android 对话框显示工具类

这个工具类非常简单，但是将显示dialog的方法统一封装，能够大大减少代码重复

package com.ctbri.weather.utils;



import android.app.AlertDialog;

import android.app.Dialog;

import android.app.ProgressDialog;

import android.content.Context;



public class ShowDialogActivity{



    public static void showDialog(Context con){

        Dialog dialog = new AlertDialog.Builder(con)

        .setTitle("����")

        .setMessage("�������,��������������")

        .setPositiveButton("ȷ��", null).create();

        dialog.show();

    }



    public static ProgressDialog showPgDialog(Context con,String msg){

        ProgressDialog pd = new ProgressDialog(con);

        pd.setMessage(msg);

        return pd;

    }

    public static void dialog(Context con,String title,String msg){

        Dialog dialog = new AlertDialog.Builder(con)

        .setTitle(title)

        .setMessage(msg)

        .setPositiveButton("ȷ��", null).create();

        dialog.show();

    }

    

}
