error:  <identifier> expected

我遇到的主要问题是R.java是由机器人工作室产生的，我从来没有碰过它让我很困惑。

The main problem I am having is that R.java is generated by android studio and I have never touched it so I am very confused.

实际R.java code是在这里。

The actual R.java code is here.

 public static final class id {
    public static final int =action_settings=0x7f050018;
    public static final int action_error=0x7f05000b;
    public static final int action_search=0x7f050017;
    public static final int action_settings=0x7f050016;
    public static final int action_success=0x7f05000d;
    public static final int all=0x7f050004;
    public static final int animation=0x7f05000e;
    public static final int bottom=0x7f050003;
    public static final int button_send=0x7f050014;
    public static final int dismiss_overlay_button=0x7f050011;
    public static final int dismiss_overlay_explain=0x7f050010;
    public static final int edit_message=0x7f050013;
    public static final int error_message=0x7f05000c;
    public static final int hybrid=0x7f050009;
    public static final int left=0x7f050000;
    public static final int message=0x7f05000f;
    public static final int none=0x7f050005;
    public static final int normal=0x7f050006;
    public static final int right=0x7f050002;
    public static final int satellite=0x7f050007;
    public static final int terrain=0x7f050008;
    public static final int text=0x7f050012;
    public static final int title=0x7f050015;
    public static final int top=0x7f050001;
    public static final int watch_view_stub=0x7f05000a;
}

该错误是扔在功能于= action_settings部分的第一行。

The error is thrown on the first line of the function at the =action_settings part.

任何帮助都将大大AP preciated。此外，如果有其他任何你需要看到，请让我知道。我仍然得到使用到Android和Android的工作室，所以我现在还不能确定这里的一切是为了帮助调试。

Any help at all would be greatly appreciated. Also if there is anything else you need to see please let me know. I'm still getting used to android and android studio so I am still not sure where everything is to help debug.

推荐答案

这听起来像你不小心用 = action_setting 的ID定义在XML的菜单项。

It sounds like you have accidentally defined a menu item in your XML with an id of =action_setting.

例如：

<menu>
    <item 
        android:id="@+id/=action_settings" />
</menu>

删除 = 从你的菜单XML，你应该是好去。

Remove the = from your menu XML and you should be good to go.
