Later sections of this chapter will cover the key features of the editing area in detail.Į – The Validation and Marker Sidebar – Android Studio incorporates a feature referred to as “on-the-fly code analysis”. Clicking on the line number, for example, displays the Go to Line dialog.ĭ – The Editor Area – This is the main area where the code is displayed, entered and edited by the user. Clicking on these values in the status bar allows the corresponding setting to be changed. This information includes the current position of the cursor in terms of lines and characters and the encoding format of the file (UTF-8, ASCII etc.). Line numbers are switched on by default but may be disabled by right-clicking in the gutter and selecting the Show Line Numbers menu option.Ĭ – The Status Bar – Though the status bar is actually part of the main window, as opposed to the editor, it does contain some information about the currently active editing session. Some typical items, among others, which appear in this gutter area are debugging breakpoint markers, controls to fold and unfold blocks of code, bookmarks, change markers and line numbers. To return the editor to the main window, click on the file tab in the separated editor window and drag and drop it onto the original editor tab bar in the main window.ī – The Editor Gutter Area - The gutter area is used by the editor to display informational icons and controls.

To detach an editor panel from the Android Studio main window so that it appears in a separate window, click on the tab and drag it to an area on the desktop outside of the main window. Navigation between files may also be performed using the Switcher mechanism (accessible via the Ctrl-Tab keyboard shortcut). Switching between files is simply a matter of clicking on the corresponding tab or using the Alt-Left and Alt-Right keyboard shortcuts. A wavy red line underneath a file name in a tab indicates that the code in the file contains one or more errors that need to be addressed before the project can be compiled and run. Clicking on this menu will drop down a list of additional open files. A small dropdown menu will appear in the far right-hand corner of the tab bar when there is insufficient room to display all of the tabs. As each file is opened, it is assigned a document tab displaying the file name in the tab bar located along the top edge of the editor window. The elements that comprise the editor window can be summarized as follows:Ī – Document Tabs – Android Studio is capable of holding multiple files open for editing at any one time. Figure 8-1, for example, shows a typical editor session with a Java source code file loaded: The Android Studio editor appears in the center of the main window when a Java, Kotlin, XML or other text based file is selected for editing. Experienced programmers will find that some of these features are common to most code editors available today, while a number are unique to this particular editing environment. While not an exhaustive overview of the features of the Android Studio editor, this chapter aims to provide a guide to the key features of the tool.

As will become evident in this chapter, these are just a few of the areas in which the Android Studio editor excels. Today the usefulness of a code editor is generally gauged by factors such as the amount by which it reduces the typing required by the programmer, ease of navigation through large source code files and the editor’s ability to detect and highlight programming errors in real-time as the code is being written. The modern code editor needs to go far beyond the original basics of typing, deleting, cutting and pasting. It should come as no surprise that the majority of a developer’s time spent using Android Studio will typically involve editing code within the editor window.
