NotifyDataSetChanged Recycler view : Cannot call this method while Recycler

I'm making a chat app. I have a recycler view. I use Picasso to download the images of the user and the friend he is chatting with. To not download the image for every message, when I download the first image I just put it into a bitmap and use it every time.
PROBLEM: I can't call NotifyDataSetChanged. I have tried every possible thing I've found on the net.
ERROR :
Cannot call this method while RecyclerView is computing a layout or scrolling android.support.v7.widget.RecyclerView
I have to "manually" refresh the view so that the images are loaded. No problem for the text.
It runs with the Handler but it doesn't even go in the function (so the view isn't refreshed).
Here is my code (everything works except this notifydatasetchanged)
public class ChatActivity extends AppCompatActivity {

It is because you're calling notifyDataSetChanged inside your onBindViewHolder like this:
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
...
((ItemMessageFriendHolder) holder).avata.setImageBitmap(BitmapFriend);
new Handler().post(new Runnable() {
#Override
public void run() {
notifyDataSetChanged();
}
});
...
}
You shouldn't force the Adapter to refresh itself before it isn't finished binding the view yet.
So, you need to remove the following code from your onBindViewHolder:
new Handler().post(new Runnable() {
#Override
public void run() {
notifyDataSetChanged();
}
});
then just call notifyDataSetChanged() when you need it. For example, when your dataset is changed.

Try this.
dialeecyclerView.post(new Runnable()
{
#Override
public void run() {
myadapter.notifyDataSetChanged();
}
});

API successfull called, but not displayed

i am trying to call local API server using retrofit, in my Logcat shows that the API success called, but in my app there is nothing displayed. how i can fix this issue? and here is my code :
interface.java :
public interface Service {
#GET("vocabulary/id/*")
Call<APIResponse<List<VocabMaster>>> getVocabMaster();
}
Vocab Master.java to collect data from API :
public class VocabMaster implements Serializable {
private BigDecimal vocab_id;
private String hanzi_t;
private String hanzi_s;
private String pinyin;
private BigDecimal level_id;
private List<VocabMeaning> meaning;
public BigDecimal getVocab_id() {
return vocab_id;
}
public void setVocab_id(BigDecimal vocab_id) {
this.vocab_id = vocab_id;
}
public String getHanzi_t() {
return hanzi_t;
}
public void setHanzi_t(String hanzi_t) {
this.hanzi_t = hanzi_t;
}
public String getHanzi_s() {
return hanzi_s;
}
public void setHanzi_s(String hanzi_s) {
this.hanzi_s = hanzi_s;
}
public String getPinyin() {
return pinyin;
}
public void setPinyin(String pinyin) {
this.pinyin = pinyin;
}
public List<VocabMeaning> getMeaning() {
return meaning;
}
public void setMeaning(List<VocabMeaning> meaning) {
this.meaning = meaning;
}
public BigDecimal getLevel_id() {
return level_id;
}
public void setLevel_id(BigDecimal level_id) {
this.level_id = level_id;
}
#Override

}
}
And this is MainActivity.java :

i did some changes in your code... use this
private VocabAdapter ar;
private void initReligiVideo() {
LinearLayoutManager layout = new LinearLayoutManager(this);
layout.setOrientation(LinearLayoutManager.HORIZONTAL);
rvReligiVideo.setLayoutManager(layout);
ar = new VocabAdapter(vocabMasters);
rvReligiVideo.setAdapter(ar);
}
private void loadReligiVideo() {
Call<APIResponse<List<VocabMaster>>> call = ServicesFactory.getService().getVocabMaster();
call.enqueue(new Callback<APIResponse<List<VocabMaster>>>() {
#Override
public void onResponse(Call<APIResponse<List<VocabMaster>>> call, Response<APIResponse<List<VocabMaster>>> response) {
if (response.isSuccessful() && response.body().isSuccessful()) {
List<VocabMaster> data = response.body().data;
if (data != null) {
ar.setVocoList(data);
}
} else {
Toast.makeText(MainActivity.this, response.errorBody().toString(), Toast.LENGTH_LONG).show();
}
}
#Override
public void onFailure(Call<APIResponse<List<VocabMaster>>> call, Throwable t) {
Toast.makeText(MainActivity.this, t.getLocalizedMessage(), Toast.LENGTH_LONG).show();
}
});
}
Add this method in your adapter Class
public void setVocoList(List<VocabMaster> list){
if(list!=null)
data=list;
notifyDataSetChanged();
}

Do not change adapter's list when you have new list.
//incorrect except that the adapter is first time set to recyclerview and setVocoList is called before recyclerview.setAdater
public void setVocoList(List<VocabMaster> list){
if(list!=null)
data=list;
notifyDataSetChanged();
}
//correct
private List<VocabMaster> datas = new ArrayList()
public void setVocoList(List<VocabMaster> list){
if(list==null) return;
datas.clear();
datas.addAll(list);
notifyDataSetChanged();
}

This is the JSON response I am getting after posting the Review
E/final Json: {"studentId":1,"courseId":1,"review":"Hellooooo","ratings":3}
E/Json response: {"success":true,"msg":"Your review has been added successfully","data":{"reviewsId":18}}

private ArrayList<Review> getDataSet(JSONArray array) {

Review obj = new Review(object.getInt("studentId"),object.getInt("courseId"),object.getString("Review"),object.getLong("rating"));
results.add(i,obj);
}
catch (Exception e){
e.printStackTrace();
}
}
return results;
}
try to change your getDataSet function with above code and check with debug point if you get any problem in some line. feel free to ask further will help you
EDIT:
You need to change your Pojo class of Review also. Because in JSON response you are not getting userId and reviewId. Hope you understand

First page of ViewPager not getting rendered

I am using a ViewPager to be able to swipe between views. The problem that I am facing is, the first page does not render properly(only the static members from layout file get rendered), but the second page and further pages are rendered properly. Also, when I go to third or later page and then come swiping back to the first page, it gets rendered perfectly.
I know that ViewPager loads the first page as well second page in the beginning and does the same for every next page. Is this the reason why my first page is not rendered properly? I am making a network call on each page and the data returned is being displayed on the page.

just add this method to your Class
#Override
public int getItemPosition(Object object) {
return POSITION_NONE;
}
it will render every time when you enter to particular layout. this is the override method of pagerAdapter.
