上面是我的MainActivity文件代码.我用自定义操作栏实现简单的NavigationDrawer.这就是为什么抽屉图标未在某些设备中显示的原因.如果我使用默认操作栏，那它就可以正常工作.
above is my MainActivity file code. i implementing simple navigationdrawer with custom actionbar. that's why drawer icon not showing in some devices. if i used default actionbar than it works fine.
下面是我的输出:
帮助我解决此错误.
推荐答案
我通过替换以下内容解决了我的问题:
I solved my problem by replacing:
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setDisplayUseLogoEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setHomeButtonEnabled(true);
actionBar.setIcon(null);
具有:
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM | ActionBar.DISPLAY_SHOW_HOME | ActionBar.DISPLAY_HOME_AS_UP);
actionBar.setIcon(android.R.color.transparent);
