全屏显示Dialog的设置

下面是Dialog的style:
01.<!-- 全屏dialog样式 左右插入 -->  
02.    <style name="mydialog" parent="@android:style/Theme.Dialog">  
03.        <item name="android:windowFrame">@null</item>  
04.        <item name="android:windowIsFloating">true</item>  
05.        <item name="android:windowIsTranslucent">true</item>  
06.        <item name="android:windowNoTitle">true</item>  
07.        <item name="android:backgroundDimEnabled">false</item>  
08.        <item name="android:windowBackground">#FFFFFF</item>  
09.    </style>  

 下面是创建Dialog的代码：

01.Dialog dialog = new Dialog(Activity.this, R.style.mydialog);  
02.dialog.setContentView(R.layout.layout);  
03.LayoutParams lay = dialog.getWindow().getAttributes();  
04.setParams(lay);  
05.dialog.show(); 

 下面是设置Dialog的LayoutParams的属性方法：

01.private void setParams(LayoutParams lay) {  
02.  DisplayMetrics dm = new DisplayMetrics();  
03.  getWindowManager().getDefaultDisplay().getMetrics(dm);  
04.  Rect rect = new Rect();  
05.  View view = getWindow().getDecorView();  
06.  view.getWindowVisibleDisplayFrame(rect);  
07.  lay.height = dm.heightPixels - rect.top;  
08.  lay.width = dm.widthPixels;  
09. }
