[英]How to add a static row in expandablelistview
如何在每個expandablelistview中將此行添加為靜態行？
這是我的布局充氣機：
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">

android:layout_height="wrap_content" />
<TextView

android:layout_marginLeft="15dp"
android:layout_marginStart="15dp"
android:layout_toRightOf="@+id/txt_rank_standings"
android:layout_toEndOf="@+id/txt_rank_standings"

<TextView

android:layout_marginLeft="15dp"
android:layout_marginStart="15dp"

android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView

android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
/>
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>
我將這一行添加到布局充氣機中，但問題是我得到了以下信息：
在expandablelist視圖中，單行被重復3次。
那么，如何使該行在expandablelistview中保持靜態？
更新：
這是我的片段活動，其中包含expandablelistview：
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/coordinatorLayout"
xmlns:app="http://schemas.android.com/apk/res-auto">
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipe_refresh"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<ExpandableListView
android:id="@+id/elv"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ExpandableListView>
</android.support.v4.widget.SwipeRefreshLayout>
</android.support.design.widget.CoordinatorLayout>
這是自定義行布局：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:padding="10dp"
android:id="@+id/relative_standings"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:text="#"
android:id="@+id/txt_rank_standings"
android:textSize="16sp"
android:layout_alignParentStart="true"
android:layout_alignParentLeft="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:text="TEAM"
android:textSize="16sp"
android:layout_marginLeft="15dp"
android:layout_marginStart="15dp"
android:layout_toRightOf="@+id/txt_rank_standings"
android:layout_toEndOf="@+id/txt_rank_standings"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="15dp"
android:textSize="16sp"
android:layout_marginEnd="15dp"
android:layout_toLeftOf="@+id/txt_points_standings"
android:layout_toStartOf="@+id/txt_points_standings"
android:text="P" />
<TextView
android:id="@+id/txt_points_standings"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="15dp"
android:textSize="16sp"
android:layout_marginEnd="15dp"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:text="PTS" />
</RelativeLayout>
更新：
當我添加頁眉布局時，它可以工作，但是刪除了第一個子行，如下圖所示：
看看這篇文章，其中包含有關如何做到這一點的逐步說明-https: //robusttechhouse.com/how-to-add-header-footer-to-expandablelistview-childview/
為了創建在子視圖中帶有標題的可擴展列表視圖，您將需要四個XML布局文件。
ExpandableListView的主布局 訣竅是獲取第一行並將其設置為標題：
public View getChildView(int groupPosition, int childPosition, boolean b, View view, ViewGroup viewGroup) {
ParentObject currentParent = getGroup(groupPosition);
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//The first row is used as header
if(childPosition == 0){
view = inflater.inflate(R.layout.child_header, null);
TextView txtHeader = (TextView)view.findViewById(R.id.txtHeader);
txtHeader.setText(currentParent.textToHeader);
}
//Fix the prior out of bound exception
if(childPosition > 0 &&* childPosition < getChildrenCount(groupPosition) - 1){
ChildObject currentChild = getChild(groupPosition, childPosition - 1);
view = inflater.inflate(R.layout.child_row, null);
//Set your fields for the header here... i.e
TextView txtChildName = (TextView)view.findViewById(R.id.txtChildName);
TextView txtChildAge = (TextView)view.findViewById(R.id.txtChildAge);
}
return view;
}
然后將自定義適配器的getChildrenCount()返回值增加1 ，以適應我們用於標頭的內容。 像這樣：
@override
public int getChildrenCount(int i){
return yourModel.get(i).childObjects.size() + 1;
}
完全容納它的布局
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<ExpandableListView
android:id="@+id/elv"
android:layout_width="match_parent"
android:layout_height="match_parent"></ExpandableListView>
</RelativeLayout>
父行的布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:background="@color/parent_background"
android:paddingLeft="@dimen/padding_left"
android:layout_margin="5dp"
android:layout_height="match_parent">
<TextView
android:id="@+id/txtMother"
android:layout_marginTop="10dp"
android:textStyle="bold"
android:layout_marginBottom="5dp"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/txtFather"
android:layout_marginBottom="10dp"
android:textStyle="bold"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
子行的布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:background="@color/child_background"
android:paddingLeft="@dimen/padding_left"
android:layout_height="match_parent">
<TextView
android:id="@+id/txtChildName"
android:textColor="@android:color/holo_orange_dark"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"/>
<TextView
android:id="@+id/txtChildAge"
android:textColor="@android:color/holo_orange_dark"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"/>
</LinearLayout>
頁眉的布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="@color/hf_background"
android:paddingLeft="@dimen/padding_left">
<TextView
android:id="@+id/txtHeader"
android:textColor="@android:color/holo_green_light"
android:layout_width="match_parent"
android:gravity="center_vertical"
android:textStyle="bold"
android:text="Header"
android:layout_height="50dp" />
</LinearLayout>
