What do I have to add to a layout to hide the titlebar?

I want to hide the titlebar of my app in some of my views. What do I have to add to the layout开发者_如何学Python files I want to hide the titlebar in? Can you provide an example?

Do you mean you want the screen going from something similar to this to something similar to that?

If that's what you want, make your theme inherit Theme.NoTitleBar or use it directly. Your opening Activity tag in the AndroidManifest.xml should look somethig like:

<activity android:name=".MyActivity"
    android:theme="@android:style/Theme.NoTitleBar">

If you only want to hide the title, but keep the title bar, you can go with Sephy's recommendations.

To do it in code you can just add this line of code to the onCreate() method.

requestWindowFeature(Window.FEATURE_NO_TITLE);

As specified here in accepted answer :

How to hide the title bar for an Activity in XML with existing custom theme

You could use it

<style name="nameOfYourTheme" parent="yourParentTheme">
     <item name="android:windowNoTitle">true</item>
</style>

If you mean the title in the grey bar just below the notification bar, you have to fill the "label" property of the activities you want not to display the application title in your manifest. You can then either define a title for the current activity of simply give an empty string. does it help?

<activity android:name="FirstActivity" android:label="it's title different from application's one"></activity>

Whenever I do the suggested changes, and then run rake run:android, each time my AndroidManifest file gets modified to its previous state.

I got the solution as,

Update your build.yml file as

android
  android_title: 0

This worked for me.
