Next, we create a SimpleCursorAdapter instance passing it the Cursor, an array of columns to display ( adapterCols), and an array of views that the columns should be displayed in ( adapterRowViews). Let’s see an example with ArrayList:ĪrrayAdapter adapter = new ArrayAdapter(this, android.R.layout.simple_spinner_item, planets) ĭisplaying the contents of a Cursor in a Spinner is pretty straightforward.įirst, we perform a query as discussed here, fetching just the Movie title and id ( quer圜ols). We could pass on the data via an ArrayList or an array of objects (for example strings). We use the in-built simple_spinner_dropdown_item layout file provided by the android platform. The setDropDownViewResource method is used to specify the layout file used to represent each item in the dropdown.
The third layout argument passed to the constructor call is basically how the spinner control will look like when a manual selection is made (or the default one is showing up). The createFromResource method allows us to create an ArrayAdapter from the string array resource. specify the layout to use when the list of choices appearsĪtDropDownViewResource(android.R.layout.simple_spinner_dropdown_item) R.anets_array, android.R.layout.simple_spinner_item) create an ArrayAdapter using the string array and a default spinner layoutĪrrayAdapter adapter = ArrayAdapter.createFromResource(this, You can also load a spinner using an adapter for a dynamic source of options using an Adapter: Specify the string array of options in res/values/planets_array.xml ArrayAdapter and CursorAdapter (or SimpleCursorAdapter) are indirect sub classes of SpinnerAdapter. The data used to populate the Spinner can come from various sources but must be provided through a SpinnerAdapter like an ArrayAdapter if the source is an array or a CursorAdapter for result sets from database queries. String value = spinner.getSelectedItem().toString() Spinner spinner = (Spinner) findViewById(R.id.spinner) Get the selected item out a spinner using:
It references to an array resource that will populate the Spinner.Ĭreate a spinner like any view and specify the android:entries attribute to specify the set of options: Dialog mode uses a dialog window for selecting spinner options and DropDown mode uses drop-down anchored to the Spinner for selecting spinner options. This property has two options: Dialog mode and DropDown mode. It defines display mode for spinner options. The prompt to display when the spinner’s dialog is shown. Some important properties of spinner are:
