我正在为最多四名玩家制作一个基本的纸牌游戏，我有一个问题，我无法解决。
我有几个布局堆叠在一起（match_parent）。
我已将图像视图添加到每个布局，并在将cardView传递给下一个方法之前为其添加了标记。
void animateCard(int finalX, int finalY, final ImageView cardView, final String playerId, final int n){
int duration = 180;
ObjectAnimator animX = ObjectAnimator.ofFloat(cardView, "x", finalX);
ObjectAnimator animY = ObjectAnimator.ofFloat(cardView, "y", finalY);
animX.setDuration(duration);
animY.setDuration(duration);
// animX.start();
AnimatorSet animSetXY = new AnimatorSet();
animSetXY.playTogether(animX, animY);
animSetXY.start();
animSetXY.addListener(new Animator.AnimatorListener() {
@Override
public void onAnimationStart(Animator animation) {
}
@Override
public void onAnimationEnd(Animator animation) {
float cardX = cardView.getX();
float cardY = cardView.getY();
if (playerId.equals("human")) {
}
else if (playerId.equals("topPlayer")){
Log.e("TopPlayerHAnd: ", String.valueOf(topPlayerHand));
Log.e("cardViewGetTag: ", String.valueOf(cardView.getTag()));
Log.e("parent: ", String.valueOf(cardView.getParent()));
Log.e("TPAL tag at 0: ", String.valueOf(topPlayerAreaLayout.getChildAt(0).getTag()));
}
}
@Override
public void onAnimationCancel(Animator animation) {
}
@Override
public void onAnimationRepeat(Animator animation) {
}
});
}
问题是尝试通过调用Log.e来获取标记（“TPAL tag at 0：”，String.valueOf（topPlayerAreaLayout.getChildAt（0）.getTag（）））;正在返回“null”。
然而，Log.e（“cardViewGetTag：”，String.valueOf（cardView.getTag（）））;
返回实际标记和
Log.e（“parent：”，String.valueOf（cardView.getParent（）））;
记录android.widget.RelativeLayout {7133a69 VE ..... ...... ID 0,0-1184,720＃7f0c0061 app：id / topPlayerAreaLayout}作为找到cardView的布局。< / p>
topPlayerAreaLayout.getChildCount（）;返回正确数量的子项，但没有标记！
我已经连续几天撞到了墙上，但没有结果。
编辑：这是我为视图设置标签的方法： edit2：如果playerId.equals（“human”）
，标签将完整无缺地通过animateCard方法 void addCardsToTopAndBottomHands(final String whichPlayer, final RelativeLayout thisLayout, final int initialCardX, final int initialCardY, ArrayList playerDeck, int totalCardsToAdd){
Log.e("addCardsLayout: ", String.valueOf(thisLayout));
int n = 0;
String cardTag = "";
while( n< totalCardsToAdd){
final int q = n;
int duration = 180 *(n+1);
int multiplier = 0;
final ImageView thisCardView = new ImageView(this);
playerDeck.add(thisDeck.get(0));
String cardTag = String.valueOf(thisDeck.get(0));
thisDeck.remove(0);
thisCardView.setTag(cardTag);
if (whichPlayer.equals("human")) {
multiplier =((playingCardWidth*(q+1))+9);
final int cardId = getResources().getIdentifier(String.valueOf(playerDeck.get(n)), "drawable", getPackageName());
thisCardView.setImageResource(cardId);
}
else {
thisCardView.setImageResource(R.drawable.cardback);
multiplier = halfCardWidth *(q+1);
Log.e("playerName: ", whichPlayer);
Log.e("playerDeck: ", String.valueOf(playerDeck));
}
final int cardXCoord = initialCardX + multiplier;
final int cardYCoord = initialCardY + multiplier;
CountDownTimer countDownTimer = new CountDownTimer(duration, duration) {
@Override
public void onTick(long millisUntilFinished) {
}
@Override
public void onFinish() {
thisLayout.addView(thisCardView);
Log.e("playerName: ", whichPlayer);
Log.e("counting in: ", String.valueOf(thisLayout.getChildCount()));
Log.e ("thisCardTag: ", String.valueOf(thisCardView.getTag()));
Log.e("thisLayout: ", String.valueOf(thisLayout));
Log.e("TPAL count: ", String.valueOf(topPlayerAreaLayout.getChildCount()));
String message = "Tag at " + String.valueOf(q);
Log.e(message, String.valueOf(topPlayerAreaLayout.getChildAt(q).getTag()));
//TODO: TPAL imageView tags are intact here! WTF did they go?
thisCardView.requestLayout();
thisCardView.setX(centreCardX);
thisCardView.setY(centreCardY);
thisCardView.getLayoutParams().height = playingCardHeight;
thisCardView.getLayoutParams().width = playingCardWidth;
// Log.e("this q: ", String.valueOf(q) );
if (whichPlayer.equals("human")|| whichPlayer.equals("topPlayer")) {
animateCard(cardXCoord, initialCardY, thisCardView, whichPlayer, q);
}
else if (whichPlayer.equals("leftPlayer")|| whichPlayer.equals("rightPlayer")){
animateCard(initialCardX, cardYCoord, thisCardView, whichPlayer, q );
}
}
}; countDownTimer.start();
n++;
}
}
