我已经搜索了很多，以使精灵（_player）被检测到并与另一个精灵（目标）发生碰撞，并在通过谷歌和stackoverflow站点发生碰撞后被删除，但在cocos2d-android中找不到解决方案，我是能够在 cocos2d-iphone 上找到很多信息，而不是在 android 上，即使我已经将我的代码与 iphone 代码进行了比较，但无法弄清楚。这就是我所做的。

public class GameLayer extends CCColorLayer
 {
protected LinkedList<CCSprite> _targets;
protected LinkedList<CCSprite> _projectiles;
protected int _projectilesDestroyed;
protected CCSprite _player;
protected CCSprite _nextProjectile;

public static CCScene scene()
{
    CCScene scene = CCScene.node();
    CCColorLayer layer = new GameLayer(ccColor4B.ccc4(255, 255, 255, 255));

    scene.addChild(layer);

    return scene;
}


protected GameLayer(ccColor4B color)
{
    super(color);

    this.setIsTouchEnabled(true);

    _targets = new LinkedList<CCSprite>();
    _projectiles = new LinkedList<CCSprite>();
    _projectilesDestroyed = 0;

    CGSize winSize = CCDirector.sharedDirector().displaySize();

    _player = CCSprite.sprite("Player2.png");
    _player.setPosition(CGPoint.ccp(_player.getContentSize().width / 2.0f, winSize.height / 2.0f));

    addChild(_player);


    this.schedule("gameLogic", 1.0f);
    this.schedule("update");
}

更新方法

public void update(float dt)
{
    LinkedList<CCSprite> projectilesToDelete = new LinkedList<CCSprite>();

    for (CCSprite projectile : _projectiles)
    {
        CGRect projectileRect = CGRect.make(projectile.getPosition().x - (projectile.getContentSize().width / 2.0f),
                                            projectile.getPosition().y - (projectile.getContentSize().height / 2.0f),
                                            projectile.getContentSize().width,
                                            projectile.getContentSize().height);

        LinkedList<CCSprite> targetsToDelete = new LinkedList<CCSprite>();

        for (CCSprite target : _targets)
        {
            CGRect targetRect = CGRect.make(target.getPosition().x - (target.getContentSize().width),
                                            target.getPosition().y - (target.getContentSize().height),
                                            target.getContentSize().width,
                                            target.getContentSize().height);



            _player = CCSprite.sprite("Player2.png");
            _player.setPosition(CGPoint.ccp(50,100));
            CGRect playerRect = CGRect.make(_player.getPosition().x - (_player.getContentSize().width / 2.0f),
                    _player.getPosition().y - (_player.getContentSize().height / 2.0f),
                    _player.getContentSize().width,
                    _player.getContentSize().height);

            if (CGRect.intersects(projectileRect, targetRect))
                targetsToDelete.add(target);


            else if (CGRect.intersects(playerRect, targetRect))
                _player.remove(_player);
            removeChild(_player, true);

        }

        for (CCSprite target : targetsToDelete)
        {
            _targets.remove(target);
            removeChild(target, true);
        }

        if (targetsToDelete.size() > 0)
            projectilesToDelete.add(projectile);
    }

为了找出这个答案的解决方案，花了一周的时间：（当一个新的精灵首先添加到游戏中时，它应该在 addsomefunction() 方法中声明，我的错误是我在构造函数中声明了 ship(sprite) 的值，而不是addTarget() 并在碰撞后删除精灵，代码必须public void spriteMoveFinished(Object sender)以

if (sprite.getTag() == 25)
_ships.remove(sprite);

因为我在这个方法中有 Target(sprite)，所以很困惑，比如在哪里添加代码。
