私は3つのレベルの展開可能なリストビューで作業しています。すべては、展開可能なリストビューの2番目と3番目のレベルのテキストビューの幅が内容にラップしていて、レイアウトで指定したように親に一致しないと完全に期待しています。ここで拡張可能なリストビューでテキストビューを作成する方法MATCH_PARENT
は、親レベルのアダプターのための私のコードです：
public class ParentLevelAdapter extends BaseExpandableListAdapter
{
private final Context mContext;
private final List<String> mListDataHeader;
private final Map<String, List<String>> mListData_SecondLevel_Map;
private final Map<String, List<String>> mListData_ThirdLevel_Map;
private List<String> stringList = new ArrayList<>();
Activity activity;
public ParentLevelAdapter(Context mContext, List<String> mListDataHeader) {
activity = (Activity) mContext;
this.mContext = mContext;
this.mListDataHeader = new ArrayList<>();
this.mListDataHeader.addAll(mListDataHeader);
// SECOND LEVEL
String[] mItemHeaders = new String[0];
mListData_SecondLevel_Map = new HashMap<>();
int parentCount = mListDataHeader.size();
mItemHeaders = mContext.getResources().getStringArray(R.array.items_array_expandable_level_two);
mListData_SecondLevel_Map.put(mListDataHeader.get(i), Arrays.asList(mItemHeaders));
}
// THIRD LEVEL
String[] mItemChildOfChild;
mListData_ThirdLevel_Map = new HashMap<>();
for (Object o : mListData_SecondLevel_Map.entrySet()) {
Map.Entry entry = (Map.Entry) o;
Object object = entry.getValue();
if (object instanceof List) {
Collections.addAll(stringList, (String[]) ((List) object).toArray());
mItemChildOfChild = mContext.getResources().getStringArray(R.array.items_array);
}
}
}
}
@Override
public Object getChild(int groupPosition, int childPosition) {
return childPosition;
}
@Override
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
@Override
public View getChildView(int groupPosition, int childPosition,boolean isLastChild, View convertView, ViewGroup parent)
{
final CustomExpandableListView secondLevelExpListView = new CustomExpandableListView(this.mContext);
String parentNode = (String) getGroup(groupPosition);
secondLevelExpListView.setAdapter(new SecondLevelAdapter(this.mContext, mListData_SecondLevel_Map.get(parentNode), mListData_ThirdLevel_Map));
secondLevelExpListView.setGroupIndicator(null);
secondLevelExpListView.setOnGroupExpandListener(new ExpandableListView.OnGroupExpandListener() {
int previousGroup = -1;
@Override
public void onGroupExpand(int groupPosition) {
if (groupPosition != previousGroup)
secondLevelExpListView.collapseGroup(previousGroup);
previousGroup = groupPosition;
}
});
secondLevelExpListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
@Override
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
return false;
}
});
return secondLevelExpListView;
}
@Override
public int getChildrenCount(int groupPosition) {
return 1;
}
@Override
public Object getGroup(int groupPosition) {
return this.mListDataHeader.get(groupPosition);
}
@Override
public int getGroupCount() {
return this.mListDataHeader.size();
}
@Override
public long getGroupId(int groupPosition) {
return groupPosition;
}
@Override
public View getGroupView(int groupPosition, boolean isExpanded,View convertView, ViewGroup parent) {
String headerTitle = (String) getGroup(groupPosition);
if (convertView == null) {
LayoutInflater layoutInflater = (LayoutInflater) this.mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = layoutInflater.inflate(R.layout.expandable, parent, false);
}
TextView lblListHeader = (TextView) convertView.findViewById(R.id.lblListHeader);
lblListHeader.setText(headerTitle);
return convertView;
}
@Override
public boolean hasStableIds() {
return true;
}
@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
}
第2レベルアダプターコード：
public class SecondLevelAdapter extends BaseExpandableListAdapter
{
private final Context mContext;
private final List<String> mListDataHeader;
private final Map<String, List<String>> mListDataChild;
public SecondLevelAdapter(Context mContext, List<String> mListDataHeader, Map<String, List<String>> mListDataChild) {
this.mContext = mContext;
this.mListDataHeader = mListDataHeader;
this.mListDataChild = mListDataChild;
}
@Override
public Object getChild(int groupPosition, int childPosition) {
return this.mListDataChild.get(this.mListDataHeader.get(groupPosition)).get(childPosition);
}
@Override
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
@Override
public View getChildView(int groupPosition, int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
final String childText = (String) getChild(groupPosition, childPosition);
if (convertView == null) {
LayoutInflater layoutInflater = (LayoutInflater) this.mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = layoutInflater.inflate(R.layout.expandable_third, parent, false);
}
TextView txtListChild = (TextView) convertView.findViewById(R.id.lblListThird);
txtListChild.setText(childText);
return convertView;
}
@Override
public int getChildrenCount(int groupPosition) {
try {
return this.mListDataChild.get(this.mListDataHeader.get(groupPosition)).size();
} catch (Exception e) {
return 0;
}
}
@Override
public Object getGroup(int groupPosition) {
return this.mListDataHeader.get(groupPosition);
}
@Override
public int getGroupCount() {
return this.mListDataHeader.size();
}
@Override
public long getGroupId(int groupPosition) {
return groupPosition;
}
@Override
public View getGroupView(int groupPosition, boolean isExpanded,View convertView, ViewGroup parent) {
String headerTitle = (String) getGroup(groupPosition);
if (convertView == null) {
LayoutInflater layoutInflater = (LayoutInflater) this.mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = layoutInflater.inflate(R.layout.expandable_list_second, parent, false);
}
TextView lblListHeader = (TextView) convertView
.findViewById(R.id.lblListItem);
lblListHeader.setText(headerTitle);
return convertView;
}
@Override
public boolean hasStableIds() {
return true;
}
@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
}
と一つだけのテキストボックスが
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="@+id/lblListThird"
android:layout_width="match_parent"
android:layout_height="@dimen/_35sdp"
android:textColor="@color/colorWhite"
android:paddingLeft="@dimen/_20sdp"
android:layout_marginTop="@dimen/_10sdp"
android:textSize="25sp"
android:layout_gravity="center"
android:gravity="center|start" />
もっと正確に言うと、私は何を言おうとしているのかをはっきりと見せる画像をアップロードしています。それを見てください。開発者のオプションから「レイアウトレイアウトの表示」をオンにしました。これは、テキストビューがテキストの内容をラップしていて、親に一致していないことを示しています。テキストの長さだけでなく、全体を通してクリック可能にしたいと思っています。 
私が間違っていることを教えてください。これを解決するために何が必要かを教えてください。
