java - Actionbar Overflow 菜单未显示在 < 13 API 级别和/或使用 V7 App Compat 的顶部？

Question

我正在尝试创建操作栏演示。我为此使用了 v7 app compact，我需要在 7 到 18 api 级别上支持它。我尝试了很多解决方案，但无法找到适合我的演示的合适解决方案。 问题是 Api 级别 < 13 和 > 13 显示在底部的溢出菜单显示在顶部。我需要在 Top all vesrion 中显示。

这张图片是 API 级别 2.3。这正是我所需要的。但是当我尝试在 api 级别 < 13 上进行测试时

这张图片是 API 级别 4.0

Answer 1

这将强制溢出按钮在所有设备上显示，主要问题是溢出按钮在硬件按钮可用时不显示。

    try {
        ViewConfiguration config = ViewConfiguration.get(this);
        Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey");
        if(menuKeyField != null) {
            menuKeyField.setAccessible(true);
            menuKeyField.setBoolean(config, false);
        }
    } catch (Exception ex) {
        // Ignore
    }

但是有了这段代码，无论如何它都应该显示。
