How to update a custom variable in BaseAdapter?

Question

In Android, I have write a class

public class ImageAdapter extends BaseAdapter {

    private Context context;
    private Cursor imageCursor;

    public ImageAdapter(Context context, Cursor imageCursor) {
        this.context = context;
        this.imageCursor = imageCursor;
    }
}

In this code, I want to update value of imageCursor variable when I call notifyDataSetChanged() method. How I can do it?

Answer 1

You can either override notifyDatasetChanged() and put your code before you call super.notifyDatasetChanged, or create a custom method like this,

public void updateNotifyDatasetChanged(Cursor newImageCursor){
    this.imageCursor = newImageCursor;
    notifyDatasetChanged();
}
