How to print image that is in byte array using json - android

i am developing an app,in that i am calling services using json. In that whatever string data is there i am displaying it using textView. But i want to display image that is in byte array.Below is my code:
t1 = (TextView) findViewById(R.id.t1);
i = (ImageView) findViewById(R.id.imageview);
String url = "url"
AQuery mAQuery = new AQuery(MainActivity.this);
mAQuery.ajax(url, String.class, new AjaxCallback<String>() {
#Override
public void callback(String url, String data, AjaxStatus status) {
super.callback(url, data, status);
if (android.support.v7.appcompat.BuildConfig.DEBUG) {
Log.d("###$Request URL", url + "");
Log.d("###$Response ", data + "");
Log.d("###$Status Message : ", status.getMessage() + "");
Log.d("###$Status Code : ", status.getCode() + "");
}
if (status.getCode() != -101) {
String StringData = "" + data;
try {
JSONObject json = new JSONObject(StringData);
int sd;
sd = json.getInt("Stu_id");
String Name = json.getString("Stu_FName");
String LastName = json.getString("Stu_LName");
String Degree = json.getString("DegreeName");
t1.setText("Details OF STUDENTS");
t1.setText( "First Name: " + Name + "\n" + "Last Name:" + LastName + "\n" + "Degree: " + Degree);
} catch (JSONException e) {
}
} else {
}
}
});
}
}
I am not getting how to do that.I am getting data from server like this:

Parse your byte array Image from your json to a byte array variable.
Convert your byte array to bitmap like below
Bitmap bmap = BitmapFactory.decodeByteArray(image, 0, image.length); // image is your byte array
Set the bitmap bmap to an ImageView
imageView.setImageBitmap(bmap);
Update
Try this:
a. Get your byte array like this
JsonArray arr = json.getJSONArray("Image");
b. Create byte array object with size of your Json array arr
byte[] imageArr = new byte[arr.length()];
c. Iterate to insert elements into your byte array
for(int i = 0; i < arr.length(); i++){
imageArr[i] = arr.getInt(i);
}
Then follow the steps 1 and 2 to achieve your goal.

I am using the andriod volley library to get some array of data i want to convert the data into a string but when i tried doing this am only able to get the last data in the array when they are up to ten names only the last name is been converted to string.Here is the code i am using i want to get all the name in as string separated by comma
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
response -> {
try {
JSONArray jsonArray = response.getJSONArray("users");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
String name = jsonObject.optString("name");
ArrayList<String> artistClassArrayList3 = new ArrayList<String>();
artistClassArrayList3.add(name);
StringBuilder sbString = new StringBuilder("");
for(String language : artistClassArrayList3){
sbString.append(language).append(", ");
}
String strList = sbString.toString();
if( strList.length() > 0 )
strList = strList.substring(0, strList.length() - 1);
textView.setText(strList);
}
} catch (JSONException e) {
Toast.makeText(getApplicationContext(), "Error J :: " + e.getMessage(), Toast.LENGTH_SHORT).show();
}
}, error -> Toast.makeText(getApplicationContext(), "Error R:: " + error.getMessage(), Toast.LENGTH_SHORT).show());

I can not retrieve all key values from JSON object retrieved from HTTP request.
This is the returned JSON object from http request:
{"data":[{"movie_id":3,"movie_name":"Promithius","genre":"a dude","year":"2016","rating":45}]}
my Android Code:
try {
//HttpJsonParser httpJsonParser = new HttpJsonParser();
JSONObject JSonObj = (JSONObject) new
JSONTokener(result).nextValue();
String mymovie = JSonObj.getString("movie_name" );
String movieGenre = JSonObj.getString("genre" );
etResponse.setText("movie=" + mymovie + " genre=" +
movieGenre);
} catch (JSONException e) {
etResponse.setText("ERROR=" + e.getMessage());
e.printStackTrace();
}
When I run it in emulator with only:
String mymovie = JSonObj.getString("movie_name" );
etResponse.setText("movie=" + mymovie;
I get back the Movie name with no error. So the issue is I can retrieve movie_name but no Genre.
Error returned says "No value for genre"
Thanks in advance.

I think the data is JSONArray.
String result = "{\"data\":[{\"movie_id\":3,\"movie_name\":\"Promithius\",\"genre\":\"a dude\",\"year\":\"2016\",\"rating\":45}]}";
try {
JSONObject JSonObj = (JSONObject) new JSONTokener(result).nextValue();
JSONArray data = JSonObj.getJSONArray("data");
for (int i=0; i<data.length(); i++){
JSONObject jsonObject = data.getJSONObject(i);
String mymovie = jsonObject.getString("movie_name" );
String movieGenre = jsonObject.getString("genre" );
String dest = "movie=" + mymovie + " genre=" + movieGenre;
Log.d(TAG, dest);
}
} catch (JSONException e) {
e.printStackTrace();
}

Below is the code that finally worked for me. I hope it can help someone else.
try{
JSONObject object = new JSONObject(result);
JSONArray Jarray = object.getJSONArray("data");
object = Jarray.getJSONObject(0);
String MovieName = object.getString("movie_name");
String Genre = object.getString("genre");
String Rating = object.getString("rating");
String Year = object.getString("year");
etResponse.setText("Movie Name = " + MovieName + " \n Genre = " +
Genre + "\n Rating = " + Rating + " \n Year = " + Year );
} catch (JSONException e) {
etResponse.setText("JSONException: " + e.getMessage());
}

