Android Dialog的使用例子Demo

第一个XML,布局的

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >
    
    <Button
        android:id="@+id/MyButtonClick"        
        android:text="普通按钮01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"        
        />
    <Button
        android:id="@+id/MyButtonClick02"        
        android:text="文本按钮02"
        android:layout_below="@id/MyButtonClick"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"            
        />
    <Button
        android:id="@+id/MyButtonClick03"        
        android:text="普通按钮03"
        android:layout_below="@id/MyButtonClick02"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"            
        />    
    <Button
        android:id="@+id/MyButtonClick04"        
        android:text="普通按钮04"
        android:layout_below="@id/MyButtonClick03"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"            
        />            
</RelativeLayout>

第二个XML,实现第三个按钮的

<?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>
