How to hide the title bar for an Activity in XML with existing custom theme
提问by Janusz
I want to hide the titlebar for some of my activities. The problem is that I applied a style to all my activities, therefore I can't simply set the theme to @android:style/Theme.NoTitleBar.
我想隐藏我的一些活动的标题栏。问题是我对所有活动应用了一种样式，因此我不能简单地将主题设置为@android:style/Theme.NoTitleBar.
Using the NoTitleBartheme as a parent for my style would remove the title bar from all of my activities.
使用NoTitleBar主题作为我的样式的父主题会从我的所有活动中删除标题栏。
Can I set a no title style item somewhere?
我可以在某处设置无标题样式项吗？

I now did the following.
我现在做了以下事情。
I declared a style inheriting everything from my general style and then disabling the titleBar.
我声明了一种样式，它继承了我的一般样式的所有内容，然后禁用了 titleBar。
<style name="generalnotitle" parent="general">
<item name="android:windowNoTitle">true</item>
</style>
Now I can set this style to every Activity in which I want to hide the title bar overwriting the application wide style and inheriting all the other style informations, therefor no duplication in the style code.
现在我可以将此样式设置为每个我想要隐藏标题栏的活动，覆盖应用程序范围的样式并继承所有其他样式信息，因此样式代码中没有重复。
To apply the style to a particular Activity, open AndroidManifest.xmland add the following attribute to the activitytag;
要将样式应用于特定活动，请打开AndroidManifest.xml并将以下属性添加到activity标签；
<activity
android:theme="@style/generalnotitle">

Do this in your onCreate()method.
在您的onCreate()方法中执行此操作。
//Remove title bar
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
//Remove notification bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
//set content view AFTER ABOVE sequence (to avoid crash)
this.setContentView(R.layout.your_layout_name_here);
thisrefers to the Activity.
this指的是Activity.

You can modify your AndroidManifest.xml:
您可以修改您的AndroidManifest.xml：
<activity android:name=".MainActivity"
android:label="@string/app_name"
android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">
or use android:theme="@android:style/Theme.Black.NoTitleBar"if you don't need a fullscreen Activity.
或者android:theme="@android:style/Theme.Black.NoTitleBar"在不需要全屏活动时使用。
Note:If you've used a 'default' view before, you probably should also change the parent class from AppCompatActivityto Activity.
注意：如果您之前使用过“默认”视图，您可能还应该将父类从 更改AppCompatActivity为Activity。

I don't like the this.requestWindowFeature(Window.FEATURE_NO_TITLE);because the title bar appears briefly, then disappears.
我不喜欢 ，this.requestWindowFeature(Window.FEATURE_NO_TITLE);因为标题栏短暂出现，然后消失。
I also don't like the android:theme="@android:style/Theme.NoTitleBar"because I lost all of the 3.0+ Holo changes that the users of the new devices have gotten used to. So I came across this solution.
我也不喜欢 ，android:theme="@android:style/Theme.NoTitleBar"因为我丢失了新设备用户已经习惯的所有 3.0+ Holo 更改。所以我遇到了这个解决方案。
In your res/valuesfolder make a file called styles.xml(If it doesn't already exist). In that file place the following code:
在res/values文件夹中创建一个名为styles.xml的文件（如果它不存在）。在该文件中放置以下代码：
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="Theme.Default" parent="@android:style/Theme"></style>
<style name="Theme.NoTitle" parent="@android:style/Theme.NoTitleBar"></style>
<style name="Theme.FullScreen" parent="@android:style/Theme.NoTitleBar.Fullscreen"></style>
</resources>
Next create a res/values-v11with another styles.xmlfile (Once again this may already exist). In that file place the following code:
接下来创建一个res/values-v11和另一个style.xml文件（这可能已经存在）。在该文件中放置以下代码：
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="Theme.Default" parent="@android:style/Theme.Holo"></style>
<style name="Theme.NoTitle" parent="@android:style/Theme.Holo.NoActionBar"></style>
<style name="Theme.FullScreen" parent="@android:style/Theme.Holo.NoActionBar.Fullscreen"></style>
</resources>
And if you are targeting 4.0+, create a res/values-v14folder with yet another styles.xmlfile (Yes it may already be there). In that file place the following code:
如果您的目标是 4.0+，请使用另一个styles.xml文件创建res/values-v14文件夹（是的，它可能已经存在）。在该文件中放置以下代码：
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="Theme.Default" parent="@android:style/Theme.Holo.Light"></style>
<style name="Theme.NoTitle" parent="@android:style/Theme.Holo.Light.NoActionBar"></style>
<style name="Theme.FullScreen" parent="@android:style/Theme.Holo.Light.NoActionBar.Fullscreen"></style>
</resources>
Finally, with all of these files created, open your AndroidManifiest.xmlfile you can add the code:
最后，创建所有这些文件后，打开您的AndroidManifyingt.xml文件，您可以添加以下代码：
android:theme="@style/Theme.NoTitle"
to the activity tag of the activity you want no title for or the application tag if you want it to apply to the entire application.
如果您希望将其应用于整个应用程序，则添加到您不想要标题的活动的活动标签或应用程序标签。
Now your users will get the themes associated with their device version with the screen layout you desire.
现在，您的用户将获得与其设备版本相关的主题以及您想要的屏幕布局。
P.S. Changing the value to android:theme="@style/Theme.FullScreen"will have the same effect, but also remove Notification bar.
PS 将值更改为android:theme="@style/Theme.FullScreen"将具有相同的效果，但也会删除通知栏。

