Android Question Screen Shot

[gballa]

Hi All,

I am a newbie to B4A and need some help.

I am using this code to take a screen shot

Dim x As B4XView = Activity
Dim bmp As B4XBitmap = x.GetBitmap

I have an ImageView in the program and need to display the Screen shot in that ImageView

I tried

ImageView1.BitMap=bmp

but keep getting this error
java.lang.RuntimeException: Object should first be initialized (B4XBitmap).

How can I convert a B4xBitmap to an ImageView bitmap?

Thanks

... and so the best thing you can do is use B4XPages right away.

In your case you would use:

Dim xBmp As B4XBitmap = Root.SnapShot
Dim xIV As B4XImageView


xIV.Bitmap = xBmp

Otherwise you could use this:

passing it Activity.

Activity screenshot not showing rounded panel

I have a problem with taking screenshots. I have a B4ximageview inside a rounded panel. It shows well in-app, the problem occurs when I take the screenshot of the activity, the bitmap I get does not show the image in the rounded panel, it basically just shows the square image. I replicated it...
