android - 一部の子がクリックすると、展開可能なリストビューがクラッシュする

Question

カスタムアダプターで展開可能なリストビューを使用するプロジェクトがあります。私のリストビューは正しく動作しますが、問題はこれら2つの問題が始まる間です.1-間違った子のonclickが開始されます。クリックした子は機能しませんが、別の2-いくつかのクリックの後、アプリがクラッシュします。

これは私のアダプターです：

最初に言えることは、ビューを簡単に操作できるように各ビューにタグを使用する必要があり、次のコードのようにキーを確認する必要がないということです。

    convertView.setTag(groupPosition*100 + childPosition);

このコードでは、子アイテムごとに 1 つの一意のタグがあり、onClick メソッドでのようなタグを取得できますv.getTag()。これにより、独自のタグが取得され、子の位置を簡単に取得できます。

私があなたのコードで目にする2番目のことは、あなたが使用する文字列をチェックしたいときです==。.equal()文字列チェックで使用する必要があります。

//編集

seTag()getChildView()に入れる必要があります。

あなたの子供を取得するには、次のコードを使用します。

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

その後、あなたはあなたの子供を手に入れることができます

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

結果

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;
    }

あなたの変換ビューは、次の行で null です:

    convertView.setTag(groupPosition*100 + childPosition);

nullをチェックした後、試してみてください：

    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);
