如何显示的图像比手​​机屏幕尺寸更大？

我有没有找到一个真正的一致答案的问题。
这就是为什么我接触到你们。

I have a question that I didn't find a real consistent answer for. That is why I am reaching out to you guys.

我一直想实现我在下面的意义上应用程序中的取景器的效果：

I've been trying to achieve a 'viewfinder' effect for my application in the following sense:

我有，我希望能够飞过的巨幅照片（水平和放滚动;垂直，直到我到达边界）。到目前为止，所有流行的答案，这个（或类似的问题）是使用类似于这样的一个模式：

I have a huge picture that I want to be able to "fly" over (scroll horizontally & vertically until I reach the boundaries). So far, all the popular answers to this (or similar questions) is to use a schema that resembles something like this:

<ScrollView...>

  <RelativeLayout ...>

    <Imageview ...>
    </Imageview>

  </RelativeLayout>

</ScrollView>

这不适合我的工作，因为它的比例缩小的，我试图保持在原来的 BIG 的大小，这样我可以让用户浏览图像在它。

This does not work for me, because it scales down the picture that I'm trying to keep at the original BIG size so that I can let the user navigate over it.

我想我的问题归结为： 如何让谷歌地图滚动使用的是Android视图和布局的功能，如果可能的话...如果没有，你有建议吗？我应该前往更倾向于2D画布操作？ 的

I guess my question boils down to this: how to get the Google Maps scroll feature using Android Views and Layouts if at all possible... If not, do you have a suggestion? Should I head more towards 2D Canvas operations ?

感谢您。
