This is my SignUp.class I want to upload a profile picture drawable into User class in the profilepic column and a profile cover in the profilecover column
R.drawable.avatar_circle is the profile picture drawable and R.drawable.drawer_header_light is the drawable for the profile cover.

First you should get the drawable and store it as a Bitmap:
Bitmap profilePic = BitmapFactory.decodeResource(context.getResources(), R.drawable.avatar_circle);
Bitmap profileCover = BitmapFactory.decodeResource(context.getResources(), R.drawable.drawer_header_light);
Then when you're signing up the user:
ParseGeoPoint currentLocation = new ParseGeoPoint(49.2827, -123.1207);;
User.setUsername(username);
User.put("status", getResources().getString(R.string.default_status));
User.setEmail(email);
User.setPassword(password);
User.put("profilepic", profilePic);
User.put("profilecover", profileCover);
User.put("Location", currentLocation);

when i filter recyclerview it shows Not found .My Searchview not working.when i run the code its result in Not Found i think there is problem in onQueryTextChange
myfilter function also did not work
#Override
public boolean onQueryTextSubmit(String query) {
Toast.makeText(SecondActivity1.this, "Name is : " + query, Toast.LENGTH_SHORT).show();
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
final List<DatabaseModel> filteredModelList = filter(dbList, newText);
if (filteredModelList.size() > 0) {
// Toast.makeText(SecondActivity1.this, "Found", Toast.LENGTH_SHORT).show();
recyclerAdapter.setFilter(filteredModelList);
return true;
} else {
Toast.makeText(SecondActivity1.this, "Not Found", Toast.LENGTH_SHORT).show();
return false;
}
private List filter(List models, String query) {
query = query.toLowerCase();
recyclerAdapter.notifyDataSetChanged();
final List<DatabaseModel> filteredModelList = new ArrayList<>();
// mRecyclerView.setLayoutManager(new LinearLayoutManager(SecondActivity1.this));
// mRecyclerView.setAdapter(RecyclerAdapter);
for (DatabaseModel model : models) {
final String text = model.getName().toLowerCase();
if (text.contains(query)) {
filteredModelList.add(model);
}
}
return filteredModelList;
//
}
here is filter method which recieve parameter(dblist,newtext) filter method recieves these method when i use toast its show that it takes newText But didnot filter this.i checked many sites but this is same in many sites points.when i enter name toast shows name which i enter but it did not filter

this is my recyclerAdapterCode.i also used Recycleradapter.setFilter(filterModeList) method but it did not work for me.i think in my set filter method error which i did not solve yet.
. But when I clear the search widget I don't get the full list instead I get the empty RecyclerView.
When I click on my app first button it stopped working

I have a TabPane where users enter/edit data on each tab and can freely switch between tabs without having to save changes before switching to a new tab. One tab has a TableView, and I'd like to prevent users from leaving that tab if they enter invalid data. My original approach was along the same lines as this question, which does not quite work - the tab is not reliably changed back. I liked James_D's answer and tried to implement something similar. However, most of the time the data being entered into a table is optional, so disabling other tabs until a user enters data is not an option.
What I ultimately did was extend TableColumn to add a BooleanProperty 'invalid' which I then bind to Tab's disableProperty. In that column's commit event, I validate the new value and, if it doesn't pass, set invalid = true, which disables the appropriate tab. This also does not quite work. I have custom table cells that commit edits on loss of focus. If focus is lost to clicking a different tab, the commit event is too late - the tab is first selected, then disabled. I've been wracking my brain for a workaround, but am out of ideas. If anyone has any suggestions, I would really appreciate it!

If you create your observable list with an extractor, for example:
ObservableList<Person> data = FXCollections.observableArrayList(person ->
new Observable[] { person.lastNameProperty() });
then the list will fire update notifications any time any of the specified properties change in any of the elements (in this case, any time the lastName changes on anything in the list).
So now you can create a binding for invalid:
BooleanBinding invalid = Bindings.createBooleanBinding(
() -> data.stream().anyMatch(person -> person.getLastName().isEmpty()),
data);
And then you can just observe that binding:
invalid.addListener((obs, wasInvalid, isNowInvalid) -> {
if (isNowInvalid) {
// show alert, etc...
}
});
or disable a node by binding to it:
someNode.disableProperty().bind(invalid);
You could similarly bind this invalid property in your TableColumn subclass (if you still need that) to this binding.

Here i did a view reusing thats why it does auto checking checkboxes, just remove the braces and else part from getView this solved my problem
