有2张PNG图标问题不大
我的问题是我点击模拟器中的menu时，缺调不出来选项菜单。程序没错误 但找不到到底问题在什么地方。 不好意思 代码没有注释，高手都能看懂这么简单的代码。送分！

[解决办法]
public boolean onCeateOptionsMenu(Menu menu){

public boolean onCreateOptionsMenu(Menu menu){
你觉得有差别吗？
[解决办法]
public boolean onCeateOptionsMenu//书写错误(Menu menu){

SubMenu subMenuGender = menu.addSubMenu(MAIN_GROUP,MENU_GENDER,0,R.string.gender);
subMenuGender.setIcon(R.drawable.gender);
