推荐答案

您只需要在对话框中创建一个自定义布局，然后手动关联了控制。这应该让你开始。

You just need to create a custom layout for the dialog then wire up the controls manually.. this should get you started.

customdialoglayout.xml

customdialoglayout.xml

<?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">

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="horizontal" android:layout_width="fill_parent"
        android:layout_height="fill_parent">

        <ImageView ... />
        <TextView android:text="Alert Info" ... />
    </LinearLayout>
    <!-- Additional Content Here -->
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="horizontal" android:layout_width="fill_parent"
        android:layout_height="fill_parent">

        <Button android:id="@+id/btnOkay" android:text="Ok" ...></Button>
        <Button android:id="@+id/btnCancel" android:text="Cancel" ...></Button>
    </LinearLayout>
</LinearLayout>

设置自定义布局的对话框初始化后..

Set the custom layout to the dialog after initializing..

dialog.setContentView(R.layout.customdialoglayout);

要连接你的处理器，你将不得不做一些事来的效果。

To wire up your handlers you will have to do something to the effect of..

Button myButton = (Button)dialog.findViewById(R.id.btnOkay);

我张贴只是截断作为一个例子中的XML，额外的自定义样式将需要获得所需的造型，当然更换所需的实际属性的省略号，但你可以看到你想要实现的目标是很简单。

The XML I posted is truncated just as an example, additional custom styling will be needed to achieve the desired look and of course replace the ellipses with the actual attributes that you want, but as you can see what you want to accomplish is fairly simple.
