How to get marathi data from web service which is in .net to spinner?

I am trying it for just another text with yesterdays answers
Just taken one text view and in on create only tried to apply custom font
And the output still not getting Output is like this
current output
See code below
Its showing like this in emulator
{"Get_DepoScheme": [{
"Flag": 1,
"Msg": "Success",
"SchemeId": 1,
"SchemeName": "मुदत ठेव",
"Glid": 55
}, {
"Flag": 1,
"Msg": "Success",
"SchemeId": 2,
"SchemeName": "कर्मचारी भ.नि.नि.मुदत ठेव",
"Glid": 38
}, {
"Flag": 1,
"Msg": "Success",
"SchemeId": 3,
"SchemeName": "सभासद कायम ठेव",
"Glid": 14
}, {
"Flag": 1,
"Msg": "Success",
"SchemeId": 5,
"SchemeName": "आवर्ती ठेव (आर.डी.)",
"Glid": 51
}, {
"Flag": 1,
"Msg": "Success",
"SchemeId": 6,
"SchemeName": "सुकन्या ठेव योजना",
"Glid": 77
}, {
"Flag": 1,
"Msg": "Success",
"SchemeId": 7,
"SchemeName": "स्वामी पेन्शन ठेव योजना",
"Glid": 78
}, {
"Flag": 1,
"Msg": "Success",
"SchemeId": 16,
"SchemeName": "दामदुप्पट ठेव",
"Glid": 54
}]
}

try URLDecoder, for example try this
String flag = URLDecoder.decode(json_data.getString("Flag"), "UTF-8");
and set the text to textview like this
TextView tv = (TextView) findViewById(R.id.tv);
Typeface marathi = Typeface.createFromAsset(getAssets(), "akshar.ttf");
tv.setTypeface(marathi);
tv.setText(flag);
Download the marathi font from here and create an asset folder in your project and add it there.(assets location app>src>main>assets>akshar.ttf)

I want to fetch id and wallet name from the array displayed in array size but i am getting this error.

Your json is wrong, because your walletObject contains this:
{
"wallets": [{
"1": ["Paytm"],
"2": ["Freecharge"],
"3": ["Mobikwik"],
"4": ["PayUmoney"],
"5": ["CitrusCash"],
"6": ["Airtel Money"],
"7": ["Oxigen Wallet"],
"8": ["OLAMoney"],
"9": ["HDFC PayZapp"],
"10": ["Chillr by HDFC"],
"11": ["Pockets by ICICI bank"],
"12": ["JioMoney"],
"13": ["SBI Buddy"],
"14": ["mRupee"],
"15": ["Itzcash"]
}]
}
You got the error because you would like to get the value of id property, but your json doesn't contains id field.
Your json has more problems:
1. send an object instead of array (wallet_array)
2. change your wallet object structure
I think you should use this json structure:
{
"user": [{
"status_code": "1",
"status_desc": "Success",
"user_id": "482",
"id": "26",
"name": "tanmay ",
"pass": "a006b22f887f7d922bafa4c8186ccafd",
"location": "Ahmedabad",
"cards": "ICICI Bank",
"category": "Platinum",
"wallet": "",
"operator": "Vodafone",
"loyaltyProgram": "Any",
"membership": "All Time",
"wallet_array": [{
"id": 1,
"name": "Paytm"
},
{
"id": 2,
"name": "Freecharge"
},
{
"id": 3,
"name": "Mobikwik"
},
{
"id": 4,
"name": "PayUmoney"
},
{
"id": 5,
"name": "CitrusCash"
},
{
"id": 6,
"name": "Airtel Money"
},
{
"id": 7,
"name": "Oxigen Wallet"
},
{
"id": 8,
"name": "OLAMoney"
},
{
"id": 9,
"name": "HDFC PayZapp"
}
]
}]
}

I'm going to guess that you have a JSONArray of person and you want to get the object that has person = John.
If the data is like this
[{
"full_name": "John Smith",
"sex": "male",
"location": "New York, NY, United States"
}, {
"full_name": "Angela Johnson",
"sex": "female",
"location": "San Diego, CA, United States"
}]
You can write:
JSONArray people = new JSONArray(jsondata);
int index = 0;
for (int i = 0; i < people.length(); i++) {
JSONObject tmpObj = people.getJSONObject(i);
string name = tmpObj.getString("full_name");
if (name == "John") {
index = i;
break;
}
}
JSONObject johnObjExample = people.getJSONObject(index);
string johnName = johnObjExample.getString("full_name");
int id = johnObjExample.getInt("id");
String name = johnObjExample.getString("full_name");
String sex = johnObjExample.getString("sex");
String location = johnObjExample.getString("location");

How do I match data by ID's in Android using JSON?

I have two fragments, one shows a program list and one shows a course list. How do I get the selected program from the mainactivity to only show the corresponding course description? They match by ID. Currently, when I click on a program, the whole course list shows up instead of the corresponding course.
