*************PROBLEM FIXED, CHECK BELOW FOR A SOLUTION*************
I have been struggling with that nearly half a day. Cannot get it work properly.
I have AsyncTask with private method, so I can pass boolean and String values in CustomLvAdapter
private void changeJobStatus(final boolean isAppliedforAJob, final String jobID){
class ChangeJobStatus extends AsyncTask<Void,Void,String> {
//private Delegates del = null;
ProgressDialog loading;
#Override
protected void onPreExecute() {
super.onPreExecute();
if(isAppliedforAJob) {
loading = ProgressDialog.show(context, "","Canceling application", false);
}
else {
loading = ProgressDialog.show(context, "","Applying for position", false);
}
}
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
//del.asyncCompleteOnCustomJob(true);
loading.dismiss();
}
#Override
protected String doInBackground(Void... v) {
String res;
HashMap<String,String> params = new HashMap<>();
params.put(Config.KEY_USER_ID, studentID);
params.put(Config.KEY_JOB_ID, jobID);
RequestHandler rh = new RequestHandler();
if(isAppliedforAJob)
res = rh.sendPostRequest(Config.URL_CANCEL_APPLICATION, params);
else
res = rh.sendPostRequest(Config.URL_APPLY_FOR_A_JOB, params);
Log.d("Stringas", "CustomListViewBackground " + res);
return res;
}
}
ChangeJobStatus cjs = new ChangeJobStatus();
cjs.execute();
}
and in onPostExcecute() I want to call notifyOnDataSetChanged() to my another activity lvAdapters.
As far as I read I have to implement delegate interface, but I didnt succeed doing that. I fail at initializing delegate in my main class, because changeJobStatus method is private and it is called in customLvAdapter class.
If I make a constructor in ChangeJobStatus class
public ChangeJobStatus(Delegates delegate)
{
this.del = delegate;
}
I have to pass something in the parameters, when excecuting it. If I pass new Delegate, my delegate implementation, which is in my another activity is not triggered.
ChangeJobStatus cjs = new ChangeJobStatus(new Delegates() {
#Override
public void asyncCompleteOnCustomJob(boolean success) {
//whatever
}
});
cjs.execute();
I hope you can help me figure out right implementation for that,
Cheers
***********SOLUTION***********
Sadly, I couldn't implement what fellow user gave to me, but I am very glad that I heard from one of you I can use broadcast receiver. And it worked.
This is what I did
Create a Broadcast Receiver in your main class
private final BroadcastReceiver broadcastJobList = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
//what will happen, when event triggers
}
};
Register custom intent and register it to Broadcast receiver in your main class onCreate method or wherever you feel comfortable :)
IntentFilter filter = new IntentFilter();
filter.addAction("jobListChanged");
registerReceiver(broadcastJobList, filter);
All we left to do is send intent which will trigger Broadcast receiver. Following code in my scenario went to onPostExcecute method in custom adapter (context was initialized for Context at the beggining of custom adapter)
Intent intent = new Intent();
intent.setAction("jobListChanged");
context.sendBroadcast(intent);
Hope I will help anyone that has this problem. Cheers!
// your asynctask class
public class ChangeJobStatus extends AsyncTask<String, Void, String> {
private ProgressDialog loading;
private OnResponseListener responseListener;
private boolean isAppliedforAJob;
private Context con;
public ChangeJobStatus(Context con,boolean state) {
super();
// TODO Auto-generated constructor stub
this.con=con;

I know this is a duplicate question but please hold on. I have read some similar questions and answer but none of them seems working for me.
What to do:
I have to do a search which will send a request to a web service and receive a response.
As i can't consume network on UI thread, I used AsyncTask.
What i tried:
I tried using task.execute() this returns immediately without even showing progressdialog box and i receive response as null (set in onPostExecute)
if i use task.execute.get() then it freezes screen and again no dialog box shows up (but i receive response correctly).
