Item with App:Showasaction Not Showing

Item with app:showAsAction not showing

Things you should always check when you want to use action bar are

1) Extend ActionBarActivity instead of Activity

public class MainMenu extends ActionBarActivity{

2) Have the right style selected as defined at manifest

Manifest

<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >

Style

    <style name="AppTheme"
    parent="Theme.AppCompat.Light.DarkActionBar">
    </style>

3) Select the right title for showAsAction

  <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>

This is what most people get wrong

4) Define your Menu in Activity

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu items for use in the action bar
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main_activity_actions, menu);
    return super.onCreateOptionsMenu(menu);
}

If you do all the following your action bar should work.

Then you should add the onClickListener for every position...

Android appcompat actionbar menu item showAsAction not working

Whew, thanks for your help guys but I managed to figure it out. It wasn't a problem with the xml, it was a problem with the onCreateOptionsMenu function.

I was using this

new MenuInflater(getApplication()).inflate(R.menu.activity_wentry_editor, menu); 

instead of this

MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.activity_wentry_editor, menu);

Not entirely sure why this works but it does.

Items not showing in the ActionBar with showAsAction=“always”

try android:showAsAction instead of app:showAsAction. Or if you're using the appcompat_v7 backport, use both android:showAsAction and app:showAsAction(Thanks to Commonsware).

app:showAsAction=ifRoom not working

You need to try adding orderInCategory attribute. Something like this:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item android:id="@+id/shop_by"
        android:icon="@drawable/ic_shop_by"
        android:title="@string/shop_by_title"
        android:orderInCategory="100"/>
    <item android:id="@+id/search"
        android:icon="@drawable/ic_search"
        android:title="@string/search"
        android:orderInCategory="99"
        app:showAsAction="ifRoom"/>
</menu>

Use app:showAsAction="always" if you want to always show the menu item.

Note: the answer is updated from xmlns:app="http://schemas.android.com/res-auto" to xmlns:app="http://schemas.android.com/apk/res-auto"

kudos to @MikeM

Appcompat toolbar showAsAction doesn't work properly

As i can see from the resource file, you're grouping 5 items together. Try to put the items you want to always show on the AppBar outside that group. It should do the trick.

Android menu item set to always be shown is not being shown

Instead of app:showAsAction change it to android:showAsAction as shown:

<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="myAppID.MainActivity" >
      <item android:id="@+id/action_one"
          android:title="One"
          android:icon="@drawable/your_icon"
          android:showAsAction="always" />
      <item android:id="@+id/action_two"
          android:title="Two"
          android:showAsAction="never" />
      <item android:id="@+id/action_three"
          android:title="Three"
          android:showAsAction="never" />
  </menu>

Hope it works.

ActionBar showAsAction not working

app:showAsAction is used with AppCompatActivity. You must either extend that class and use AppCompat or use android:showAsAction.

app:showAsAction ifRoom is not working on appcompat action bar

Please Try to use
android:showAsAction="ifRoom|withText" instead of app:showAsAction="ifRoom|withText"

Action Items not showing in ActionBar with showAsAction=ifRoom

I found the problem. There was an error in the menu .xml file. In fact, I've added a new namespace:

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

But then, I still refer the property as if it belongs to the android namespace:

android:showAsAction="ifRoom"

The right way to refer this property is to use:

app:showAsAction="ifRoom"

Cause it belongs to the namespace app.

Here is the relevant part in documentation:

If your app is using the Support Library for compatibility on versions
as low as Android 2.1, the showAsAction attribute is not available
from the android: namespace. Instead this attribute is provided by the
Support Library and you must define your own XML namespace and use
that namespace as the attribute prefix. (A custom XML namespace should
be based on your app name, but it can be any name you want and is only
accessible within the scope of the file in which you declare it.)
