EditText에서 작동하도록 스 와이프 제스처를 시도하고 있습니다. 그러나 내가 시도하는 모든 것은 버그가있는 경향이 있습니다.edittext에서 Android 핸들링 스 와이프 제스처
false를 반환하면 제스처가 작동하지만 스 와이프 제스처를 만들 때 커서가 움직입니다. 그러나 GestureListener (onFling)에서 결과를 반환하면 커서 체재가 유지되지만 Android 2.3.3에서는 제스처가 끝난 후 텍스트 편집의 상황에 맞는 메뉴가 팝업됩니다 (4.1.2에서는 컨텍스트 메뉴가 없음) 그러나 제스처를 만드는 것은 전체 단어를 선택할 것입니다.
