JSON解析到ListView Android [英] JSON Parsing to ListView Android

问题描述

我在从JSON解析到Android中的Listview时遇到问题.这是JSON数据的示例:

I have a problem to parsing from JSON to Listview in Android. This is an example of data from JSON :

[{
    "area": "Kebon Jeruk",
    "city": "Jakarta"
}, {
    "area": "Puri",
    "city": "Jakarta"
}, {
    "area": "Grogol",
    "city": "Jakarta"
}]

，我想使ListView像这样:

and I want to make ListView like this :

非常感谢您.

推荐答案

JSONArray arr = new JSONArray(yourJSONresponse);
List<String> list = new ArrayList<String>();
for(int i = 0; i < arr.length(); i++){
    String info = arr.getJSONObject(i).getString("area") + arr.getJSONObject(i).getString("city");
    list.add(info);
}

然后将列表转换为字符串数组，然后使用适配器像下面这样填充ListView:

And then just turn the List into an Array of Strings, and use an adapter to fill the ListView like so:

ArrayAdapter adapter = new ArrayAdapter<String>(this,R.layout.ListView,StringArray);
ListView listView = (ListView) findViewById(R.id.listview);
listView.setAdapter(adapter);
