Prevent action on react native buttons while context menu is presented and support adding a title to Android context menu

[jefflewis]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-native-context-menu-view@1.15.0 for the project I'm working on.

Here is the diff that solved my problem:

This is really cool! Would you be up for opening a PR to add this in? Thanks in advance

I'm adding this to our own app, which will go through a thorough set of regression tests. Once that is all done and the patch is proven, I'll add a PR here with whatever we end up with.

I think everything is OK with this. I'm not doin null checking on the view, but my assumption is that the willEndForConfiguration will always be called if willDisplayMenuForConfiguration is called. If that isn't true, this would leave that garbage view in place forever.

For the android title, I'll split into a separate PR... mostly because the view doesn't expand to fit the title... I just put a bunch of spaces in the one spot where this affected my app, but it'd be better to get an actual fix in place.

@jefflewis The patch for prevention of action while context menu is appearing is not working on our side.

I'll ensure I add to the sample app to test this behavior. This so far has been working for us the past month in production.

We had a similar problem on Android not with a <Button> but with a <TouchableOpacity>; in our case, simply adding

onLongPress={() => {}}

to the enclosed <TouchableOpacity> would do the trick. Doing so, the onPress action stemming from the context menu is naturally ignored on the touchable opacity. I guess this could also work for a button.

I was wondering though why there is no Android code in your patch with regards to the "prevent action on buttons" part?
