In this app I save products in a sqlite database. Could you help me understand why I can’t see the image when I want to edit a product? I can see it when I add it but not when I click on product to edit it.

The link to the full code is : https://drive.google.com/open?id=1aQFcWHinIqqXHbTyssfPYTD20o9E2piA
and if you can’t find the java files here they are: https://drive.google.com/drive/folders/1VKp0CoJlJssSdKzK4ctk26KFY0_xIDzU?usp=sharing
In your onLoadFinished you assume mPictureURI is set and is not empty.
Now you have set a listener on mProductImageView for changes. No matter what you write/set down below the mProductImageView finally the in the listener it was set back to mPictureURI which was empty hence showing an empty image space.
Please have a look at the code below(also verified that it works).
#Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
if (cursor == null || cursor.getCount() < 1) {
return;
}
if (cursor.moveToFirst()) {
int nameColumnIndex = cursor.getColumnIndex(ProductContract.ProductEntry.COLUMN_PRODUCT_NAME);

int mailColumnIndex = cursor.getColumnIndex(ProductContract.ProductEntry.COLUMN_PRODUCT_SUPPLIER_MAIL);
int pictureColumnIndex = cursor.getColumnIndex(ProductContract.ProductEntry.COLUMN_PRODUCT_PICTURE);
String name = cursor.getString(nameColumnIndex);

int quantity = cursor.getInt(quantityColumnIndex);

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.

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.

Seems simple, but I can't get it to work. I have a public class string variable that should change within a if or switch statement. I haven't declared the variable inside the statement so it should change given the scope, no? But it only reads "FROM" and when I do go to change it in the if statement that applies, it does change to "TO" but only in that instance and reverts back to "FROM". I would pass it along the methods, but the full code is more cluttered and I don't think it's possible to do so.

The reason the code keeps reverting is because the call to readImage() is in onActivityResult() which recreates the activity when called. So basically, you are getting a fresh object, and the onTypeText() is reinitialized. onActivityResult() is basically a callback from your previous activity.
Your onClick() is not being called due you don't assign clicklistener to R.id.faboptions_favorite and the other View
in onCreate add :
findViewById(R.id.faboptions_favorite).setOnClickListener(this);
and same for the other view.

First of all I would like to tell you that you should not rely on Timer for your code to run repetitively because timer is destroyed by system after sometime , i hope u would have realized this bug. And for your problem you should create a hashmap to know weather the foreground activity is already accessed by user or not by verifying the password.
