显示隐藏布局/控件
   
   
可以写在点击事件中
   
   
layoutID.setVisibility(View.VISIBLE);//这一句显示布局LinearLayout区域
   
   

   
   
layoutID.setVisibility(View.GONE);//这一句即隐藏布局LinearLayout区域
   
   

   
   
monitor_area1.setVisibility(View.VISIBLE);//显示控件
   
   

   
   
monitor_area1.setVisibility(View.INVISIBLE);//隐藏控件
   
   

   
   
View.VISIBLE--->可见
   
   
View.INVISIBLE--->不可见，但这个View仍然会占用在xml文件中所分配的布局空间，不重新layout 
   
   
View.GONE---->不可见，但这个View在ViewGroup中不保留位置，会重新layout，不再占用空间，那后面的view就会取代他的位置，
