Android Studio - Action Bar remove

问题:

I'm trying to remove/disable the ActionBar. I tried to put in the Manifest:

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

and it doesn't work. It doesn't remove the ActionBar. Please help me. Thanks.

回答1:

in your oncreate() method use this

getActionBar().hide();

If your minSdkVersion is 10 or lower, instead use:

getSupportActionBar().hide();

回答2:

I had this issue too. I went to styles.xml and changed

parent="Theme.AppCompat.Light.DarkActionBar" 

to

parent="Theme.AppCompat.Light.NoActionBar"

and that removed it from all my activities.

回答3:

You can try this. It works for me

Add it in style.xml

<style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
      <item name="windowActionBar">false</item>
      <item name="windowNoTitle">true</item>
      <item name="android:windowFullscreen">true</item>
</style>

and use the style at manifest.xml.

android:theme="@style/AppTheme.NoActionBar"

回答4:

getActionBar().hide();

I think this should work.

回答5:

For android studio You can go to styles.xml and change parent="Theme.AppCompat.Light.DarkActionBar" to parent="Theme.AppCompat.Light.NoActionBar" and in Eclipse it can be changed in manifest file

  <activity
        android:name="com.ExcellenceTech.webview.MainActivity"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Holo.Light.NoActionBar.Fullscreen" >

You hide action bar by with different ways.

1.action bar hidden through the manifest xml file (non Java Programming), then the easy way is to add the following attribute in Activity tag:

 android:theme="@style/Theme.NoActionBar"

If custom Theme is created then it is convenient to create another style extending the custom theme.

 <item name="android:windowActionBar">false</item>
 <item name="android:windowNoTitle">true</item>

or

ActionBar actionBar = getActionBar(); OR getSupportActionBar();
actionBar.hide();

getSupportActionBar().hide(); 
  or 
getActionBar().hide();

回答7:

In AndroidManifest.xml and acitivity section put this code.

android:theme="@style/Theme.AppCompat.Light.NoActionBar"

回答8:

getActionBar().hide();

or

getSupportActionBar().hide();

But the change might not appear in the xml design.
