How to populate spinner from cursorloader?

Question

I have spent days to figure this out but no luck. Wish I could get answer from here. I tried to load data into spinner from my content provider using the cursorLoader method

Answer 1

The problem lies in your construction of the SimpleCursorAdapter, specifically the second and fifth parameters (layout and to). From the docs:

layout: resource identifier of a layout file that defines the views for this list item. The layout file should include at least those named views defined in "to"

to: The views that should display column in the "from" parameter. These should all be TextViews. The first N views in this list are given the values of the first N columns in the from parameter. Can be null if the cursor is not available yet.

So you are correct to use android.R.layout.simple_spinner_item for layout. However, the views passed for to need to be TextViews and contained within android.R.layout.simple_spinner_item: i.e. android.R.id.text1 instead of R.id.spinner1.

In short, use this construction instead:

sAdapter = new SimpleCursorAdapter(
        this,
        android.R.layout.simple_spinner_item,
        null, 
        new String[] {ShopperProvider.TAG_COLUMN_TAG}, 
        new int[] {android.R.id.text1},
        0);
