Monodroid：从资产或资源/可绘制文件中的文件设置imageview图像以配置SampleSize

Question

I want so set the samplesize of my image before I set it to the imageview . The problem is, that my application crashes if I set the image directly to imageview . (because needs too much memory!?)

Here's my code:

ImageView iv = FindViewById<ImageView>(Resource.Id.imagePusher);
Android.Graphics.BitmapFactory.Options options = new Android.Graphics.BitmapFactory.Options();
options.InSampleSize = 2;

Android.Graphics.Bitmap bMap = Android.Graphics.BitmapFactory.DecodeFile("the_path_I_want_to_know/image.jpg", options);

iv.SetImageBitmap(bMap);

Answer 1

Thank you Candide for help, now it works with the following code:

ImageView iv = FindViewById<ImageView>(Resource.Id.imagePusher);

Android.Graphics.BitmapFactory.Options options = new Android.Graphics.BitmapFactory.Options();
options.InSampleSize = 2;

Stream bitmap = Assets.Open("myimage.jpg");

Android.Graphics.Bitmap bMap = Android.Graphics.BitmapFactory.DecodeStream(bitmap, null, options);


iv.SetImageBitmap(bMap);
