I am using jd-alexander/LikeButton https://github.com/jd-alexander/LikeButton instead of normal buttons in the android app. The code works fine while enabling and disabling switches. But I want to save the state of the like button. Suppose I enable the like button and swap the list the background code will run fine but the like button state will change to unliked.
Every time when I swap the list the like button state becomes unliked. Is there any way to save the like button State??

This is the normal behaviour in ArrayAdapter, the whole list gets recreated again so you lose the state of the button. You should save the boolean of the button in the local list variable.
Add a field like isLiked = true/false in the Collector class and update the value at the particular position every time user click like/unlike buttons.
I have Class Orders:
public class Order extends RealmObject {
#PrimaryKey
#SerializedName("Id")
private int id;
#SerializedName("Contractor")
private Contractor contractor;
#SerializedName("ItemAmounts")
private RealmList<ItemAmount> itemsAmounts = new RealmList<>();
#SerializedName("ModificationDate")
private Date modificationDate;
#SerializedName("ExportDate")
private Date exportDate;
#SerializedName("Export")
private boolean exportStatus;
#SerializedName("User")
private User user;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public Contractor getContractor() {
return contractor;
}
public void setContractor(Contractor contractor) {
this.contractor = contractor;
}
public RealmList<ItemAmount> getItemsAmounts() {
return itemsAmounts;
}
public void setItemsAmounts(RealmList<ItemAmount> itemsAmounts) {
this.itemsAmounts = itemsAmounts;
}
public Date getModificationDate() {
return modificationDate;
}
public void setModificationDate(Date modificationDate) {
this.modificationDate = modificationDate;
}
public Date getExportDate() {
return exportDate;
}
public void setExportDate(Date exportDate) {
this.exportDate = exportDate;
}
public boolean isExportStatus() {
return exportStatus;
}
public void setExportStatus(boolean exportStatus) {
this.exportStatus = exportStatus;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
And i Create any new order save to Realm:
public void insertOrUpdate(Order order) {
Order orderToCompare = realm.where(Order.class)
.equalTo("id", order.getId()).findFirst();
realm.beginTransaction();
if (orderToCompare == null) {
Order orderRealm = realm.createObject(Order.class, order.getId());
orderRealm.setExportStatus(order.isExportStatus());
orderRealm.setContractor(order.getContractor());
orderRealm.setModificationDate(order.getModificationDate());
} else if (!orderToCompare.equals(order)) {
realm.copyToRealmOrUpdate(order);
}
realm.commitTransaction();
}
All my Orders have List of ItemAmount and ItemAmount have single item(Items is also contains in Realm) and his amount. So when i try change the amount of item in one order all my amount in others ItemAmount is updated. Below its function which I update the amount:
recyclerView.addOnItemTouchListener(new RecyclerTouchListener(getApplicationContext(), recyclerView, new RecyclerTouchListener.ClickListener() {
#Override
public void onClick(View view, int position) {
itemPosition = position;
AlertDialog.Builder builder = new AlertDialog.Builder(OrderItemsActivity.this);
View mView = getLayoutInflater().inflate(R.layout.change_amount, null);
builder.setView(mView);
final AlertDialog alertDialog = builder.create();
alertDialog.show();
Button changeAmountButton = (Button) mView.findViewById(R.id.changeAmountButton);
final EditText setAmountEditText = (EditText) mView.findViewById(R.id.setAmountEditText);
changeAmountButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (setAmountEditText.getText().toString().isEmpty()) {
Toast.makeText(getApplicationContext(), "Pole nie może być puste", Toast.LENGTH_SHORT).show();
} else {
orderDAO = new OrderDAO();
orderDAO.updateAmountOfItem(Integer.parseInt(setAmountEditText.getText().toString()), itemPosition, selectedOrderId);
itemAmounts.clear();
alertDialog.dismiss();
prepareOrderData();
}
}
});
}
public void updateAmountOfItem(int amount, int itemPosition, int orderId) {
realm.beginTransaction();
Order orderToCompare = realm.where(Order.class)
.equalTo("id", orderId).findFirst();
orderToCompare = realm.copyFromRealm(orderToCompare);
RealmList<ItemAmount> itemAmounts = orderToCompare.getItemsAmounts();
ItemAmount itemAmount = itemAmounts.get(itemPosition);
itemAmount.setAmount(amount);
itemAmounts.set(itemPosition,itemAmount);
orderToCompare.setItemsAmounts(itemAmounts);
realm.insertOrUpdate(orderToCompare);
realm.commitTransaction();
}
How fix it? Because i need update only one instance, not all of them.
I take https://jsonplaceholder.typicode.com/users with asynctask but i take to use pojo object .
What should I add code between ? What line should I write and how should i write ?

