使用意图单击上下文菜单将信息传递到另一个活动

Question

我正在尝试使用put extra将额外信息发送到用户单击上下文菜单时的其他活动。上下文菜单会加载活动，但信息不会显示在其他活动上。下面的代码显示了我的尝试。

    public void in(int position) {
        // gets the position of the item in my array list
        Cars c = cars.get(position);
        Intent i = new Intent(this, DisplayMessageActivity.class);

        i.putExtra("TITLE", c.getCarsTitle());
        startActivity(i);
    }

    // create context menu
    public void onCreateContextMenu(ContextMenu menu, View v,
            ContextMenuInfo menuInfo) {

        super.onCreateContextMenu(menu, v, menuInfo);
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.cars_menu_layout, menu);

    }

    // runs on long click
    public boolean onContextItemSelected(MenuItem item) {

        AdapterContextMenuInfo info = (AdapterContextMenuInfo) item
                .getMenuInfo();

        switch (item.getItemId()) {
        case R.id.register:

            // runs the method that starts the intent
            in(0);

            return true;
        case R.id.view:

            return true;
        default:
            return super.onContextItemSelected(item);
        }

    }

尝试使用

i.putExtra("TITLE", c.getCarsTitle().toString);
