Hide or remove Action Bar on specific Activity | A

问题:

How I can remove Action Bar on specific activity not for all application, for example I have Sign Up activity and for this activity I want to remove Action Bar

回答1:

In your AndroidManifest.xml use NoActionBar theme for your Activity like this:

<activity android:name=".SignUpActivity"
          android:theme="@style/AppTheme.NoActionBar"/>

and in your styles.xml

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

回答2:

from within your activity:

getActionBar().hide();

or

getSupportActionBar().hide();

I would suggest to migrate to ToolBar, new Android API for the same purpose. The main benefit of ToolBar is that you can treat it like other views, it guarantees to you a more flexible approach.

回答3:

If you have an ActionBar, you can use getActionBar().hide();
If you have a SupportActionBar, you can use getSupportActionBar().hide();

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>
