android-如何关闭AlertDialog.Builder对话框

前言
在实际写代码的时候，AlertDialog.Builder的使用算是比较频繁的，在对AlertDialog.Builder关闭的时候，我们会发现，AlertDialog.Builder对话框没有相对应的finish()或者dismiss()这样的方法可使用。

那么我们在关闭的时候怎么才能做到呢？

##AlertDialog
父类AlertDialog有dismiss方法，可以实现对话框的关闭，而且AlertDialog.Builder在.show()的时候会得到一个AlertDialog对象，用dismiss方法将该Builder关闭。

##自定义的AlertDialog.Builder布局示例
这里写图片描述

/*** 设置dialog的出现* @param hangTag*/private void showCustomizeDialog(HangTag hangTag) {final AlertDialog.Builder customizeDialog = new AlertDialog.Builder(getActivity());customizeDialog.setCancelable(false);View infoview = LayoutInflater.from(getActivity()).inflate(R.layout.wr_dialog_hangtag_info,null, false);TextView exchangeName, volume, marketPirce, region, irrigation, administrative, watertype,exchangeTime;Button backColse;exchangeTime = (TextView) infoview.findViewById(R.id.exchange_time);exchangeName = (TextView) infoview.findViewById(R.id.exchangeName);volume = (TextView) infoview.findViewById(R.id.volume);marketPirce = (TextView) infoview.findViewById(R.id.marketPirce);region = (TextView) infoview.findViewById(R.id.region);irrigation = (TextView) infoview.findViewById(R.id.irrigation);administrative = (TextView) infoview.findViewById(R.id.administrative);watertype = (TextView) infoview.findViewById(R.id.watertype);backColse = (Button) infoview.findViewById(R.id.back_colse);exchangeTime.setText(hangTag.getGprq()+"");exchangeName.setText(hangTag.getName());volume.setText(hangTag.getSl() + "");marketPirce.setText(hangTag.getJg() + "");region.setText(hangTag.getSzdq());irrigation.setText(hangTag.getSzgq());administrative.setText(hangTag.getSzglq());if (hangTag.getWaterType() == 8101) {watertype.setText("地下水");} else if (hangTag.getWaterType() == 8100) {watertype.setText("地表水");}customizeDialog.setView(infoview);final AlertDialog dialog = customizeDialog.show();/*** 返回*/backColse.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {dialog.dismiss();}});}

以上就是全部内容，仅做笔记，不喜勿喷！
