android - Is it possible to inflate a CustomLayout : FrameLayout in Xamarin in its own constructors and own class methods? -

here illustration inflate... framelayout , have layout axml file... inflate layout parent of framelayout (a fragment)... want custom framelayout in other fragments. in method initialize() compiler says error cs1604: cannot assign '' because read-only (cs1604) (myproject.mono) , error cs0266: cannot implicitly convert type 'android.widget.framelayout' 'myproject.mono.viewartistalbumtrack'. explicit conversion exists (are missing cast?) (cs0266) (navi.mono)

}

i think issue may line:

= (framelayout)inflater.inflate(resource.layout.viewaat, null);

that isn't right way load layout in view. if view custom framelayout kid views inflate xml framelayout , take references views within e.g.

var frame = (framelayout)inflater.inflate(resource.layout.viewaat, null); this.trackdown = frame.findviewbyid<button>(...); // find other views here

android xamarin custom-controls layout-inflater framelayout
