我正在尝试添加actionbar演示。我为此使用了紧凑的v7应用程序，我需要在7到18个api级别上对此进行支持。我尝试了很多解决方案，但我无法获得适合我演示的合适解决方案。
问题是溢出菜单在Api级别的底部显示在 13。我需要在Top vesrion中显示所有内容。
此图像是API级别2.3。这是我所需要的完美。但是当我尝试在api级别
此图像是API级别4.0

最佳答案
这将迫使溢出按钮在所有设备上显示，主要问题是，如果有可用的硬件按钮，则不会显示溢出按钮。
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
}
但是使用此代码无论如何都应显示。
关于java - 使用V7 App Compat，Actionbar Overflow菜单没有显示在<13 API级别的顶部和orid中吗？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/20212054/
