I am trying to get a part of JSON(that I have parsed previously) in a widget. I am using AsyncTask to separate it from main thread and I am using OkHttpClient library to get JSON. I have class PostTask that gets me the parsed JSON. But can please anyone tell me how can I display it in the widget. This is the code.
Create a custom event, something like this:
public class MyEvent {
private String text;
public MyEvent(String text) {
this.text = text;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text= text;
}
}
Now at the place where you're posting the Event, simply create this custom Event with the json you want to send to your widget. (put this code in onPostExecute).
EventBus.getDefault().post(new MyEvent(result);
Now simply wherever your textView is, in Activity or Fragment, register the eventBus in onCreate:
EventBus.getDefault().register(this);
And create a method that listens for the event like this:
#Subscribe
public void onMyEvent(MyEvent myEvent){
String text = myEvent.getText();
//Now you can parse this text, if it's JSON, or you can simply set it
//to your textView or whatever
}

I am getting json from Websockets and showing in recyler view. How do i update the list in real time when getting data from websockets?
My WebSocket Class
public final class EchoWebSocketListener extends WebSocketListener {
private static final int NORMAL_CLOSURE_STATUS = 1000;
private static final String TAG = "DashBoardScreen.this";
#Override
public void onOpen(WebSocket webSocket, Response response) {
super.onOpen(webSocket, response);
initially when connection is established i send some text to server
webSocket.send(builder.toString());
}
#Override
public void onMessage(WebSocket webSocket, String text) {
super.onMessage(webSocket, text);
in return server sends me data
output(text);
}
#Override
public void onMessage(WebSocket webSocket, ByteString bytes) {
super.onMessage(webSocket, bytes);
}
#Override

Log.d(TAG, "onClosing: ");
}
#Override
public void onClosed(WebSocket webSocket, int code, String reason) {
super.onClosed(webSocket, code, reason);
Log.d(TAG, "onClosed: ");

values.getString("service_Room_Number"),
values.getString("service_Name"),
values.getString("service_AssignedTo"),
values.getString("service_ID")
);
eventsDataModels.add(dataModel);
adapter = new EventListAdapter(eventsDataModels, context);
eventRecyclerView.setAdapter(adapter);
adapter.notifyDataSetChanged();
how exactly notifyDataSetChanged() works?
}
} else Toast.makeText(context, "No Events", Toast.LENGTH_SHORT).show();
System.out.println(builder.append(object.getString("status")));
} catch (JSONException e) {
e.printStackTrace();
}
}
});
}
Whenever your dataModel has the new data
eventsDataModels.add(dataModel);
adapter = new EventListAdapter(eventsDataModels, context);
eventRecyclerView.setAdapter(adapter);
If you perform the above operations and performing adapter.notifyDataSetChanged();
Will notify the adapter the new data has arrived and have to update the RecyclerView with new dataModel.

What is going wrong here? Please help.Thank you..
In your ServerResponse {"result":1}, the "result" is int, and you use String result = response.getString("result"), you should use getInt.
{"result":1,"message":"Success","cost":[{"pt_id":"5","ur_id":"2","pt_name":"mobile","pt_detail":"samsung
mobile ","pt_size":"0","pt_weight":"150","pt_start_loc":"nashik"}]}
Form your attached response, it seems that the value of result is an int value and you are trying to get this value using:
String result = response.getString("result"); // WRONG
Try using:
int result = response.getInt("result");

