背景顏色回舊Android版本

我正在開發與版本17（與Galaxy Nexus）爲Android的用戶界面，並且，我得到了背景白色。當我在版本15（與Galaxy II）中嘗試相同的代碼時，背景是黑色的。那麼，如果代碼相同，爲什麼顏色不同呢？背景顏色回舊Android版本

另一個問題是，我正在使用TextView的函數setBackground，它只適用於版本16或更新版本。它是setBackgroundResourse的等價物嗎？

這是我製作代碼的一個例子。

FrameLayout frame = new FrameLayout(this); 
     frame.setId(findId()); 
     FrameLayout.LayoutParams frameParams = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,FrameLayout.LayoutParams.MATCH_PARENT);    
     frame.setBackgroundResource(idBorder); 
     frame.setLayoutParams(frameParams); 


     //Relative layaout que engloba todo 
     RelativeLayout relativeLayout = new RelativeLayout(this); 
     //relativeLayout.setId(findId()); 
     RelativeLayout.LayoutParams relativeParams = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);  
     relativeLayout.setLayoutParams(relativeParams);   
     relativeLayout.setPadding(5, 5, 5, 5); 
     relativeParams.addRule(RelativeLayout.CENTER_HORIZONTAL); 
     relativeParams.addRule(RelativeLayout.CENTER_VERTICAL); 
     relativeLayout.setBackgroundColor(Color.WHITE); 
     //relativeLayout.setBackground(getResources().getDrawable(idBorder)); 
     relativeLayout.setBackgroundResource(idBorder); 
     frame.addView(relativeLayout); 

     //Nombre de la sala 
     TextView textRoomName = new TextView(this); 
     textRoomName.setId(findId()); 
     relativeLayout.addView(textRoomName); 

     textRoomName.setText(room.getName()); 
     RelativeLayout.LayoutParams relativeParamRoomName = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);  
     relativeParamRoomName.addRule(RelativeLayout.ALIGN_PARENT_LEFT);  
     relativeParamRoomName.setMargins(10, 10, 10, 5);  
     textRoomName.setLayoutParams(relativeParamRoomName); 
     textRoomName.setTextColor(Color.parseColor("#040404")); 
     textRoomName.setTextSize(20); 
     textRoomName.setTypeface(null, Typeface.BOLD); 
     textRoomName.setPadding(3, 3, 3, 3);   
     //textRoomName.setBackground(getResources().getDrawable(idBorder)); 
     textRoomName.setBackgroundResource(idBorder);
