  • SimpleAdapter

    public SimpleAdapter(Context context,
                 List<? extends Map<String,?>> data,
                 int resource,
                 String[] from,
                 int[] to)

    Constructor

    Parameters:

    context - The context where the View associated with this SimpleAdapter is running

    data - A List of Maps. Each entry in the List corresponds to one row in the list. The Maps contain the data for each row, and should include all the entries specified in "from"

    resource - Resource identifier of a view layout that defines the views for this list item. The layout file should include at least those named views defined in "to"

    from - A list of column names that will be added to the Map associated with each item.

    to - The views that should display column in the "from" parameter. These should all be TextViews. The first N views in this list are given the values of the first N columns in the from parameter.

• Method Detail

  • getCount

    public int getCount()

    Description copied from interface: Adapter
    How many items are in the data set represented by this Adapter.

    Specified by:

    getCount in interface Adapter

    Returns:

    Count of items.

    See Also:

    Adapter.getCount()

  • getItem

    public Object getItem(int position)

    Description copied from interface: Adapter
    Get the data item associated with the specified position in the data set.

    Specified by:

    getItem in interface Adapter

    Parameters:

    position - Position of the item whose data we want within the adapter's data set.

    Returns:

    The data at the specified position.

    See Also:

    Adapter.getItem(int)

  • getItemId

    public long getItemId(int position)

    Description copied from interface: Adapter
    Get the row id associated with the specified position in the list.

    Specified by:

    getItemId in interface Adapter

    Parameters:

    position - The position of the item within the adapter's data set whose row id we want.

    Returns:

    The id of the item at the specified position.

    See Also:

    Adapter.getItemId(int)

  • getView

    public View getView(int position,
               View convertView,
               ViewGroup parent)

    Description copied from interface: Adapter
    Get a View that displays the data at the specified position in the data set. You can either create a View manually or inflate it from an XML layout file. When the View is inflated, the parent View (GridView, ListView...) will apply default layout parameters unless you use LayoutInflater.inflate(int, android.view.ViewGroup, boolean) to specify a root view and to prevent attachment to the root.

    Specified by:

    getView in interface Adapter

    Parameters:

    position - The position of the item within the adapter's data set of the item whose view we want.

    convertView - The old view to reuse, if possible. Note: You should check that this view is non-null and of an appropriate type before using. If it is not possible to convert this view to display the correct data, this method can create a new view. Heterogeneous lists can specify their number of view types, so that this View is always of the right type (see Adapter.getViewTypeCount() and Adapter.getItemViewType(int)).

    parent - The parent that this view will eventually be attached to

    Returns:

    A View corresponding to the data at the specified position.

    See Also:

    Adapter.getView(int, View, ViewGroup)

  • setDropDownViewResource

    public void setDropDownViewResource(int resource)

    Sets the layout resource to create the drop down views.

    Parameters:

    resource - the layout resource defining the drop down views

    See Also:

    getDropDownView(int, android.view.View, android.view.ViewGroup)

  • getDropDownView

    public View getDropDownView(int position,
                       View convertView,
                       ViewGroup parent)

    Description copied from interface: SpinnerAdapter

    Get a View that displays in the drop down popup the data at the specified position in the data set.

    Specified by:

    getDropDownView in interface SpinnerAdapter

    Overrides:

    getDropDownView in class BaseAdapter

    Parameters:

    position - index of the item whose view we want.

    convertView - the old view to reuse, if possible. Note: You should check that this view is non-null and of an appropriate type before using. If it is not possible to convert this view to display the correct data, this method can create a new view.

    parent - the parent that this view will eventually be attached to

    Returns:

    a View corresponding to the data at the specified position.

  • getViewBinder

    public SimpleAdapter.ViewBinder getViewBinder()

    Returns the SimpleAdapter.ViewBinder used to bind data to views.

    Returns:

    a ViewBinder or null if the binder does not exist

    See Also:

    setViewBinder(android.widget.SimpleAdapter.ViewBinder)

  • setViewBinder

    public void setViewBinder(SimpleAdapter.ViewBinder viewBinder)

    Sets the binder used to bind data to views.

    Parameters:

    viewBinder - the binder used to bind data to views, can be null to remove the existing binder

    See Also:

    getViewBinder()

  • setViewImage

    public void setViewImage(ImageView v,
                    int value)

    Called by bindView() to set the image for an ImageView but only if there is no existing ViewBinder or if the existing ViewBinder cannot handle binding to an ImageView. This method is called instead of setViewImage(ImageView, String) if the supplied data is an int or Integer.

    Parameters:

    v - ImageView to receive an image

    value - the value retrieved from the data set

    See Also:

    setViewImage(ImageView, String)

  • setViewImage

    public void setViewImage(ImageView v,
                    String value)

    Called by bindView() to set the image for an ImageView but only if there is no existing ViewBinder or if the existing ViewBinder cannot handle binding to an ImageView. By default, the value will be treated as an image resource. If the value cannot be used as an image resource, the value is used as an image Uri. This method is called instead of setViewImage(ImageView, int) if the supplied data is not an int or Integer.

    Parameters:

    v - ImageView to receive an image

    value - the value retrieved from the data set

    This method is usually implemented by Adapter classes.

    Specified by:

    getFilter in interface Filterable

    Returns:

    a filter used to constrain data
