TextView in RecyclerView is not showed up

I've been trying to fix my code for a long time. I looked so so many places to find a solution but no avail. If you look at my code and show me why my TextViews in RecylerView is not showed, that'd be great.
I am trying to use WebSocket-ing and fetch data from internet. That should be displayed in the RecyclerView in a constantly updated way. Data ledgers from ripple servers are coming with a natural delay. I want to show their some aspects in RecyclerView. All TextViews can change in content, they are just to try it out.
Here is my WebSocketActivity code:

Anyone is able to come up with a solution why TextViews are not showed up?
From the LOG records I can get all the data From debugging, my lists are working correct as well.
Note: I used the StreamExceptionHandler class to differentiate between two stream outcomes. One is useful to me, other is not and that's why I do not do anything if I catch anything.
Plus, my custom classes are working correctly since my lists seems to be well working.
AFTER EDIT:
I changed the WebSocketActivity and adapter as such. No so much changed. But now, again strangely, I am gettin all the data. It is added to RecyclerView too, but it does not show itself until I try to scroll manually. Plus, whenever a new data is arrived, RecyclerView completely disappears, then if I scroll again, it gets back with the updated data. ANY SOLUTION after update?

Do you see this line in MyWebSocketAdapter:
holder.textView.setVisibility(View.INVISIBLE);

I guess, I found it. Since I changed the systematic and the code itself I cannot post the exact code to solve it but the key is overriding the runOnUiThread function within the button click. And you should change the RecyclerView binding and manager sets as well. Do it in a different place.
To override the runOnUiThread in an anonymous (inner) class, use this:
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
}
});
Hope this helps the future visitors.

How to restrict the duplicate entries in the Firebase Database

In my app my user is entering the category and that category is stored in the FirebseDB. After storing the value in the DB the user can view the inserted value in the Spinner.
At this point all works fine.
I want user to enter only unique value .so , if user wants to enter the value which is already there he should get a Toast.
Following is my activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.lenovo.baicactivitytest.MainActivity">
<Spinner
android:id="#+id/sp"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<Button
android:id="#+id/add_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="70dp"
android:text="Add" />
</RelativeLayout>
Following is my inputdialogue.xml:
<?xml version="1.0" encoding="utf-8"?>

}
}else
{
Toast.makeText(MainActivity.this, "Name Cannot Be Empty", Toast.LENGTH_SHORT).show();
}
}
});
d.show();
}
}

Can do this:
DatabaseReference ref=FirebaseDatabase.getInstance().getReference().child("Category");
ref.orderByChild("categoryname").equalTo(name).addValueEventListener(new ValueEventListener(){
#Override
public void onDataChange(DataSnapshot dataSnapshot){
if(dataSnapshot.exist()) {
Toast.makeText(MainActivity.this, "Name already exists", Toast.LENGTH_SHORT).show();
}
}
Can do the above, it will search in the Category node in the db, and if it exists then it will give you the Toast message.

whenever i run the app on emulator it says unfortunately the app has stopped working and the log reads as below

replace
com.exmaple.intel.dualboot.InSwipeRefreshLayout
with
android.support.v4.widget.SwipeRefreshLayout
in your xml file,
as the com.exmaple.intel.dualboot.InSwipeRefreshLayout class is not defined

com.exmaple.intel.dualboot.InSwipeRefreshLayout
Check this path if it is correct in your xml.It seems the path of "InSwipeRefreshLayout" is not corect

the com.exmaple.intel.dualboot.InSwipeRefreshLayout has that spelling of "exmaple", it should be example.

The posted layout working fine for me.Please check the package name properly com.example.intel.dualboot.InSwipeRefreshLayout whether exist or not and clean and build the project.

Step 1
- declare your activity inside of the manifest
Step 2
- starActivity(new Intent(getAcivity(), MyClass.class));
Step 3
- post your logcat if this didn't help while it should !
Edit: the issue seems that you are not setting a height to your layouts, base on your layout that you posted you have five layouts that are missing android:layout_height please add that and force close shall be gone.

Call multiple services in background in android

I have to call multiple services in background for a project in android app.
In each services i have to call separate web service and get some data and process it with local sqlite database. I am able to call each service separately and can manipulate its result with local database.
But not able to call all services in a sequence.
my code is as below:
#Override
public void onStart(Intent intent, int startid) {
Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
Timer timer = new Timer();
final SyncTableUsers syncUserObj = new SyncTableUsers(LocalService.this);
final SyncTableVehicles syncVehicleObj = new SyncTableVehicles(this);
final SyncTableLicenses syncLicenseObj = new SyncTableLicenses(this);
final SyncTableTags syncTagObj = new SyncTableTags(this);
final SyncTableTagMappings syncTagMapObj = new SyncTableTagMappings(this);
final SyncTableAddresses syncAddressObj = new SyncTableAddresses(this);
final SyncTableDispatches syncDispatchObj = new SyncTableDispatches(this);
final SyncEditCompany syncCompanyObj = new SyncEditCompany(LocalService.this);
final SyncEditVehicle syncEditVehicleObj = new SyncEditVehicle(LocalService.this);
final SyncEditUser syncEditUserObj = new SyncEditUser(this);
final SyncVehicleLog vLogObj = new SyncVehicleLog(LocalService.this);
TimerTask timerTask = new TimerTask() {
#Override
public void run() {
syncUserObj.syncUserData();
syncVehicleObj.syncVehicleData();
syncLicenseObj.syncLicensesData();
syncTagObj.syncTagData();
syncTagMapObj.syncTagMappingData();
syncAddressObj.syncAddressData();
syncDispatchObj.syncDispatchData();
syncCompanyObj.syncCompanyData();
syncEditVehicleObj.syncVehicleData();
syncEditUserObj.syncUserData();
Log.i("TAG", "LogId After insert values ");
}
}
};
timer.scheduleAtFixedRate(timerTask, 10000, 180000); call after every
3 minute
super.onStart(intent, startid);
syncUserData is a method, which call web service.

I recommend you go for the AsyncTask solution. It is an easy and straightforward way of running requests or any other background tasks and calling web services using devices having latest OS virsion you must need to use AsyncTask.
It's also easy to implement e.g. onProgressUpdate if you need to show a progress bar of some sort while running your requests.
private class YourTask extends AsyncTask<URL, Integer, Long> {
protected Long doInBackground(URL... urls) {
//call your methods from here
//publish yor progress here..
publishProgress((int) ((i / (float) count) * 100));
}
protected void onProgressUpdate(Integer... progress) {
setProgressPercent(progress[0]);
}
protected void onPostExecute(Long result) {
//action after execution success or not
}
}

Use Intent Service to execute your tasks in sequence.
