How to Save the Values of recycler view in Sqlite Database

I have Recycler view where I am displaying the items with Item name, Item rate and quantity of the items which is increased and decreased by +/- buttons respectively. now, i want to get all the values from each item of the Recycler view and send it over the server or save it to local database so how to achieve this.?

}
}

So you are already passing the arraylist (teaItemList) in your constructor of your adapter. Since the reference is same you can use the same array list for saving or sending it to the database.
Since name and price of items are same, You need to get the value only like for if user clicks + = String.valueOf(count+ 1) and for (-) = String.valueOf(count - 1)
So add one more field like (int count) in teaPOJO and
whenever user clicks + :
Do this
holder.ivPlus.setOnClickListener (new View.OnClickListener () {
#Override
public void onClick(View view) {
int count=0;
TeaPojo teaPojo = teaItemList.get(getAdapterPosition);
try{
count = Integer.parseInt(holder.tvcount.getText().toString());
}
catch(Exception e) {
count = 0;
}
//count++;
count = Integer.parseInt(holder.tvcount.getText().toString());
holder.tvcount.setText(String.valueOf(count+ 1));
teaPojo.setCount(count);
Log.e ("count", String.valueOf (count));
}
});
User clicks - :
holder.ivMinus.setOnClickListener (new View.OnClickListener () {
#Override
public void onClick(View view) {
int count=0;
TeaPojo teaPojo = teaItemList.get(getAdapterPosition);
try{
count = Integer.parseInt(holder.tvcount.getText().toString());
}
catch(Exception e) {
count = 0;
}
if(count>0) {
//count--;
count = Integer.parseInt(holder.tvcount.getText().toString ());
holder.tvcount.setText (String.valueOf (count - 1));
teaPojo.setCount(count);
tealist.setCount (count);
}enter code here
}
});
// if you want to save in db from activity itself only
saveToDb(teaItemList);
// if you want to send to server from activity itself only
handleSendToServer(teaItemList);

CustomView in RecyclerView malfunctioning ( items get swapped , disappeared or repeated )

I am implementing a local chat_box like page, I have two Vectors queued_messages and messages. I remove items from queued list and add to the messages and wait in the asynctask to add other items.three kind of messages sent received and multiple choice questions.multiple choice questions have the problems in the title.(especially if you scroll to top page while they get loading)
1.I have already set has fixed size to true
2.tried making custom view directly in adapter instead of inflating a view containing it
3.set is recyclable to off and implemented both selected and unselected mode in onbindviewholder
4.tried different kind of notifies.
5.disabled scroll to last position

I wish that recyclerview works correctly(without any disappearing , repeated values or swaped items).

I am trying to display serial number to my AmountCartActivity of recycler view whichever I am selecting from previous HealthCartActivity using checkbox. And, I have implemented some code but I am not getting how to get the serial number.

Well, you can work-around. And you won't have to keep serialNumber variable in model just to track it's position.
You can use position parameter variable of onBindViewHolder() for serial number and counting.
i.e.
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
//here position is unique for every item in the list, so, you can use it as a serial number
// also, since it's starting from 0, you should add 1 with it, in case you wanna start from 1
// holder.textView2.setText(myDataList.get(position).getSerialNumber());
holder.textView2.setText("S.No. "+(position+1));
}

#Override
public void onBindViewHolder(ViewHolder holder, int position)
holder.id.setText(String.valueOf(" "+(position+1)));
Use above method.

You have to add serialNumber to your AmountCartModel.This will fix your problem

Put an id in your AmountCartModel as below;
public class AmountCartModel {
private int serialNumber; // add this line
private String testName;
private String testPrice;
private Integer totalPrice;
public AmountCartModel() {
this.serialNumber= serialNumber; // add this line
this.testName = testName;
this.testPrice = testPrice;
this.totalPrice = totalPrice;
}
public int getSerialNumber (){
} // add this line
public void setSerialNumber(int serialNumber) {
}// add this line also
Then retrieve this serialNumber from each view.
Since you are sending the intent form onBackPressed(); attach the list as an extra to the intent as follows,
#Override
public void onBackPressed() {
super.onBackPressed();
startActivity(new
Intent(AmountCartActivity.this,HealthServicesActivity.class).putParcelableArrayList("the list", mDataList));
finish();
}
Please ensure the object (AmountCarModel) you are making a list from extends Parcelable, and catch it in the HealthServiceActivity in onResume()
Alternatively, and probably the best way, is to attach the serialNumber inside the HealthServiceActivity in the Retrofit onResponse() method as below;
#Override
public void onResponse(Call<JSONResponse> call, Response<JSONResponse> response) {
JSONResponse jsonResponse = response.body();
data = new ArrayList<>(Arrays.asList(jsonResponse.getResult()));
if (data != null){
for (int i = 0; i<data.size(); i++) {
data.setSerialNumber(i);}}
madapter = new RecyclerAdapter(data);
recyclerView.setAdapter(madapter);
}

