setBackgroundColor(ListView) 依赖于数据

Question

我将创建一个动态 ListView 来显示来自 json 服务器的数据。我想让 setBakgroundColor 依赖于数据中的某个对象。例如： json 是

{"Order":[{"id":1,
"situation":"notchecked",
"status":"Processing"},
{"id":2,
"situation":"checked",
"status":"Processing"}]}

如果情况 == 未检查

convertView.setBackgroundColor(Color.GREEN);

这是我在 BaseAdapter 中的视图

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub

        if (convertView == null) {
            convertView = inflater.inflate(R.layout.complete_order_row, parent,
                    false);
                if ()......{

                convertView.setBackgroundColor(Color.GREEN);
                 }
        }


        TextView situation = (TextView) convertView
                .findViewById(R.id.situation);
        situation.setText(catList.get(position).getSituation());
         TextView status= (TextView) convertView
                .findViewById(R.id.status);
        status.setText(catList.get(position).getStatus());
         TextView id= (TextView) convertView
                .findViewById(R.id.id);
        id.setText(catList.get(position).getId));

        return convertView;

    }

你几乎做对了，但每次都需要设置它，无论是在回收还是不回收 convertView 时：

    if (convertView == null) {
        convertView = inflater.inflate(R.layout.complete_order_row, parent,
                false);
       //...
    }
    TextView situation = (TextView) convertView
            .findViewById(R.id.situation);
    situation.setText(catList.get(position).getSituation());
    if (catList.get(position).getSituation().equals("notchecked")) {
       convertView.setBackgroundColor(Color.GREEN);
    } else {
       convertView.setBackgroundColor(Color.BLUE);
    }