The title bar can be removed in two ways as mentioned on the developer Android page:
可以通过开发者 Android 页面上提到的两种方式删除标题栏：
In the manifest.xmlfile:
在manifest.xml文件中：
Add the following in
applicationif you want to remove it for all the activities in an app:<application android:theme="@android:style/Theme.Black.NoTitleBar">Or for a particular activity:
<activity android:theme="@android:style/Theme.Black.NoTitleBar">
application如果要为应用程序中的所有活动删除它，请添加以下内容：<application android:theme="@android:style/Theme.Black.NoTitleBar">或针对特定活动：
<activity android:theme="@android:style/Theme.Black.NoTitleBar">
回答by Shimon Doodkin
the correct answer probably is to not extend ActionbarActivity rather extend just Activity
正确的答案可能是不扩展 ActionbarActivity 而只扩展 Activity
if you still use actionbar activity seems this is working:
如果您仍然使用操作栏活动，这似乎有效：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportActionBar().hide(); //<< this
setContentView(R.layout.activity_main);
}
seems this works too:
似乎这也有效：
styles.xml:
<style name="AppBaseTheme" parent="Theme.AppCompat.Light" >
<item name="android:windowNoTitle">true</item> <!-- //this -->
</style>
i could do like as Scott Biggs wrote. this kind of works. except there is no theme then. i mean the settings menu's background is transparent:
我可以像 Scott Biggs 写的那样做。这种作品。除了那时没有主题。我的意思是设置菜单的背景是透明的：
just change
只是改变
public class MainActivity extends ActionBarActivity {
to Activity or FragmentActivity
到 Activity 或 FragmentActivity
public class MainActivity extends Activity {
however i could make it look good enough using material design and not remove the actionbar: https://gist.github.com/shimondoodkin/86e56b3351b704a05e53
但是我可以使用材料设计让它看起来足够好，而不是删除操作栏：https://gist.github.com/shimondoodkin/86e56b3351b704a05e53
- set icon of application
- set colors of action bar to match design.
- set icon to settings menu
- add more icons (buttons on top)
- 设置应用程序图标
- 设置操作栏的颜色以匹配设计。
- 将图标设置为设置菜单
- 添加更多图标（顶部的按钮）
it is by example of material design compatibility actionbar styling.
它以材料设计兼容性操作栏样式为例。

what works for me:
什么对我有用：
1- in styles.xml:
1-在styles.xml中：
<style name="generalnotitle" parent="Theme.AppCompat.Light" >
<item name="android:windowNoTitle">true</item> <!-- //this -->
</style>
2- in MainActivity
2- 在 MainActivity
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportActionBar().hide(); //<< this
setContentView(R.layout.activity_main);
}
in manifest inherit the style:
<activity android:name=".MainActivity" android:theme="@style/generalnotitle">
在清单中继承样式：
<activity android:name=".MainActivity" android:theme="@style/generalnotitle">
回答by raj c
If you use this.requestWindowFeature(Window.FEATURE_NO_TITLE)user will still be able to see the title bar just for a moment during launch animation when activity starts through onCreate. If you use @android:style/Theme.Black.NoTitleBaras shown below then title bar won't be shown during launch animation.
如果您使用，this.requestWindowFeature(Window.FEATURE_NO_TITLE)当活动开始时，用户仍然可以在启动动画期间看到标题栏片刻onCreate。如果您使用@android:style/Theme.Black.NoTitleBar如下所示，则在启动动画期间将不会显示标题栏。
<activity
android:name=".MainActivity"
android:label="My App"
android:theme="@android:style/Theme.Black.NoTitleBar"
android:screenOrientation="portrait">
above example will obviously override your existing application theme, if you have existing theme then add <item name="android:windowNoTitle">true</item>to it.
上面的例子显然会覆盖你现有的应用程序主题，如果你有现有的主题然后添加<item name="android:windowNoTitle">true</item>到它。
回答by TryToSolveItSimple
when i tried to use all those high upvoted answers my app always crashed. (i think it has something to do with the "@android:style"?)
当我尝试使用所有这些高票答案时，我的应用程序总是崩溃。（我认为这与“@android:style”有关？）
The best solution for me was to use the following:
对我来说最好的解决方案是使用以下内容：
android:theme="@style/Theme.AppCompat.NoActionBar"
No header / title bar anymore. Just place it in the <application>...</application>or <activity>...</activity>depending if you (don't) want it in the whole app or just a specific activity.
没有标题/标题栏了。只需将它放在<application>...</application>或<activity>...</activity>取决于您（不）想要它在整个应用程序中还是只是一个特定的活动。

Create a theme as below.
创建一个主题如下。
<!-- Variation on the Light theme that turns off the title -->
<style name="MyTheme" parent="android:style/Theme.Black">
<item name="android:windowNoTitle">true</item>
</style>
