In these functions, canvas
is utilized as a part of the Jetpack Compose library in Android. Here, canvas
is used to display a custom progress indicator in the user interface.
The CustomProgressIndicator
function defines and draws a custom progress indicator with the help of canvas
and other Jetpack Compose tools. In this function, canvas
is indirectly used via drawBehind
to draw two concentric circles using the backgroundIndicator
and foregroundIndicator
functions. These two circles represent the background and foreground progress indicators, respectively.
The backgroundIndicator
and foregroundIndicator
functions also use canvas
to draw the circles using the drawArc
functions. These functions draw different parts of the circles with specified angles and thickness.
In general, canvas
is used in these functions as a means to draw graphical shapes in the user interface.