On click of selected date, I want to display related tasks or events.
public static List<ScheduledTasks> getResponse() {
String res = "[{\n" +
"\t\"scheduleId\": \"999\",\n" +
"\t\"eventType\": \"first\",\n" +
"\t\"impacts\": \"high\",\n" +
"\t\"startDate\": 27032018,\n" +
"\t\"endDate\": 27032018,\n" +
"\t\"machineOwner\": \"Nilesh\",\n" +
"\t\"description\": \"good\",\n" +
"\t\"status\": \"working\"\n" +
"}, ...
"}]";
return new Gson().fromJson(res, new TypeToken<List<ScheduledTasks>>(){}.getType());
this is the JSON.
Using the below
LayoutManager = new LinearLayoutManager(this);
String s = getIntent().getStringExtra("dateselected");
ScheduledTasks=getResponse();
adapter = new RecyclerAdapter(ScheduledTasks);
recyclerView.setAdapter(adapter);
List<ScheduledTasks>
I want to display only tasks for selected date.
String S date needs to be matched with json response and show particular tasks.
for date 27 only the tasks on that day should be displated.

try changing your getResponse method a bit like this so you can filter by date
public static List<ScheduledTasks> getResponse(String dateselected) {
String res = "[{\n" +
"\t\"scheduleId\": \"999\",\n" +
"\t\"eventType\": \"first\",\n" +
"\t\"impacts\": \"high\",\n" +
"\t\"startDate\": 27032018,\n" +
"\t\"endDate\": 27032018,\n" +
"\t\"machineOwner\": \"Nilesh\",\n" +
"\t\"description\": \"good\",\n" +
"\t\"status\": \"working\"\n" +
"}, ...
"}]";
JSONArray array= null;
JSONArray filter=new JSONArray();
try {
//change res to a JsonArray object so i can filter
array = new JSONArray(res);
try {
for (int i=0; i<array.length();i++){
String date=array.getJSONObject(i).has("startDate")?array.getJSONObject(i).getString("startDate"):"";
//if i match selected date i pick it
if (!TextUtils.isEmpty(date)&&date.equals(dateselected))
filter.put(array.getJSONObject(i));
}
}catch (JSONException e) {
e.printStackTrace();
}
} catch (JSONException e) {
e.printStackTrace();
}
//res
res=filter.toString();
return new Gson().fromJson(res, new TypeToken<List<ScheduledTasks>>() {

dose i retrieve data correctly ?

Is images json object string or json array? In your code is string.
If WebService changes are possible, request to given you a json array of images, this is best practice.
If not possible you must parse json image object with regex.

No your doing wrong just try below code
try {
JSONObject jsonObj = new JSONObject(jsonStr);
JSONArray arrayObj = jsonObj.getJSONArray("images");
for(int i=0;i<arrayObj.length();i++)
{
String item = arrayObj.getString(i);
// now you use item string where you want
}
} catch (JSONException e) {
e.printStackTrace();
}

images should be a JSONArray, and hence you can do that to parse it (inside your for loop!):
JSONArray imagesJSON = jsonObj.getJSONArray("images");
for(int k = 0 ; k<imagesJSON.length() ; k++){
String image = imagesJSON.getString(k);
item.setImage(IMAGE_LINK + image);//IMAGE_LINK +
Log.i(TAG, "parseResult: " + IMAGE_LINK + " " + image);
mGridData.add(item);
}

JSON is only displaying the last object '100 g' of "serving_description" in the JSON Formatted Data, See below. instead of all of the "serving_description" objects.
The Array is serving
If you look at the JSON Formatted Data below you will see that there are multiple "serving_description" 's.
I am trying to get the "serving_description" of all of the the available options to display instead of the last object in which it is displaying. How do I display all of the "serving_descriptions"?
I believe the error lies in, but I can be wrong, that is why I am asking :
for (int n = 0; n < foodName.length(); n++) {
JSONObject object = foodName.getJSONObject(n);
String shit = object.getString("serving_description");
Log.v("FATSEC", "" + shit);
ret = shit + "";
}
Class, AsyncTask
#Override
public void onClick(View v) {
new AsyncTask<String, String, String>() {
#Override
protected String doInBackground(String... arg0) {
search = (EditText) findViewById(R.id.editText1);
String SEARCH = search.getText().toString();
JSONObject food = getFood(SEARCH);
Log.v("FATSEC", "TEST");
String ret = "";
try {
JSONArray foodName = food.getJSONObject("food")
.getJSONObject("servings")
.getJSONArray("serving");
for (int n = 0; n < foodName.length(); n++) {
JSONObject object = foodName.getJSONObject(n);
String shit = object
.getString("serving_description");
Log.v("FATSEC", "" + shit);
ret = shit + "";
}
} catch (JSONException e) {
e.printStackTrace();
}
return ret;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
// ans.setText("# of Servings: " + result);
ans.setText("Servings: " + result);
}
}.execute();
}
});

Use + to append all serving_description value in ret as:
ret += shit + "\n\n";

Each iteration of the loop overrides the value of ret so that you are never able to accumulate them. For this reason, when you return it has the last value you stored there and none of the previous values that were wiped out. Consider using a StringBuilder.
StringBuilder builder = new StringBuilder();
...
for (int n = 0; n < foodName.length(); n++) {
JSONObject object = foodName.getJSONObject(n);
String shit = object.getString("serving_description");
Log.v("FATSEC", "" + shit);
builder.append(shit).append("\n");
}
...
return builder.toString();
