您可以使用本网站格式化在你的JSON字符串中一个简单的方法来查看。
Android提供了一个适当的库做你想要的东西。
You can use this website to format your JSON string in a in an easier way to view it. Android provides an appropiate library to do what you want.
这是你需要COM $手册页p $ phend如何使用Android JSON API。
This is the manual page you need to comprehend how to use Android JSON API.
和这里你可以看到一个教程,理解如何解析JSON字符串。
And here you can see a tutorial to understand how to parse JSON string.
{
"glossary": {
"title": "example glossary",
"GlossDiv": {
"title": "S",
"GlossList": {
"GlossEntry": {
"ID": "SGML",
"SortAs": "SGML",
"GlossTerm": "Standard Generalized Markup Language",
"Acronym": "SGML",
"Abbrev": "ISO 8879:1986",
"GlossDef": {
"para": "A meta-markup language, used to create markup languages such as DocBook.",
"GlossSeeAlso": ["GML", "XML"]
},
"GlossSee": "markup"
}
}
}
}
}
如果上面的例子是你的字符串,可以解析它传递给JSONObject的构造器:
If the example above is your string, you can parse it passing it to the JSONObject constructor:
String jsonString = "...."; // the above string
try {
JSONObject obj = new JSONObject(jsonString);
} catch (JSONException e) {
// This exception is thrown if jsonString is not correctly formatted
}
现在,如果你想获得的JSONObject标有GlossList,里面上面的字符串,你可以这样做:
Now, if you want to get the JSONObject labled "GlossList", inside the string above, you can do this:
JSONObject glossList = obj.getJSONObject("glossary").getJSONObject("GlossDiv").getJSONObject("GlossList");
也有另一种可能:你也可以得到一些JSONArray。在我们的例子中,数组GlossSeeAlso:
There is also another possibility: you can also obtain some JSONArray. In our example, the array GlossSeeAlso:
JSONArray glossSee = glossList.getJSONObject("GlossEntry").getJSONObject("GlossDef").getJSONArray("GlossSeeAlso");
要直接拿到这个数组的值,可以使用方法的getString(int i)以
;如果数组的抗衡是一个JSONObject,你可以使用的方法 getJSONObject(int i)以
。您也可以使用该方法的getString(串标贴)
,将直接获得一个JSONObject的字符串:
To get directly a value of this array, you can use the method getString(int i)
; if the contend of the array is a JSONObject, you can use the method getJSONObject(int i)
. You can also use the method getString(String lable)
to get directly a string in a JSONObject:
String title = glossDive.getString("title");
String firstElement = glossSee.getString(0);
