How would I parse an array like the following in Android?
[
5,
10,
15,
20
]
As you can see, there is no key defining the array, like other example arrays have, such as this:
{
"items": [
5,
10,
15
]
}
For the second array, I can easily make a JSONObject and just use:
JSONArray itemArray = jsonObject.getJSONArray("items")
But, as is obvious, there is no key for the first array. So how would one go about this? Is it even possible with standard Android libraries?
Have you tried doing this?
try {
// jsonString is a string variable that holds the JSON
JSONArray itemArray=new JSONArray(jsonString);
for (int i = 0; i < itemArray.length(); i++) {
int value=itemArray.getInt(i);
Log.e("json", i+"="+value);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONArray would just be set to the JSON file that I am getting?
JSONArray itemArray=new JSONArray(yourstringname); where yourstringname is a String variable that holds your JSON file(I'm assuming it's a string) and then the rest will be the same.Consider Foreach version:
try {
JSONArray itemArray=jsonObject.getJSONArray("items");
for (var item : itemArray) {
System.out.println(item);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Here you can directly access the data in json array.
JSONArray itemArray = jsonObject.getJSONArray("items");
for(int i=0;i<itemarray.length;i++)
{
int i = Integer.ParseInt(itemarray.get(i));
Log.i("Value is:::",""+i);
}