Below is my code with task.execute. Kindly correct me.
public class LookIn extends AppCompatActivity implements View.OnClickListener{
private Button btn=null;
private TextView txtPinCode=null;
private Service service=null;
private final static int timeout=20;
private String jsonResponse;
//private ProgressBar helperSearchProgressBar;
private String pincode="";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_look_in);
btn=(Button)findViewById(R.id.button);
btn.setOnClickListener(this);
txtPinCode=(TextView) findViewById(R.id.txtPinCode);
this.service=(Service) ParamFactory.getParam(ConstantLabels.SELECTED_SERVICE_ID);
// this.helperSearchProgressBar=(ProgressBar)findViewById(R.id.helperSearchProgressBar);
}
#Override
public void onClick(View v) {
String pincode= txtPinCode.getText().toString();
if(pincode==null || pincode.isEmpty() || pincode.length()!=6)
{
this.txtPinCode.setError("Please enter a 6 degit pin code from 700000 to 700200");
return;
}
ParamFactory.setParam(ConstantLabels.PINCODE_ID,pincode);
this.pincode=pincode;
loadHelper();
Intent intent= new Intent(LookIn.this,SearchResult.class);
startActivity(intent);
}

ParamFactory.setParam("getHelperForService", adapter);
}
catch(JSONException x)
{
Log.e("Callme", Log.getStackTraceString(x));
}
}
class CallmeGetHelperAsyncTask extends AsyncTask<String,Void,String > {
// private Context context=null;
private ProgressDialog dialog=null;
private String jsonResponse;

public CallmeGetHelperAsyncTask(){}
public CallmeGetHelperAsyncTask(LookIn activity)
{
this.activity=activity;
}
#Override
protected void onPreExecute() {

this.dialog.setMessage("Loading...");
this.dialog.show();
Log.v("Callme","Dialog Shown");
}
#Override

if(s!=null)
{
this.activity.setJsonResponse(s);
}
else
{
Log.v("Callme","kill me");
}
if(this.dialog.isShowing())
{
Log.v("Callme","Closing Dialog");
this.dialog.dismiss();
}
}
#Override
protected String doInBackground(String... params) {
Log.v("Callme","From Background:"+Thread.currentThread().getId());
String pincode=params.clone()[0].split(",")[0];
String serviceId=params.clone()[0].split(",")[1];
String url=String.format(URL.GET_HELPER,serviceId,pincode);
jsonResponse= null;
try {
jsonResponse = RestUtil.makeRestRequest(url);
} catch (IOException e) {
e.printStackTrace();
}
return jsonResponse;
}
}
}
Note: I haven't tried using while loop to waiting for the asynctask, because i think that will also end up freezing my screen. Please correct me if i am wrong
I haven't tried using while loop to waiting for the asynctask
No need to use loop for waiting AsyncTask Result.
Because onPostExecute method execute after doInBackground so instead of using jsonResponse just after call of execute method, do it inside setJsonResponse method, because this method called from onPostExecute which always run on Main UI Thread:
public void setJsonResponse(String jsonResponse)
{
this.jsonResponse=jsonResponse;
//Create adapter object here
result= RestUtil.getUserList(jsonResponse);
adapter = new ArrayAdapter(...);
ParamFactory.setParam("getHelperForService", adapter);
}
This question already has answers here:
how to return result from asyn call
(2 answers)
Closed 7 years ago.
Activity.java
//Activity stuff
MyClass mc = new MyClass();
mc.getText();
public void dosomething() {
textview.setText(mc.getText());
}
MyClass.java
class MyClass {
String text;
public void setText() {
class GetTextFromWEB extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... urls) {
String url = urls[0];
String output;
//Getting text from web
return output;
}
#Override
protected void onPostExecute(String _text) {
text = _text;
}
}
String url = "google.com";
//Doing with url something
new GetText().execute(url);
}
public String getText() {return text;}
}
Promblem is - in activity setText do faster, then AsyncTask do it's job.
So when setText run, it's run like setText(null)
I need to check in activity, is asynk ended, so i have my text to set.
