Android Dialog

1. Android提供了对话框支持，包括如下类别：
• AlertDialog:功能最丰富，应用最广泛的对话框
• ProgressDialog:进度条对话框
• DataPickerDialog:日期选择对话框
• TimePickerDialog:事件选择对话框
  
  
2. 自定义Dialog

   //Style.xml代码 
   <style name="FullScreenDialog" parent="android:style/Theme.Dialog"> 
       <item name="android:windowNoTitle">true</item> 
       <item name="android:windowFrame">@null</item> 
       <item name="android:windowIsFloating">true</item> 
       <item name="android:windowIsTranslucent">false</item> 
       <item name="android:background">@android:color/black</item> 
       <item name="android:windowBackground">@null</item> 
       <item name="android:backgroundDimEnabled">false</item> 
   </style>

   使用AlertDialog的上层接口类：
    
   Dialog reNameDialog = new Dialog(getContext(), R.style.FullScreenDialog); 
   LayoutInflater mLayoutInflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
   View reNameView = mLayoutInflater.inflate(R.layout.audiorecord_rename, null); 
   LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); 
   reNameDialog.addContentView(reNameView, params); 
   reNameDialog.show();
