Android Question Custom Toast Message - Additional methods

[LucaMs]

I tried to use other methods in the code snippet "Custom Toast Message".

1:

' Seems to not work.
   Dim horizontalMargin, verticalMargin As Float
   horizontalMargin = 50 '%
   verticalMargin = 25 ' %
   toast.RunMethod("setMargin", Array (horizontalMargin, verticalMargin))

2:

Dim pnl As Panel
...
toast.RunMethod("setView", pnl)
' incompatible types: ViewGroup cannot be converted to Object[]
' Error even if I use a simple Label.

Also, is there a way to increase the size of the toast?

[I used this and it is useful enough:
cs.Initialize.Color(Colors.Blue).Size(50).Append("Custom" & CRLF & CRLF & "Toast").PopAll

(I know, I should use smart strings in my code )
]

Where does this code come from? Which error did you get?

The toast message should be large enough to hold the content. It grows automatically.

Where does this code come from?

https://developer.android.com/reference/android/widget/Toast.html#setMargin(float, float)
https://developer.android.com/reference/android/widget/Toast.html#setView(android.view.View)

Which error did you get?

1. No errors - I thought to be able to change the toast position using that method.

2. That method requires a View (Java) as parameter; is not a b4a Label an Android Java View?

1. The code is correct, though it is missing dip units. If it doesn't work then this method doesn't do what you want it to do.
You can call setGravity as in the commented code: https://www.b4x.com/android/forum/threads/custom-toast-message.89173/

2. It should be Array(pnl)

 

[LucaMs]

though it is missing dip units.

"horizontalMargin float: The horizontal margin, in percentage of the container width,"

If it doesn't work then this method doesn't do what you want it to do.

Almost certainly; who knows what his purpose is, then

2. It should be Array(pnl)

Could this be due to the initialization mode?

    Dim toast As JavaObject
toast = toast.InitializeStatic("android.widget.Toast").RunMethod("makeText", Array(ctxt, Text, duration))

2. This is the same case as the other point. setView doesn't do what you expect it to do.
