1: Handle Consumer Sign-In

In that case, the application is going forward and show the items in the talk area. Or else, it must reroute an individual to either https://besthookupwebsites.net/dog-dating/ a sign-in screen or a sign-up display. With FirebaseUI, promoting those screens takes way less code than you might envision.

Inside onCreate() way of MainActivity , find out if the user is signed in. To achieve this, verify that the existing FirebaseUser item just isn’t null . If it’s null , you need to make and configure an Intent item that starts a sign-in activity. To achieve this, utilize the SignInIntentBuilder lessons. When the purpose is prepared, you must launch the sign-in activity by using the startActivityForResult() method.

Observe that the sign-in task also enables new users to register. Therefore, you don’t need to create any further code to handle consumer subscription.

Clearly in preceding laws, in the event that user is finalized in, we first highlight a Toast welcoming the consumer, following phone a way named displayChatMessages. For the present time, only establish a stub because of it. We will feel adding laws to it after.

Once the individual enjoys finalized in, MainActivity will get an end result in the form of a purpose . To carry out it, you should override the onActivityResult() technique.

If the result’s rule was RESULT_OK , it means the user features finalized in effectively. If that’s the case, you need to contact the displayChatMessages() approach again. Usually, call finish() to shut the app.

2: Manage User Sign-Out

By default, FirebaseUI uses Smart Lock for Passwords. Therefore, when the consumers register, they’ll stay signed in even when the application are restarted. Permitting the people to signal completely, we’re going to today add a sign-out option to the overflow diet plan of MainActivity .

Generate another selection reference document known as main_menu.xml and add an individual items to they, whoever title feature is set to signal on. The contents of the document need to look similar to this:

To instantiate the menu source inside MainActivity , override the onCreateOptionsMenu() technique. Subsequently phone the inflate() method of the MenuInflater item.

After that, override the onOptionsItemSelected() approach to manage click events in the selection object. In the approach, you are able to contact the signOut() approach to the AuthUI class to sign the consumer down. Since sign-out procedure try accomplished asynchronously, we are going to also add an OnCompleteListener to it.

As soon as user enjoys closed aside, the software should shut instantly. This is why the reasons why you discover a phone call for the finish() process into the rule above.

5. Make An Unit

In order to keep the chat messages when you look at the Firebase real-time databases, you have to build a product on their behalf. The layout associated with the chat message, which we created before within tutorial, possess three vista. To be able to populate those horizon, the design as well need at the least three industries.

Generate another coffee lessons also known as ChatMessage.java and create three affiliate factors to it: messageText , messageUser , and messageTime . Furthermore, put a constructor to initialize those variables.

To help make the model compatible with FirebaseUI, you must also add a standard constructor to they, together with getters and setters for all the associate factors.

6. Post A Cam Information

Inside listener, it is vital that you first bring a DatabaseReference item utilising the getReference() approach to the FirebaseDatabase course. You can then name the push() and setValue() strategies to include latest cases of the ChatMessage course towards real-time databases.

The ChatMessage circumstances must, without a doubt, end up being initialized with the contents of the EditText while the show title from the currently signed-in consumer.
