调用方式

private void showPopup() {
        View view = LayoutInflater.from(this).inflate(R.layout.layout_insurance_list_pop_up,null);//PopupWindow对象
        listView = (ListView)view.findViewById(R.id.lv);
        View rootView  = (LinearLayout)view.findViewById(R.id.llt_root);
        listView.setAdapter(adapter);
        if (popupWindow != null){
            popupWindow = null;
        }

        //初始化PopupWindow对象
        popupWindow=new PopupWindow(view, ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.MATCH_PARENT);
        popupWindow.setOutsideTouchable(true);
        popupWindow.setFocusable(true);
        popupWindow.setBackgroundDrawable(new ColorDrawable());
        // 设置滑入滑出的动画效果
        popupWindow.setAnimationStyle(R.style.style_pop_up_window2);

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                SysBean bean = sysBeanList.get(i);
                if (bean != null){
                    tvInsurane.setText(!TextUtils.isEmpty(bean.name)?bean.name:"");
                }
                if (popupWindow != null && popupWindow.isShowing()){
                    popupWindow.dismiss();
                }
            }
        });


        //点击外面让popupwindow消失
        rootView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                if (popupWindow != null && popupWindow.isShowing()){
                    popupWindow.dismiss();
                }
                return false;
            }
        });

        //让popupwindow在底部显示
        popupWindow.showAtLocation(getWindow().getDecorView(), Gravity.BOTTOM, 0, 0);
    }
