Estoy creando un teclado para android 2.2 y superior. todo está bien, pero cuando escribo realmente rápido, entonces mi método ACTION_DOWN no está llamando. corriente real de llamada método debe ser similarSoftKeyboard para android
1) motionEvent.ACTION_DOWN
2) OnPress()
3) motionEvent.ACTION_UP
4) OnRelease() and repeat same order for next word.
si escribo a velocidad normal entonces funciona bien, pero si escribo rápido, entonces por encima de orden de ejecución del método se parece
1) motionEvent.ACTION_DOWN
2) OnPress()
3) OnRelease()
4) motionEvent.ACTION_UP and for next word OnPress and OnRelease() methods are being called.
alguna sugerencia?
