如何在android中创建JSON文件? 我想创建这种看起来像JSON。android动态创建和编辑JSON
{
"contacts": [
{
"id": "c200",
"name": "Ravi Tamada",
"email": "[email protected]",
"address": "xx-xx-xxxx,x - street, x - country",
"gender" : "male",
},
{
"id": "c201",
"name": "Johnny Depp",
"email": "[email protected]",
"address": "xx-xx-xxxx,x - street, x - country",
"gender" : "male",
},
.
.
.
.
] }
嗯,我可以创造一个JSONObjects,但无法弄清楚如何包装,在 “联系人” 阵列。
JSONObject json = new JSONObject();
try {
json.put("id", dataList.get(pos).id);
json.put("name", dataList.get(pos).name);
.
.
.
String jsonString = json.toString();
//and then save it
FileOutputStream fos = mContext.openFileOutput("jsonfile", Context.MODE_PRIVATE);
fos.write(jsonString.getBytes());
fos.close();
当我会读回JSON,我可以编辑JSON,就像从中间删除的JSONObject,末等添加新的项目?
