java - My code receives the error "The specified child already has a parent. You must call removeView() on the child's parent first." -

as title reads, getting error in logcat when run app. code written after error occured:

public void coinanim1() {      relativelayout rl = (relativelayout) findviewbyid(r.id.mainlayoutid);     imageview coin1 = new imageview(this);      relativelayout.layoutparams params = new relativelayout.layoutparams(30, 40);     params.leftmargin = 50;      coin1 = (imageview) findviewbyid(r.id.coinid);      animation coinfall1 = animationutils.loadanimation(this,             r.anim.coinanimation);     coin1.startanimation(coinfall1);      rl.addview(coin1, params);  }  public void coinanim2() {      relativelayout rl2 = (relativelayout) findviewbyid(r.id.mainlayoutid);     imageview coin2 = new imageview(this);      relativelayout.layoutparams params2 = new relativelayout.layoutparams(30, 40);     params2.leftmargin = 50;      coin2 = (imageview) findviewbyid(r.id.coin2id);      animation coinfall1 = animationutils.loadanimation(this,             r.anim.coinanimation);     coin2.startanimation(coinfall1);      rl2.addview(coin2, params2); } 

logcat says line "rl.addview(coin1, params);" causes error.does know can fix this? there similar questions, new coding don't know how adapt answers problem.

any appreciated.

problem solved:

ashishduh solved problem replacing line:

rl.addview(coin1, params);   

with line:

coin1.setlayoutparams(params);   

hope helps someone! ashi <3

the view coin1 has parent (the relativelayout inflated). can't assign parent without removing relativelayout.

i think you're trying modify layoutparams of coin1. instead of doing this: rl.addview(coin1, params); need set layoutparams coin1.setlayoutparams(params);
