android - create alpha animation but not fill until button click -

i want set alpha view alphaanimation(1.0f, 0.15f); , click again reset alpha use code below:

button.setonclicklistener(new view.onclicklistener() {              @override     public void onclick(view v) {         if(fadeinout) {              expcontrol.startanimation(set1);             seekzoom.startanimation(set1);             btnrotate.startanimation(set1);              fadeinout=false;          } else {              expcontrol.startanimation(set);             seekzoom.startanimation(set);             btnrotate.startanimation(set);             fadeinout=true;          }      } }); 

and animation set1 , set2 in below

private animation fadein(int t) {     alphaanimation localalpha = new alphaanimation(1.0f, 0.15f);     localalpha.setduration(800l);     localalpha.setstartoffset(100l);     localalpha.setfillafter(false);     localalpha.setinterpolator(new accelerateinterpolator());      return localalpha; }  private animation fadeout(int t) {     animation fade;     fade = new alphaanimation(0.15f, 1.0f);     fade.setduration(800l);     localalpha.setfillafter(false);     fade.setinterpolator(new accelerateinterpolator());     return fade; } 

but when animation finish reset view fill alpha want alpha change button click

and not working setalpha(). want create app sdk 8 , above.
