来源：互联网发布：淘宝优惠券推广图片编辑：程序博客网时间：2024/05/29 12:20

1. 游戏中常用的词：

金币，钱：Cash、PremiumCurrency、Gold, money

无CD: Cooldown

2. Git pull 强制覆盖本地文件
git fetch --all
git reset --hard origin/master
git pull

3. dump: Il2cppReflection::dumpClassFromObj((Il2CppObject*)attribute);

4.在lua中..是字符串连接操作符

5.装包：arg1[2] =mono_string_new_wrapper(cmd.data);

6. Android根据图片文件名获取它的资源ID 的两种方式 :
方式1：
public int getResource(String imageName){
Context ctx=getBaseContext();
int resId = getResources().getIdentifier(imageName, "drawable" , ctx.getPackageName());
return resId;
}

方式2：
public int getResourceByReflect(String imageName){
Class drawable = R.drawable.class;
Field field = null;
int r_id ;
try {
field = drawable.getField(imageName);
r_id = field.getInt(field.getName());
} catch (Exception e) {
r_id=R.drawable.b_nothing;
Log.e("ERROR", "PICTURE NOT　FOUND！");
}
return r_id;
}

checkbox事件：

viewHolder.cb.setOnClickListener(new CompoundButton.OnClickListener() {
@Override
public void onClick(View v) {
if (commodityInfo.isOwned()) {
boolean flag = commodityInfo.isOpen();
if (flag == true) {
viewHolder.cb.setChecked(true);
NativeUtils.nativeProcessCheat(commodityInfo.getNativeId(), 0, 1);
commodityInfo.setOpen(false);
}else{
viewHolder.cb.setChecked(false);
NativeUtils.nativeProcessCheat(commodityInfo.getNativeId(), 0, 0);
commodityInfo.setOpen(true);
}
} else {
viewHolder.cb.setChecked(false);
commodityInfo.setOpen(false);
GoodsManager.Buy(commodityInfo.getCommodityId());
}
}
});
