使用Appcompat v7库时，ActionBar中未显示溢出图标

Question

ok...i have tried all the stackoverflow solutions. None of them seems to work.

Manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.firstapp"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name="com.example.firstapp.DisplayMessageActivity"
            android:label="@string/title_activity_display_message"
            android:parentActivityName="com.example.firstapp.MainActivity"
            android:theme="@style/Theme.AppCompat.Light" >
            <meta-data
                android:name="android.support.PARENT_ACTIVITY"
                android:value="com.example.firstapp.MainActivity" />
        </activity>
        <activity
            android:name="com.example.firstapp.MainActivity"
            android:label="@string/app_name"
            android:theme="@style/Theme.AppCompat.Light" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Inside /res/menu/main_activity_actions.xml

<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/title_search"
        yourapp:showAsAction="ifRoom"/>
    <item
        android:id="@+id/action_share"
        android:icon="@drawable/ic_action_share"
        android:title="@string/title_share"
        yourapp:showAsAction="ifRoom"
        />
    <item
        android:id="@+id/action_settings"
        android:icon="@drawable/ic_action_settings"
        android:title="@string/title_settings"
        yourapp:showAsAction="ifRoom"/>
</menu>

Inside main activity

public boolean onCreateOptionsMenu(Menu menu)
    {
        getMenuInflater().inflate(R.menu.main_activity_actions, menu);
        return super.onCreateOptionsMenu(menu);
    }

Here is the screen shot.

Horizontal Screen

According to me the last icon in ActionBar should automatically go in overflow as stated in the google document. However, its not happening. Whats wrong here ?

Add this code in onCreate method of those activities in which you want to show icon-

try {
            ViewConfiguration config = ViewConfiguration.get(this);
            Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey");
            if(menuKeyField != null) {
                menuKeyField.setAccessible(true);
                menuKeyField.setBoolean(config, false);
            }
    } catch (Exception ex) {
            // Ignore
}
