Android 点击其他地方键盘消失

在做项目中就遇到了这个问题，就是需要当点击页面其他部位时，输入键盘消失，当点击到EditTex时，不进行操作。下面是我的解决方案，实现Activity的dispatchTouchEvent方法，对事件进行触摸事件进行监听。

   @Override
    public boolean dispatchTouchEvent(MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            View v = getCurrentFocus();
            //如果点击除EditText以外的其他VIew，键盘回收
            if (v instanceof EditText) {
                View nextFocus = findViewFocus(contentView,event);
                if(nextFocus != null && nextFocus instanceof EditText){
                    return super.dispatchTouchEvent( event );
                }
                Rect outRect = new Rect();
                v.getGlobalVisibleRect(outRect);
                if (!outRect.contains((int)event.getRawX(), (int)event.getRawY())) {
                    //AndroidUtils.hideSoftKeyboard(this,contentView);
                    contentView.requestFocus();
                    v.clearFocus();
                }
            }
        }
        return super.dispatchTouchEvent( event );
    }

 private View findViewFocus(ViewGroup viewGroup,MotionEvent event){
        View view = null;
        int childCount = viewGroup.getChildCount();
        for(int i = 0;i< childCount ;i++ ){
            view = viewGroup.getChildAt(i);
            Rect outRect = new Rect();
            view.getGlobalVisibleRect(outRect);
            if (outRect.contains((int)event.getRawX(), (int)event.getRawY())) {
                if(view instanceof ViewGroup){
                    return findViewFocus((ViewGroup) view,event);
                } else {
                    return view;
                }
            }
        }
        return null;
    }