I hope i explained it
And i don't even need exactly AsyncTask, i need jsoup working, so if there is solution with another thread-class, with which jsoup will work, i can use it
Edit
class GetLyrics extends AsyncTask<String, Void, String> { //Class for getting lyrics
private Context con;
public GetLyrics(Context con) {
this.con = con;
}
#Override
protected String doInBackground(String... urls) {
//do something
}
#Override
protected void onPostExecute(String _lyrics) {
lyrics = _lyrics;
con.runOnUiThread(new Runnable() {
#Override
public void run() {
((TextView) findViewById(R.id.lyricsOutput)).setText(lyrics);
}
});
}
}
Call the method setting your text in the postExecute inside your AsyncTask or set the text directly on your postExecute method.
And wrap the line with setText() inside runOnUIThread (otherwise you will get an exception saying that the view can be accessed only by the thread that created it, since you are setting the text from async task).
Setting the text would be something like this
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
((TextView) findViewById(R.id.txtFieldName)).setText("your text");
}
});
That way you can quit worrying about checking if the async task is finished. But avoid doing complex ui operations like this. Since this is just setting the text on TextView, it should be allright.

Example
I have an AsyncTask class SearchForQuestions that is called from an Activity QuizMap. When looping through an array in SearchForQuestions I can't find the correct context for toast to appear within the AsynTask.
The standard Toast.makeText(getApplicationContext(), "This is Toast!!!", Toast.LENGTH_SHORT).show(); gives error getApplicationContext() undefined.
I have tried some of the solutions to this offerred by SO, most of them are listed here and concern getting UiThread and running on that.
I can't get this to work however. Here's example code snippets of what i have tried. I have put a method in QuizMap and try calling it from SearchForQuestions but SearchForQuestions isn't recognised. How can I get around this? )Still a newbie at java...)
// QuizMap activity
public class QuizMap extends FragmentActivity
implements OnMarkerClickListener {
private GoogleMap map;
private static final String TAG = "QuizMap"; // debugging
...
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_quizmap);
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
...
}
// make toast inside AsyncTask
public void showNotNearToast(final String toast) {
QuizMap.this.runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(QuizMap.this, "This is Toast!!!", Toast.LENGTH_SHORT).show();
}});
}
.
// SearchForQuestions class
private class SearchForQuestions extends AsyncTask<String, Void, DataHandler> {
// checks for proximity to question locations
Location location =
locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
#Override
protected DataHandler doInBackground(String... pointsList) {
String result = pointsList[0];
...
}
#Override
protected void onPostExecute(DataHandler result) {
ArrayList<String> resultsArray = result.results;
Integer numPoints = resultsArray.size();
for (int i =0;i<numPoints;i++){
String[] pointDetails = resultsArray.get(i).split("::");
...
// we can make use of the Android distanceTo function to calculate the distances
float distance = location.distanceTo(fixedLoc);
if (i > DIST) { // this is UCL
showNotNearToast("My Message"); // showNotNearToast undefined
if (distance < DIST) {
...
}
};
I'm going t close this question. I haven't solved my problem but the number of answers provided that apparently work in other situations suggest there's something else going on. I'm going to re-structure the classes to get around having to call from within AsyncTask.
Just Toast it, why do you want to create a function for it? onPostExecute() is already on UI thread.
You are not able to access because inner Class can not call functions of Outer class unless you pass instance of the outer class.
Call your toast in onPostExecute
Create an interface for a callback.
public interface ToastCallback {
public void invoke(String text);
}
Your AsyncTask constructor
private ToastCallback toastCallback;
public SearchQuestions(ToastCallback callback) {
this.toastCallback = callback;
}
// in doInBackground() {
toastCallback.invoke("Toast from background");
}
In Your Activity,
private void showNotNearToast(String text) {
runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(), text, Toast.LENGTH_SHORT).show();
}
});
}
public class MyToastCallback implements ToastCallback {
#Override
public void invoke(String text) {
showNotNearToast(text);
}
}
// Asynctask call
new SearchQuestion(new MyTosatCallback()).execute(<Your params here>);
Try this from inside your AsyncTask:
myActivity.this.runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(activity, "Hello", Toast.LENGTH_SHORT).show();
}
});
Where you have your
showNotNearToast("My Message"); // showNotNearToast undefined
Replace myActivity with the name of your Activity.
