Toggle Passwortfeld jetpack compose

Hallo, ich versuche, visualTransformation dynamisch zu ändern, wenn der Benutzer auf die Schaltfläche „Kennwort anzeigen“ klickt. Ich kann das Passwort filtern, konnte es aber nicht im Klartext anzeigen. Irgendeine Idee dafür? Hier ist, was ich bisher bekommen habe.

fun UserInputText(
    keyboardType: KeyboardType = KeyboardType.Text,
    onTextChanged: (TextFieldValue) -> Unit,
    textFieldValue: TextFieldValue,
    visualTransformation: VisualTransformation = VisualTransformation.None,
    borderColor: Color = editTextBorderColor,
    keyboardShown: Boolean,
    onTextFieldFocused: (Boolean) -> Unit,
    focusState: Boolean,
    placeholder: String = "",
    modifier: Modifier = Modifier
) {
    Box(
        modifier = modifier.border(
            width = 2.dp,
            color = borderColor,
            shape = RoundedCornerShape(16.dp)
        )
    ) {
        var lastFocusState by remember { mutableStateOf(FocusState.Inactive) }
        val focusRequester = FocusRequester()
        val focusRequesterModifier = Modifier.focusRequester(focusRequester)

        BasicTextField(
            value = textFieldValue,
            onValueChange = { onTextChanged(it) },
            modifier =
            modifier.focus().then(focusRequesterModifier)
                .align(Alignment.TopStart)
                .focusObserver { state ->
                    if (lastFocusState != state) {
                        onTextFieldFocused(state == FocusState.Active)
                    }
                    lastFocusState = state
                },
            keyboardOptions = KeyboardOptions(
                keyboardType = keyboardType,
                imeAction = ImeAction.Send
            ),
            visualTransformation = visualTransformation,
            maxLines = 1,
            cursorColor = inputTextColor,
            textStyle = MaterialTheme.typography.body1.copy(color = inputTextColor)
        )
        if(keyboardType == KeyboardType.Password) {
            Image(
                vectorResource(id = R.drawable.ic_icons_watch_count_24), modifier = Modifier
                    .align(Alignment.TopEnd)
                    .padding(end = 16.dp, top = 16.dp).clickable(onClick = {})
            )
        }
    }
}

Sie können die Norm verwenden TextField zusammensetzbar:

var password by rememberSaveable { mutableStateOf("") }
var passwordVisible by rememberSaveable { mutableStateOf(false) }

TextField(
    value = password,
    onValueChange = { password = it },
    label = { Text("Password") },
    singleLine = true,
    placeholder = { Text("Password") },
    visualTransformation = if (passwordVisible) VisualTransformation.None else PasswordVisualTransformation(),
    keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.Password),
    trailingIcon = {
        val image = if (passwordVisible)
            Icons.Filled.Visibility
        else Icons.Filled.VisibilityOff

        // Please provide localized description for accessibility services
        val description = if (passwordVisible) "Hide password" else "Show password"

        IconButton(onClick = {passwordVisible = !passwordVisible}){
            Icon(imageVector  = image, description)
        }
    }
)

Hinweis: zu verwenden Icons.Filled.Visibility Und Icons.Filled.VisibilityOff füge die Abhängigkeiten hinzu: implementation "androidx.compose.material:material-icons-extended:$compose_version"

Überprüfen Sie dies:

    var passwordVisibility: Boolean by remember { mutableStateOf(false) }
    TextField(value = "Enter Password",
        visualTransformation = if (passwordVisibility) VisualTransformation.None else PasswordVisualTransformation(),
        leadingIcon = {
            IconButton(onClick = {
                passwordVisibility = !passwordVisibility
            }) {
                Icon(imageVector = vectorResource(id = R.drawable.ic_icons_watch_count_24))
            }
        },
        onValueChange = { })
