此例子源于网络，下载下来之后，自己加了写注释，作为总结，发到博客中，谢谢原作者
通过这个例子学到的东西
1.自定义对话框的使用
2.程序中使用颜色如何进行存放，增加复用性
3.加深线性布局、常用控件的使用
1.实现效果
2.颜色值文件
<?xml version="1.0" encoding="utf-8"?>
<resources>
<drawable name="white">#FFFFFF</drawable>
<color name="White">#FFFFFF</color>
<color name="Black">#000000</color>
<color name="grey">#D7D4D4</color>
<color name="red">#FF0000</color> </resources>
3.第一个界面布局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|center_vertical"
android:orientation="vertical"> <LinearLayout
android:orientation="vertical"
android:background="@drawable/alert"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:layout_marginLeft="20dip"
android:layout_marginRight="20dip"> <TextView android:id="@+id/dialog_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="15dip"
android:textColor="#ffffff"
android:textStyle="bold"
android:textSize="17sp"
android:text="About to call 323"/> <TextView android:id="@+id/dialog_message"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dip"
android:gravity="center_horizontal"
android:textSize="15sp"
android:textColor="#ffffff"
android:text="Are you sure you want to proceed?" /> <Button
android:id="@+id/ok"
android:layout_width="fill_parent"
android:layout_height="40dip"
android:layout_marginBottom="10dip"
android:layout_marginLeft="10dip"
android:layout_marginRight="10dip"
android:background="@drawable/custom_button"
android:textColor="@color/White"
android:textSize="17sp"
android:textStyle="bold"
android:text="OK"/>
</LinearLayout>
</LinearLayout>
4.第二个界面的布局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|center_vertical"
android:orientation="vertical"> <LinearLayout
android:orientation="vertical"
android:background="@drawable/alert"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:layout_marginLeft="20dip"
android:layout_marginRight="20dip"> <TextView android:id="@+id/dialog_title_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="15dip"
android:textColor="#ffffff"
android:textStyle="bold"
android:textSize="17sp"
android:text="About to call 323"/> <TextView android:id="@+id/dialog_message_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dip"
android:gravity="center_horizontal"
android:textSize="15sp"
android:textColor="#ffffff"
android:text="Are you sure you want to proceed?" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dip"
android:layout_marginTop="10dip"
android:gravity="center_horizontal"
android:orientation="horizontal" > <Button
android:id="@+id/cancel_2"
android:layout_width="0dip"
android:layout_height="40dip"
android:layout_gravity="left"
android:layout_marginLeft="10dip"
android:layout_weight="1"
android:background="@drawable/custom_button"
android:text="取消"
android:textColor="@color/White"
android:textStyle="bold" /> <Button
android:id="@+id/ok_2"
android:layout_width="0dip"
android:layout_height="40dip"
android:layout_marginBottom="10dip"
android:layout_marginRight="10dip"
android:layout_weight="1"
android:background="@drawable/custom_button"
android:text="确定"
android:textColor="@color/White"
android:textStyle="bold" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
