1. Create a navigation graph

Navigation occurs between your app’s destinations — that is, anywhere in your app to which users can navigate. These destinations are connected via actions.

A navigation graph is a resource file that contains all of your destinations and actions. The graph represents all of your app’s navigation paths.

Figure 1 shows a visual representation of a navigation graph for a sample app containing six destinations connected by five actions. Each destination is represented by a preview thumbnail, and connecting actions are represented by arrows that show how users can navigate from one destination to another.

  1. Destinations are the different content areas in your app.
  2. Actions are logical connections between your destinations that represent paths that users can take.

To add a navigation graph to your project, do the following:

  1. In the Project window, right-click on the res directory and select New > Android Resource File. The New Resource File dialog appears.
  2. Type a name in the File name field, such as “nav_graph”.
  3. Select Navigation from the Resource type drop-down list, and then click OK.

When you add your first navigation graph, Android Studio creates a navigation resource directory within the res directory. This directory contains your navigation graph resource file (nav_graph.xml, for example).

2. Navigation Editor

After adding a graph, Android Studio opens the graph in the Navigation Editor. In the Navigation Editor, you can visually edit navigation graphs or directly edit the underlying XML.

  1. Destinations panel: Lists your navigation host and all destinations currently in the Graph Editor.
  2. Graph Editor: Contains a visual representation of your navigation graph. You can switch between Design view and the underlying XML representation in the Text view.
  3. Attributes: Shows attributes for the currently-selected item in the navigation graph.

Click the Text tab to see the corresponding XML, which should look similar to the following snippet:

The <navigation> element is the root element of a navigation graph. As you add destinations and connecting actions to your graph, you can see the corresponding <destination> and <action> elements here as child elements. If you have nested graphs, they appear as child <navigation> elements.
