The scenario is like the following: 1. MyView is one of the component in MyActivity. 2. MyActivity is created from other activity, with an intent containing all the information for the activity, including the parameter for MyView. 3. We shall pass the parameter to the constructor of MyView, for the construction of it.
I thought of other ways, like use the shared preference, it seems also work. But not a good way.
