Refer to this Material Design page for a clearer explanation of how sp/dp works. The unit we use for font size is sp (this is the dp of font sizing). The android:textSize attribute allows you to specify a font size. There are some new ones to check out here, too. You should recognize some attributes, such as margin, text, or identifiers assigned to these elements. Remember that the identifiers are mandatory - they allow you to reference the elements from code and update them dynamically. To do this, open the file activity_game.xml located in the res / layout directory, and change the code as follows: The interface of this new Activity will contain the following elements:įour possible answers, each represented by a button Leave the following settings:īackwards Compatibility (App Compat) is selectedĬlick the Finish button.` In this window, you can configure the Activity name and layout file. We know this Activity will handle the game logic, so we will call it GameActivity. This window allows you to configure the Activity's name and its layout file. Create an Activity file.Īndroid Studio displays a new window. Right-click on it and select New > Activity > Empty Activity. Position your cursor in your project tree and hover over the directory which contains the MainActivity class we created in the previous chapter. For example: Take a look at our amazing app! Creating a New Activity Create the Activity FilesĪs a reminder, an Activity is usually composed of a Java class and an associated layout file. Each question will have four possible answers. It's very simple: TopQuiz will ask a series of four questions, chosen randomly from a set. The first Activity will launch this new Activity when the user clicks on the play button. In this next part, we will create a second Activity which displays the game content. In the first part of this course, we created an Activity, which allowed us to recover a user's first name and start a game.
