displaying item on specific listview item only

I am trying to get a button to show up on my list item (declared as android:visibility:"gone" in the XML) to show as visible when I perform some gestures on it. However, how can I actually notify the getView method correctly to display the button only on the listview item?

I tried using getChildAt(position) which ended up displaying several buttons at once.

I tried passing in the position for example I detected that the gesture was performed on from pointToPosition and passed it into the adapter for the getView method to display, but it had the same pro开发者_如何学编程blem of displaying several at once.

do anyone know how can I solve this?

I think you may have a misunderstanding of how Adapter.getView() works its meant to create or reuse layouts when rendering the ListView it also needs to be fast so conditional manipulation in this method is discouraged. Although ListView.getChildAt() may work it does not effectively use the API. Your adapter will have a setViewBinder() unless you're using an ArrayAdapter (if so I suggest using SimpleAdapter because of the additional features). Use your ViewBinder implementation to switch the visibility of the button.

If you'd prefer to continue to use ArrayAdapter use ListView.getChildAt(int) to findViewById(R.id.your_button).setVisibility(). If this is what you already tried and its setting all the buttons visible then please post the related code.
