我有一个使用自定义适配器的可扩展列表视图的项目。我的列表视图可以正常工作，但问题是在这两个问题开始之后：1-错误的子点击开始。我点击的孩子不会工作，但另一个 2- 在一些点击后应用程序崩溃了。

这是我的适配器：

我可以对您说的第一件事是，您必须对每个视图使用标签，以便您轻松使用视图，然后您不需要检查密钥，如下面的代码：

    convertView.setTag(groupPosition*100 + childPosition);

使用此代码，您可以为每个子项设置一个唯一标签，然后在 onClick 方法中，您可以获得类似v.getTag(). 这将为您提供独特的标签，您可以轻松获得您的孩子位置。

我在您的代码中看到的第二件事不是真的是当您想要检查您使用的字符串时==。您必须.equal()在字符串检查中使用。

//编辑

您必须放入seTag()getChildView()。

为了让您的孩子使用以下代码：

int chiledposClicked = v.getTag() % 100;
int groupPosClicked = v.getTag() / 100;

然后你可以让你的孩子

Childtem.get(groupPosClicked).get(chiledposClicked);

结果

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



        final int myGroupPos = groupPosition;
        final DisplayMetrics dm = new DisplayMetrics();
        activity.getWindowManager().getDefaultDisplay().getMetrics(dm);

        previousGroup = myGroupPos;
        tempChild = (ArrayList<String>) Childtem.get(groupPosition);
        TextView text = null;
        if (convertView == null) {
            convertView = minflater.inflate(R.layout.childrow, null);
        }

        convertView.setTag(groupPosition*100 + childPosition);
        /*
        text = (TextView) convertView.findViewById(R.id.textView1);
        text.setText(tempChild.get(childPosition));
        //typeface
        text.setTypeface(G.typeFacePrs);
        */
        //************
        convertView.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {


                int chiledposClicked = v.getTag() % 100;
                int groupPosClicked = v.getTag() / 100;

                 log.d("Group pos and child pos",""+groupPosClicked +" "+ chiledposClicked);

                 Childtem.get(groupPosClicked).get(chiledposClicked);

                log.d("chiled is",Childtem.get(groupPosClicked).get(chiledposClicked));
                ReportActivity.mahdiCustomToast(Childtem.get(groupPosClicked).get(chiledposClicked)
                                        , 1);


                loadContent(Childtem.get(groupPosClicked).get(chiledposClicked));


            }

            private void loadContent(String key) {




            }
        });
        return convertView;
    }

您的转换视图在以下行中为空：

    convertView.setTag(groupPosition*100 + childPosition);

在检查 null 后尝试这样做：

    final int myGroupPos = groupPosition;
    final DisplayMetrics dm = new DisplayMetrics();
    activity.getWindowManager().getDefaultDisplay().getMetrics(dm);

    previousGroup = myGroupPos;
    tempChild = (ArrayList<String>) Childtem.get(groupPosition);
    TextView text = null;
    if (convertView == null) {
        convertView = minflater.inflate(R.layout.childrow, null);
    }

    convertView.setTag(groupPosition*100 + childPosition);
