我正在开发一对卡片记忆匹配游戏 它包含一个4x4矩阵。
当我在任何按钮上单击两次时，它会消失 点击一些按钮后，不幸的是游戏停止并返回菜单屏幕。
相反，当卡片匹配并播放一些声音时，该过程应该使卡片对不可见。

答案 0 :(得分：0)
你真的必须在这里添加一个额外的条件：
private void doPlayMove() {
mc_counter++;
if((secondId != firstId) && (img_bird[firstid][1] - img_bird[secondid][1] == 0)) {
...
虽然你做得更好，但只有当它尚未被选中时才能“选择”一个元素。
if(mc_isfirst) {
// turning the first card
firstid = i;
// re enable all except this one
for(Button b : myBird) {
if(b.getId() != firstid) {
b.setEnabled(true);
}
}
} else {
// turning the second card
if(i != firstid) {
secondid = i;
doPlayMove();
}
}
你应该采用最后一种方法。
