如何在本机C ++代码下使用android UI控件

Question

THE QUESTION is how to reuse the android text edit control, which is java, in our software (C++).

Here is some background:

My company's gps software is written in c++ (agg for ui rendering), it can run under iOS, Android and WinCE/Windows. But for now our main focus is android.

Now we need a text edit UI element, we are considering using android ui elements instead of reinventing it ourselves.

Thanks.

You cannot directly use GUI elements which are part of the SDK in the NDK. You can use OpenGL to draw whatever you need if you need an all c++ app.

You can, however, build a sdk based UI layer on top of your app and use JNI to call your underlying c code. Check out this tutorial for a sample:
