The Right Keyboard Matters
Asking for a phone number? Show a number pad, not letters. The right keyboard makes typing fast and error-free. 📱
keyboardOptions
You shape the keyboard through keyboardOptions. It lets you pick the key layout and the action button shown on it.
TextField(
value = phone,
onValueChange = { phone = it },
keyboardOptions = KeyboardOptions(/* ... */)
)Pick a keyboardType
Set keyboardType to match the data: Number for digits, Email for addresses, Phone for dialing.
keyboardOptions = KeyboardOptions(
keyboardType = KeyboardType.Email
)Common Keyboard Types
Handy choices include Text, Number, Phone, Email, Decimal, and Password. Each one tweaks the keys to fit the input.
Hide Password Characters
For secrets, pair the Password type with a visualTransformation so each character shows as a dot. 🔒
visualTransformation = PasswordVisualTransformation()IME Actions
The imeAction sets the keyboard's main button. Choose Next to move to the following field or Done to finish a form.
keyboardOptions = KeyboardOptions(
imeAction = ImeAction.Next
)Common IME Actions
Frequent actions are Next, Done, Search, Send, and Go. They tell the user what tapping the button will do.
React with keyboardActions
Respond to that button using keyboardActions. Run a search, submit the form, or jump focus to the next field.
keyboardActions = KeyboardActions(
onDone = { submitForm() }
)Move Focus on Next
For multi-field forms, use the FocusManager to move to the next input when the user taps Next.
keyboardActions = KeyboardActions(
onNext = { focusManager.moveFocus(FocusDirection.Down) }
)Type and Action Work Together
Set the keyboardType and imeAction together for each field. The result feels polished and effortless to fill in.
Small Touches, Big Polish
Matching the keyboard and its action to each field is a tiny effort that gives your forms a truly professional feel.
