Try like this :
progressDialog = new ProgressDialog(getActivity());
And if you wish to customize your dialog and put self created Layout in it.
/**
* Created by vivek on 18/10/16.
*/
public class CustomDialog {
private static Dialog dialog;
private static Context context;
public CustomDialog(Context context) {
this.context = context;
}
/**
* Comman progress dialog ... initiates with this
*
* #param message
* #param title
*/
public static void showProgressDialog(Context context, String title, String message) {
if (dialog == null)
{
dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.custom_loader);
dialog.setCancelable(false);
dialog.setCanceledOnTouchOutside(false);
dialog.show();
}
}
public static boolean isProgressDialogRunning() {
if (dialog != null && dialog.isShowing()) {
return true;
} else return false;
}
/**
* Dismiss comman progress dialog
*/
public static void dismissProgressDialog() {
if (dialog != null && dialog.isShowing()) {
dialog.dismiss();
dialog = null;
}
}
} // End of main class over here ...

Replace this:-
progressDialog = new ProgressDialog(getContext(), ProgressDialog.THEME_HOLO_LIGHT);
with
progressDialog = new ProgressDialog(getActivity());

May be. you are showing two progressdialog and both of that progressbar on screen.. but when you dismiss your progressbar at that time the previous one is override by other one before you dismiss first one .. so the firstone is always in screen. that's the issue.

I tried everything.But none of the answers solved the issue.However,i solved it by overriding onResume() method in the fragment.
Thanks All.

How can I control the Recycle View by clicking on the date of the calendar view?

I'm new in android and also new in English sorry my bad English...
I have learned android course at the academy.
My sentence may be wrong because it is written through a translator. I hope you understand with a generous heart.
Here's what I want:
If I click 15 days in Calendar View,
It is hoped that only the 15th day information will be shown in the Recyclerview. If I click on another date in calenderview, for example, 20 days, I hope that the 15th item will disappear and only the 20th item view will be displayed.
Here's what I'm trying to do.
When I click a date in a calendar view, I want to see the Item View corresponding to that date.

First you need to add new entry in your existing mArrayList as i am can see from your code you are adding all existing entries again but not new entry.
After that you need to set adapter again with new mArrayList only then you will be able to see new data in your recycler view.

while retreiving contacts again on onResume, last contact is re-added on first card in recycler view

I do not understand why last contact is added to the first card in recyclerview again when activity is resumed. I know that it is to do with cursor or content resolver.
Here is the java class with which I have problem.

Here is what I found which is adding one more item in your list
Try removing:
if (contactsObject != null) {
contactsArrayList.add(contactsObject);
Log.e("object added : ", contactsObject.getName);
}
Hope this helps.

Adapter, Timer and concurrency in Android

Main goal: android app-messendger for chating with company support.
Task: To impliment timers of waiting response from operator or client in listview.
Trouble: In all listview items rendering one of all timer, and then application is listing some timers for a moment are rendering for correctly result, but when they are overlap.

android : Badge not remove from calendar

I am creating calendar which contains events and I want to show total no of events on particular date. I am using
CalendarAdapter.java class. For showing total no. of events count (like notification bubble) on date I am using
Badge.java class. Now problem is that badge is apply on Calendars dates which current month is showing first,
after changing month then that badge is not remove from next month calendar.

How do I use onResume and onPause method when I am pressed back button

I have a custom adapter for recyclerview using json webservices. I had to parse the url one by one and show cardview using onscrolllistener(). My question is when I pressed the back button and after I open in recent app (that time onResume called) it will show only which url called at the time of onPause called. So how can I refresh the listview when I call onResume.
Thanks in Advance,

I made a small mistake declaring String URL as static but it should be final also assign to another String variable. Finally set the adapter and notifyDataSetChanged where placed in onStart().

private String mNextToken;
JSONObject jsonObj;
private boolean loading = true;
int visibleItemCount, totalItemCount, pastVisiblesItems;
private List<PlayListItem> mContactList;
private PlayListItem mContact;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

mProgressBar = (ProgressBar) findViewById(R.id.progressBar);
mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
mRecyclerView.setHasFixedSize(true);

if (mContactList == null)
mContactList = new ArrayList<PlayListItem>();
System.out.println("onCreate :: Size2---->" + mContactList.size());

#Override

super.onStart();

mContactList.clear();
url = URL;
new GetContacts().execute();
if (mAdapter == null)
mAdapter = new CardAdapter(MainActivity.this, mContactList);
mRecyclerView.setAdapter(mAdapter);
mAdapter.notifyDataSetChanged();
getScreenOrientation();

ProgressDialog.show() is not showing the progress dialog - android

Replace this:- progressDialog = new ProgressDialog(getContext(), ProgressDialog.THEME_HOLO_LIGHT); with progressDialog = new ProgressDialog(getActivity());

May be. you are showing two progressdialog and both of that progressbar on screen.. but when you dismiss your progressbar at that time the previous one is override by other one before you dismiss first one .. so the firstone is always in screen. that's the issue.

I tried everything.But none of the answers solved the issue.However,i solved it by overriding onResume() method in the fragment. Thanks All.
