  //加载布局

                                  ViewcontentView=View.inflate(getApplicationContext(), R.layout.popu_dialog, null);

                                  LinearLayoutll_call=(LinearLayout)contentView.findViewById(R.id.ll_call);

                                  LinearLayoutll_sms=(LinearLayout) contentView.findViewById(R.id.ll_sms);

                                  //弹出popu对话框

                                  pw=newPopupWindow(contentView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

                                  //背景透明

                                  pw.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

                                  //宽,高的数组

                                  int[] location=newint[2];

                                  view.getLocationInWindow(location);

                                  pw.showAtLocation(view,Gravity.LEFT|Gravity.TOP,30, location[1]);
