*/
protected void createPopupWindow(View parent) {

// 创建PopupWindow对象
final PopupWindow pop = new PopupWindow(view,
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT, true);

pop.setOutsideTouchable(true);  //设置点击窗口外边窗口消失
pop.setFocusable(true);  // 设置此参数获得焦点，否则无法点击
//		pop.setAnimationStyle(R.style.PopupAnimation);

if(pop.isShowing()){  //如果pop是有的
pop.dismiss();
}else{
//弹出框在组件之下

4. 将popupwindow放在屏幕中间
vi=(RelativeLayout)this.findViewById(R.id.maintainlayout); //主布局

pop.showAtLocation(vi, Gravity.CENTER, 0, 0);
