在做项目中，dialog中是经常用的，今天介绍各种基本常用各种的dialog,基本满足你的需求。
dialog基本分为四种，但是今天只介绍AlertDialog和ProgressDialog：
1. 警告对话框 AlertDialog
2. 进度对话框 ProgressDialog
3. 日期选择对话框 DatePickerDialog
4. 时间选择对话框 TimePickerDialog
首先介绍下Dialog：
看完这个动态效果下面就是实现的方法：
MainActivity：
public class MainActivity extends Activity{ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } /**第一个*/ private void button1Onclick(View view) { new ActionSheetDialog(MainActivity.this) .builder() .setTitle("确定要清空消息列表？") .setCancelable(false)//dialog弹出后会点击屏幕或物理返回键，dialog不消失 .setCanceledOnTouchOutside(false)//dialog弹出后会点击屏幕，dialog不消失；点击物理返回键dialog消失 .addSheetItem("清空消息列表", SheetItemColor.Red, new OnSheetItemClickListener() { @Override public void onClick(int which) { } }).show(); } /**第二个*/ private void button2Onclick(View view) { new ActionSheetDialog(MainActivity.this) .builder() .setCancelable(false) .setCanceledOnTouchOutside(false) .addSheetItem("发送给好友", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("转载到空间相册", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("上传到群相册", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("保存到手机", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("收藏", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("查看聊天图片", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { } }).show(); } /**第三个*/ private void button3Onclick(View view) { new ActionSheetDialog(MainActivity.this) .builder() .setTitle("请选择操作") .setCancelable(false) .setCanceledOnTouchOutside(false) .addSheetItem("条目一", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { Toast.makeText(MainActivity.this, "item" + which, Toast.LENGTH_SHORT) .show(); } }) .addSheetItem("条目二", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { Toast.makeText(MainActivity.this, "item" + which, Toast.LENGTH_SHORT) .show(); } }) .addSheetItem("条目三", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { Toast.makeText(MainActivity.this, "item" + which, Toast.LENGTH_SHORT) .show(); } }) .addSheetItem("条目四", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { Toast.makeText(MainActivity.this, "item" + which, Toast.LENGTH_SHORT) .show(); } }) .addSheetItem("条目五", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { Toast.makeText(MainActivity.this, "item" + which, Toast.LENGTH_SHORT) .show(); } }) .addSheetItem("条目六", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { Toast.makeText(MainActivity.this, "item" + which, Toast.LENGTH_SHORT) .show(); } }) .addSheetItem("条目七", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { Toast.makeText(MainActivity.this, "item" + which, Toast.LENGTH_SHORT) .show(); } }) .addSheetItem("条目八", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { Toast.makeText(MainActivity.this, "item" + which, Toast.LENGTH_SHORT) .show(); } }) .addSheetItem("条目九", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { Toast.makeText(MainActivity.this, "item" + which, Toast.LENGTH_SHORT) .show(); } }) .addSheetItem("条目十", SheetItemColor.Blue, new OnSheetItemClickListener() { @Override public void onClick(int which) { Toast.makeText(MainActivity.this, "item" + which, Toast.LENGTH_SHORT) .show(); } }).show(); } /**第四个*/ private void button4Onclick(View view) { new AlertDialogTest(MainActivity.this).builder().setTitle("退出当前账号") .setMsg("再连续登陆15天，就可变身为QQ达人。退出QQ可能会使你现有记录归零，确定退出？") .setPositiveButton("确认退出", new OnClickListener() { @Override public void onClick(View v) { } }).setNegativeButton("取消", new OnClickListener() { @Override public void onClick(View v) { } }).show(); } /**第五个*/ private void button5Onclick(View view) { new AlertDialogTest(MainActivity.this).builder() .setMsg("你现在无法接收到新消息提醒。请到系统-设置-通知中开启消息提醒") .setCancelable(false) .setNegativeButton("确定", new OnClickListener() { @Override public void onClick(View v) { } }).show(); }}ActionSheetDialog：
