Multiple layout setVisibility wont show correct layout after getting pressed on certain layout

I have a layout in which there are several other layouts by including in XML, I add some textviews as buttons to change the view layouts from one layout to another.
I display each layout with the setVisibility method between layouts, with setOnClickListener in the textview.
The problem is just after finishing displaying the "profile" layout and trying to display the "about us" layout, the system displays a "profile" layout instead of the "about us" layout.
Here is myJava
public class SettingMenu extends AppCompatActivity {
View userProfile, settingLayout, userFavorite, UserEditProfile, aboutUS, contactUS, ProgressBar;

If RecyclerView scrolls, then item id changes. How to resolve this?

This is my PDFListAdapter class method. I have downloaded file locally and save on Sqlite database. But if I scroll my RecyclerView, then I am having different item id. If not scroll RecyclerView then item id is perfect.
The problem is when I scroll down the RecyclerView the item id changes. That is, I can fit one item on the screen at once. When I scroll to the second item, it saves different file and opens different.

I have modified your onBindViewHolder function. The changes are following.
Declared the pdfList variable as final and used it everywhere. It is not necessary to get the pdfList from the pdfModelClasses, each time you use it.
The holder variable is removed, as it is not actually necessary. The holder1 is used everywhere.
There are some changes with the visibility of the buttons. Check holder1.imgDownloadNote.setOnClickListener.
I have found no other problem in your onBindViewHolder. Please let me know if the modified code works.

The problem is when I get the data to send, in the for the JSON for send are ok, but in the getparms() this only set the last JSON for send, and send many times of the total array

Call number when click list view item

I have a contact list activity but want to add some functionality so that when you click on a contact it will begin calling their phone number. I have tried this code snippet but nothing happens when I tap on a contact:
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:" + currentContact.getPhone()));
if (ActivityCompat.checkSelfPermission(context, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
return;
}
try{
((Activity) context).startActivity(callIntent);
}catch (Exception e){
e.printStackTrace();
}

pls comment line LoginBean loginBean = new LoginBean(); then try .
try this code
private void getLogin(JSONObject response) {
LoginBean loginBean=null;
if (response != null){
try {
loginBean = new LoginBean();
JSONObject jsonObject = response.getJSONObject("data");
loginBean.setUser_id(jsonObject.getString("user_id"));
loginBean.setFull_name(jsonObject.getString("full_name"));
loginBean.setDisplay_name(jsonObject.getString("display_name"));
loginBean.setUser_image(jsonObject.getString("user_image"));
loginBean.setGender(jsonObject.getString("gender"));
loginBean.setAuthorization_key(jsonObject.getString("authorization_key"));
// signUpArrayList.add(signUpBean);
} catch (JSONException e) {
e.printStackTrace();
}
// dataBean.setSignUp(signUpArrayList);
}
Toast.makeText(getApplicationContext(),"Hello"+loginBean.getFull_name(),Toast.LENGTH_LONG).show();
