我正在使用两个 SimpleCursorAdapter 在我的 Listview 中连续显示文本和图像。问题是当两次调用这些适配器时,它们会相互冲突。最后,我的 Listview 只显示了我最后调用的 SimpleCursorAdapter 的数据。
我需要做的是合并这两个 SimpleCursorAdapter,尽管它们使用不同的 sql 数据库。
有什么想法可以解决这个问题??

@Override

setContentView(R.layout.reminder_list);
mDbHelper = new RemindersDbAdapter(this);

mDbHelper.open();
mImageHelper.open();

fillImages();

SimpleCursorAdapter reminders = new SimpleCursorAdapter(this, R.layout.reminder_row, remindersCursor, from, to);

int[] toImage = new int[] {R.id.icon};
// SimpleCursorAdapter which is displayed.
SimpleCursorAdapter images = new SimpleCursorAdapter(this, R.layout.reminder_row, imageCursor, fromImage, toImage);
setListAdapter(images);
