Android 读取 json 数据(遍历jsonarray和jsonboject)
public String getJson(){
String jsonString = "{"FLAG":"flag","MESSAGE":"SUCCESS","name":[{"name":"jack"},{"name":"lucy"}]}";//json字符串
try {
JSONObject result = new JSONObject(jsonstring);//转换为JSONObject
int num = result.length();
JSONArray nameList = result.getJSONArray("name");//获取JSONArray
int length = nameList.length();
String aa = "";
for(int i = 0; i < length; i++){//遍历JSONArray
Log.d("debugTest",Integer.toString(i));
JSONObject oj = nameList.getJSONObject(i);
aa = aa + oj.getString("name")+"|";
}
Iterator<?> it = result.keys();
String aa2 = "";
String bb2 = null;
while(it.hasNext()){//遍历JSONObject
bb2 = (String) it.next().toString();
aa2 = aa2 + result.getString(bb2);
}
return aa;
} catch (JSONException e) {
throw new RuntimeException(e);
}
}
