我有一个:
List<Fixture> allFixture = new List<Fixture>();
每个灯具:
class Fixture
{
public int _id { get; set; }
public string Home { get; set; }
public DateTime matchDate { get; set; }
public string Away { get; set; }
}
我可以在ListAdapter上显示Home []:
ListAdapter = new ArrayAdapter<string>(this, Android.Resource.Layout.SimpleListItem1, allFixture.Select(x => x.Home).ToArray())
但我希望在下面显示如下内容:“Home vs Away”和 DateTime 。 我怎么能这样做?

What Nicola linked提供了正确的信息。对于您明确要求的内容,您需要实施custom adapter并覆盖getView method。
例如:
public class ExampleArrayAdapter extend ArrayAdapterAdapter<MyCustomItem>
{
private Context mContext;
private List<MyCustomItems> mCustomItems;
public ExampleArrayAdapter(Context context, List<MyCustomItem> customItems)
{
mContext = context;
mCustomItems = customItems;
}
@Override
public View getView (int position, View convertView, ViewGroup parent)
{
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// Create the view of your row item here
View rowView = inflater.inflate(R.layout.my_custom_layout, parent, false);
}
}
public class MyActivity extends listActivity
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
List<MyCustomItem> customItems = new ArrayList<MyCustomItems();
// create your items...
ExampleArrayAdapter arrayAdapter = new ExampleArrayAdapter(this, customItems);
setListAdapter(arrayAdapter);
}
}
创建您的Fixture布局并在getView中对其进行充气。
my_custom_layout:
<LinearLayout
android:id="@+id/listItem"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/textTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Default"/>
<TextView
android:id="@+id/textDate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="20140805"/>
</LinearLayout>

尝试扩展ArrayAdapter以使用多个字符串。
你可以扩展它以使用你的类Fixture,然后再膨胀一个新的布局文件而不是simpleListItemLayout。
您需要一个新的xml文件,您将膨胀。
扩展arrayadapter
private class SampleAdapter extends ArrayAdapter<Fixture> {
public InteractiveArrayAdapter(Activity context, List<Model> list) {
super(context, R.layout.rowbuttonlayout, list);
this.context = context;
this.list = list;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = null;
LayoutInflater inflator = context.getLayoutInflater();
view = inflator.inflate(R.layout.YOUR_XML_LAYOUT, null);
//find views that you want to access and populate here.
return view;
}
}
创建一个新的xml文件,这可以是你想要的任何东西,在数组适配器中你会膨胀新的xml。
