//设置SelectPicPopupWindow弹出窗口的宽

//实例化一个ColorDrawable颜色为半透明

//设置SelectPicPopupWindow弹出窗口的背景
this.setBackgroundDrawable(dw);
//mMenuView加入OnTouchListener监听推断获取触屏位置假设在选择框外面则销毁弹出框

new int[] { R.id.share_iv, R.id.share_txt,});
gridView.setNumColumns(3);
gridView.setAdapter(adapter);
gridView.setOnItemClickListener(listener);
}

}

//实现就可以

CustomPopupWindowView pop = new CustomPopupWindowView(NLPGActivity.this,new ItemClick());
//显示窗体
pop.showAtLocation(view,Gravity.BOTTOM|Gravity.CENTER_HORIZONTAL, 0, 0);
