Writing in EditText with gestures


This question caught my eye because it is something I would like to do in the future for a non-English language. These are my thoughts:

Observe what other people have done

This helps to know what is possible, where to start, and where to go. Here are some things I have found:

Other SO questions:

Start simple and gradually support more complex input

When I approach a complex topic like handwriting recognition, I try to break it down into a list of simple tasks. If any one of the tasks is too difficult, then break that task down even further. Follow the cyclical pattern of research, try out a new idea, and improve on it.

My list to break down this project:

  • learn how to do simple gesture detection (tutorial 1, tutorial 2) (tutorial 3 from @jmunoz's answer)
  • make an app that recognizes single letters individually
  • string the letters into words (maybe adding a letter after a MotionEvent.ACTION_UP)
  • recognize whole scribbled words (this is already possible in Chinese, thought I haven't seen it in English)

Fling gestures not executing
The one piece that you are missing is that you are not sending the activity's touch events to your listener. Assuming that you want to detect gestures on your GameView object, the one line you need, after constructing the listener, is: gameView.setOnTouchListener(gestureListener);

How to add one to value of EditText in Android
String actually concats 1. so "1"+"1"="11". So you have to first convert it to int and add 1 and then reconvert it to String and set it to EditText. So change this line mRentPriceText.setText(rentPrice+1); to mRentPriceText.setText(Integer.toString(rentPrice+1));

Android afterTextChanged get EditText tag
If you would declare your txtQuantity as final and then pass an anonymous new TextWatcher() { ... } into the addTextChangedListener, then you could directly use txtQuantity inside the afterTextChanged(Editable s) method. Hope this helps.

Issue with edittext in TextWatcher
My main issue is I can only input 1 character and then it shows me or error or checked icon and it goes to the next field. Issue is: You are calling the validation method in onTextChanged. So its going in hasText method, determines there is less than 3 characters, and shows error. In your case, its better to implement using OnFocusChangeListener Example: myEditText.setOnFocusChangeListen
