假设您有一个带有 ID 的相对布局relativeLayout
。您可以使用以下方法设置背景:
RelativeLayout rLayout = (RelativeLayout) findViewById(R.id.relativeLayout);
Resources res = getResources(); //resource handle
Drawable drawable = res.getDrawable(R.drawable.newImage); //new Image that was added to the res folder
rLayout.setBackgroundDrawable(drawable);

试试这个 Xamarin.Android(跨平台)
相对布局 relativeLayout = new RelativeLayout (this);
或
RelativeLayout relativeLayout = (RelativeLayout)FindViewById (Resource.Id.relativeLayout);
relativeLayout.SetBackgroundDrawable (Resources.GetDrawable (Resource.Drawable.imageName));
