adapter

big explanation (better safe...), question in bold if you don't want to read it all. Thanks a lot for your help! I have an app with a ListView , and two custom XMLs. One is a single TextView, for the headers. The other has 3 TextViews and 3 ImageViews that represent the data. As most of you know, Jeff Sharkey already has a very clever (imho) solution ( SeparatedListAdapter ), which allows the class to work, without modifications, with ImageViews. Although it accepts String s, I can provide the valueOf of the drawable int resources, and it will figure it out. Great, see code and screen at end

I am trying to display a list of task in this way - Icon | ApplicationName | CheckBox As i found that no listview adapter supports this so i decided to develop a custom adapter but i am unable to fetch the icon of an application. So far i tried this :- public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; View row = inflater.inflate(R.layout.item, parent, false); CheckedTextView ctb = (CheckedTextView)row.findViewById(R.id.checkText); String pkgName = "com.abc.abc"; ctb.setText("bla bla"); ImageView iv = (ImageView)row.findViewById(R.id.image); List

Is it possible to Get the GridLayout items from the Adapter in Android. Like, The items in the GridView come from the ListAdapter associated with this view. Please clarify my doubt.. Thanks Gridlayout doesn't have any Adapters as its not derived from AbsListView . Only GridView comes with Adapters. Yes, it is possible. You don;t say what you are using to create the GridView. Following is an example of getting the data from a cursor when you click on a cell of the grid (and putting it into an intent to call another activity): gridview.setOnItemClickListener(new OnItemClickListener() { public

I am designing a library that has adapters that supports a wide-range of libraries. I want the library to dynamically choose which ever adapter that has the library it uses installed on the machine when importing specific classes. The goal is to be able to change the library that the program depends on without having to make modifications to the code. This particular feature is for handling RabbitMQ connections, as we have had a lot of problems with pika , we want to be able to change to a different library e.g. pyAMPQ or rabbitpy without having to change the underlying code. I was thinking of

In my app, if you click on a button then i want to remove all the listview items. Here, i am using the base adapter for adding the items to the list view. How can i remove the listview items dynamically. mah Call setListAdapter() again. This time with an empty ArrayList. ListView operates based on the underlying data in the Adapter . In order to clear the ListView you need to do two things: Clear the data that you set from adapter. Refresh the view by calling notifyDataSetChanged For example, see the skeleton of SampleAdapter below that extends the BaseAdapter public class SampleAdapter

I have a main activity that creates a ListView and a Custom Adapter . I'm able to populate the ListView if I have the List already created beforehand, but how do I populate it with dynamically fetched data? MainActivity public class MainActivity extends Activity { private ListView myListView; private Context ctx; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.MainActivity); ctx = this; List<Items> myList = new ArrayList<Items>(); myList.add(new Item("Name 1", "Desc 1")); myList.add(new Item("Name 2", "Desc 2")); myList

When creating a customized adapter for ListView in android, I see that I have to create a class the extends ArrayAdapter class and implements the getView(..) method. All of that is OK, but I want to know the sequence of calling methods and executing. i.e. in which point of code the getView() is being called ? From android docs - An Adapter object acts as a bridge between an AdapterView (such as ListView in your case) and the underlying data for that view. The Adapter provides access to the data items and is also responsible for making a View for each item in the data set. So, whenever the

I'm using an extended version of BaseAdapter based on the EfficientAdapter example from the SDK demo samples. My data is basically an object ( ListPlaces ) which holds an ArrayList with the actual list of places, accessible via listPlaces.getValues() . This ArrayList data is sorted by range and the ArrayList consist of some special items (separators), with no data, but a separator flag set to true . Now whenever my EfficientAdapter gets a data object which is a separator it returns false for public boolean isEnabled(int position) and public View getView(int position, View convertView,
