您是否尝试过setTitleCondensed,我刚刚检查了文档,似乎标题太长且空间不足,首选方法是使用setTitleCondensed。
call ActivityCompat.invalidateOptionsMenu(this.getActivity)
to reload the onCreateOptionMenu for android version greater than 11 调用
ActivityCompat.invalidateOptionsMenu(this.getActivity)
以重新加载大于11的android版本的onCreateOptionMenu
MenuItem b = (MenuItem) findViewById(R.id.action_data);
b.setTitle(new SimpleDateFormat("dd-MM-yy").format(c));
ActivityCompat.invalidateOptionsMenu(this.getActivity)
