在android中子碎片的edittext中移除焦点后，软键盘不会消失

InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);

View view = getView();
if (view != null) {
    view.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
            return false;
        }
    });
}

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    if (ev.getAction() == MotionEvent.ACTION_DOWN) {
        View view = getCurrentFocus();
        if (view instanceof EditText) {
            Rect outRect = new Rect();
            view.getGlobalVisibleRect(outRect);
            if (!outRect.contains((int) ev.getRawX(), (int) ev.getRawY())) {
                view.clearFocus();
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
            }
        }
    }
    return super.dispatchTouchEvent(ev);
