1 在实际开放中，有类似如下的效果

的实现思路有2种
一种是 实用popupWindow 来实现，一种是实用 fragment
对于第一种方案的代码主要如下：

 HotelIconPopUpWindow popUpWindow = new HotelIconPopUpWindow(mFragment.getActivity(), mItemModelList);    popUpWindow.setAnchorView(mFragment.getActivity().getWindow().getDecorView());
popUpWindow.showPopWindow();

这里我们将我门浮层的anchorView 设置为decorView

public class HotelIconPopUpWindow extends PopupWindow implements View.OnClickListener {

    private View mDialogView;
    private View mDropDownAnchorView;
    private Context mContext;
    private LinearLayout mIconContainer;
    private TextView mCloseIconTv;
    private ArrayList<IconItemModel> mItemIDList;

    public HotelIconPopUpWindow(Context context, ArrayList<IconItemModel> itemIDList) {
        mContext = context;
        mItemIDList = itemIDList;
        setContentView(createContentView());
        setWidth(ViewGroup.LayoutParams.MATCH_PARENT);
        setBackgroundDrawable(new ColorDrawable(Color.parseColor("#B3000000")));
        setOutsideTouchable(true);
        setFocusable(true);
    }

    public void setAnchorView(View anchor) {
        mDropDownAnchorView = anchor;
    }

    private int getMarginValue() {
        int screenHeight = DeviceUtil.getScreenHeight();
        return Math.round(screenHeight * 0.38f);
    }

    private View createContentView() {
        ViewGroup contentView = new FrameLayout(mContext);
        contentView.setFocusable(true);
        contentView.setFocusableInTouchMode(true);
        mDialogView = LayoutInflater.from(mContext).inflate(R.layout.hotel_detail_icon_info_popupwindow_layout, null);
        mIconContainer = (LinearLayout) mDialogView.findViewById(R.id.icon_container);
        mCloseIconTv = (TextView) mDialogView.findViewById(R.id.close);
        mCloseIconTv.setOnClickListener(this);
        contentView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
        FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.WRAP_CONTENT);
        lp.gravity = Gravity.BOTTOM;
        contentView.addView(mDialogView, lp);
        int padding = getMarginValue();
        contentView.setPadding(0, padding, 0, 0);
        return contentView;
    }

    public void showPopWindow() {
        if (mDropDownAnchorView == null || mDropDownAnchorView.getWindowToken() == null) return;
        setWidth(ViewGroup.LayoutParams.MATCH_PARENT);
        setHeight(ViewGroup.LayoutParams.MATCH_PARENT);
 setWindowLayoutMode(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        showAtLocation(mDropDownAnchorView, Gravity.BOTTOM, 0, 0);
        mDialogView.setFocusable(true);
        mDialogView.setFocusableInTouchMode(true);
        loadAnimation(mDialogView, R.anim.common_hotel_popwindow_in, false);
    }

    @Override
    public void dismiss() {
        loadAnimation(mDialogView, R.anim.common_hotel_popwindow_out, true);
    }

    private void loadAnimation(View view, int resId, boolean isSetListener) {
        Animation animation = AnimationUtils.loadAnimation(mContext, resId);
        animation.setFillAfter(true);
        if (isSetListener) {
            animation.setAnimationListener(new EndAnimationListener());
        }
        view.startAnimation(animation);
    }

    @Override
    public void onClick(View v) {
        int id = v.getId();
        if (id == R.id.close) {
            dismiss();
        }
    }

    private class EndAnimationListener implements Animation.AnimationListener {

        @Override
        public void onAnimationEnd(Animation animation) {
            new Handler().post(new Runnable() {
                @Override
                public void run() {
                    if (isShowing()) {
                 HotelIconPopUpWindow.super.dismiss();
                    }
                }
            });
        }
        @Override
        public void onAnimationRepeat(Animation animation) {
        }
        @Override
        public void onAnimationStart(Animation animation) {

        }
    }
}

这里要注意的是，首先我门要给popUpWindow 设置背景，

  setBackgroundDrawable(new ColorDrawable(Color.parseColor("#B3000000")));
  setOutsideTouchable(true);
  setFocusable(true);

这里我们在弹起的时候会有相应的背景，注意这个背景一定要设置，如果不设置，点击背景的区域的点击消失的功能，将消失， setOutsideTouchable(true); 控制window 内容区域外的部分点击自动消失。
同时注意设置背景的宽高

setWidth(ViewGroup.LayoutParams.MATCH_PARENT);
        setHeight(ViewGroup.LayoutParams.MATCH_PARENT);
 setWindowLayoutMode(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

第二种方案，即是实用fragment

 Bundle arguments = new Bundle();
   arguments.putBoolean("isOversea",cacheBean.isOversea());
        HotelFloatFacilitysFragment hotelFloatFacilitysFragment = new HotelFloatFacilitysFragment();
        if(cacheBean.isOversea()){  hotelFloatFacilitysFragment.setOverseaContent(cacheBean.getHotelOverseaFloatFacilityTags());
        }else{      hotelFloatFacilitysFragment.setInlandContent(cacheBean.getHotelInlandFloatFacilityTags());
        }      hotelFloatFacilitysFragment.setTargetFragment(mFragment,0);
     hotelFloatFacilitysFragment.setArguments(arguments);
        FragmentManager fragmentManager = mFragment.getFragmentManager();
        FragmentTransaction transaction = fragmentManager.beginTransaction(); transaction.setCustomAnimations(R.anim.common_hotel_popwindow_in_3,
                R.anim.common_hotel_popwindow_out_3,
                R.anim.common_hotel_popwindow_in_3,
                R.anim.common_hotel_popwindow_out_3);
        transaction.add(android.R.id.content,hotelFloatFacilitysFragment,"HotelFloatFacilitysFragment")  .addToBackStack("HotelFloatFacilitysFragment").commitAllowingStateLoss();