In AmountCartModel serialNumber is of String datatype
and while putting object you are setting
counting = extras.getInt("serialNumber");
//Just add your data in list
AmountCartModel mydata = new AmountCartModel(); // object of Model Class
mydata.setTestName(testName );
mydata.setTestPrice(testPrice);
mydata.setTotalPrice(Integer.valueOf(totalPrice));
mydata.setSerialNumber(counting);
and you are storing it in ArrayList without for loop so every time only one object will get inclued in your arraylist

try this way
int count = 0;
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.submit_button:
int totalAmount = 0;
int totalPrice = 0;
String testName = "";
String testPrice="";
List<TestListModel> stList = ((RecyclerAdapter) madapter)
.getTestList();
for (int i = 0; i < stList.size(); i++) {
TestListModel singleStudent = stList.get(i);
//AmountCartModel serialNumber = stList.get(i);
if (singleStudent.isSelected() == true) {
testName = testName + "\n" + singleStudent.getTest_name().toString();
testPrice = testPrice+"\n" + singleStudent.getTest_price().toString();
count++;
totalAmount = Integer.parseInt(stList.get(i).getTest_price());
totalPrice = totalPrice + totalAmount;
}
}
Toast.makeText(HealthServicesActivity.this,
"Selected Lists: \n" + testName+ "" + testPrice, Toast.LENGTH_LONG)
.show();
Intent in= new Intent(HealthServicesActivity.this, AmountCartActivity.class);
in.putExtra("test_name", testName);
in.putExtra("test_price", testPrice);
in.putExtra("total_price", totalPrice);
in.putExtra("serialNumber", count);
startActivity(in);
finish();
break;
/** back Button Click
* */
case R.id.back_to_add_patient:
startActivity(new Intent(getApplicationContext(), PatientActivity.class));
finish();
break;
default:
break;
}
}

I found the answer. I have done code for serial number like below. Here I am getting serial number in front of the elements. In this code I took one int variable and initialized with value 1. After that I call srNo variable in for loop then incremented at the end of the for loop.
int srNo = 1;
List < TestListModel > stList = ((RecyclerAdapter) madapter)
.getTestList();
for (int i = 0; i < stList.size(); i++) {
TestListModel singleStudent = stList.get(i);
if (singleStudent.isSelected() == true) {
testListId = testListId + "\n" + Integer.parseInt(String.valueOf(srNo));
testName = testName + "\n" + singleStudent.getTest_name().toString();
testPrice = testPrice + "\n" + singleStudent.getTest_price().toString();
srNo++;
totalAmount = Integer.parseInt(stList.get(i).getTest_price());
totalPrice = totalPrice + totalAmount;
}
}

I'm not sure which of these classes I need to be restoring and how I can restore the previous details and images in HomeFragment after clicking back from the detail activity. I would be able to just describe a parent activity in my manifest but the main class holding everything is a fragment and android doesn't let you choose parent fragments! Any ideas or help would be appreciated.

Try to remove initialization of List from declaration.
private List buyersProfiles = new ArrayList();
And make initialization in onCreateView method if List is null.

You can set listener to null to disable the onclick event
ucover.setOnClickListener(null)
If you want to resume the click event simply call
ucover.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(getApplicationContext(), Fullimage.class);
i.putExtra("images", USER_IMG);
startActivity(i);
}
});
Hops this help.

you can check the lenght of your arraylist and then according the that set a message to user
if(picarray.length()!=0)
{
ucover.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(getApplicationContext(), Fullimage.class);
i.putExtra("images", USER_IMG);
startActivity(i);
}
});
}
else
{//show your message here
}

Check your array length and if it is non zero enable the onclick listner..
if(picarray.length != 0)
{
ucover.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(getApplicationContext(), Fullimage.class);
i.putExtra("images", USER_IMG);
startActivity(i);
}
});
}
