The use of explicit jumps

Two simple layouts:

Main

<LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Xmlns:tools= "Http://schemas.android.com/tools"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"android:orientation= "vertical"Tools:context=". Mainactivity " >    <EditTextAndroid:id= "@+id/et_name"Android:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:hint= "Please enter name:" />    <RadiogroupAndroid:id= "@+id/radiogroup1"Android:layout_width= "Match_parent"Android:layout_height= "Wrap_content"android:orientation= "Horizontal" >        <RadioButtonAndroid:id= "@+id/rb_male"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:text= "Male" />        <RadioButtonAndroid:id= "@+id/rb_female"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:layout_marginleft= "25DP"Android:text= "female" />    </Radiogroup>    <ButtonAndroid:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:onclick= "click"Android:text= "Calculation" /></LinearLayout>
