How to show another ContextMenu when I click an item of the first ContextMenu ?.

Its something like a questioner where you select answers from the ContextMenu items, depending on which next ContextMenu items must be Populated

How to show another ContextMenu when i click an Item of the 1st ContextMenu??

I don't know how deep you want the ContextMenu to be but for two levels you could have a boolean flag, to select between the two cases, which will be updated from onContextItemSelected :

boolean flag = true;

@Override
public void onCreateContextMenu(ContextMenu menu, View v,
        ContextMenu.ContextMenuInfo menuInfo) {
    if (flag) {
       menu.add("It's right");
       menu.add("It's wrong");
    } else {
       // the second menu
       menu.add("Ha Ha");
    }
}

Then in the onContexItemSelected callback simply update the flag and post a Runnable to show the ContextMenu again:

@Override
public boolean onContextItemSelected(MenuItem item) {
       if (item.getItemId() == theIdOfItemFromSecondContextMenu) {
        // do stuff
        return true;
    }
    // if you pass at this level, then you need to show the second ContextMenu
    flag = false;
    theView.post(new Runnable() {

        @Override
        public void run() {
            theView.showContextMenu();
        }
    });
    return true;
}

Anyway, I would advise against such code and simply use a custom Dialog (or a DialogFragment to have a backstack for the user to cycle through).
