Question

我一直在尝试使用自定义适配器为列表视图获取此自定义xml布局以永久工作（呈现）。没有错误被抛出，顶级textview只是拒绝渲染（我在Android设备管理器中检查）。我还在getView函数中调试了它，并确保正确填充了对象列表，并且textview上的findviewbyid工作正常。

继承人xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="5dp"
android:background="@drawable/itembackground">

<ImageView
    android:id="@+id/itemicon"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:layout_alignParentBottom="true"
    android:layout_alignParentTop="true"
    android:layout_marginRight="6dip" />

<TextView
    android:id="@+id/itemtopLine"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_above="@+id/itembotLine"
    android:layout_alignParentTop="true"
    android:layout_alignParentRight="true"
    android:layout_toRightOf="@id/itemicon"
    android:ellipsize="marquee"
    android:singleLine="true"
    android:textSize="16sp" />

<TextView
    android:id="@+id/itembotLine"
    android:layout_width="fill_parent"
    android:layout_height="20dp"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:layout_toRightOf="@id/itemicon"
    android:ellipsize="marquee"
    android:singleLine="true"
    android:textSize="12sp" />
</RelativeLayout>

继承人适配器

public class SpaceAdapter extends ArrayAdapter<SpaceItem>{
     public SpaceAdapter(Context context, int resource, ArrayList<SpaceItem>       items) {
    super(context, resource, items);
     }

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View v = convertView;

    if (v == null){
        v = LayoutInflater.from(getContext()).inflate(R.layout.space_item, null);
    }

    SpaceItem item = getItem(position);

    ImageView icon = (ImageView) v.findViewById(R.id.itemicon);
    TextView name = (TextView) v.findViewById(R.id.itemtopLine);
    TextView prop = (TextView) v.findViewById(R.id.itembotLine);

    if (item != null){
        icon.setImageDrawable(item.spaceItemIcon);
        name.setText(item.spaceItemName);
        prop.setText(item.spaceItemDescription);
    }
    else {
        icon.setImageDrawable(getContext().getResources()
                                          .getDrawable(android.R.drawable.btn_star, null));
        name.setText("Default");
        name.setText("kek");
    }

    return v;
}
}

这是项目

public class SpaceItem {
    public Drawable spaceItemIcon;
    public String spaceItemName;
    public String spaceItemDescription;
    public SpaceItem (Drawable ico, String name, String d){
        spaceItemDescription = d;
        spaceItemIcon = ico;
        spaceItemName = name;
        }
    }
