android中的对话框之四：各种系统对话框的使用实例

http://blog.csdn.net/lamp_zy/article/details/7703908

1、新建工程：DialogTest

2、编写布局文件：

（1）、main.xml 代码如下：


View
Code

1 <?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
Code

1   <?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
Code

1 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;
  8 import android.app.Dialog;
  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;

 41         
 42         button01.setOnClickListener(new OnClickListener() {
 43             @Override

 53                 showDialog(dialog2);

 55         });
 56         
 57         button03.setOnClickListener(new OnClickListener() {
