如何使对象可识别为不同的活动？

Question

我的活动中有一个名为ship1的对象。 ship1有一个名为addSpend的值。 以下

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.hangar);

    final Ship ship1 = new Ship();
    ship1.setAddTime(1000);
    ship1.setAddAmount(1);
    ship1.setAddSpend(5);

我还有另一个活动，它有一个字符串array.Below

 HangarActivity hAObject= new HangarActivity();
    int ship1AddSpend = hAObject.ship1.getAddSpend();


            final String[] shipDesc = {
                    "10 Planets Every 5 Secs \n" + ship1AddSpend + "$",
                    "50 Planets Every 5 Secs \n",
                    "100 Planets Every 5 Secs \n 1500$",
                    "500 Planets Every 4 Secs \n 3000$",
                    "1000 Planets Every 4 Secs \n 7500$",
                    "5000 Planets Every 4 Secs \n 15000$",
                    "10000 Planets Every 3 Secs \n 50000$",
                    "30000 Planets Every 3 Secs \n 100000$",
                    "60000 Planets Every 3 Secs \n  500000$",
                    "100000 Planets Every 1 Secs \n 1000000$"};

在第二个活动中，您可以看到我有一个名为ship1AddSpend的整数，它是ship1s addSpend的值。问题是整数不能找到ship1所以在android studio ship1中在第二个活动中出现红色。那么我如何让ship1可以识别第二个活动呢？
