        int id = item.getItemId();
        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

<resources>
    <string name="app_name">sampleRetry</string>
    <string name="hello_world">Hello world!</string>
    <string name="action_settings">Settings</string>
    <string name="Male">male</string>
    <string name="Female">female</string>
    <string name="title_activity_main2">Main2Activity</string>
    <string name="select_branch">Select Trade</string>
    <string-array name="branch">
        <item>CS</item>
        <item>EC</item>
        <item>IT</item>
        <item>EE</item>
    </string-array>
