ActionBar items appear always in Overflow Menu

Question

I am trying to add actions item in action bar, but items always are adding into the overflow list even there is lot of room. Any suggestion to resolve this ??

This should be like this

main.xml

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

    <item
        android:id="@+id/action_refresh"
        android:icon="@drawable/ic_action_refresh"
        android:showAsAction="ifRoom"
        android:title="@string/action_refresh" />

    <item
        android:id="@+id/action_search"
        android:icon="@drawable/ic_action_search"
        android:showAsAction="ifRoom"
        android:title="@string/action_search" />

    <item
        android:id="@+id/action_settings"
        android:title="@string/action_settings"
        app:showAsAction="never" />


</menu>

MainActivity.java

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Answer 1

My app is using the Support Library for compatibility on versions as low as Android 2.2 so I have to define my own XML namespace and use that namespace as the attribute prefix

Solution was this, I was writing this android:showAsAction="ifRoom" but I should have app:showAsAction="ifRoom"

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

    <item
        android:id="@+id/action_refresh"
        android:icon="@drawable/ic_action_refresh"
        app:showAsAction="ifRoom"
        android:title="@string/action_refresh" />

    <item
        android:id="@+id/action_search"
        android:icon="@drawable/ic_action_search"
        app:showAsAction="ifRoom"
        android:title="@string/action_search" />

    <item
        android:id="@+id/action_settings"
        android:title="@string/action_settings"
        app:showAsAction="never" />


</menu>
