Android 菜单项标题未显示 [英] Android Menu Item Title not displaying

问题描述

我一直在摆弄 android，我一直在关注菜单示例，它运行得几乎正常，但是菜单项的标题"字段没有显示.

I've been fiddling with android, and I've been following the menu sample, and it runs almost fine, but the "title" field of the menu items isn't displaying.

我认为这与这个问题有关:https://stackoverflow.com/questions/3286093/android-menu-item-not-显示文本但我不确定他的回答是什么意思.

I think it's related to this question: https://stackoverflow.com/questions/3286093/android-menu-item-not-showing-text but I'm not sure what his answer means.

无论如何，它正确地知道我有 2 个菜单项，只是没有显示文本.我不太确定错误在哪里，并认为多一些眼睛会很好.

Anyway, it properly gets that I have 2 menu items, it just isn't displaying the text. I'm not quite sure where the error is and figured extra sets of eyes would be good.

XML:

<?xml version="1.0" encoding="UTF-8"?>
<menu xmlns:android="https://schemas.android.com/apk/res/android">
 <item android:id="@+id/options"
  android:title="@string/main_options" />
 <item android:id="@+id/options2"
  android:title="@string/main_options2" />
</menu>

充气机:

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.main_menu, menu);
        return true;
    }

如果还有什么需要，请告诉我.

If anything else is needed, let me know.

字符串文件:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="hello">Hello World!</string>
    <string name="app_name">LifeInColor</string>
 <string name="main_options">Options</string>
 <string name="main_options2">Something goes here</string>
</resources>

将xml更改为:

 <?xml version="1.0" encoding="UTF-8"?>
    <menu xmlns:android="https://schemas.android.com/apk/res/android">
     <item android:id="@+id/options"
      android:title="@string/main_options" />
     <item android:id="@+id/options2"
      android:title="Something goes here" />
    </menu>

得到相同的结果.我有一张照片，但它不允许我发布，因为我是新人.

gets the same result. I have a picture, but it won't let me post it because I'm new.

推荐答案

在您的菜单文件中，将 https://schemas.android.com/apk/res/android 替换为 http://schemas.android.com/apk/res/android (https -> http).所以看起来这个错误是由于不正确的架构地址造成的.

In your menu file replace https://schemas.android.com/apk/res/android with http://schemas.android.com/apk/res/android (https -> http). So it looks like the error was due to incorrect schema address.
