How to create a fully customized Alert Dialog?

问题

Is there a solution to create an Alert Dialog with no borders around? If I create a layout and attach it to the Alert Dialog, I have my layout shown, but it's surrounded by the default dialog borders. Any way to cut them off? Thanks in advance.

Here is one way (if you don't like this particular example with the green border, scroll below to see a second one I found).

Here is another example (this one gives you an example without a border, and one with a border. The explanations are in Japanese, but the code is given for both.)

Hi if you use your own layout then set this in your styles.xml

<style name="Theme.Transparent_layout" parent="android:style/Theme.Dialog">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>

</style>

and set this style in your manifest file

<activity android:name=".Main" android:theme="@style/Theme.Transparent_layout" />
