JSON解析

关于Json解析(org.json.JSONObject)

1. 普通的Json对象

JSONObject jsonObj = new JSONObject("{"c":0,"m":"120","d":"KJSYRMOVMSOEMB==-FNE"}");

Log.i("RedWolf","C= "+jsonObj.getInt("c")+" M= "+jsonObj.getString("m")+" D= "+jsonObj.getString("d"));

2. Json数组

//把指定的Json转换成字符串数组
JSONArray jsonArray = new JSONArray("[{\"name\":\"盖伦\",\"sex\":\"男\",\"r\":\"大宝剑\"},{\"name\":\"蛮王\",\"sex\":\"男\",\"r\":\"野蛮冲撞\"}]");
//第一个里面装的是盖伦 第二个里面装的是蛮王
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = (JSONObject) jsonArray.opt(i);
DebugUtil.LogI("RedWolf", "姓名:" + jsonObject.getString("name") + " 大招:" + jsonObject.getString("r") + " 性别:" + jsonObject.get("sex"));
}

3. Json对象与Json数组相结合

try {
String json = "{\"name\":\"盖伦\",\"sex\":\"男\",\"skill\":[{\"name\":\"审判\",  \"info\":\"无敌风火轮\"},{\"name\":\"德玛西亚正义\",\"info\":\"大宝剑\"}],    \"address\":\"德玛西亚\"}";
// 同样 把字符转变为JsonObject对象
JSONObject jsonObject = new JSONObject(json);
//在这里我们就可以取出我们的姓名,性别和所属势力对不对 各位?
StringBuffer sb = new StringBuffer();
sb.append("姓名:" + jsonObject.getString("name"));
sb.append(" 性别:" + jsonObject.getString("sex"));
sb.append(" 所属势力:" + jsonObject.getString("address"));
//然后我们从这个JsonObject对象中取出我们的JsonArray对象
JSONArray jsonArray = jsonObject.getJSONArray("skill");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObjectSkill = (JSONObject) jsonArray.opt(i);
sb.append(" 技能名:" + jsonObjectSkill.getString("name") + " 技能描述:" + jsonObjectSkill.getString("info"));
}
DebugUtil.LogI("RedWolf", sb.toString());
} catch (JSONException e) {
DebugUtil.LogI("RedWolf","异常"+e);
}

4.综合型

String json = "[{\"name\":\"盖伦\",\"sex\":\"男\",\"skill\":[{\"name\":\"审判\",\"info\":{\"mp\":\"不消耗\",\"type\":\"AD伤害\"}},{\"name\":      \"德玛西亚正义\",\"info\":{\"mp\":\"不消耗\",\"type\":\"魔法伤害，对大反派造成真实伤害\"}}],\"address\":\"德玛西亚\"},{\"name\":\"拉克丝       \",\"sex\":\"女\",\"skill\":[{\"name\":\"光之束缚\",\"info\":{\"mp\":\"消耗\",\"type\":\"AP伤害\"}},{\"name\":\"透光奇点\",\"info\":     {\"mp\":\"消耗\",\"type\":\"AP伤害\"}}],\"address\":\"德玛西亚\"}]";
//由于他的最外部是一个数组,所以 首先 我们需要得到两个JsonArray
//(0)盖伦 {"name":"盖伦","sex":"男","skill":[{"name":"审判","info":{"mp":"不消耗","type":"AD伤害"}},{"name":"德玛西亚正义","info":{"mp":"不消       耗","type":"魔法伤害，对大反派造成真实伤害"}}],"address":"德玛西亚"}
//(1)拉克丝 {"name":"拉克丝","sex":"女","skill":[{"name":"光之束缚","info":{"mp":"消耗","type":"AP伤害"}},{"name":"透光奇点","info":{"mp":"消       耗","type":"AP伤害"}}],"address":"德玛西亚"}
JSONArray jsonArray = new JSONArray(json);
for (int i = 0; i < jsonArray.length(); i++) {
//依次取出
JSONObject jsonObject = (JSONObject) jsonArray.opt(i);
StringBuffer sb = new StringBuffer();
sb.append("姓名:" + jsonObject.getString("name"));
sb.append(" 性别:" + jsonObject.getString("sex"));
sb.append(" 所属势力:" + jsonObject.getString("address"));
//我们还剩下技能没有选择是不是,技能也是一个JSONArray
JSONArray jsonArray1 = jsonObject.getJSONArray("skill");
//我们就得到了(盖伦为例)
//{"name":"审判","info":{"mp":"不消耗","type":"AD伤害"}}
//{"name":"德玛西亚正义","info":{"mp":"不消耗","type":"魔法伤害，对大反派造成真实伤害"}}
for (int i1 = 0; i1 < jsonArray1.length(); i1++) {
JSONObject jsonObject1 = (JSONObject) jsonArray1.opt(i1);
sb.append(" 技能名:" + jsonObject1.getString("name"));
//然后我们发现 技能描述也是一个JsonObject对象,现在我们就已经轻车熟路了吧
JSONObject jsonObject2 = jsonObject1.getJSONObject("info");
//我们就得到了(盖伦为例)
//{"mp":"不消耗","type":"AD伤害"}
sb.append(" 是否耗蓝:" + jsonObject2.getString("mp"));
sb.append(" 伤害类型:" + jsonObject2.getString("type"));
}
DebugUtil.LogI("RedWolf", sb.toString());
sb = new StringBuffer();
}
