推荐答案

不幸的是，这个问题没有内置函数（尚未无论如何），所以为了让它工作，你必须创建自己的自定义控制这个动作。这意味着捕捉触摸事件，并根据所述手势变焦。
要进入这个多一点细节，有超过地图画布上的控制，并在其中捕捉触摸事件。

Unfortunately there is no built-in function for this (not yet anyway), so in order to make it work you will have to create your own custom control for this action. This means capturing the touch event and zooming according to the gesture. To go into a little more details on this, have a control over the map canvas, and in it capture the touch events.

因为你正在为Android原生你的第二个选择是使用谷歌地图在Android（然而，这是Java的JavaScript不）。 http://mobiforge.com/developing：您可以在此发现这里的基础教程/剧情/使用，谷歌，地图，安卓

Your second option since you are building for Android native is to use google maps from android (however this is java not javascript). You can find a basic tutorial on this here: http://mobiforge.com/developing/story/using-google-maps-android
