很多时候，我们需要自己去定义dialog，目前我们就遇见了这样一个需求，我的想法是自己定义一个dialog，如果有list的话就使用listview，如果有msg的话就使用msg，并且取消和确定按钮也可自己定义。自定义一个dialog，好处是我们自己定义背景，自己定义事件，自己定义按钮，能很完美的达到自己想要的效果。
public class CustomDialog extends Dialog {//实现默认构造函数public CustomDialog(Context context, int theme) {    super(context, theme);    // TODO Auto-generated constructor stub}protected CustomDialog(Context context, boolean cancelable,        OnCancelListener cancelListener) {    super(context, cancelable, cancelListener);    // TODO Auto-generated constructor stub}public CustomDialog(Context context) {    super(context);    // TODO Auto-generated constructor stub}//所有的方法执行完都会返回一个Builder使得后面可以直接create和show public static class Builder {        private Context context;        private String title;        private String message;        private String positiveButtonText;//确定按钮        private String negativeButtonText;//取消按钮        private View contentView;        private BaseAdapter adapter;//listview的adapter        //确定按钮事件        private DialogInterface.OnClickListener positiveButtonClickListener;        //取消按钮事件        private DialogInterface.OnClickListener negativeButtonClickListener;        //listview的item点击事件        private AdapterView.OnItemClickListener listViewOnclickListener;       public Builder(Context context) {            this.context = context;        }        //设置消息        public Builder setMessage(String message) {            this.message = message;            return this;        }        /**         *设置内容         *          * @param title         * @return         */        public Builder setMessage(int message) {            this.message = (String) context.getText(message);            return this;        }        /**         * 设置标题         *          * @param title         * @return         */        public Builder setTitle(int title) {            this.title = (String) context.getText(title);            return this;        }        /**         *设置标题         *          * @param title         * @return         */        public Builder setTitle(String title) {            this.title = title;            return this;        }        //设置适配器        public Builder setAdapter(BaseAdapter adapter) {            this.adapter = adapter;            return this;        }        //设置点击事件        public Builder setOnClickListener(AdapterView.OnItemClickListener listViewOnclickListener) {            this.listViewOnclickListener = listViewOnclickListener;            return this;        }        //设置整个背景        public Builder setContentView(View v) {            this.contentView = v;            return this;        }        /**         * 设置确定按钮和其点击事件         *          * @param positiveButtonText         * @return         */        public Builder setPositiveButton(int positiveButtonText,                DialogInterface.OnClickListener listener) {            this.positiveButtonText = (String) context                    .getText(positiveButtonText);            this.positiveButtonClickListener = listener;            return this;        }        public Builder setPositiveButton(String positiveButtonText,                DialogInterface.OnClickListener listener) {            this.positiveButtonText = positiveButtonText;            this.positiveButtonClickListener = listener;            return this;        }        //设置取消按钮和其事件        public Builder setNegativeButton(int negativeButtonText,                DialogInterface.OnClickListener listener) {            this.negativeButtonText = (String) context                    .getText(negativeButtonText);            this.negativeButtonClickListener = listener;            return this;        }        public Builder setNegativeButton(String negativeButtonText,                DialogInterface.OnClickListener listener) {            this.negativeButtonText = negativeButtonText;            this.negativeButtonClickListener = listener;            return this;        }    //createview方法        public CustomDialog create() {            LayoutInflater inflater = (LayoutInflater) context                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
