我正在尝试创建一个 ListView，其中每个项目都包含一个 TextItem 和一个 ListView（动态长度），但由于某种原因，内部 ListView 中只显示了一个项目。这是不可能的事情还是我做错了什么？
这是我的布局：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/outerListId"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
内部列表项：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Profile Name"
android:id="@+id/nameId"/>
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/innerListId"/>
</RelativeLayout>
代码：
public class ListAllActivity extends Activity {
protected class MyListItem {
public String name;
public List<String> items;
public MyListItem(String name) {
this.name = name;
this.items = items();
}
public List<String> items() {
ArrayList<String> strings = new ArrayList<String>();
strings.add("item1");
strings.add("item2");
return strings;
}
}
public class CustomListViewAdapter extends ArrayAdapter<MyListItem> {
Context context;
public CustomListViewAdapter(Context context, int resourceId, List<MyListItem> items) {
super(context, resourceId, items);
this.context = context;
}
private class ViewHolder {
TextView nameText;
ListView myList;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
MyListItem rowItem = getItem(position);
LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = mInflater.inflate(R.layout.profile_exercises_list_item, null);
holder = new ViewHolder();
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.nameText = (TextView) convertView.findViewById(R.id.profileNameListItemId);
holder.myList = (ListView) convertView.findViewById(R.id.innerListId);
List<String> items = rowItem.items();
holder.nameText.setText(rowItem.name);
ArrayAdapter<String> myarrayAdapter = new ArrayAdapter<String>(convertView.getContext(), android.R.layout.simple_list_item_1, items);
holder.myList.setAdapter(myarrayAdapter);
holder.myList.setTextFilterEnabled(true);
return convertView;
}
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mylayout);
ListView listView = (ListView) findViewById(R.id.outerListId);
ArrayList<MyListItem> allItems = new ArrayList<MyListItem>();
allItems.add(new MyListItem("name1"));
allItems.add(new MyListItem("name2"));
CustomListViewAdapter all = new CustomListViewAdapter(this, android.R.layout.simple_list_item_1, allItems);
listView.setAdapter(all);
listView.setTextFilterEnabled(true);
}
}
