iOS Question LoadBitmap works in b4a not in b4i

[John Woodsmall]

I need to set the background from an image of the main page(activity)

Activity.SetBackgroundImage(File.DirAssets,"blue.jpg"))

But this is not in b4i?
How do I set the background of the main page to an image file?

This question has nothing to do with LoadBitmap keyword.

You need to add an ImageView (use anchors to make it fill the page) and then set the bitmap to the ImageView.

ok I did the imageview (it covers the whole page...)
what I have now is:

Page1
.RootPanel.Color = Colors.Magenta

NavControl.ShowPage(Page1)

Page1.RootPanel.LoadLayout("AstroMatch")


how do I get the imageview to be the backgound? like in the b4a?

sorry if this is a stupid question...but I am forced to get this right.
it is wonderful that I have come this far with your stuff, so thanks!

Where did you add the ImageView ?
What do you have in the "AstroMatch" layout ?
Put the ImageView onto the layout, add the image file to the ImageView and set it to back.

Put the ImageView onto the layout, add the image file to the ImageView and set it to back.

where do I set it to "back" ?

 

[Erel]

You should add the ImageView with the designer.

 

[John Woodsmall]

ok...I did that, but the image fills the screen, I need it as the background to the main page.
Can this be done?
the question is, can an image be a background? if so how?
this was so easy in b4a.

 

[Erel]

In the designer right click on the ImageView and send it to back.

 

[John Woodsmall]

ok...that tries to fill the background screen thanks...
but it does not go all the way up to the top or to the bottom.
see:http://109.65.102.145:25613/?method=file&file=5995426940995616039.html
I put the top/right to both.

what am i missing here?

 

[Erel]

It is not possible to share those links. They expire after 10 minutes.

Check the anchors. It should look like:

 

[John Woodsmall]

it does in the designer.

 

[Erel]

Can you upload your layout file?

 

[John Woodsmall]

ok
What I found out was that I had a color for the main page.
I switched it to transparent and NOW the back image shows thru out the app.
it is still alittle short of the top.
how do I upload the layout file?
my project is called "AstroMatch" so what is the layout file name?
(I tried several of the possible names...but I got not allowed in the "Upload File" button to the right on this page.)

where is it?

 

[John Woodsmall]

here is:AstroMatch.bal...

 

[Erel]

The anchors are correct however it is not positioned correctly:

All four values should be 0.

Note that you can also set it in the designer script:

ImageView1.SetLeftAndRight(0, 100%x)
ImageView1.SetTopAndBottom(0, 100%y)

 

[John Woodsmall]

I tried the scipt and it did not work.
Unknown member
also set the parameters 0,0,0,0 same look did totally fill the background.

 

[Erel]

Don't you want to fill the complete background?

Make sure you call the correct view name in the designer. It will work.

 

[John Woodsmall]

Yes...I want to fill the whole background(mis-type above)


fails in designer script.

 

[Erel]

Please upload the project with the code that files in the designer script (File - Export as zip).

 

[John Woodsmall]

after you have downloaded the zip file above...please delete it from this thread.
thanks
