2. Add Some Dependencies

We’ll use two libraries within Android os talk software signal visualize: FirebaseUI along with Android design and style service archive. As a result, start the build.gradle document from the application module and use here make dependencies to it:

Hit the Sync nowadays switch to revise the project.

3. Determine Designs

The activity_main.xml file, which can be already certain to MainActivity , describes the contents of the home display on the software. This means that, it is going to portray the chat room.

Like the majority of other-group cam apps available today, the Firebase chatroom Android os app may have the next UI elements:

  • an inventory that displays every collection chat communications in chronological purchase
  • an input discipline where in fact the cellphone owner can input a new content
  • a switch the person can click to write the message

As a result, activity_main.xml will need a ListView , an EditText , and a FloatingActionButton . After placing all of them inside a RelativeLayout widget, your very own design XML will want to look along these lines:

Observe that I’ve put the EditText widget inside a TextInputLayout widget. Doing so adds a floating name to the EditText , which is crucial when you need to follow the instructions of information layout.

Seeing that the model of the property screen is prepared, we’re able to start working on developing a structure for its cam information, which will be merchandise within ListView . Start with creating a fresh format XML file labeled as information.xml, whose root feature was RelativeLayout .

Usually, it must reroute the consumer to either a sign-in monitor or a sign-up screen. With FirebaseUI, developing those window screens produces less code than you possibly might figure.

Within the onCreate() technique of MainActivity , check if an individual has already been signed in. To achieve, verify that today’s FirebaseUser thing just isn’t null . When it is null , you have to create and configure an Intent target that starts a sign-in action. To accomplish this, use the SignInIntentBuilder course.

For the moment, only develop a stub because of it. We’re going to get including laws this afterwards.

After the customer enjoys closed in, MainActivity will get an outcome as a motive . To carry out they, you should bypass the onActivityResult() process.

When the effect’s code try RESULT_OK , it is meaning the person offers finalized in successfully. If that’s the case, make sure that you call the displayChatMessages() process once again. Normally, call finish() to close off the application.
