Check text only if typed

MIT App Inventor Help

Hello guys,

I have a problem. I have an if block that checks if the text typed maches the selected list item, but it sets the label to incorrect even if the text is blank.

Is there a way I can make it check the text only if something is typed?

You can use the is empty block, found in the text drawer.

Hello Dennis

Use Lost Focus to determine that the typing has potentially finished. If the 'Is Empty Block 'returns true, pop-up a notifier to ask the User to Type the text, else use your 'is it correct' test.
