blocks|key|855014|text|如果您的应用程序主题是AppTheme(或其他任何主题)，那么在styles.xml中添加以下代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|855015|<style+name="HiddenTitleTheme"+parent="AppTheme">

++++<item+name="windowActionBar">false</item>

If your application theme is AppTheme(or anything else), then in styles.xml add the following code: 

<pre><code>&lt;style name="HiddenTitleTheme" parent="AppTheme"&gt;
 &lt;item name="windowNoTitle"&gt;true&lt;/item&gt;
 &lt;item name="windowActionBar"&gt;false&lt;/item&gt;
 &lt;/style&gt;
</code></pre>

Then in manifest file add the following in the activity tag for which you want to disable activity label:

<pre><code>android:theme="@style/HiddenTitleTheme"
</code></pre>

blocks|key|854810|text|我不能100%25确定这是你想要的，但如果你指的是标题栏(顶部的小灰色条)，你可以通过你的manifest.xml文件删除/定制它……|type|unstyled|depth|inlineStyleRanges|entityRanges|data|854811|<activity+android:name=".activities.Main"

I am not 100% sure this is what you want but if you are referring to the title bar (the little gray strip at the top), you can remove/customize it via your manifest.xml file...

<pre><code>&lt;activity android:name=".activities.Main"
 android:theme="@android:style/Theme.NoTitleBar"&gt;
</code></pre>

blocks|key|1069640|text|你可以试试这个|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1069641|+ActionBar+actionBar+=+getSupportActionBar();

you can try this

<pre><code> ActionBar actionBar = getSupportActionBar();
 actionBar.setDisplayShowTitleEnabled(false);
</code></pre>

blocks|key|1069273|text|有一个代码here可以做到这一点。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1069274|诀窍就在这一行：|1069275|+title.setVisibility(View.GONE);|code-block|syntax|javascript|1069276|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/4289439/android-custom-titlebar-hide-text/4289633#4289633^0|5|4|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@$A|T|B|U|1|V]]|C|$]]|$1|D|3|E|5|6|7|W|8|@]|9|@]|C|$]]|$1|F|3|G|5|H|7|X|8|@]|9|@]|C|$I|J]]|$1|K|3|-4|5|6|7|Y|8|@]|9|@]|C|$]]]|L|$M|$5|N|O|P|C|$Q|R]]]]

There is a code <a href="https://stackoverflow.com/questions/4289439/android-custom-titlebar-hide-text/4289633#4289633">here</a> that does it.

The trick is at this line:

<pre><code> title.setVisibility(View.GONE);
</code></pre>

blocks|key|854930|text|在eclipse的图形布局窗口中也有一个下拉菜单。此菜单中的一些主题将在末尾显示".NoTitleBar“。其中任何一个都能起作用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|854931|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

There's also a drop down menu in the graphical layout window of eclipse. some of the themes in this menu will have ".NoTitleBar" at the end. any of these will do trick.

blocks|key|1069508|text|在我的情况下，其他答案是不够的.|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1069509|<style+name="AppTheme"+parent="Theme.AppCompat.Light.DarkActionBar">

blocks|key|855119|text|您可以在AndroidManifest.xml的活动标记中使用它来隐藏标签|type|unstyled|depth|inlineStyleRanges|entityRanges|data|855120|android:label=""|code-block|syntax|javascript|855121|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

you can use this in your activity tag in AndroidManifest.xml to hide label

<pre><code>android:label=""
</code></pre>

blocks|key|1069633|text|如果你使用的是Android+Studio+3%2B，这将会起作用:+android:theme="@style/Theme.AppCompat.NoActionBar“|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1069634|@android:style/Theme.NoTitleBar在新的API中不支持，会强制关闭你的应用。|1069635|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

IF you are using Android Studio 3+ This will work: android:theme="@style/Theme.AppCompat.NoActionBar" 

@android:style/Theme.NoTitleBar will not support in new API and force you app close.

blocks|key|1069574|text|有了工具栏，你就可以解决这个问题。使用setTitle方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1069575|+Toolbar+++mToolbar+=+(Toolbar)+findViewById(R.id.toolbar);
++mToolbar.setTitle("");
++setSupportActionBar(mToolbar);|code-block|syntax|javascript|1069576|超级简单:)|1069577|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

with your toolbar you can solve that problem. use setTitle method.

<pre><code> Toolbar mToolbar = (Toolbar) findViewById(R.id.toolbar);
 mToolbar.setTitle("");
 setSupportActionBar(mToolbar);
</code></pre>

super easy :)

Is there anyway to remove activity label bar and label itself which is set by default from application label? 
I'd like to have whole layout from my design and need to remove the label bar and label which is in TOP layout.

How disable / remove android activity label and label bar?

有没有办法从应用程序标签中删除默认设置的活动标签栏和标签本身？我想从我的设计整个布局，并需要删除标签栏和标签，这是在顶部布局。
