Action Buttons Doesn't Show Up on Action Bar

Action buttons doesn't show up on Action Bar?

This is because if you use the support AppCompat ActionBar library and ActionBarActivity you should create your menus in a different than the standard way of creating xml menus in ActioBarSherlock or the default ActionBar.

So try this code :

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
      xmlns:app="http://schemas.android.com/apk/res-auto">
      <item android:id="@+id/action_search"
          android:icon="@drawable/ic_action_search"
          android:title="@string/action_search"
          app:showAsAction="always"  />
      <item android:id="@+id/action_compose"
          android:icon="@drawable/ic_action_compose"
          android:title="@string/action_compose" 
          app:showAsAction="always"/>
</menu>

Action Button not showing in Action Bar

Change your code with the following and try again;

 <menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
    <item android:id="@+id/action_search"
        android:icon="@drawable/ic_action_search"
        android:title="@string/action_search"
        yourapp:showAsAction="always"  />
</menu>

Also make sure that you have the following part;

@Override
  public boolean onCreateOptionsMenu( Menu menu )
  {
    getMenuInflater().inflate( R.menu.main, menu );
    return true;
  }

action bar buttons not showing

i found the solution to my problem.
since i have been trying to use namespace

xmlns:app="http://schemas.android.com/apk/res-auto"

then i should use

app:showAsAction="ifRoom" 

instead of

android:showAsAction="ifRoom"

Android action buttons in action bar not appearing?

Since your Activity extends ActionBarActivity you would be using AppCompat from support library.

So change to

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
    <item android:id="@+id/action_add"
      android:icon="@drawable/ic_add"
      android:title="Add"
      yourapp:showAsAction="always"
       />
    ...
</menu>

Quoting docs

Notice that the showAsAction attribute above uses a custom namespace
defined in the tag. This is necessary when using any XML
attributes defined by the support library, because these attributes do
not exist in the Android framework on older devices. So you must use
your own namespace as a prefix for all attributes defined by the
support library.

Android action buttons are not showing in action bar, but they are in overflow menu

TO make an item appear directly in the action bar instead of the overflow use the yourapp:showAsAction ="ifRoom" just like the last line below

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
    <item android:id="@+id/action_search"
          android:icon="@drawable/ic_action_search"
          android:title="@string/action_search"
          yourapp:showAsAction="ifRoom"  />

</menu>

Unable to add action buttons to my action bar in android studio

<menu xmlns:android="http://schemas.android.com/apk/res/android"     
 xmlns:app="http://schemas.android.com/apk/res-auto">

<item
    android:id="@+id/action_settings"
    android:orderInCategory="1"
    app:showAsAction="always"
    android:icon="@drawable/ic_action_settings"
    android:title="@string/action_settings"/>
<item
    android:id="@+id/volume"
    android:orderInCategory="2"
    android:title="Volume"
    android:icon="@drawable/ic_action_volume_on"
    app:showAsAction="always"/>

You need to xmlns referencing res-auto and then use it as I have used in my code. Hope this helps.

Switch button not showing up in ActionBar?

your are getting error because your actionView is null. change your Switch menu code

<item
     android:id="@+id/toggle_test"
     android:title=""
     app:showAsAction="ifRoom"
     android:orderInCategory="1"
     android:actionViewClass="android.widget.Switch" /> 

to app:actionViewClass="android.widget.Switch" look carefully it would be app not android like this...

<item
      android:id="@+id/toggle_test"
      android:title=""
      app:showAsAction="ifRoom"
      android:orderInCategory="1"
      app:actionViewClass="android.widget.Switch" /> 

and now change your java code like this

final MenuItem toggleservice = menu.findItem(R.id.toggle_test);
Switch actionView=(Switch) MenuItemCompat.getActionView(toggleservice );
actionView.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        // Start or stop your Service
    }
});

Action bar buttons only showing in the overflow

Try this app:showAsAction="always"

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.mhmt.autotextmate.Main" >

<!-- New, should appear as action button -->
<item
android:id="@+id/action_new"
android:icon="@drawable/ic_action_new"
app:showAsAction="always"
android:title="@string/action_new"/>
<!-- Settings, should always be in the overflow -->
<item
android:id="@+id/action_settings"
android:icon="@drawable/ic_action_save"
app:showAsAction="always"
android:title="@string/action_settings"/>

Action Bar doesn't show up

Ok guys I got the solution to my very own problem.
The problem was in defining the action items in the "menu.xml".
Android documentation says you cannot use "android:showAsAction" on older devices as it does not exist in older versions. You have to use a custom namespace. Instead of saying "android:showAsAction", use "app:showAsAction" and you are good to go. Here is the attachment from official page:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
    <item android:id="@+id/action_search"
          android:icon="@drawable/ic_action_search"
          android:title="@string/action_search"
          yourapp:showAsAction="ifRoom"  />
    ...
</menu>

Using XML attributes from the support library:

Notice that the showAsAction attribute above uses a custom namespace defined in the tag. This is necessary when using any XML attributes defined by the support library, because these attributes do not exist in the Android framework on older devices. So you must use your own namespace as a prefix for all attributes defined by the support library.

I hope it helps someone out there.
