</string>    <stringname= "Hello_world">Hello world!</string>    <stringname= "Action_settings">Settings</string>    <stringname= "Str_hello">Hello, Android!</string>    <stringname= "Calc_title">Calculator</string>    <stringname= "Zero">0</string>    <stringname= "One">1</string>    <stringname= "both">2</string>    <stringname= "three">3</string>    <stringname= "Four">4</string>    <stringname= "Five">5</string>    <stringname= "Six">6</string>    <stringname= "Seven">7</string>    <stringname= "Eight">8</string>    <stringname= "Nine">9</string>    <stringname= "dot">.</string>    <stringname= "Add">+</string>    <stringname= "Sub">-</string>    <stringname= "Multiply">*</string>    <stringname= "Divide">/</string>    <stringname= "equal">=</string>    <stringname= "Clear">C</string></Resources>
