【问题描述】：
我有几个名字的动态列表。但是ListView 在整个列表项的下方和上方留下了额外的空间。
routes_recycler_listview.xml，这里，我用过这个：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:id="@+id/header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@android:color/transparent">
<TextView
android:id="@+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:gravity="center_vertical"
android:paddingEnd="0dp"
android:paddingStart="10dp"
android:textColor="@color/md_black_1000"
android:textSize="20sp" />
</RelativeLayout>
<com.github.aakira.expandablelayout.ExpandableRelativeLayout
android:id="@+id/expandableLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@id/header"
android:background="@drawable/recycler_item_bg"
app:ael_duration="400"
app:ael_expanded="true"
app:ael_orientation="vertical">
<ListView
android:id="@+id/lv_routes_assigned"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:textColor="@color/fontColor"
android:textSize="16sp" />
</com.github.aakira.expandablelayout.ExpandableRelativeLayout>
</RelativeLayout>
但是，我明白了，
编辑
删除android:layout_centerInParent="true"后：
在我的RecyclerViewRecyclerAdapter 课程中，我使用以下内容：
ViewHolder 班级：
public static class ViewHolder extends RecyclerView.ViewHolder {
public TextView textView;
public ListView routesAssign;
public ExpandableRelativeLayout expandableLayout;
public ViewHolder(View v) {
super(v);
textView = (TextView) v.findViewById(R.id.textView);
routesAssign = (ListView) v.findViewById(R.id.lv_routes_assigned);
expandableLayout = (ExpandableRelativeLayout) v.findViewById(R.id.expandableLayout);
}
}
onBindViewHolder方法：
holder.textView.setText(item.getDateString());
CustomAdapter testAdapter = new CustomAdapter(context, item.getRoutes());
holder.routesAssign.setAdapter(testAdapter);
holder.routesAssign.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int pos, long id) {
Intent i = new Intent(context, RoutesShapesActivity.class);
Log.e("id - onItemClick", item.getRoutes().get(pos).getId() + "-- Test --");
i.putExtra("route_id", item.getRoutes().get(pos).getId());
i.putExtra("assigned_id", item.getRoutes().get(pos).getAssignId());
i.putExtra("update", item.getRoutes().get(pos).getIsUpdated());
context.startActivity(i);
}
});
RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
item.getRoutes().size() * 200);
p.addRule(RelativeLayout.BELOW, R.id.header);
p.addRule(RelativeLayout.CENTER_IN_PARENT, R.id.header);
holder.expandableLayout.setLayoutParams(p);
holder.expandableLayout.setInterpolator(Utils.createInterpolator(Utils.DECELERATE_INTERPOLATOR));
holder.expandableLayout.setExpanded(true);
onCreateViewHolder 方法：
@Override
public ViewHolder onCreateViewHolder(final ViewGroup parent, final int viewType) {
this.context = parent.getContext();
return new ViewHolder(LayoutInflater.from(context)
.inflate(R.layout.routes_recycler_listview, parent, false));
}
在我的CustomAdapter 课堂上：
getItem 方法：
@Override
public Routes getItem(int position) {
return data.get(position);
}
getView 方法：
public View getView(int position, View convertView, ViewGroup parent) {
// Get the data item for this position
Routes route = getItem(position);
// Check if an existing view is being reused, otherwise inflate the view
if (convertView == null) {
convertView = inflater.inflate(R.layout.route_assigned_list, parent, false);
}
// Lookup view for data population
TextView tvName = (TextView) convertView.findViewById(R.id.route_assign_text_view);
ImageView imageView = (ImageView) convertView.findViewById(R.id.route_assign_pause_state);
Log.e("Test --- ", route.getRouteName());
tvName.setText(route.getRouteName());
return convertView;
}
Routes 类中的 getter 和 setter 方法。这里，
public class Routes {
//
// "assignId": 22,
// "routeId": 15,
// "routeName": "NY-CLSTR23",
// "createdDate": "2016-04-15 09:51:45"
@SerializedName("assignId")
private int assignId;
@SerializedName("assignDate")
private String assignDate;
@SerializedName("routeId")
private int id;
@SerializedName("routeName")
private String routeName;
@SerializedName("createdDate")
private String createdDate;
@SerializedName("isUpdated")
private String isUpdated;
/*"assignId": 167,
"assignDate": "2016-06-17",
"routeId": 137,
"routeName": "Test June 16",
"createdDate": "2016-06-16 00:14:27",
"isUpdated": "true"*/
public int getAssignId() {
return assignId;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getRouteName() {
return routeName;
}
public void setRouteName(String routeName) {
this.routeName = routeName;
}
public String getCreatedDate() {
return createdDate;
}
public void setCreatedDate(String createdDate) {
this.createdDate = createdDate;
}
public void setAssignId(int assignId) {
this.assignId = assignId;
}
public String getAssignDate() {
return assignDate;
}
public void setAssignDate(String assignDate) {
this.assignDate = assignDate;
}
public String getIsUpdated() {
return isUpdated;
}
public void setIsUpdated(String isUpdated) {
this.isUpdated = isUpdated;
}
}
我在这里真的很难过。那么，如何从 listview 中删除该空间？

将
marginTop="-15dp"添加到ExpandableRelativeLayout
