How to create Cursor from JSONArray?

Question

I have an adapter class which is extending GroupingCursorAdapter and constructor of type Adapter_Contacts(Context context, Cursor cursor, AsyncContactImageLoader asyncContactImageLoader).

I want to use this same class for populating my ListView. I am getting data from one web service which is JSON.

So my question is that, how can I convert a JSONArray to Cursor to use same adapter class?

You can convert that JSONArray to a MatrixCursor:

// I'm assuming that the JSONArray will contain only JSONObjects with the same propertties
MatrixCursor mc = new MatrixCursor(new String[] {"columnName1", "columnName2", /* etc*/}); // properties from the JSONObjects
for (int i = 0; i < jsonArray.length(); i++) {
      JSONObject jo = jsonArray.getJSONObject(i);
      // extract the properties from the JSONObject and use it with the addRow() method below 
      mc.addRow(new Object[] {property1, property2, /* etc*/});
}