(Ab)use the publishProgress method
private class ToastAsyncTask extends AsyncTask<Void, String, Void>{
#Override
protected Void doInBackground(Void... voids) {
SystemClock.sleep(1000);
publishProgress("Toast msg string");
SystemClock.sleep(1000);
return null;
}
#Override
protected void onProgressUpdate(String... values) {
Toast.makeText(getApplicationContext(), values[0], Toast.LENGTH_SHORT).show();
}
}
**UPDATE: ** since you are having problems with context for some reason, use this version. Tough the implementation above works for me.
private class ToastAsyncTask extends AsyncTask<Void, String, Void> {
private WeakReference<Context> contextRef;
public ToastAsyncTask(Context context) {
contextRef = new WeakReference<Context>(context);
}
#Override
protected Void doInBackground(Void... voids) {
SystemClock.sleep(1000);
publishProgress("Toast msg string");
SystemClock.sleep(1000);
return null;
}
#Override
protected void onProgressUpdate(String... values) {
if (contextRef.get() != null) {
Toast.makeText(contextRef.get(), values[0], Toast.LENGTH_SHORT).show();
} else {
// The context was destroyed.. check what you are doing
}
}
}
Use it like this
new ToastAsyncTask(MainActivity.this).execute();
Pass the activity into the AsyncTask. See below.
private class SearchForQuestions extends AsyncTask<String, Void, DataHandler> {
Activity activity;
public void SearchForQuestions(Activity activity){
this.activity = activity;
}
//... rest of the code
public class QuizMap extends FragmentActivity implements OnMarkerClickListener {
/*...*/
new SearchForQuestions(this).execute();
/*...*/
/*When calling the toast:*/
Toast.makeText(this.activity, "This is Toast!!!", Toast.LENGTH_SHORT).show();
i use a class WebServiceAdapter using volley library for implementing http connections. since i can't find a way to return a string to activity
i use an interface to callnback into MainActivity. in it i want to start a new activity but it is not starting
my WebServiceAdapterClass
public WebServiceAdapter(Context context){
this.context = context;
status = "new";
rQueue = Volley.newRequestQueue(context);
}
private WebServiceInterface wsi;
public void sendGetRequest(String page,Map<String,String> map, WebServiceInterface i){
wsi = i;
String query = "";
if(!map.isEmpty()){
for (Map.Entry<String, String> entry : map.entrySet())
{
query =query + entry.getKey()+"="+entry.getValue()+'&';
}
}
if(query.length() != 0)
query = query.substring(0,query.length()-1);
StringRequest sRequest = new StringRequest(Request.Method.GET,BASE_URI+page+"?"+query,
new Response.Listener<String>() {
#Override
public void onResponse(String response){
wsi.successCallback(response,context);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error){
wsi.errorCallback("failed",context);
}
});
rQueue.add(sRequest);
}
and in MainActivity inside callBack which use an interface for callback
#Override
public void successCallback(String s, Context c) {
Intent myintent = new Intent(c,VerifyRegister.class);
startActivity(myintent);
finish();
}
but the activity is not starting
i tried passing this , getApplicationContext() and Main Activity.this instead of c. but never worked
what i wanted was return a string on success i cant find another way
but the new activity is not starting
update
code of verifyRegister class
public class VerifyRegister extends Activity implements WebServiceInterface{
private Button verifyButton;
private EditText loginVerify;
StorageAdapter sAdapter;
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
sAdapter = new StorageAdapter();
if(sAdapter.getValue(this, "phone").length() == 0)
finish();
setContentView(R.layout.login_verify);
verifyButton = (Button) findViewById(R.id.verifyButton);
loginVerify = (EditText) findViewById(R.id.loginVerify);
verifyButton.setOnClickListener(new OnClickListener(){
public void onClick(View v){
}
});
}
#Override
public void successCallback(String s, Context c) {
// TODO Auto-generated method stub
}
#Override
public void errorCallback(String s, Context c) {
// TODO Auto-generated method stub
}
*update 2 *
i called the WebService Adapter like this
wAdaptor = new WebServiceAdapter(this);
wAdaptor.sendGetRequest("/register",new HashMap<String,String> (),this);
Please verify that your VerifyRegister class does in fact extends Activity. And if it does extends, please make sure that you have added it in AndroidManifest file.
