【问题描述】：
在动画结束时删除视图时我面临异常。只有在播放动画的同时将应用程序置于前台时才会发生这种情况。下面是代码sn-p。任何帮助将不胜感激。
public void onAnimationEnd(Animation animation) {
new Handler().post(new Runnable() {
@Override
public void run() {
try{
setActivePlayer(nextPlayer, time);
String source = discardAnimationCard.getCardSource();
openCard.updateCardSource(source);
if(gameTable.indexOfChild(discardAnimationCard) >= 0){
gameTable.removeView(discardAnimationCard);
}
String discardAckMessage = "DiscA#";
String round = "1";
if( gameId.indexOf("-") >= 0 ){
round = gameId.split("-")[1];
}
discardAckMessage += gameCode+"@"+round+":"+source;
gameDataReader.gameHandler.sendMessage(discardAckMessage);
}catch(Exception e){
}
}
});
下面是堆栈跟踪

请点击edit并添加stacktrace作为LogCat的输出。我们无法调试我们看不到的东西。由于缺乏背景，投票结束。

以上堆栈跟踪取自 LogCat。
