scrollview 和 edittext 焦点冲突

ScrollView view = (ScrollView)findViewById(R.id.scrollView);
    view.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS);
    view.setFocusable(true);
    view.setFocusableInTouchMode(true);
    view.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            v.requestFocusFromTouch();
            return false;
        }
    });
