my question how partially fill star in android?

i want fill option not half fill star.

and also, if consider full star length 100%.

and have fill star length of 20% or have fill star length of 50% or have fill star length of 70%.

any fill values fill star.

your path object here 'outline' of star. if want paint it, set style fill , stroke. can't partially paint it. need create path object , set paint fill , draw it. ideally draw outline , fill separately.

it's simple. have done half of it. can reuse calculation did outline path fill path.

update: if rating kind of thing, need dynamically increase or decrease filling. if that's case. draw fill rectangle, , clip using star outline. need increase or decrease width of rectangle.

update: if it's partial picture want, have create bitmap of picture , draw using drawbitmap(). clip region make it's partially filled, using clipregion().