How to set CheckListItemsArrayList to the objects of checkListArrayList sequence wise? Please help. Thank you..
You need to elaborate your question. It is very confusing.
But I think that you want to add items to your AsyncTask class.
You can use the Constructor Method for this.
GetCheckListAsyncTask getCheckListAsyncTask = new GetCheckListAsyncTask(checkListsItemArray);
getCheckListAsyncTask.execute(mEventId);
And for AsyncTask Just Add:
JSONArray m_checkListsItemArray;
public GetCheckListsItemAsyncTask(JSONArray checkListsItemArray){
m_checkListsItemArray = checkListsItemArray;
//Do something here with checkListsItemArray;
}
And use m_checkListsItemArray anywhere in the AsycTask class.
Each time you start a task, you have no control when it ends. The tasks are running Asynchronously so they won't end in the order you start them. Maybe have a field level Array or ArrayList that adds results each time a task ends and then when everyhthing has ended you can work with the array results.
the code i am using is working very fine for me but the problem is i am not able to fetch that data in main activity
public class AsyncTaskParseJson extends AsyncTask<String, String, String> {
final String TAG = "AsyncTaskParseJson.java";
// set your json string url here
String yourJsonStringUrl = "http://demo.codeofaninja.com/tutorials/json-example-with-php/index.php";
// contacts JSONArray
JSONArray dataJsonArr = null;
#Override
protected void onPreExecute() {}
#Override
protected String doInBackground(String... arg0) {
try {
// instantiate our json parser
JsonParser jParser = new JsonParser();
// get json string from url
JSONObject json = jParser.getJSONFromUrl(yourJsonStringUrl);
// get the array of users
dataJsonArr = json.getJSONArray("Users");
// loop through all users
for (int i = 0; i < dataJsonArr.length(); i++) {
JSONObject c = dataJsonArr.getJSONObject(i);
// Storing each json item in variable
String firstname = c.getString("firstname");
String lastname = c.getString("lastname");
String username = c.getString("username");
// show the values in our logcat
Log.e(TAG, "firstname: " + firstname
+ ", lastname: " + lastname
+ ", username: " + username);
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(String strFromDoInBg) {}
}
this is the code new AsyncTaskParseJson().execute(); to make this thing work
but i need to run
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// we will using AsyncTask during parsing
new AsyncTaskParseJson().execute();
}`
I want to get the data like firstname , lastname , username as variable in main activity .
Is it possible ??
this is my other class IncomingCall.java when i want to get the variables
public class IncomingCall extends BroadcastReceiver {
private String firstname;
private String lastname;
private String username;
public void onReceive (Context context, Intent intent) {
// TODO Auto-generated method stub
Toast.makeText(context, " Calling "+username, Toast.LENGTH_LONG).show();
try {
if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
TelephonyManager.EXTRA_STATE_IDLE)
|| intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
TelephonyManager.EXTRA_STATE_OFFHOOK)) {
notifyuser=true;
}
} catch (Exception e) {
// TODO: handle exception
//Toast.makeText(context, "Error detected 1 "+e, Toast.LENGTH_LONG).show();
}
}
public class AsyncTaskParseJson extends AsyncTask<String, String, String> {
final String TAG = "AsyncTaskParseJson.java";
// set your json string url here
String yourJsonStringUrl = "http://demo.codeofaninja.com/tutorials/json-example-with-php/index.php";
// contacts JSONArray

#Override

// loop through all users
// for (int i = 0; i < dataJsonArr.length(); i++) {
JSONObject c = dataJsonArr.getJSONObject(0);
// Storing each json item in variable
firstname = c.getString("firstname");
lastname = c.getString("lastname");
username = c.getString("username");
// show the values in our logcat
Log.e(TAG, "firstname: " + firstname

// }
} catch (JSONException e) {
e.printStackTrace();
}
runOnUiThread(new Runnable() {
#Override
public void run() {
//Here you use your variables
}
});
return null;
}
protected void onPostExecute(String strFromDoInBg) {
Log.e("TAG1", "firstname: " + firstname
+ ", lastname: " + lastname
+ ", username: " + username);
}
}
this is my code
The method onPostExecute runs on the main thread, You need to use the data once the doInBackground finishes and control return to the main thread.
Better you use these data in the method
protected void onPostExecute(String strFromDoInBg) {
// use the firstname , lastname or username after this method call.
}
Put your code in your Main Activity class, and then use class variables to store what you want, e.g.:
public class MainActivity extends Activity {
private String[] firstname;
private String[] lastname;
private String[] username;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new AsyncTaskParseJson().execute();
}
public class AsyncTaskParseJson extends AsyncTask<String, String, String> {
final String TAG = "AsyncTaskParseJson.java";
// set your json string url here
String yourJsonStringUrl = "http://demo.codeofaninja.com/tutorials/json-example-with-php/index.php";
// contacts JSONArray
JSONArray dataJsonArr = null;
#Override
protected void onPreExecute() {}
#Override
protected String doInBackground(String... arg0) {
try {
// instantiate our json parser
JsonParser jParser = new JsonParser();
// get json string from url
JSONObject json = jParser.getJSONFromUrl(yourJsonStringUrl);
// get the array of users
dataJsonArr = json.getJSONArray("Users");
firstname = new String[dataJsonArr.length()];
lastname = new String[dataJsonArr.length()];
username = new String[dataJsonArr.length()];
// loop through all users
for (int i = 0; i < dataJsonArr.length(); i++) {
JSONObject c = dataJsonArr.getJSONObject(i);
// Storing each json item in variable
firstname[i] = c.getString("firstname");
lastname[i] = c.getString("lastname");
username[i] = c.getString("username");
// show the values in our logcat
Log.e(TAG, "firstname: " + firstname
+ ", lastname: " + lastname
+ ", username: " + username);
}
} catch (JSONException e) {
e.printStackTrace();
}
runOnUiThread(new Runnable() {
#Override
public void run() {
//Here you use your variables
}
});
return null;
}
#Override
protected void onPostExecute(String strFromDoInBg) {}

}
