How to change values in second layout in same Activity?

My scenario is that I have a activity which shows the cursor stored in SQLite DB. The main layout contains textview at top and a listview. And then I use simplecursoradapter to populate cursor into listadapter and put listadapter into listview. simplecursoradapter use another layout. The problem now is that when I use simplecursoradapter I bring three columns into listview, example: item name, date and price. That is ok if I don't change these values.

Actually I want to add some string to price and开发者_运维技巧 form new string such as currency sign. According to my understanding we only can setContentView for one layout not two layouts. I also tried to populate a new layout and set value but failed

LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View textEntryView = inflater.inflate(R.layout.itemlist, null); TextView price = (TextView) textEntryView.findViewById(R.id.price); price.setText(currency + c.getString(4).toString());

Even there is no problem in syntax and run apps. But when I run the app and check listview, the price still show price only without adding currency sign. I only can add currency sign under the main layout not the second layout used in simplecursoradapter.

In fact, currency is chosen in user preference, and I use sharedpreference to retrieve its value and add to price value in cursor. It seems that simplecursoradapter is using different layout, so cannot do that.

Does anyone has ideas about this case ?

I would be appreciated if methods and codes are provided for similar approach.

Thanks !!

I'm not sure I follow your question 100%, so this might not be exactly the answer you're looking for.

If you want to have control over how the layout of items look in a list view, you should make your own custom implementation of ArrayAdapter:

A ListAdapter that manages a ListView backed by an array of arbitrary objects. (...) To use something other than TextViews for the array display, for instance, ImageViews, or to have some of data besides toString() results fill the views, override getView(int, View, ViewGroup) to return the type of view you want.

If you just google for custom arrayadapter example, you should find enough examples showing you how to implement this. Two such examples are:

Good luck :)

Finally I used bindview to solve my problem. In my question I already mentioned that I use simplecursoradapter to get data from SQLiteDB not array. I know arrayadapter works but it doesn't work for SQLite efficiently. Before I extended baseadapter to design my own to add custom views on textviews. It works but too slow if there are lots of data. So simplecursoradapter is more efficient.

I extended simplecursoradapter and override bindview for my own purpose. It works for what I need.

Thanks for your help and link for arrayadapter
