从导航抽屉ActionBar中删除应用程序图标不起作用 [英] Remove App Icon from Navigation Drawer ActionBar Does not work

问题描述

我正在开发一个具有设计要求的应用程序，因为该应用程序仅在ActionBar上具有标题，而在App Icon上则没有. 我尝试了从StackOverflow找到的各种解决方案，例如

I am working on an App which has design requirement to be built as it should only have the Title on the ActionBar and not the App Icon. i tried various solutions found from StackOverflow like

getActionBar().setDisplayUseLogoEnabled(false);

    getActionBar().setDisplayShowHomeEnabled(false);

    getActionBar().setIcon(null);

但是到目前为止，这些方法都无效，甚至我都尝试通过制作透明的ic_launcher图标并将其放入manifest.xml来进行破解/修复，但这会导致App安装图标透明. 请帮助

however none of these worked so far, even i tried to make a hack/fix by making a transparent ic_launcher icon and put it into manifest.xml but it causes the App installation icon make transparent. please help

getActionBar().setDisplayShowHomeEnabled(false);

在4.4 kitkat中可以完美工作，但是在降级版本中显示像这样的后退箭头

works perfectly in 4.4 kitkat , but showing a back arrow in downgraded version like this

我需要这样才能在每台设备上正常工作

and i need it like this to work in every device

推荐答案

无论如何它都非常棘手，但是我解决了它，它在所有设备中都像魅力一样.

Its quite tricky anyhow, but i solved it,and it works like a charm in all devices.

我制作了一个2x2 px的透明图标，并将其添加为

I made a 2x2 px transparant icon and added it as

ActionBar actionBar = getActionBar();
actionBar.setIcon(R.drawable.actionbar_null_icon);

并删除了代码

getActionBar().setDisplayUseLogoEnabled(false);
getActionBar().setDisplayShowHomeEnabled(false);
