Class RemoteViewsAdapter

    • Method Detail

      • finalize

        protected void finalize()
                         throws Throwable
        Description copied from class: Object
        Invoked when the garbage collector has detected that this instance is no longer reachable. The default implementation does nothing, but this method can be overridden to free resources.

        Note that objects that override finalize are significantly more expensive than objects that don't. Finalizers may be run a long time after the object is no longer reachable, depending on memory pressure, so it's a bad idea to rely on them for cleanup. Note also that finalizers are run on a single VM-wide finalizer thread, so doing blocking work in a finalizer is a bad idea. A finalizer is usually only necessary for a class that has a native peer and needs to call a native method to destroy that peer. Even then, it's better to provide an explicit close method (and implement Closeable), and insist that callers manually dispose of instances. This works well for something like files, but less well for something like a BigInteger where typical calling code would have to deal with lots of temporaries. Unfortunately, code that creates lots of temporaries is the worst kind of code from the point of view of the single finalizer thread.

        If you must use finalizers, consider at least providing your own ReferenceQueue and having your own thread process that queue.

        Unlike constructors, finalizers are not automatically chained. You are responsible for calling super.finalize() yourself.

        Uncaught exceptions thrown by finalizers are ignored and do not terminate the finalizer thread. See Effective Java Item 7, "Avoid finalizers" for more.

      • isDataReady

        public boolean isDataReady()
      • saveRemoteViewsCache

        public void saveRemoteViewsCache()
      • getRemoteViewsServiceIntent

        public Intent getRemoteViewsServiceIntent()
      • 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
        Count of items.
      • 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
        position - Position of the item whose data we want within the adapter's data set.
        The data at the specified position.
      • 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
        position - The position of the item within the adapter's data set whose row id we want.
        The id of the item at the specified position.
      • setVisibleRangeHint

        public void setVisibleRangeHint(int lowerBound,
                               int upperBound)
        This method allows an AdapterView using this Adapter to provide information about which views are currently being displayed. This allows for certain optimizations and preloading which wouldn't otherwise be possible.
      • 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
        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
        A View corresponding to the data at the specified position.
      • hasStableIds

        public boolean hasStableIds()
        Description copied from interface: Adapter
        Indicates whether the item ids are stable across changes to the underlying data.
        Specified by:
        hasStableIds in interface Adapter
        hasStableIds in class BaseAdapter
        True if the same id always refers to the same object.
      • isEmpty

        public boolean isEmpty()
        Specified by:
        isEmpty in interface Adapter
        isEmpty in class BaseAdapter
        true if this adapter doesn't contain any data. This is used to determine whether the empty view should be displayed. A typical implementation will return getCount() == 0 but since getCount() includes the headers and footers, specialized adapters might want a different behavior.
      • notifyDataSetChanged

        public void notifyDataSetChanged()
        Description copied from class: BaseAdapter
        Notifies the attached observers that the underlying data has been changed and any View reflecting the data set should refresh itself.
        notifyDataSetChanged in class BaseAdapter
