グループビューと子ビューをこのようなリストに結合する方法を見つけようとしています
ただし、代わりに展開可能なリストになります。
ありがとうございました。

このためのサンプル コードを自由に作成しました。ExpandableListViewグループと子を処理するためのカスタム アダプタ (特に角を丸くしたい場合)から拡張する独自のカスタム ビューを作成しmain.xml、複数のカスタム ビューを含めることが最も理にかなっています。スクリーンショットからわかるように、かなり厳密に再現することができました。
コードは次のとおりです。
RoundedExpandableListView.java
public class RoundedExpandableListView extends ExpandableListView {
public RoundedExpandableListView(Context context) {
super(context);
}
public RoundedExpandableListView(Context context, AttributeSet attrs) {
super(context, attrs);
// for setting the background color and rounded corners
int bgColor = attrs.getAttributeIntValue("http://schemas.android.com/apk/res/android", "background", 0xffffff);
TypedArray a = getContext().obtainStyledAttributes(attrs, R.styleable.RoundedExpandableListView);
int radius = a.getInteger(R.styleable.RoundedExpandableListView_radius, 0);
PaintDrawable drawable = new PaintDrawable();
drawable.getPaint().setColor(bgColor);
drawable.setCornerRadius(radius);
setBackgroundDrawable(drawable);
a.recycle();
}
}
GroupedViewAdapter.java
public class GroupedViewAdapter extends BaseExpandableListAdapter {
private Context mContext;
private String[] mGroups;
private Object[][] mChildren;
private int mGroupLayoutId;
private int mChildLayoutId;
private Drawable mTitleDrawable;
public GroupedViewAdapter(Context c, String[] k, Object[][] v, int titleDrawableResId) {
this(c, k, android.R.layout.simple_expandable_list_item_1, v,
android.R.layout.simple_expandable_list_item_1, titleDrawableResId);
}
public GroupedViewAdapter(Context c, String[] k, int groupLayoutResId, Object[][] v,
int childLayoutResId, int titleDrawableResId) {
super();
mContext = c;
mGroups = k;
mChildren = v;
mGroupLayoutId = groupLayoutResId;
mChildLayoutId = childLayoutResId;
mTitleDrawable = mContext.getResources().getDrawable(titleDrawableResId);
mTitleDrawable.setBounds(0, 0, 48, 48); // not necessarily the best way, but just to show example
}
@Override

return mGroups.length;
}

tv.setText(getGroup(groupPosition));
tv.setTag(getGroupId(groupPosition));
// set title group special properties
if (groupPosition == 0) {
tv.setTextSize(20);
tv.setCompoundDrawables(mTitleDrawable, null, null, null);
} else if (isExpanded) {
tv.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.icon_expanded, 0);
} else {
tv.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.icon_collapsed, 0);
}

それはそれである必要があります！幸運を！
