1、新建工程：DialogTest
2、编写布局文件：
（1）、main.xml 代码如下：
View Code1 <?xml version="1.0" encoding="utf-8"?>
2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
3 android:orientation="vertical"
4 android:layout_width="fill_parent"
5 android:layout_height="fill_parent"
6 >
7 <TextView
8 android:layout_width="fill_parent"
9 android:layout_height="wrap_content"
10 android:text="@string/hello"
11 />
12 <Button
13 android:id="@+id/button01"
14 android:layout_width="fill_parent"
15 android:layout_height="wrap_content"
16 android:text="@string/button01"
17 />
18 <Button
19 android:id="@+id/button02"
20 android:layout_width="fill_parent"
21 android:layout_height="wrap_content"
22 android:text="@string/button02"
23 />
24 <Button
25 android:id="@+id/button03"
26 android:layout_width="fill_parent"
27 android:layout_height="wrap_content"
28 android:text="@string/button03"
29 />
30 <Button
31 android:id="@+id/button04"
32 android:layout_width="fill_parent"
33 android:layout_height="wrap_content"
34 android:text="@string/button04"
35 />
36 </LinearLayout>
37
38 （2）alert_dialog_text_entry.xml 此部分布局是实现可以用户交互的。
39
40 <?xml version="1.0" encoding="utf-8"?>
41 <LinearLayout
42 xmlns:android="http://schemas.android.com/apk/res/android"
43 android:orientation="vertical"
44 android:layout_width="fill_parent"
45 android:layout_height="fill_parent">
46
47 <TextView
48 android:id="@+id/username_view"
49 android:layout_width="wrap_content"
50 android:layout_height="wrap_content"
51 android:layout_marginLeft="20dip"
52 android:layout_marginRight="20dip"
53 android:text="用户名"
54 android:textAppearance="@android:style/TextAppearance.Medium"
55 />
56 <EditText
57 android:id="@+id/username_edit"
58 android:layout_width="fill_parent"
59 android:layout_height="wrap_content"
60 android:layout_marginLeft="20dip"
61 android:layout_marginRight="20dip"
62 android:capitalize="none"
63 android:textAppearance="@android:style/TextAppearance.Medium"
64 />
65 <TextView
66 android:id="@+id/password_view"
67 android:layout_width="wrap_content"
68 android:layout_height="wrap_content"
69 android:layout_marginLeft="20dip"
70 android:layout_marginRight="20dip"
71 android:text="密码"
72 android:textAppearance="@android:style/TextAppearance.Medium"
73 />
74 <EditText
75 android:id="@+id/password_edit"
76 android:layout_width="fill_parent"
77 android:layout_height="wrap_content"
78 android:layout_marginLeft="20dip"
79 android:layout_marginRight="20dip"
80 android:capitalize="none"
81 android:password="true"
82 android:textAppearance="@android:style/TextAppearance.Medium"
83 />
84 </LinearLayout>
3、编写资源文件：strings.xml
View Code1 <?xml version="1.0" encoding="utf-8"?>
2 <resources>
3 <string name="hello">对话框</string>
4 <string name="app_name">Android Dialog</string>
5 <string name="button01">两个button的对话框</string>
6 <string name="button02">三个button的对话框</string>
7 <string name="button03">可以进行输入的对话框</string>
8 <string name="button04">进度框</string>
9 <string name="alert_dialog_two_buttons_title">这是一个提示框，点击取消后可以返回。</string>
10 <string name="alert_dialog_ok">确定</string>
11 <string name="alert_dialog_cancle">取消</string>
12 <string name="alert_dialog_three_buttons_title">标题部分</string>
13 <string name="alert_dialog_three_buttons_msg">对于程序员或创业团队来说，还是有必要拥有一个属于自己的博客。
14 Wordpress 曾经让个人或企业搭建博客变得非常容易。但是我们觉得 Wordpress
15 还是有些重量级，所以选择了一个非常轻便的工具 toto，一段只有200多行代码的Ruby应用程序。</string>
16 <string name="alert_dialog_something">进入详细</string>
17 <string name="alert_diaog_text_entry">请输入</string>
18 </resources>
4、开发主逻辑代码：DialogTest.java
View Code1 package com.dialogTest;
2
3 import com.listeview.R;
4
5 import android.app.Activity;
6 import android.app.AlertDialog;
7 import android.app.DatePickerDialog;

9 import android.app.ProgressDialog;
10 import android.app.TimePickerDialog;
11 import android.app.AlertDialog.Builder;
12 import android.content.Context;
13 import android.content.DialogInterface;
14 import android.os.Bundle;
15 import android.text.method.CharacterPickerDialog;
16 import android.view.LayoutInflater;
17 import android.view.View;
18 import android.view.View.OnClickListener;
19 import android.widget.Button;
20
21 public class DialogTest extends Activity {
22 private static final int dialog4 = 4;
23 private static final int dialog3 = 3;
24 private static final int dialog2 = 2;
25 private static final int dialog1 = 1;
26 /** Called when the activity is first created. */
27 private Button button01;
28 private Button button02;
29 private Button button03;
30 private Button button04;
31
32 @Override
33 public void onCreate(Bundle savedInstanceState) {

35 setContentView(R.layout.main);
36
37 button01=(Button)findViewById(R.id.button01);
38 button02=(Button)findViewById(R.id.button02);
39 button03=(Button)findViewById(R.id.button03);
40 button04=(Button)findViewById(R.id.button04);
41
42 button01.setOnClickListener(new OnClickListener() {
43 @Override
44 public void onClick(View v) {
45 showDialog(dialog1);
46 }
47 });
48
49 button02.setOnClickListener(new OnClickListener() {
50 @Override
51 public void onClick(View v) {
52 // TODO Auto-generated method stub
53 showDialog(dialog2);
54 }
55 });
56
57 button03.setOnClickListener(new OnClickListener() {

86 }
87 return null;
88 }
89 private Dialog buildDialog4(Context context) {
90 ProgressDialog dialog=new ProgressDialog(context);
91 dialog.setTitle("正在下载歌曲");
92 dialog.setMessage("请稍候......");
93

102 private Dialog buildDialog3(Context context) {
103 LayoutInflater inflater=LayoutInflater.from(this);
104 final View textEntryView=inflater.inflate(R.layout.alert_dialog_text_entry, null);
105
106 AlertDialog.Builder builder=new AlertDialog.Builder(context);
107 builder.setTitle(R.string.alert_diaog_text_entry);
108
109 builder.setView(textEntryView); //关键
110 builder.setPositiveButton(R.string.alert_dialog_ok, new DialogInterface.OnClickListener() {
