I'm trying to use Saripaar Validation on my project, but it's throwing the following error:
java.lang.IllegalStateException: No rules found. You must have at
least one rule to validate. If you are using custom annotations, make
sure that you have registered them using the 'Validator.register()'
method.
My architecture separates the responsibility for handling the view into a class, for example for LoginActivity I have LoginView, which is where I handle my view logic like ButterKnife injection, event listening, etc. In this class I have my annotated fields.My LoginView looks like this:

From what I'm guessing, the library is trying to find these fields on my Activity, and since they're not there, then it's throwing this error.
Is there a way use this library accordingly to the architecture I'm handling?
use validator = new Validator(this) in place of validator = new Validator(context);

I have an Activity with a RecyclerView which display Livedata from a room database.
My aim is to start a new Activity with more data from the room database when the user is clicking on the corresponding item in the RecyclerView.
For that I overwrote the onClick() method in the adapter of the RecylcerView. Each object of the RecyclerView has a Id, I need that Id to get the corresponding data from the database. So I passed the Id from the Adapter to the Activity.
To search an element by Id in the database that I need the ViewModel object in the MainAcitivty. It is initialized in the onCreate() of the Activity. The method I called in the Adapter is outside the onCreate() and I get a null object reference exception when I try to use it.
How can I use the ViewModel outside of the onCreate() method of the Activity? Or is there another way to search for the element in the database?
Thank you!
The Adapter class:
In the onClick() method is the relevant part.

The thing you need to do is to use a call back to send position back to activity.
To make sure that view position is correct you need to override 3 functions in RecyclerView Adapter:
#Override
public int getItemCount() {
return filteredUsers.size();
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public int getItemViewType(int position) {
return position;
}
For the Callback just create an Interface:
public interface AdapterListener {
void onClick(int id);
void onClick(ViewModel object);
}
Make a method in your Recycler Adapter:
private AdapterListener adapterListener;
public void setAdapterListener(AdapterListener mCallback) {
this.adapterListener = mCallback;
}
Implement this Interface on your Activity then you will get both methods of the interface.
public class MainActivity extends AppCompatActivity implements AdapterListener{
Register the listener by calling the setAdapterListener method in your activity after the initialization of the RecyclerView
adapterObject.setAdapterListener(MainActivity.this);
Then the last thing you need to do is call interface method in your item onClickListener, where u can either pass the complete model or just the id of the model
adapterListener.onClick(modelObject.getId());
OR
adapterListener.onClick(modelObject);
I am using a Google library called play-services-plugins to include Open Source Notices on my app.
I could implement it with no problem, but I have no idea how I can style the activity that displays the license.
In my code, I start the activity by calling startActivity(Intent(this, OssLicensesMenuActivity::class.java))
Since OssLicensesMenuActivity is an Activity class, I manage to style like this:
styles.xml:
<style name="LicensesTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/colorPrimaryDark</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
AndroidManifest.xml:
<activity
android:name="com.google.android.gms.oss.licenses.OssLicensesMenuActivity"
android:theme="#style/LicensesTheme" />
This works like a charm, but this activity just displays all the libraries I'm using.
There is a second activity that displays the licence and that's the one I can't figure out how to style. The problem I'm facing is that the code from OssLicensesMenuActivity is obfuscated and I can't find the name and package of the activity class I want to style.
Anyone knows how I can solve this problem?
Just to it's easier to check, the obfuscated code from OssLicensesMenuActivity is the following:

Just do the same for "OssLicensesActivity" as you did for "OssLicensesMenuActivity" in the Manifest:
<activity android:name="com.google.android.gms.oss.licenses.OssLicensesActivity"
android:theme="#style/LicensesTheme" />
This should style the "second activity that displays the licence".
I have some code whose function is to show the name and age of a user in a RecyclerView but that same RecyclerView is always returning null no matter where I put it.
I tried to put getUserInfo() in onStart() and it didn't work.
I've already looked in other posts in StackOverflow and it still hasn't worked.

The first, you don't need to set adapter multiple time, only set adapter at the first time in your method initView().
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity().getApplicationContext());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
lvToday.setHasFixedSize(true);
lvToday.setNestedScrollingEnabled(false);
if(mTrainingDTO == null) {
mTrainingDTO = new ArrayList<>();
}
if(null == mTrainingDTOAdapter ) {
mTrainingDTOAdapter = new RecyclerAdapter(getActivity(), mTrainingDTO, FragmentTapNew.this);
}
lvToday.setAdapter(mTrainingDTOAdapter);
Thread t = new Thread(new Runnable() {
#Override
public void run() {
today();
}
});
t.start();
After that, you don't need to call lvToday.setAdapter(mTrainingDTOAdapter);
many times. Just call mTrainingDTOAdapter.notifyDataSetChanged(); if having any changes in your data mTrainingDTO.
The errorlog - error:No adapter attached; skipping layout indicates that you've attached LayoutManager but you haven't attached an adapter yet, so recyclerview will skip layout. I'm not sure but, in other words recyclerView will skip layout measuring at the moment.
to prevent this errorLog Try to set an adapter with an empty dataSet i.e. ArrayList or
Attach LayoutManager just before you are setting your adapter.
Try this,
private void initViews() {
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity().getApplicationContext());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
LinearLayoutManager mLinearLayoutManager = new LinearLayoutManager(getActivity());
lvToday.setLayoutManager(mLinearLayoutManager);
lvToday.setHasFixedSize(true);
lvToday.setNestedScrollingEnabled(false);
Thread t = new Thread(new Runnable() {
#Override
public void run() {
today();
}
});
t.start();
}
Hi I'm trying to combine 2 projects
1. that tells me wen button on arduino pressed
2. make a call on android
what im trying to do is when button pressed on arduino make a call..
but with no luck :(

Your call() function is declared in your activity, but you're trying to access it in your ButtonView class. Try moving it into ButtonView (copy & paste).
