SimpleCursorAdapter可以把我们从Array或数据库中取出的数据绑定的ListView或其他的组件，这个很好用，但有时候有些View，SimpleCursorAdapter并不能直接绑定，需要自己去实现它的setViewBinder方法，下面是我利用SimpleCursorAdapter绑定RatingBar的例子：

SimpleCursorAdapter timeItems = new SimpleCursorAdapter(this,
                R.layout.timeitem_row, timeItemsCursor, from, to);
        timeItems.setViewBinder(new SimpleCursorAdapter.ViewBinder(){

            @Override
            public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
                int rateIndex = cursor.getColumnIndex("rate");
                if(columnIndex == rateIndex)
                {
                    RatingBar ratingBar = (RatingBar)view;
                    ratingBar.setRating(cursor.getInt(rateIndex));
                    return true;
                }
                return false;
            }
        });
