SimpleCursorAdapter.ViewBinder-不同地应用于每一行（ListFragment）

Question

In my app, I pull 3 strings from an SQlite database to populate a ListView. In the listrow I have to TextViews and an ImageView.

The two TextViews are currently populated properly(with different text in each row). But, this is not the case for the ImageView, which I set using a ViewBinder. Namely, the image in each row all get the same color. How can i fix this? Do I need to extend SimpleCursorAdapter or something?

String[] from = {DbHelper.NAME, DbHelper.COMMENT, DbHelper.COLOR};
String[] column = {DbHelper.C_ID, DbHelper.NAME, DbHelper.COMMENT, DbHelper.COLOR};
int[] to = {R.id.listitem_title, R.id.listitem_summary, R.id.listitem_color};

Cursor cursor = db.query(DbHelper.TABLE_NAME, column, null, null, null, null, null);

this.adapter = new SimpleCursorAdapter(getActivity(), R.layout.list_item_set, cursor, from, to);

adapter.setViewBinder(new SimpleCursorAdapter.ViewBinder() {
public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
    if (view.getId() == R.id.listitem_color) {

        cursor.moveToFirst();
        String color = "#ffffff";
        while (cursor.moveToNext()) {
        color = cursor.getString(cursor.getColumnIndex(DbHelper.COLOR));
        }
        ((ImageView) view).setBackgroundColor(Color.parseColor(color));
            return true;
        }
        return false;
         }
    });

setListAdapter(adapter);

If you're going to use:

String color = "#ffffff";
while (cursor.moveToNext()) {
    color = cursor.getString(cursor.getColumnIndex(DbHelper.COLOR));
}

this will make the color point to the color present in the last row of the Cursor as you loop through the entire Cursor . Instead you'll want to simply get the color from the Cursor :

String color = "#ffffff";
color = cursor.getString(cursor.getColumnIndex(DbHelper.COLOR));
