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 
/**
* 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() {
@Override
public void onClick(View view) {
dialog.dismiss();
}
});
}
以上就是全部内容，仅做笔记，不喜勿喷！
