分享一个Android中Dialog的使用例子

1、新建工程：DialogTest

2、编写布局文件：

（1）、main.xml   代码如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="vertical"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     > <TextView      android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:text="@string/hello"     />     <Button        android:id="@+id/button01"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/button01"     />      <Button        android:id="@+id/button02"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/button02"     />      <Button        android:id="@+id/button03"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/button03"     />      <Button        android:id="@+id/button04"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/button04"     /> </LinearLayout>

（2）alert_dialog_text_entry.xml   此部分布局是实现可以用户交互的。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45

<?xml version="1.0" encoding="utf-8"?> <LinearLayout   xmlns:android="http://schemas.android.com/apk/res/android"   android:orientation="vertical"   android:layout_width="fill_parent"   android:layout_height="fill_parent">           <TextView       android:id="@+id/username_view"       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:layout_marginLeft="20dip"       android:layout_marginRight="20dip"       android:text="用户名"       android:textAppearance="@android:style/TextAppearance.Medium"     />     <EditText       android:id="@+id/username_edit"       android:layout_width="fill_parent"       android:layout_height="wrap_content"       android:layout_marginLeft="20dip"       android:layout_marginRight="20dip"       android:capitalize="none"       android:textAppearance="@android:style/TextAppearance.Medium"     />        <TextView       android:id="@+id/password_view"       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:layout_marginLeft="20dip"       android:layout_marginRight="20dip"       android:text="密码"       android:textAppearance="@android:style/TextAppearance.Medium"     />      <EditText       android:id="@+id/password_edit"       android:layout_width="fill_parent"       android:layout_height="wrap_content"       android:layout_marginLeft="20dip"       android:layout_marginRight="20dip"       android:capitalize="none"       android:password="true"       android:textAppearance="@android:style/TextAppearance.Medium"       /> </LinearLayout>

3、编写资源文件：strings.xml

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

<?xml version="1.0" encoding="utf-8"?> <resources>     <string name="hello">对话框</string>     <string name="app_name">Android Dialog</string>     <string name="button01">两个button的对话框</string>     <string name="button02">三个button的对话框</string>     <string name="button03">可以进行输入的对话框</string>     <string name="button04">进度框</string>     <string name="alert_dialog_two_buttons_title">这是一个提示框，点击取消后可以返回。</string>     <string name="alert_dialog_ok">确定</string>     <string name="alert_dialog_cancle">取消</string>     <string name="alert_dialog_three_buttons_title">标题部分</string>     <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。     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        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>        <string name="alert_dialog_something">进入详细</string>        <string name="alert_diaog_text_entry">请输入</string> </resources>

4、开发主逻辑代码：DialogTest.java

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180
