I know you can create a custom Adapter extending BaseAdapter and create various layouts which can be inflated depending on which row the AdapterView is at.. But is there any way to get a simple amount of customization with a SimpleCursorAdapter ? Eg. I have a database and I would like to query it and return the results to a ListView with alternating row layouts. Will SimpleCursorAdapter do? Or are there any elegant solutions for this? Cheers But is there any way to get a simple amount of customization with a SimpleCursorAdapter? Just like BaseAdapter, you can extend CursorAdapter or

I have a view that contains a ListView which is binded to a cursor adapter.

I have a sqlite database in my application. I want to make an expandable list view with that. I am fixed with the approach I should take for that. Tried a lot to find a tutorial for the same, but could not find a single one, where one is populating the Expandable list with the local database. There is this one tutorial in the android site where they are filling the expandable list with the Contact detail in the phone. They are doing this from the content provider ExpandableList2.java So my question is should I also create a content provider for my database which is inside my own application ?

I'm using a SimpleCursorAdapter to display results in a ListView but since I've got to query my database lots of times during a search (using the SearchView widget) it worries me that the cursor might be left opened. This is how I query my database and show the results in a ListView: class SearchCustomers extends AsyncTask<String,Void,Cursor>{ @Override protected Cursor doInBackground(String... params) { //get the query String query=params[0].toLowerCase(Locale.getDefault()); Cursor cursor=mDB.searchCustomersByName((query != null ? query : "@@@@")); return cursor; } @Override protected void

I have 1-50 records in the database. I am fetching those data using cursor and set those values to Spinner using Simple Cursor Adapter. Now what i need is i want to set one value say 39th value as default. But not by its position i want to set by its value. I know how to set the spinner default by its position spinner.setSelection(39) will set the spinner to that value. But i didn't have any idea about setting the spinner default by its value(text) in the database. I know the values in the database. For eg "books" is one of the value in the spinner. I need to set the spinner default as books.

I've also found lots of discussions on how to change the color that's used to highlight an item that is selected. These
