推荐答案
我和横向模式同样的问题，我发现这里的解决方案： http://andreimihu.com/blog/一十分之二千零十三/ 17 / Android的始终嵌入-选项卡功能于动作条/
I had same issues with landscape mode and I found the solution here:http://andreimihu.com/blog/2013/10/17/android-always-embed-tabs-in-actionbar/
基本上，笔者希望内部动作条的标签，而我和你外面想要它。所以，只要方法调用更改为false（code从上面的链接，但有些修改）：
Basically, the writer wants the tab inside actionbar while you and I wants it outside. So, just change the method call to false (code from the above link, but a bit modified):
// This is where the magic happens!
public void forceTabs() {
try {
final ActionBar actionBar = getActionBar();
final Method setHasEmbeddedTabsMethod = actionBar.getClass()
.getDeclaredMethod("setHasEmbeddedTabs", boolean.class);
setHasEmbeddedTabsMethod.setAccessible(true);
setHasEmbeddedTabsMethod.invoke(actionBar, false);
}
catch(final Exception e) {
// Handle issues as needed: log, warn user, fallback etc
// This error is safe to ignore, standard tabs will appear.
}
}
