expandableListView内の特定の位置に値を設定する方法

Question

ExpandableListView.Butを作成しました。特定の項目の値をすべての項目に設定すると問題が発生します。これを解決する方法を理解できません。

これは私のコードです。

direct_referal.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/layoutfaq" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_weight="1" 
    android:gravity="center_horizontal" 
    android:orientation="vertical" 
    android:padding="25dp" > 

    <ExpandableListView 
     android:id="@+id/lvExp" 
     android:layout_height="match_parent" 
     android:layout_width="match_parent" 
     android:layout_marginTop="10dp" 
     android:padding="10dp" 
     android:cacheColorHint="#00000000"/> 
</LinearLayout> 

これは私のメインのXMLファイルです。

DirectReferal.java

これは、我々はすべての切り抜いた値を設定したいこのclass.in私のアダプタであります子フィールドと親フィールドは同じですが、すべてのフィールドに同じ値が設定されています。 この画像の出力を見ることができます。 enter image description here

私はこの問題を解決できますか、私は控えめではありません。 助けてください。

Answer 1

getChildViewメソッドgand etGroupViewメソッドを修正してください。コードは次のようになります。

あなたは間違いだったかを理解することができます

public View getChildView(int groupPosition, final int childPosition, 
      boolean isLastChild, View convertView, ViewGroup parent) { 

     String slNo = _slNo.get(_userID.get(groupPosition)).get(0); 
     String childName = _name.get(_userID.get(groupPosition)).get(0); 
     String childCity = _city.get(_userID.get(groupPosition)).get(0); 

     if (convertView == null) { 
      LayoutInflater infalInflater = (LayoutInflater) this._context 
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      convertView = infalInflater.inflate(R.layout.list_item, null); 
     } 

     TextView txtListChildslno = (TextView) convertView.findViewById(R.id.lblListItemslno); 
     TextView txtListChildname = (TextView) convertView.findViewById(R.id.lblListItemname); 
     TextView txtListChildcity = (TextView) convertView.findViewById(R.id.lblListItemcity); 

     txtListChildslno.setText(slNo); 
     txtListChildname.setText(childName); 
     txtListChildcity.setText(childCity); 

     return convertView; 
    } 




@Override 
public View getGroupView(int groupPosition, boolean isExpanded, 
     View convertView, ViewGroup parent) { 
    String headerTitle = (String) getGroup(groupPosition); 
    if (convertView == null) { 
     LayoutInflater infalInflater=(LayoutInflater)this._context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     convertView = infalInflater.inflate(R.layout.list_group, null); 
    } 

    TextView lblListHeaderuserid = (TextView) convertView.findViewById(R.id.lblListHeaderuserid); 
    TextView lblListHeaderjoindate = (TextView) convertView.findViewById(R.id.lblListHeaderjoindate); 

    lblListHeaderuserid.setText(headerTitle); 
    lblListHeaderjoindate.setText(_joiningDate.get(groupPosition)); 

    return convertView; 
} 

・ホープ.. 私は、コードをテストし、それが動作します。
