如何在Listview中使用自定义对象的属性.如果我使用字符串列表实现ArrayAdapter,它在Listview中显示正常,但是当我使用自定义对象列表时,它只输出内存地址.

我到目前为止的代码:

ArrayList<CustomObject> allObjects = new ArrayList<>();

allObjects.add("title", "http://url.com"));


  ArrayAdapter<NewsObject> adapter = new ArrayAdapter<NewsObject>(this,
                android.R.layout.simple_list_item_1, android.R.id.text1, allNews);


        // Assign adapter to ListView
        listView.setAdapter(adapter);


        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                Uri uri = Uri.parse( "http://www.google.com" );
                startActivity(new Intent(Intent.ACTION_VIEW, uri));
            }
        });

这里有一个类似的问题,但这不是我需要的,因为我只需要在列表视图中显示标题,然后点击提取网址.

我从这个活动开始：

adapter = new ItemAdapter(Items.this, items, totals);
        setListAdapter(adapter);

现在这里是 ItemAdapter：

public class ItemAdapter extends ArrayAdapter<String> {

private final List<String> items;
private final List<String> totals;
private final Context context;

public ItemAdapter(Context context, List<String> items,
        List<String> totals) {
    super(context, R.layout.item_row_layout, items);
    this.context = context;
    this.items = items;
    this.totals = totals;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    View rowView = inflater
            .inflate(R.layout.item_row_layout, parent, false);
    TextView t1 = (TextView) rowView.findViewById(R.id.itemName);
    TextView t2 = …
