我的代码是这样的
JSONObject object = new JSONObject(result);
JSONArray no1 = object.getJSONArray("relationship_list");
JSONArray no = object.getJSONArray("entry_list");
for(int j=0;j<no.length();j++){
JSONObject obj = no.getJSONObject(j);
JSONObject namevalue = obj.getJSONObject("name_value_list");
JSONObject objid = namevalue.getJSONObject("remind_date_c");
String remaindmeon= objid.getString("value");
JSONObject objname = namevalue.getJSONObject("status_c");
String status1= objname.getString("value");
Spanned status = Html.fromHtml( status1 );
JSONObject objqua = namevalue.getJSONObject("description");
String description = objqua.getString("value");
Log.v("description",""+description);
/*JSONObject objunit = namevalue.getJSONObject("unit_price_c");
String unitprice = objunit.getString("value");
unitprice = unitprice.split("\\.")[0];
JSONObject objtotal = namevalue.getJSONObject("total_price_c");
String totalprice = objtotal.getString("value");
totalprice = totalprice.split("\\.")[0];
JSONObject objdes = namevalue.getJSONObject("description");
String description = objdes.getString("value");*/
JSONObject objrel = no1.getJSONObject(j);
Log.v("objrel",""+objrel);
if(objrel.isNull("link_list") == true){
JSONArray link = objrel.getJSONArray("link_list");
JSONObject objlink = link.getJSONObject(0);
JSONArray records = objlink.getJSONArray("records");
JSONObject objrecords = records.getJSONObject(0);
Log.v("objrecords",""+objrecords);
JSONObject objlinkvalue = objrecords.getJSONObject("link_value");
JSONObject objlinkname = objlinkvalue.getJSONObject("name");
orderno = objlinkname.getString("value");
JSONObject objlinkid = objlinkvalue.getJSONObject("id");
orderid = objlinkid.getString("value");
}
答案 0 :(得分:0)
我猜你应该在这里测试空数组:
JSONArray link = objrel.getJSONArray("link_list");
If (!link.isNull() && link.length>0) {
JSONObject objlink = link.getJSONObject(0);
}
答案 1 :(得分:0)
此检查
if(objrel.isNull("link_list") == true)
应该是
if(!objrel.isNull("link_list"))