One more thing you can try is, you can write it like this:
Intent myintent = new Intent(MainActivity.this,VerifyRegister.class);
Try this:
#Override
public void successCallback(String s, Context c) {
Intent myintent = new Intent(MainActivity.this,VerifyRegister.class);
c.startActivity(myintent);
//finish(); Dont use this
}
New activity starts with Context, I your case you should call it by using to activity currently running.
MainActivity.this.startActivity(anyintent);
i searched similar projects in github
and found this
public void successCallback(String s, Context c) {
Intent myintent = new Intent(MainActivity.this,VerifyRegister.class);
MainActivity.this.startActivity(myintent);
finish()
}
In my android app, i am doing time consuming task extending AsyncTask, and want to display the progress in Toast messages. Toast messages are also displayed onPre() and onPost().
I am able to display Toast messages onPre() & onPost() but not able to show onProgressUpdate(Integer... progress).
Following is my code...
public class MainClass extends Activity {
public void Start(View view) {
DemoTasks runner = new DemoTasks(this);
runner.execute("Start");
}
private class DemoTasks extends AsyncTask<String, Integer, Integer> {
private Context context;
public DemoTasks(Context context){
this.context = context;
}
#Override
protected Integer doInBackground(String... params) {
try {
publishProgress(0);
doWork();
Thread.sleep(5000L);
publishProgress(100);
} catch (Exception localException) {
Log.d("POST", localException.getMessage());
}
return 100;
}
#Override
protected void onPostExecute(Integer result) {
Toast.makeText(context, "post", Toast.LENGTH_SHORT).show();
}
#Override
protected void onPreExecute() {
Toast.makeText(context, "pre", Toast.LENGTH_SHORT).show();
}
#Override
protected void onProgressUpdate(Integer... progress) {
super.onProgressUpdate(progress);
Toast.makeText(context, "progress-" + progress, Toast.LENGTH_SHORT).show();
}
}
}
Also in my doInBackgroud(String...params) ...Thread.sleep is also not working.
As soon as onPre() gets executed, onPost() also executes after that!!!!
You can try this,
showProgress ();
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
dialog.cancel();
Intent i=new Intent(getApplicationContext(),Main.class);
startActivity(i);
finish();
}
}, 3000); //number of seconds
private ProgressDialog dialog;
public void showProgress () {
dialog = new ProgressDialog(this);
dialog.setCancelable(true);
dialog.setMessage("Please wait");
dialog.show();}
Bascially,you can access the UI on any method, even In doinBackground you can access the UI using runOnUIthread.
here is one AsyncTask Example. This will show a peogress dialog while executing the task.
private class LoginProcessing extends AsyncTask<Object, Void, Void> {
private LoginCredentials myLoginCredentials;
private ProgressDialog progressDialog;
public LoginProcessing(LoginCredentials Credentials) {
super();
myLoginCredentials=Credentials;
progressDialog.setMax(100);
progressDialog.setMessage("Please Wait..");
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressDialog.setProgress(0);
progressDialog.show();
}
protected void onPreExecute (){
}
#Override
protected Void doInBackground(Object... arg0) {
// TODO Auto-generated method stub
//Code to do the process in background
return null;
}
#Override
protected void onProgressUpdate(Long... progress) {
// int percent = (int)(100.0*(double)progress[0]/mFileLen + 0.5);
progressDialog.setProgress(progress);
}
protected void onPostExecute(Void result){
progressDialog.dismiss();
//Your code after the process
}
}
You can call this Task as,
new LoginProcessing(loginCredentials).execute();
In this Example loginCredentials is the parameter I am passing to the AsyncTask. You can change it to your own parameter.
