The use of the Navigationview of Android design

The following explains the use of the tablayout under the design package, which will bring Navagationview and drawlayout as well as toolbar linkage.

Navigationview is easier to implement by providing the framework needed for drawer navigation, and it can directly generate navigation elements directly from menu resource files. Use Navigationview as a content view for drawerlayout. Navigationview handles the relationship with the status bar and ensures that the navigationview is properly interacting with the status bar on the api21+ device.

The following code is modified based on the preceding code.
