Click the Sync At this point switch to revise your panels.

3. Identify Templates

The activity_main.xml data, and that is already sure to MainActivity , defines the contents of your house screen of the software. This means that, it will eventually represent the chatroom.

Similar to other-group talk apps you can get today, our Firebase chatroom Android app has all of the following UI properties:

  • an email list that shows these team talk communications in chronological arrange
  • an insight industry where in actuality the owner can input the latest message
  • a switch the consumer can hit to create the content

For that reason, activity_main.xml must have a ListView , an EditText , and a FloatingActionButton . After inserting all of them inside a RelativeLayout widget, their layout XML will want to look like this:

Observe that i have placed the EditText widget inside a TextInputLayout widget. Accomplishing this contributes a floating tag to the EditText , which is crucial if you wish to adhere to the advice of material build.

Given that the format of your home test is ready, you can start working on promoting a structure towards talk messages, which is objects inside the ListView . Begin by producing an innovative new format XML file called information.xml, whose core aspect is RelativeLayout .

The structure is required to have TextView widgets to show the chat content’s articles, some time it actually was sent, as well as writer. Your free to stick them in virtually any purchase. Here’s the layout i’m going to be utilizing:

4. Manage Individual Authentication

Permitting users to anonymously article messages for the chatroom would be a rather bad tip.

Or else, it must reroute the person to either a sign-in display or a sign-up screen. With FirebaseUI, making those window screens usually takes a lot less code than you may think of.

In the onCreate() approach to MainActivity , find out if an individual is already signed in. To work on this, check if the current FirebaseUser subject will never be null . Whether it’s null , make sure that you make and assemble an Intent subject that opens up a sign-in actions. To do so, make use of SignInIntentBuilder school. When the objective is prepared, make sure you start the sign-in activity by using the startActivityForResult() technique.

Note that the sign-in actions additionally let new users to subscribe. Consequently, it’s not necessary to write any additional code to look at cellphone owner registration.

Put in here laws within the onCreate() means:

Clearly from inside the previous code, if your cellphone owner is already closed in, we for starters showcase a Toast lively the individual, and then label a method named displayChatMessages. At the moment, simply generate a stub for it. We are going to staying putting signal this later.

Once the consumer offers signed in, MainActivity will get an outcome by using a plan . To deal with it, you should override the onActivityResult() method.

If outcome’s rule is RESULT_OK , it signifies the consumer offers signed in successfully. In this case, make sure that you label the displayChatMessages() means again. If not, contact finish() to shut the software.
