Seven styles of Android progress bar

When an application is executed in the background, there will be no information on the foreground interface. At this time, the user does not know whether the program is executing, how the execution progress is, whether the application encounters error termination, etc. at this time, the progress bar needs to be used to prompt the user about the execution progress of the background program. Android system provides two types of progress bar styles: progress bar style horizontal and progress bar style large. Progress bars are useful. For example, when an application loads resources and network connections, you can prompt the user to wait. This kind of progress bar only represents the execution of a part of the application, while the execution of the whole application can display a progress bar through the application title bar, which requires setting the display style of the window first "requestWindowFeature(Window.FEATURE_PROGRESS)"。
