Question

我正在制作一个闹钟，所以我想打开可扩展列表视图中单击组父级的设置，但点击组时没有发生任何事情。此外，任何像getchildrencount这样的子方法都不起作用。通过调试了解。这是我的文件。我的群组视图正常或可见。

适配器文件：

public ExpandableAdapter(Context ctx, ArrayList<ParentBean> parentlist, 
ArrayList<ChildBean> childlist){

    this.ctx = ctx;
    this.parentlist = parentlist;
    this.childlist = childlist;
     map = new HashMap<>();
    for(ParentBean pb : parentlist){
        ;

    map.put(pb,childlist);
    Log.e("childliset",String.valueOf(childlist.size()));
}}
@Override
public int getGroupCount() {
    Log.d("problem","1");
    for(ParentBean b : parentlist){
        Log.e("parentlist",b.toString());
    }

    return parentlist.size();
}

@Override
public int getChildrenCount(int groupPosition) {
    Log.e("problem", "30");
    Log.e("childlist",String.valueOf(childlist.size()));

    return map.get(groupPosition).size();
}

@Override
public Object getGroup(int groupPosition) {
    Log.e("problem2 ", parentlist.get(groupPosition).toString());
    Log.e("groupPosition",String.valueOf(groupPosition));
    return parentlist.get(groupPosition);
}

@Override
public Object getChild(int groupPosition, int childPosition) {
    Log.e("problem3",childlist.get(childPosition).toString());
    return childlist.get(childPosition);
}

@Override
public long getGroupId(int groupPosition) {
    Log.e("problem4",String.valueOf(groupPosition));
    return groupPosition;
}

@Override
public long getChildId(int groupPosition, int childPosition) {
    Log.e("problem4",String.valueOf(childPosition));
    return childPosition;
}

@Override
public boolean hasStableIds() {
    return false;
}

@Override
public View getGroupView(int groupPosition, boolean isExpanded, View 
convertView, ViewGroup parent) {

    ParentBean header = (ParentBean) this.getGroup(groupPosition);

        if(convertView == null){
            LayoutInflater inflater = (LayoutInflater) 
 this.ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(R.layout.parent_view,null);
        }
        Log.e("Mision2",header.toString());
        TextView alarm_time = 
  (TextView)convertView.findViewById(R.id.alarm_time);
    if(header.getHour()>=12){
        header.setHour(header.getHour()-12);
    }if(header.getHour()<10){
        alarm_time.setText("0"+header.getHour()+" : "+header.getMinute());
    }else{
    alarm_time.setText("0"+header.getHour()+" : "+header.getMinute());}

    TextView date = (TextView)convertView.findViewById(R.id.date);
    if(header.getDate()<10){
        date.setText("0"+header.getMonth()+"-"+header.getDate()+"-
  "+header.getMinute());
    }else {
        date.setText(header.getMonth() + "-" + header.getDate() + "-" + 
 header.getMinute());
    }



    Log.e("mission ", "possible");
    return convertView;
}

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

    Log.e("mission","impossible");
    ChildBean footer = 
(ChildBean)this.getChild(groupPosition,childPosition);
    if (convertView==null){
        LayoutInflater inflater = 
(LayoutInflater)this.ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.child_view,parent,false);

    }







    return convertView;
}

Answer 1

每个人都在寻找上述问题的答案。实际上，当您单击组视图时，子方法会起作用。在我的情况下，我必须添加

机器人：descendantFocusability = “blocksDescendants”

这个语句在我的parent_view.xml的父布局

中

Chlid方法在BaseExpandable ListAdapter中不起作用
