推荐答案
您可以设置列表视图行颜色按下面的JSON响应：
You can set listview' row color as per your JSON response below :
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = LayoutInflater.from(context).inflate(R.layout.product_listing_items, null);
holder.propic = (ImageView) convertView.findViewById(R.id.productlist_img);
holder.txtproname = (TextView) convertView.findViewById(R.id.productlist_name);
holder.txtprice = (TextView) convertView.findViewById(R.id.productlist_price);
// holder.txtpr = (TextView) convertView.findViewById(R.id.productlist_name);
convertView.setTag(holder);
}else{
**Add you code here for color.**
view.setBackgroundColor(listData.get(position).get(INTEREST_ACCEPT_COLOR));
holder = (ViewHolder) convertView.getTag();
}
holder.txtproname.setText(listData.get(position).get(TAG_NAME));
holder.txtprice.setText(listData.get(position).get(TAG_PRICE));
aQuery.id(holder.propic).image(listData.get(position).get(TAG_IMAGE),true,true,0,R.drawable.meracaslogo);
// image parameter : 1 : memory cache,2:file cache,3:target width,4:fallback image
return convertView;
}
编辑：
有关展示给你的TextView的颜色，你应该首先把所有的颜色HashMap和HashMap的是传递给您的适配器。
For showing colors to your TextView , you should first put all the colors in Hashmap and pass that hashmap to your adapter.
现在键可以设置颜色为你的TextView的基础上。
Now on the basis of keys you can set colors to your Textview.
HashMap<String, String> hashmap;
传递的Hashmap的ArrayList中的方法。
Method for passing Hashmap in ArrayList.
public ArrayList<HashMap<String, String>> getAllColor(String firstcolor , String second color , String thirdcolor)
{
ArrayList<HashMap<String, String>> array_list = new ArrayList<HashMap<String, String>>();
hashmap = new HashMap<String, String>();
hashmap.put("firstcolor", firstcolor);
hashmap.put("second color",secondcolor);
hashmap.put("thirdcolor",thirdcolor);
array_list.add(hashmap);
}
return array_list;
}
现在呼吁通过你的颜色此方法。并通过您的ArrayList到您的适配器。。和getView（）方法，你可以像下面的键检索：
Now Call this method for passing your colors. And pass your Arraylist to your ADAPTER .. And In getView() method you can retrieve it by keys like below :
**的ArrayList＆LT;＆HashMap的LT;字符串，字符串＆GT;＆GT; ArrayList的** //声明全局
的ArrayList =你的adapterList; //声明适配器的构造
arrayList = "Your adapterList"; // declare in adapter's constructor
在getView（）：
in getView() :
if (arrayList.size() != 0)
{
for (int i = 0; i < arrayList.size(); i++)
{
textView1.setBackgroundColor(arrayList.get(i).get("firstcolor"));
textView2.setBackgroundColor(arrayList.get(i).get("secondcolor"));
textView3.setBackgroundColor(arrayList.get(i).get("thirdcolor"));
}
}
希望这个时候就会解决你的问题。
Hope this time it will solve your problem.
