Android Dialog的使用例子Demo

第一个XML,布局的

View Code

 1 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 2     xmlns:tools="http://schemas.android.com/tools"
 3     android:layout_width="match_parent"
 4     android:layout_height="match_parent"
 5     android:paddingBottom="@dimen/activity_vertical_margin"
 6     android:paddingLeft="@dimen/activity_horizontal_margin"
 7     android:paddingRight="@dimen/activity_horizontal_margin"
 8     android:paddingTop="@dimen/activity_vertical_margin"
 9     tools:context=".MainActivity" >
10     
11     <Button
12         android:id="@+id/MyButtonClick"        
13         android:text="普通按钮01"
14         android:layout_width="wrap_content"
15         android:layout_height="wrap_content"        
16         />
17     <Button
18         android:id="@+id/MyButtonClick02"        
19         android:text="文本按钮02"
20         android:layout_below="@id/MyButtonClick"
21         android:layout_width="wrap_content"
22         android:layout_height="wrap_content"            
23         />
24     <Button
25         android:id="@+id/MyButtonClick03"        
26         android:text="普通按钮03"
27         android:layout_below="@id/MyButtonClick02"
28         android:layout_width="wrap_content"
29         android:layout_height="wrap_content"            
30         />    
31     <Button
32         android:id="@+id/MyButtonClick04"        
33         android:text="普通按钮04"
34         android:layout_below="@id/MyButtonClick03"
35         android:layout_width="wrap_content"
36         android:layout_height="wrap_content"            
37         />            
38 </RelativeLayout>

第二个XML,实现第三个按钮的

View Code

 1 <?xml version="1.0" encoding="utf-8"?>
 2  <LinearLayout
 3    xmlns:android="http://schemas.android.com/apk/res/android"
 4    android:orientation="vertical"
 5    android:layout_width="fill_parent"
 6    android:layout_height="fill_parent">
 7      
 8      <TextView
 9        android:id="@+id/username_view"
10        android:layout_width="wrap_content"
11        android:layout_height="wrap_content"
12        android:layout_marginLeft="20dip"
13        android:layout_marginRight="20dip"
14        android:text="用户名"
15        android:textAppearance="@android:style/TextAppearance.Medium"
16      />
17      <EditText
18        android:id="@+id/username_edit"
19        android:layout_width="fill_parent"
20        android:layout_height="wrap_content"
21        android:layout_marginLeft="20dip"
22        android:layout_marginRight="20dip"
23        android:capitalize="none"
24        android:textAppearance="@android:style/TextAppearance.Medium"
25      />
26         <TextView
27        android:id="@+id/password_view"
28        android:layout_width="wrap_content"
29        android:layout_height="wrap_content"
30        android:layout_marginLeft="20dip"
31        android:layout_marginRight="20dip"
32        android:text="密码"
33        android:textAppearance="@android:style/TextAppearance.Medium"
34      />
35       <EditText
36        android:id="@+id/password_edit"
37        android:layout_width="fill_parent"
38        android:layout_height="wrap_content"
39        android:layout_marginLeft="20dip"
40        android:layout_marginRight="20dip"
41        android:capitalize="none"
42        android:password="true"
43        android:textAppearance="@android:style/TextAppearance.Medium"   
44      />
45  </LinearLayout>