Your important advice for me
Thank you!
You can easily do that with GSON and POJO
first.. you need to create several model
Post.java
public class Post
{
private String id;
private String phone;
private String username;
private String website;
private Address address;
private String email;
private Company company;
private String name;
//setter and getter
}
Company.java
public class Company
{
private String catchPhrase;
private String name;
private String bs;
//setter and getter
}
Address.java
public class Address
{
private Geo geo;
private String zipcode;
private String street;
private String suite;
private String city;
//setter and getter
}
Geo.java
public class Geo
{
private String lng;
private String lat;
//setter and getter
}
After that, json string you get from the API. parse it using Gson..
List<Post> post = new Gson().fromJson(YOUR_JSON_STRING,new TypeToken<List<Post>>() {}.getType());
I have three classes, my adapter class, Voting class, and an acitivty where my JSONrequest is as shown below.The problem is as you can see that I call my JSONrequest in my activity which will get a list of views, inside that view I have a mVote textview. In my adapter you can also see I have a likeButton when someone presses that I would like mVotes to change from 0 to 1. I get all my data from a server so I am assuming I would need to make a new request, do I need to make a new adapter to? and JSON parseing method? How do I do this?!??!
public class AdapterQuestion extends RecyclerView.Adapter<AdapterQuestion.ViewQuestion>{

"I get all my data from a server so I am assuming I would need to make a new request."
-> Actually you don't need to re-request the data from your server again. You just need to update
private ArrayList<QuestionData> data =new ArrayList<>();
on your AdapterQuestion then call AdapterQuestion.notifyDataSetChanged(); after you get a success response from onUpVote or onDownVote
"Do I need to make a new adapter to? and JSON parseing method? How do I do this?!??!"
-> No need
To change a particular ItemView in your recyclerview use this below code.
notifyItemChanged(index);
If you want to change the particular Textview in onItemclick you have to get the item position.
#Override
public void onBindViewHolder(ViewQuestion holder, int position) {
holder.answerText.setText(currentObj.getMtext());
holder.answerId.setText(currentObj.getId());
holder.mVotes.setText(currentObj.getVotes());
holder.mVotes.setTag(currentObj);
holder.mLikeButton.setTag(holder);
}
In your like button click event change the code like the below
mLikeButton.setOnLikeListener(new OnLikeListener() {
#Override
public void liked(LikeButton likeButton) {
Voting vote = new Voting();
vote.onUpVote(answerId());
final ViewQuestion holder=(ViewQuestionholder)likeButton.getTag();
currentObj co=(currentObj)holder.mVotes.getTag();
holder.mVotes.setText("16");
System.out.print("Adapter Position"+getAdapterPosition());
}
#Override
public void unLiked(LikeButton likeButton) {
Voting onDown=new Voting();
onDown.onDownVote(answerId());
final ViewQuestion holder=(ViewQuestionholder)likeButton.getTag();
currentObj co=(currentObj)holder.mVotes.getTag();
holder.mVotes.setText("14");
}
});
I have problem with sqlite database adapter in my project.I'm new to android development so I don't have much idea to how can handle this problem. I want to save user information in data base .Although no error while execution,database doesn't create? can any one help.

One Problem I see is in your insertPerson() method. Don't include the "" in the values.put()
try replacing below code
ContentValues values = new ContentValues();
values.put("PERSON_USERNAME", person.getUsername());
values.put("PERSON_HEIGHT", person.getHeight());
values.put("PERSON_WEIGHT", person.getWeight());
values.put("PERSON_AGE", person.getAge());
values.put("PERSON_GENDER", person.getGender());
values.put("PERSON_PA", person.getPa());
values.put("PERSON_BMI", person.getBmivalue());
values.put("PERSON_INTERPRETAION", person.getBmiInterpretation());
values.put("PERSON_IDEALWEIGHT", person.getIdealweight());
values.put("PERSON_DAILYCALORIES", person.getDailycalories());
with
ContentValues values = new ContentValues();
values.put(PERSON_USERNAME, person.getUsername());
values.put(PERSON_HEIGHT, person.getHeight());
values.put(PERSON_WEIGHT, person.getWeight());
values.put(PERSON_AGE, person.getAge());
values.put(PERSON_GENDER, person.getGender());
values.put(PERSON_PA, person.getPa());
values.put(PERSON_BMI, person.getBmivalue());
values.put(PERSON_INTERPRETATION, person.getBmiInterpretation());
values.put(PERSON_IDEALWEIGHT, person.getIdealweight());
values.put(PERSON_DAILYCALORIES, person.getDailycalories());
