android - Is there a way to use ValueAnimator with a starting point mid-way within the range? -

-

i have image , wish animate alpha in repeating loop between transparent , visible. easy using valueanimator this:

  mvalueanimator1 = valueanimator.offloat(1.0f, 0f);   mvalueanimator1.setrepeatmode(valueanimator.reverse);   mvalueanimator1.setrepeatcount(valueanimator.infinite);   mvalueanimator1.addupdatelistener(new valueanimator.animatorupdatelistener() {     @override     public void onanimationupdate(valueanimator animation) {         float value = ((number) animation.getanimatedvalue()).floatvalue();         imageview.setalpha(value);

that's straightforward if starting alpha image should 1, , straightforward if starting alpha image should 0.

but in case want starting alpha value within range specified within offloat() i.e. if starting alpha should 0.75 want animation loop this:

   0.75, 0.85, 0.95, 1.0, 0.95, 0.75, 0.5, 0.3, 0.1, 0.0, 0.1, 0.2, 0.4, 0.6, 0.8 etc

(values representative convey general idea).

is there way of using valueanimator range specified such 0 - 1 starting point mid way within specified range?

you use mvalueanimator1.setcurrentfraction(startingalpha) set starting point, setcurrentfraction() added in api 22.

another approach might use animatorset consisting of 2 valueanimator objects, first 1 offloat(1.0f) (the value want animation head first), followed valueanimator infinitely repeats between 1.0 , 0.0.
