Android之解析Android Map地图返回的Json数据

先上一下需要解析的Json数据：

{
"results" : [
{
"address_components" : [
{
"long_name" : "荔湾区",
"short_name" : "荔湾区",
"types" : [ "sublocality", "political" ]
},
{
"long_name" : "广州",
"short_name" : "广州",
"types" : [ "locality", "political" ]
},
{
"long_name" : "广东省",
"short_name" : "广东省",
"types" : [ "administrative_area_level_1", "political" ]
},
{
"long_name" : "中国",
"short_name" : "CN",
"types" : [ "country", "political" ]
}
],
"formatted_address" : "中国广东省广州荔湾区",
"geometry" : {
"bounds" : {
"northeast" : {
"lat" : 23.15961330,
"lng" : 113.2768870
},
"southwest" : {
"lat" : 23.04186250,
"lng" : 113.17712080
}
},
"location" : {
"lat" : 23.1259510,
"lng" : 113.2442380
},
"location_type" : "APPROXIMATE",
"viewport" : {
"northeast" : {
"lat" : 23.16699020,
"lng" : 113.30826770
},
"southwest" : {
"lat" : 23.08489920,
"lng" : 113.18020830
}
}
},
"types" : [ "sublocality", "political" ]
}
],
"status" : "OK"

}

上关键代码： 这只是解析了部分，但是其他部分都一样，不要忘记导入gson-2.1.jar包到程序中



public void parserJson(String str){

try {

JSONObject jsonObject = new JSONObject(str);

//解析了最简单的status

//String s = jsonObject.getString("status");

JSONArray jsonArray = jsonObject.getJSONArray("results");

for(int i=0;i<jsonArray.length();i++){

//输入了formatted_address

s = jsonArray.getJSONObject(i).getString("formatted_address");

System.out.println("formatted_address=======>"+s);

//输出了location里面的lat和lng两个值

double s1 = jsonArray.getJSONObject(i).getJSONObject("geometry").getJSONObject("location").getDouble("lat");

double s2 = jsonArray.getJSONObject(i).getJSONObject("geometry").getJSONObject("location").getDouble("lng");

System.out.println("lat:"+s1 + "-----" + "lng:"+s2);



JSONArray jsonArray2 = jsonArray.getJSONObject(i).getJSONArray("address_components");

for(int j=0;j<jsonArray2.length();j++){

//输出每一个long_name

s = jsonArray2.getJSONObject(j).getString("long_name");

System.out.println(s);

//输出address_components里面的types

JSONArray jsonArray3 = jsonArray2.getJSONObject(j).getJSONArray("types");

for(int k=0;k<jsonArray3.length();k++){

System.out.println(jsonArray3.get(k));

}

}

}



} catch (JSONException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}
}
