每当使用switch语句调用此方法时，我都会遇到两个问题：
有时（是的，只是有时，不是每次）当变量 mDNumHit 值为1时，运行的是案例2或案例3，而不是案例1。
什么时候 mDNumhit 是1，它运行案例1。现在，假设 dCards3 是9，案例9已经运行，但只有这部分代码
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
mImgDCard3.setImageResource(R.drawable.clubs9);
}
}, 500);是运行的，这个
dTotal += 9;
dTotalAlt += 9;没有（变量没有更新）。
为什么会这样？我只是不知道怎么了。
代码：
public boolean dealerHit() {
final AnimationSet as = new AnimationSet(true);
as.addAnimation(animTranslate);
as.addAnimation(animSet);
final Random r = new Random();
//dealer hit
while ((dTotal < 17) && (dTotalAlt < 17) && ((mDNumHit + 2) < mMaxCards)) {
//update num of hit by dealer
mDNumHit++;
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
cardSound.start();
switch (mDNumHit) {
case 1:
//create a random card

mImgDCard3.setVisibility(View.VISIBLE);
mImgDCard3.startAnimation(as);

按热度按时间knpiaxh11#
mDNumHit是一个字段，但是，您正在创建一个具有runnable的处理程序—它强烈建议多个线程。所以，发生的事情是，一个线程在切换之前改变了mdnumhit。修复方法是不为此使用字段，而是将mdnumhit的值传递给处理程序。
这有点像有一个全球性的白板，每次有一个新的销售，有人跑上来，抹去数字，并写下下下一个数字。
想象一下，那些将订单打包到一个盒子里的人，每次都要查看白板，然后再查看订单。如果有人在 Package 过程中更改了号码，这将是完全错误的。
解决办法是告诉他们根本不要看白板——把需要打包的订单号递给他们，告诉他们只看那个。
