Hi, Just wondering if anyone has opinion on this.

I have the following code:

@Composable
fun SomeTextField(value: String, onChange: (String) -> Unit, ...) {
    ...
    TextField(
        value = value,
        onValueChange = onChange,
        ...,
         keyboardOptions = KeyboardOptions(
            keyboardType = KeyboardType.NumberPassword,
            imeAction = if (someState) ImeAction.Go else ImeAction.Done,
        ),
    )
    ...
}

this line:

imeAction = if (someState) ImeAction.Go else ImeAction.Done,

causes the ios keyboard to hide and immediately show back up. I was wonder if doing so in compose is not advisable?

[Andy Dent]

Immediate thought - what exactly is your someState?
I’m still fairly new to CMP but if that was some kind of binding, I could see it causing grief with state changes. I really have no feel yet for which bits of CMP cause there to be active things that rebuild visual stuff.

I would do a quick test with a local val set to true and then to false and see if it’s the expression or the expression result changing that causes keyboard flickers

I’ve already tested it and it is the exact cause of the keyboard flicker.

for this specific scenario for someState, it could be a verification of the input (isValidEmail or isInputComplete) where if the input does not fit the validation, the ImeAction should show Done, but when it passes the validation it should show Go.

What I don’t know at the moment is whether such behavior is intended or whether this is a valid bug to report.

[Andy Dent]

The nuance I was thinking was, if you’re able to copy a more dynamic bound result to a local var, it may help

[Andy Dent]

But my head is in SwiftUI for a couple of days so that’s maybe affecting my thinking

[Archie]

At the moment, someState is already local to the composable if thats what you meant.

[Andy Dent]

Uggh, yeah sorry, ignore me, pretty sure my idioms are coming more from SwiftUI states than Compose. I’m doing something very similar in a screen I’m working on at present to choose between a numeric pad and one with decimal.

No worries thanks for the input.
