ListView는 그 아래에있는 모든 것을 포함합니다.

Question

ListView에서 한 국가의 언어를 나열하는 클래스를 구현하고 있습니다. 바로 아래에 그룹 제목 및 해당 언어의 모든 버전이 하위 항목 인 주요 언어가 포함 된 ExpandableListView가 있습니다.

현재 데이터는 올바르게 채워지지만 목록보기는 구분선과 ExpandableListView 위에 표시됩니다. 사용자가 두 목록의 높이를 정적으로 정의하지 않고 두 목록의 모든 항목을 스크롤 할 수있게하려고합니다. 현재 ListView에 더 많은 항목이있는 경우 한 화면에 표시하면 목록보기와 그 위에있는 항목 만 표시되고 ExpandableListView를 덮습니다.

나는 두 개의 어댑터 ExpandableListView에 대한 ListView 다른 하나는 다른 있습니다.

LanguageExpandableAdapter.java

public class LanguageExpandableAdapter extends BaseExpandableListAdapter{ 
Context mContext; 
private ArrayList<LanguageDataType> titles = new ArrayList<LanguageDataType>(); 
private ArrayList<ArrayList<LanguageDataType>> languages = new ArrayList<ArrayList<LanguageDataType>>();

     titles.add(value); 
    } 

    for (ArrayList<LanguageDataType> value: inputLanguages) { 
     languages.add(value); 
    } 

} 

public Object getChild(int groupPosition, int childPosition) { 
    return languages.get(groupPosition).get(childPosition).getLocationName();

    return childPosition; 
}

    String myText = this.getChild(groupPosition, childPosition).toString(); 
    childeTitle.setText(myText); 

    return v;

아무도 내가 ListView를 통해 내 extendableListView을에 지속적 스크롤을 할 수있는 방법 어떤 제안이있는 경우 나는 거리다. 많이 감사드립니다.

Answer 1

먼저 화면 맨 아래에 정렬 된 ExpandableListView를 정의한 다음 Listview를 ExpandableListView 위에 정의하십시오.

Answer 2

두 가지 방법으로 화면을 분할하는 방법은 두 가지 스크롤 가능한 항목을 스크롤하는 방법을 알지 못합니다.

일반 목록보기가 두 개인 경우 해결책을 찾을 수 있지만 listview와 확장 목록보기는 해당 솔루션에서 작동하지 않습니다.

내가 가지고 올 수있는 최선 포함하도록 XML에 두 개의 목록보기 정의를 변경하는 것입니다 :

android:layout_height="0dp" 
android:layout_weight="1" 

그들 사이의 화면을 splict 화면에 둘을 유지하도록 원인이있다.
