自定義操作欄上的下拉菜單

Question

我想要做的是建立一個圖像按鈕的操作欄，我想要做的是當我按下按鈕下拉菜單中有三個項目，每次我按它帶我到正確的活動項目。這裏是我的代碼：

這裏是操作欄中的xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="50dp" 
    android:background="@drawable/black_pattern" > 

    <TextView 
     android:id="@+id/title_text" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerInParent="true" 
     android:textAllCaps="true" 
     android:textAppearance="?android:attr/textAppearanceLarge" 
     android:textColor="#fff" 
     android:textStyle="bold" /> 

    <ImageView 
     android:id="@+id/imageView1" 
     android:layout_width="35dp" 
     android:layout_height="35dp" 
     android:layout_alignParentLeft="true" 
     android:layout_centerVertical="true" 
     android:layout_marginLeft="8dp" 
     android:src="@drawable/ic_launcher" /> 

    <ImageButton 
     android:id="@+id/imageButton" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentRight="true" 
     android:layout_centerVertical="true" 
     android:layout_marginRight="8dp" 
     android:background="@null" 
     android:src="@android:drawable/ic_menu_rotate" /> 

</RelativeLayout> 

這裏是Java文件：

公共類MainActivity擴展活動{

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

     ActionBar mActionBar = getActionBar(); 
     mActionBar.setDisplayShowHomeEnabled(false); 
     mActionBar.setDisplayShowTitleEnabled(false); 
     LayoutInflater mInflater = LayoutInflater.from(this); 

     View mCustomView = mInflater.inflate(R.layout.custom_actionbar, null); 
     TextView mTitleTextView = (TextView) mCustomView.findViewById(R.id.title_text); 
     mTitleTextView.setText("My Own Title"); 

     ImageButton imageButton = (ImageButton) mCustomView 
       .findViewById(R.id.imageButton); 
     imageButton.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View view) { 
       Toast.makeText(getApplicationContext(), "Refresh Clicked!", 
         Toast.LENGTH_LONG).show(); 
      } 
     }); 

     mActionBar.setCustomView(mCustomView); 
     mActionBar.setDisplayShowCustomEnabled(true); 
    } 

} 

所以我需要是當我點擊圖像按鈕，下拉使用下面的值列表顯示：

String[] actions = new String[] { 
     "Bookmark", 
     "Subscribe", 
     "Share" 
    }; 

，每個人帶我到正確的活動，我在安卓新..請幫助..
