How to parse nested Objects in android to readable html

I have this code from JSONParser.java
try{
JSONArray postArray = jsonObject.getJSONArray("posts");
// Go through each post
for (int i = 0; i < postArray.length(); i++) {
JSONObject postObject = postArray.getJSONObject(i);
Post post = new Post();
post.setCfs(postObject.getJSONObject("custom_fields").optString("entity", "N/A"));
that displays this
["Some text"]
I want it to display without [" and "]
My Json for that specific part is as below
"posts":[{
"date":"2016-02-10 10:28:42",
"categories":[{}],
"tags":[],
"author":{"name":"admin"},
"custom_fields":{
"ref_number":["ITB NUMBER: ITB\/002\/2016"],
"deadline":["26 February, 2016"],
"entity":["Refugees (xxx)"]
}

It seems that "entity" is array and you should try something like that:
post.setCfs(postObject.getJSONObject("custom_fields").optJSONArray("entity").getString(0));

How to post multiple rows (or a LIST object) to PHP using JSON (Android)

I am creating an android application in which I am using SQLite. I have one table in which I have 5 fields. There are many rows in that table and I want to send all those rows using JSON to my PHP code so I can receive the object and insert it in the MySQL database.
What is the best way to do it. I am using LIST object but don't know how I can use POST it using JSON.
Please guide!
i am using this code
mCursor =db.rawQuery("SELECT * FROM customer", null);
while (mCursor.moveToNext()) {
// In one loop, cursor read one undergraduate all details
// Assume, we also need to see all the details of each and every undergraduate
// What we have to do is in each loop, read all the values, pass them to the POJO class
//and create a ArrayList of undergraduates
customer = new Customer();
customer.CustomerName = mCursor.getString(0).toString();
customer.Phone = mCursor.getString(1).toString();
customer.BrandName = mCursor.getString(2).toString();
customer.City = mCursor.getString(3).toString();
customer.FamilyMembers = mCursor.getString(4).toString();
customerList.add(customer);
}
for (int i = 0; i < customerList.size(); i++)
{
JSONObject row = new JSONObject();
row.put("Customer", customerList.get(i));
json.put(row);
}
Don't know how to post it to PHP code.

You have to iterate through your List and fill an JSONArray with JSONObjects for each row. In the JSONObject you can have the key as your column-name and the value with the type you need.
JSONArray json = new JSONArray();
for (int i = 0; i < list.size(); i++) {
JSONObject row = new JSONObject();
row.put("key1", list.get(i).value1);
...
json.put(row);
}
(not tested). Then you can post the json.toString() to the server and retrieve it in PHP with
$jsonstring = file_get_contents('php://input', true);

Parse JSON string from remote URL in Android

Well I'm new to Android. I'm getting a JSON string from a remote URL.
[{"key":"myString1","val":"myValue1"},{"key":"myString2","val":"myValue2"},{"key":"myString3","val":"myValue3"},{"key":"myString4","val":"myValue4"},{"key":"myString5","val":"myValue5"}]
I just need to parse this JSON string & display all key-val pair. I tried something like below from one of the tutorial.
JSONArray jArray = new JSONArray(str);
json = jArray.getJSONObject(0); //This will take first pair.
But I don't know the syntax for iterating through whole json object. Any help would be appreciated. Thanks in Advance.

There's nothing special in it. You do it like iterating any other array.
Let's say you have two String arrays to be filled with values: String[] mKey, mValue
Reading from JSON array will be like:
for (int i = 0; i < array.length(); i++) {
JSONObject object = array.getJSONObject(i);
mKey[i] = object.getString("key");
mValue[i] = object.getString("val");
}

How to Extract json array within an array in android

I am trying to pass some json encoded data from cakephp to android, I have a problem when passing the data
I use
echo json_encode($todaysdata);
exit();
in CakePhp and when I debug this code in cakephp, I get a result in the browser
[{"status":{"uname":"sibin","pass":"shanu","upid":14}},
{"status": {"uname":"amal","pass":"amalu","upid":14}}
]
I need to extract these two status details seperately in Android
I tried one code in android, it gives result, but result is repeated
I want the result of two status seperately
If anybody know, please help me.

set status value as from current json String :
JSONArray jsonarr = new JSONArray("your json String");
for(int i = 0; i < jsonarr.length(); i++){
JSONObject jsonobj = jsonarr.getJSONObject(i);
// get status JSONObject
JSONObject jsonobjstatus = jsonobj.getJSONObject("status");
// get uname
String str_uname=jsonobjstatus.getString("uname");
// get pass
String str_pass=jsonobjstatus.getString("pass");
// get upid
String str_upid=jsonobjstatus.getString("upid");
}

Try with the following code.
JSONArray jsonArray = new JSONArray("yourJsonResponseInString");
for(int i=0;i<jsonArray.length();i++)
{
JSONObject e = jsonArray.getJSONObject(i);
JSONObject jsonObject = e.getJSONObject("status");
Log.i("=== UserName","::"+jsonObject.getString("uname"));
Log.i("=== Password","::"+jsonObject.getString("pass"));
Log.i("=== UId","::"+jsonObject.getString("upid"));
}

In Android, display Google Places JSON data in a list?

In the below code, I can display the first returned JSON place name result from my Google Places URL. Rather than just the first item, I'd like to display the whole returned list of place names. What would be the easiest way of doing this? Can you point me to a tutorial, or give sample code?
HttpGet get = new HttpGet(bcURL.toString());
HttpResponse r = client.execute(get);
int status = r.getStatusLine().getStatusCode();
if(status == 200){
HttpEntity e = r.getEntity();
String data = EntityUtils.toString(e);
json = new JSONObject(data);
JSONArray timeline = json.getJSONArray("results");
JSONObject lastport = timeline.getJSONObject(0);
return lastport;
}else{
Toast.makeText(NewGPS3.this, "oops", Toast.LENGTH_SHORT);
return null;
}
The line JSONObject lastport = timeline.getJSONObject(0); shows the first name. I'd like to show a list rather than just the first item.

You are going to need to use a JSONArray object in order to get at the array. It should go something like this:
JSONObject entireObject = new JSONObject("your JSON string here");
JSONObject mainObject = entireObject.getJSONObject("photos"); // main object in entire object
JSONArray arrayObject = mainObject.getJSONArray("photo"); // array object in the main object
You can then iterate through this array just like any other:
for (int i = 0; i < arrayObject.length(); i++) {
JSONObject photoData = arrayObject.getJSONObject(i);
String yourString = photoData.getString("id");
}
I got some of this out of Pro Android Media. There is a really good JSON api call example in this book. You can probably get the source code for free, too.

for(int i = 0; i < timeline.size(); i++){
JSONObject lastport = timeline.getJSONObject(i);
//Save the item to a ArrayList and use that list for your ListAdapter.
googlePlaces.add(lastPort);
}
