Spinners





Spinners provide a quick way to select one value from a set. In the default state, a spinner shows its currently selected value. Touching the spinner displays a dropdown menu with all other available values, from which the user can select a new one.

<Spinner
    android:id="@+id/planets_spinner"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" />
To populate the spinner with a list of choices, you then need to specify a SpinnerAdapter in your Activity or Fragment source code.

PHP has a total of eight data types which we use to construct our variables − Integers  − are whole numbers, without a decima...
