安卓PopupWindow的使用

  //弹出showPopWindow
    public void showPopWindow() {
        
        View view = LayoutInflater.from(this).inflate(R.layout.main_set, null);
        
        view.findViewById(R.id.xfk_layout).getBackground().setAlpha(0);   //透明度
        
        TextView text1_kq = (TextView) view.findViewById(R.id.text1_kq_fregment);   //考勤签到

          //设置PopupWindow的显示大小
        final PopupWindow window = new PopupWindow(view, ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
     
        window.setFocusable(true);//设置popupwindow可以获取焦点
       
        //给pupupwindow设置一个背景 透明的,以便点击popupwindow外边时候可以实现消失
        window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
       
        window.setOutsideTouchable(true);//设置点击外部消失
       
        window.showAsDropDown(btn_fragment);//显示在按钮下方
       
        //window.showAtLocation(view, Gravity.RIGHT,0,0);或者显示在指定父布局上边的指定位置

        //考勤
        text1_kq.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                
                window.dismiss();
                
            }
        });
    }
