Question

I am trying to consume PHP Web service with JSON in android

I got response data from server as

How should i parse it to show it on a ListView.I am familiar about how to show data on ListView by creating custom adapter but I am unable to parse this output.Please help

I followed this tutorial to access PHP Web Service

Give me some reference.
Any help is appreciated.
Thank you…

Alos I would like to know what is the proper format of JSONArray generated at php side ??

It is valid but weird json response.
When you parse this json you will get 27 values.
14, samsung, 1, 15, nokia…
But it seems every 3 item is an object like
“14,samsung,1”
“15,nokia,1”.
And that json doesn’t reflect that.

With an online json parser like this, you can see what result you can:

And you can parse that json like this:

List<String> list = new ArrayList<String>();
int counter = 0;
boolean first = true;
String json = "[\"14\",\"Samsung\",\"1\",\"15\",\"Nokia\",\"1\",\"16\",\"Sony Ericson\",\"1\",\"18\",\"LG\",\"1\",\"19\",\"Iphone\",\"1\",\"21\",\"HTC\",\"1\",\"22\",\"Motorola\",\"1\",\"23\",\"Micromax\",\"1\",\"41\",\"BlackBerry\",\"1\"]";
JSONArray getJSONArray;
try {
  getJSONArray = new JSONArray(json);

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

    Log.d("", getJSONArray.getString(i) + "-" + i % 1 + "-" + i % 2);

    if ((first == true && counter == 1) || (first == false && counter == 2)) {
      list.add(getJSONArray.getString(i));
      counter = 0;
      first = false;
    }
    else {
      counter += 1;
    }
  }
}
catch (JSONException e) {
  e.printStackTrace();
}

Log your array to see what you got:

for (String item : list) {
  Log.d("list", item);
}

Results:

D/list    ( 1669): Samsung
D/list    ( 1669): Nokia
D/list    ( 1669): Sony Ericson
D/list    ( 1669): LG
D/list    ( 1669): Iphone
D/list    ( 1669): HTC
D/list    ( 1669): Motorola
D/list    ( 1669): Micromax
D/list    ( 1669): BlackBerry

And for the server site:

Normally that json had to be like this..

[
    {
        id: "14",
        brand: "Samsung",
        status: "1"
    },
    {
        id: "15",
        brand: "Nokia",
        status: "1"
    },
    {
        id: "16",
        brand: "Sony Ericson",
        status: "1"
    }
]
