Text Input
The text input allows the person using your app to type in anything that they want such as words, passwords or numbers.
You can choose from the following types of keyboards:
- Default keyboard: Displays your device’s default keyboard
- Email Address: Displays an alphanumeric keyboard to accept email addresses
- Numeric: Displays a keypad with only numbers; It is similar to the phone pad keyboard
- Phone Pad: Displays a telephone keypad; It is similar to the numeric keyboard
You can also set up Text Input for passwords as shown below using the Secure Text Entry Switch. This switch will replace text with * as users type.
To activate Secure Text Entry, look for the Text Input Style properties and make sure that the Secure Text Entry switch is set to true.
You can customize the Text Input component with the following properties:
- Hint: Hint text that disappears when the user starts typing into the Text Input
- Text: Text that appears on the text input
- Visible: To see the text input in your app, set the switch to true
- Border
- Width: Enter how wide you want the border outline of the text input to be
- Color: Pick a color for the border of the text input
- Style: Select if you want the border to be a dotted, dashed or solid line
- Radius: Enter how round you want the edges of the border for the text input to be
You can set how tall the text input is using the Height property and set how wide the text input is using the Width property.
