java.lang.Throwable:ListView中带有SimpleDapter的addInArray

我有一个带有SimpleAdapter的ListView活动

活动：

public class TankListActivity extends FragmentActivity implements OnShowResult {

    private final String ATTRIBUTE_NUMBER = "Number";
    private final String ATTRIBUTE_FUEL = "Fuel";
    private final String ATTRIBUTE_CAPACITY = "Capacity";
    private final String ATTRIBUTE_CAPACITY_CURRENT = "Capacity Current";


    private SimpleAdapter adapter;
    private ArrayList<Map<String, Object>> tankList;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tank_list);

        tankList = new ArrayList<>();

        String[] from = {ATTRIBUTE_NUMBER, ATTRIBUTE_FUEL, ATTRIBUTE_CAPACITY_CURRENT, ATTRIBUTE_CAPACITY};
        int[] to = {R.id.textview_tankitem_number, R.id.textview_tankitem_fuel, R.id.textview_tankitem_capacity_current, R.id.textview_tankitem_capacity};
        adapter = new SimpleAdapter(getApplicationContext(), tankList, R.layout.tank_list_item, from, to);
        adapter.setViewBinder(new TankItemBinder());

        ListView list = (ListView)findViewById(R.id.listview_tanklistactivity_list);
        list.setAdapter(adapter);
        list.setOnScrollListener(scrollListener);
        list.setOnItemClickListener(onItemClickListener);
        registerForContextMenu(list);
    }

    // ...

    class TankItemBinder implements SimpleAdapter.ViewBinder {
    @Override
    public boolean setViewValue(View view, Object o, String s) {
        switch (view.getId()) {
            case R.id.textview_tankitem_number:
                int i = (int)o;
                ((TextView)view).setText("№" + ((i < 0)?"":i));
                return true;

            case R.id.textview_tankitem_fuel:
                ((TextView)view).setText((String)o);
                return true;

            case R.id.textview_tankitem_capacity:
                ((TextView)view).setText(o + " л");
                return true;

            case R.id.textview_tankitem_capacity_current:
                ((TextView)view).setText(o + " л");
                return true;

            default: return false;
        }
    }
}

}

到目前为止，我注意到：如果在创建SimpleAdapter之前，

tankList

被某个值初始化，则不会出现以下消息：

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tank_list);

    tankList = new ArrayList<>();

    // this solve the problem:
    Map<String, Object> item = new HashMap<>();
    item.put(ATTRIBUTE_NUMBER, -1);
    item.put(ATTRIBUTE_FUEL, "Loading...");
    item.put(ATTRIBUTE_CAPACITY_CURRENT, 0);
    item.put(ATTRIBUTE_CAPACITY, 0);
    tankList.add(item);


    String[] from = {ATTRIBUTE_NUMBER, ATTRIBUTE_FUEL, ATTRIBUTE_CAPACITY_CURRENT, ATTRIBUTE_CAPACITY};
    int[] to = {R.id.textview_tankitem_number, R.id.textview_tankitem_fuel, R.id.textview_tankitem_capacity_current, R.id.textview_tankitem_capacity};
    adapter = new SimpleAdapter(getApplicationContext(), tankList, R.layout.tank_list_item, from, to);
    adapter.setViewBinder(new TankItemBinder());

    ListView list = (ListView)findViewById(R.id.listview_tanklistactivity_list);
    list.setAdapter(adapter);
    list.setOnScrollListener(scrollListener);
    list.setOnItemClickListener(onItemClickListener);
    registerForContextMenu(list);
}

@覆盖
创建时受保护的void（@Nullable Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（右布局、储罐清单）；
tankList=新的ArrayList（）；
//这就解决了问题：
Map item=newhashmap（）；
物品放置（属性编号，-1）；
物品放置（属性“装载…”）；
项。放置（属性\容量\当前，0）；
物品放置（属性为容量，0）；
储罐清单。添加（项目）；
字符串[]from={ATTRIBUTE_NUMBER，ATTRIBUTE_FUEL，ATTRIBUTE_CAPACITY_CURRENT，ATTRIBUTE_CAPACITY}；
int[]to={R.id.textview_tankitem_编号，R.id.textview_tankitem_燃料，R.id.textview_tankitem_容量}当前，R.id.textview_tankitem_容量}；
适配器=新的SimpleAdapter（getApplicationContext（），tankList，R.layout.tank\u list\u项，from，to）；
setViewBinder（新的TankItemBinder（））；
ListView列表=（ListView）findViewById（R.id.ListView\u tanklistactivity\u列表）；
list.setAdapter（适配器）；
setOnScrollListener（scrollListener）；
list.setOnItemClickListener（onItemClickListener）；
registerForContextMenu（列表）；
}

但我需要这个列表在加载时为空。如何修复此问题？

请共享

TankItemBinder

@0X0nosugar的代码，已添加。这是我的内心世界activity@0X0nosugar，在不同的设备上，屏幕上有5-7个项目。但我不明白这有什么关系。请注意我在帖子中的注释：如果列表至少由一个值初始化，则无论屏幕大小、列表内容以及列表所包含的元素如何，都不会有消息（在我的应用程序中，有十多个不同的列表是根据这个原则建立的，它们都给出了这个错误消息）。
