问题描述

每次我的 Optionsmenu 打开(onCreateOptionsMenu(..) 被调用)，我收到以下警告:

Each time my Optionsmenu opens (onCreateOptionsMenu(..) is called), I get these warnings:

id 0 没有键盘"

和

"使用默认键映射:/system/usr/keychars/qwerty.kcm.bin"

"Using default keyMap: /system/usr/keychars/qwerty.kcm.bin"

我不明白他们的意思，有人知道吗?我不喜欢 this answer.

I couldn't find out what they mean, does anyone know ? I didn't like this answer.

这是我正在使用的简单代码:

Here's the simple code I'm using:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    super.onCreateOptionsMenu(menu);
    getMenuInflater().inflate(R.menu.optmenu_start, menu);
    return true;
}

和 optmenu_start.xml:

and the optmenu_start.xml:

<menu xmlns:android="http://schemas.android.com/apk/res/android">
  <item
    android:id="@+id/optmenu_prefs"
    android:title="@string/optmenu_prefs"
    android:icon="@drawable/icon_menu_prefs"
  />
  <item
    android:id="@+id/optmenu_help"
    android:title="@string/optmenu_help"
    android:icon="@drawable/icon_menu_help"
  />
</menu>

推荐答案

谷歌的答案是

" 日志是正常的；它发生在设备第一次需要键盘映射时在一个过程中."

" The log is normal; it happens the first time a keymap is needed for a device in a process. "

因此，如果您在 Activity1 之前启动 Activity2，您会在 Activity2 而不是 Activity1 中看到警告！

So therefore if you started Activity2 before Activity1 you would see the warning in Activity2 and not Activity1!

正如我所说，我认为很多开发人员都会收到此消息，这只是警告而不是错误；可以忽略.

As I said I think a lot of developers get this message and it's just a warning not an error; it can be ignored.
