Android: Hide ActionBar, keep Tabs
提问by josephoneill
To keep this simple: I have tabs in my actionbar, but the action bar take up too much space. I want that extra space. I need a way to hide the action bar, yet keep my tabs. Is there anyway to do this? Or is there a way I can get the tabs built into the action bar like it is in landscape mode? Thanks!
为了简单起见：我的操作栏中有选项卡，但操作栏占用了太多空间。我想要那个额外的空间。我需要一种方法来隐藏操作栏，同时保留我的标签。有没有办法做到这一点？或者有没有办法像在横向模式下一样将选项卡内置到操作栏中？谢谢！

You can have an empty Actionbar, then the tabs will occupy the space:
您可以有一个空的 Actionbar，然后选项卡将占据空间：
getSupportActionBar().setDisplayShowHomeEnabled(false);
getSupportActionBar().setDisplayShowTitleEnabled(false);

Try the below code:
试试下面的代码：
final ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayShowTitleEnabled(false);
Also remove the below in code which is added default when project is created:
还要删除以下代码，该代码在创建项目时默认添加：
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

This did the trick for me
这对我有用
actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
I also commented the line
我也评论了这一行
getMenuInflater().inflate(R.menu.main, menu);

Ahmad's answer is correct but it requires API 11. For supporting lower APIs, use this code -
Ahmad 的回答是正确的，但它需要 API 11。要支持较低的 API，请使用此代码 -
setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
To enable it, use -
要启用它，请使用 -
setNavigationMode(ActionBar.NAVIGATION_MODE_TABS)
