Java 重新填充ArrayList后的IndexOutOfBoundsException（仅限棉花糖）

我的设置如下：在onCreate中，我按如下方式初始化ArrayList：

textList = new ArrayList<HashMap<String, String>>();

// unrelated code ...

if (isConnected()) {
    new DisplayTextTask().execute(sectionId);
}

但是，由于我不希望上一页的陈旧文本保留在屏幕上，因此我在异步任务中执行以下操作：

private class DisplayTextTask extends AsyncTask<String, Void, String> {

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        textList.clear();
    }

    @Override
    protected String doInBackground(String... urls) {
        // json parsing is called in getData()
        try {
            return getData(urls[0]);
        } catch (IOException e) {
            return "Could not load text";
        }
    }

---

解决方法：在调用clear并在postExecute（）中重新连接适配器之前，我必须先断开适配器与ListView的连接，我猜Marshmallow对数据绑定更严格

show logcat StackTrace没有logcat，我一点也不知道。一种想法可能是，在6.0上，Clear（）方法可能已经更改。我会尝试一个alist.removeAll（alist），看看clear是否是问题所在，如果是的话，我会向谷歌报告，因为安卓M仍在唯冠上，目前还没有稳定的发布版本。@ρцσѕρєK更新为logcat@irvanjit：请发布

HeaderViewListAdapter

classcode@CptEric ^. 尝试移除，同样的事情也会发生。为什么不使用RecyclerView？为什么要为M开发，但仍然使用ListView？

private class DisplayTextTask extends AsyncTask<String, Void, String> {

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        textList.clear();
    }

    @Override
    protected String doInBackground(String... urls) {
        // json parsing is called in getData()
        try {
            return getData(urls[0]);
        } catch (IOException e) {
            return "Could not load text";
        }
    }
