启动App时获取屏幕宽高
App.cs里面添加：
publicstaticdoubleScreenWidth;
publicstaticdoubleScreenHeight;
Android下 MainActivity.cs里面添加：
protectedoverridevoidOnCreate(Bundlebundle)
{
TabLayoutResource=Resource.Layout.Tabbar;
ToolbarResource=Resource.Layout.Toolbar;
base.OnCreate(bundle);
global::Xamarin.Forms.Forms.Init(this,bundle);
varwidth=Resources.DisplayMetrics.WidthPixels;
varheight=Resources.DisplayMetrics.HeightPixels;
vardensity=Resources.DisplayMetrics.Density;//屏幕密度
App.ScreenWidth=width / density;//屏幕宽度
App.ScreenHeight=height / density;//屏幕高度含24个单位的标题栏高度通过OnSizeAllocated获取的高度不含标题栏高度
LoadApplication(newApp());
}
IOS下AppDelegate.cs里面添加：
publicoverrideboolFinishedLaunching(UIApplicationapp,NSDictionaryoptions)
{
global::Xamarin.Forms.Forms.Init();
App.ScreenWidth=UIScreen.MainScreen.Bounds.Width;//屏幕宽度
App.ScreenHeight=UIScreen.MainScreen.Bounds.Height;//屏幕高度
LoadApplication(newApp());
returnbase.FinishedLaunching(app,options);
}
