I cannot seem to save a layout and its view components as a bitmap.
I am looking to implement something similar to these example, Create image from view/screen in Android , Convert frame layout into image and save it
The problem I am having is in regards to methods like GetDrawingCache(), and DrawingCacheEnabled(). It appears as if I cannot call them on a layout.
Here are the ERRORS
Error CS0201: Only assignment, call, increment, decrement, await, and new object expressions can be used as a statement (CS0201) (APPNAME)
Error CS1501: No overload for method 'GetDrawingCache' takes 0 arguments (CS1501) (APPNAME)
I am currently coding in Monodroid/Xamarin. So the methods will seem a little different, but maybe someone can provide some insight.
ImageActivity
Here I am adding the views programmatically to a layout.
protected override void OnCreate (Bundle savedInstanceState)
{
base.OnCreate (savedInstanceState);
image = new ImageView (this);
//image = FindViewById<ImageView> (Resource.Id.imageView1);
//this.image.SetScaleType (ImageView.ScaleType.CenterInside);
//this.image.LayoutParameters = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MatchParent, ViewGroup.LayoutParams.MatchParent);
SetContentView (Resource.Layout.Image);
m_Layout = FindViewById<FrameLayout> (Resource.Id.editable_layout);
m_Layout.AlwaysDrawnWithCacheEnabled;
this.path = (savedInstanceState ?? Intent.Extras).GetString ("path");
Title = System.IO.Path.GetFileName (this.path);
Cleanup ();
DecodeBitmapAsync (path, 400, 400).ContinueWith (t => {
image = FindViewById<ImageView> (Resource.Id.imageView1);
image.SetImageBitmap (this.bitmap = t.Result);
}, TaskScheduler.FromCurrentSynchronizationContext ());
btnAddImage1 = FindViewById<ImageButton> (Resource.Id.button1);
btnAddImage2 = FindViewById<ImageButton> (Resource.Id.button2);
btnAddImage2 = FindViewById<ImageButton> (Resource.Id.imageButton2);
btnAddImage1.Click += (sender, e) => {
CustomImageView bitmapView = new CustomImageView (this, Resource.Drawable.big85);
m_Layout.AddView (bitmapView);
};
btnAddImage2.Click += (sender, e) => {
CustomImageView bitmapView = new CustomImageView (this, Resource.Drawable.curled5);
m_Layout.AddView (bitmapView);
};
btnConfirm.Click += (sender, e) => {
createBitmap();
};
}
public void createBitmap(){
m_Layout.DrawingCacheEnabled;
m_Layout.BuildDrawingCache ();
Bitmap m_Bitmap = Bitmap.CreateBitmap(m_Layout.GetDrawingCache());
}
