如何在Android中顯示Dialog時顯示ActionBar？即使出現對話框，我的ActionBar也應該啓用。 在我的應用程序中，當dilog出現時它變得很暗淡。

     layout.setOrientation(LinearLayout.VERTICAL); 
     tv.setText("Hi this is a sample text for popup window"); 
     layout.addView(tv, params); 
     popUp.setContentView(layout); 
     // popUp.showAtLocation(layout, Gravity.BOTTOM, 10, 10); 
     mainLayout.addView(but, params); 
     setContentView(mainLayout); 
    } 
}
