Ok everyone knows that to hide a keyboard you need to implement:
InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
imm.hi
Just Add this code in the class @Overide
public boolean dispatchTouchEvent(MotionEvent ev) {
View view = getCurrentFocus();
if (view != null && (ev.getAction() == MotionEvent.ACTION_UP || ev.getAction() == MotionEvent.ACTION_MOVE) && view instanceof EditText && !view.getClass().getName().startsWith("android.webkit.")) {
int scrcoords[] = new int[2];
view.getLocationOnScreen(scrcoords);
float x = ev.getRawX() + view.getLeft() - scrcoords[0];
float y = ev.getRawY() + view.getTop() - scrcoords[1];
if (x < view.getLeft() || x > view.getRight() || y < view.getTop() || y > view.getBottom())
((InputMethodManager)this.getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow((this.getWindow().getDecorView().getApplicationWindowToken()), 0);
}
return super.dispatchTouchEvent(ev);
}
