10## How to Use
11
12- Use a progress bar when your users need to wait, for example, for content loading or file transfer through Bluetooth. The loading process or operation progress is displayed so that they can know the task status.
13
14- Generally, use a rectangular bar as the progress bar.
15
16- Design progress bars based on the use scenario. Try to integrate progress bars into the UI content or operation elements to minimize the use of progress bar dialogs, making users feel less complicated.
17
18- In the dialog, if the waiting time is too long, provide a **Hide** button to hide the progress bar and wait the operation to be completed at the background. Display the hidden progress bar in the notification bar.
