我有5个级别的多级可扩展列表视图。所有孩子都可以看到最多3个级别，后来在第4级我缺少一些项目，在第5级我只能看到1个项目。每个级别有4个元素，并且是固定的。似乎expandablelist有所有项目，但身高有问题。因此，我必须更正此高度设置才能使显示正确。我已经将MeasureSpec模式更改为2300的值，一切都很完美但看起来不太好，因为当第3级和第4级没有扩展时，有很多可用空间。
我已将expandablelistview高度设置为match_parent
更新：包含代码信息
这是3级，1级，2级的脚本是类似的
private class Level3 extends BaseExpandableListAdapter {
ViewHolder holder;
LEVELS[] level;
pratyantarDasha(LEVELS[] level){
this.level = new planetData[level.length];
System.arraycopy(level,0,this.level,0,level.length);
}
@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) {
int height=groupPosition*72;
final CustExpListview level4 = new CustExpListview(ctx);
level4.setAdapter(new Level4(level[groupPosition].nextLevel));
level4.setGroupIndicator(ContextCompat.getDrawable(ctx,R.drawable.expand_collapse));
final int[] lastExpPosition = {-1};
level4.setOnGroupExpandListener(new ExpandableListView.OnGroupExpandListener() {
@Override
public void onGroupExpand(int groupPosition) {
if (lastExpPosition[0] != -1 && groupPosition != lastExpPosition[0]) {
level4.collapseGroup(lastExpPosition[0]);
}
lastExpPosition[0] = groupPosition;
}
});
level4.setPadding((int)ctx.getResources().getDimension(R.dimen.dp2)*5,(int)ctx.getResources().getDimension(R.dimen.dp2),(int)ctx.getResources().getDimension(R.dimen.dp2),(int)ctx.getResources().getDimension(R.dimen.dp2));
return level4;
}
@Override
public int getChildrenCount(int groupPosition) {
return 1;
}
@Override
public Object getGroup(int groupPosition) {
return groupPosition;
}
@Override
public int getGroupCount() {
return 4;
}
@Override
public long getGroupId(int groupPosition) {
return groupPosition;
}
@Override
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
if(convertView == null ) {
LayoutInflater inf = (LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inf.inflate(R.id.textViewLayout4Exp, parent,false);
holder = new ViewHolder();
holder.planet = (TextView) convertView.findViewById(R.id.expTV);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.value.setText(String.valueOf(level[groupPosition].value));
return convertView;
}
@Override
public boolean hasStableIds() {

}
第4级剧本
private class Level4 extends BaseExpandableListAdapter {
ViewHolder holder;
LEVELS[] level;
Level4(LEVELS[] level){
this.level = new LEVELS[level.length];
System.arraycopy(level,0,this.level,0,level.length);
}
@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) {
if(convertView == null ) {
LayoutInflater inf = (LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inf.inflate(R.id.textViewLayout4Exp, parent,false);
holder = new ViewHolder();
holder.planet = (TextView) convertView.findViewById(R.id.expTV);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.planet.setText(String.valueOf(level[groupPosition].nextLevel[childPosition].value));
return convertView;
}
@Override
public int getChildrenCount(int groupPosition) {
return 4;
}
@Override
public Object getGroup(int groupPosition) {
return groupPosition;
}
@Override
public int getGroupCount() {
return 4;
}
@Override
public long getGroupId(int groupPosition) {
return groupPosition;
}
@Override
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
if(convertView == null ) {
LayoutInflater inf = (LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inf.inflate(R.id.textViewLayout4Exp, parent,false);
holder = new ViewHolder();
holder.value = (TextView) convertView.findViewById(R.id.expTV);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.value.setText(String.valueOf(level[groupPosition].value));
return convertView;
}
@Override
public boolean hasStableIds() {
// TODO Auto-generated method stub
return true;
}
@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
// TODO Auto-generated method stub
return true;
}
}
这是自定义的expandablelistview类
public class CustExpListview extends ExpandableListView {
public CustExpListview(Context context) {
super(context);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
widthMeasureSpec = MeasureSpec.makeMeasureSpec(MeasureSpec.getSize(widthMeasureSpec), MeasureSpec.EXACTLY);
heightMeasureSpec = MeasureSpec.makeMeasureSpec(99999,MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
