IF语句不适用于ListView项目android

Question

ListView is generated from JSON with boolean getExpired . if getExpired() is TRUE , then textColor should be changed. but it set on list position even if == FALSE

Why 1st position is changed, if getExpired is FALSE on this item?

this is my getView

public View getView(int position, View convertView, ViewGroup parent) {

    ColorMatrix matrix = new ColorMatrix();
    matrix.setSaturation(0);
    ColorMatrixColorFilter filter = new ColorMatrixColorFilter(matrix);
        if (item.getExpired()) {
            vh.imageView.setColorFilter(filter);
            vh.profilePhoto.setColorFilter(filter);
            vh.expired.setVisibility(View.VISIBLE);
            vh.username.setTextColor(Color.parseColor("#76808D"));
        }
    return vh.rootView;
}

If you're using the ViewHolder pattern you will be getting recycled views which have already have their views set to a certain state. In short, when using ViewHolder also use an else condition to set your view states how you want them to be.
