【问题描述】：

我有一个 ListView 的活动。在每个列表项中显示TextView。使用这些方法 EditText#setTextIsSelectable ， EditText#setEllipsize 和 EditText#setSingleLine 切换所选位置的属性。单击第一项效果很好。但是当我点击另一个项目时，我得到了***Error。

以下是我的代码示例。如果我做错了，请告诉我。

提前致谢。

编辑：

在ListView#onItemClickListener 中调用notifyDatasetChanged 时遇到问题。

【参考方案1】：

我终于找到了解决问题的方法。我删除了MyAdapter 中的ViewHolder 模式

private static class MyAdapter extends BaseAdapter 
    private static final String TAG = "HistoryAdapter";
    private final LayoutInflater inflater;
    private int mSelectedPosition = -1;
    private String[] mItems;

    public MyAdapter(Context context, String[] mItems) 
        this.mItems = mItems;
        inflater = LayoutInflater.from(context);
    



    public void setSelectedPosition(int mSelectedPosition) 
        this.mSelectedPosition = mSelectedPosition;
    

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) 

        convertView = inflater.inflate(R.layout.selectable_text_layout, null, false);
        TextView selectableTV = (TextView) convertView.findViewById(R.id.selectableTextView);

        selectableTV.setText(getItem(position));

        if (position == mSelectedPosition) 
            Log.d(TAG, "getView() called with: " + "position = [" + position + "], selected = " + true);
            selectableTV.setTextIsSelectable(true);
            selectableTV.setSingleLine(false);
            selectableTV.setEllipsize(null);
         else 
            Log.d(TAG, "getView() called with: " + "position = [" + position + "], selected = " + false);
            selectableTV.setTextIsSelectable(false);
            selectableTV.setSingleLine(true);
            selectableTV.setEllipsize(TextUtils.TruncateAt.END);
        

        return convertView;
    


    @Override
    public String getItem(int position) 
        return mItems[position];
    

    @Override
    public long getItemId(int position) 
        return 0;
    

    @Override
    public int getCount() 
        return mItems.length;
    

但是在使用ViewHolder模式时仍然没有找到问题的原因。如果有人找到原因，请告诉我。

【参考方案2】：

我正在递归调用onBackPressed()，这导致了***Error。

【讨论】：

类似的问题。谢谢。

【参考方案3】：

查找错误的最佳方法是在您的代码中使用大量logcat 并找到logcat 未显示的位置。 但是您可以尝试像这样更改您的代码：

删除 MyAdapter 构造函数中的inflater = LayoutInflater.from(context);

将它移动到getview 方法中，如下所示：

if (convertView == null) 
    LayoutInflater inflater = ((Activity) context).getLayoutInflater();
    convertView=inflater.inflate(R.layout.selectable_text_layout, null,false);</br>
    viewHolder = new ViewHolder(convertView);
    convertView.setTag(viewHolder);

【讨论】：

感谢您的回复。这不是实际问题。虽然我试过了但是问题还是没有解决。

调用 notifyDatasetChanged() 时出错，但找不到问题。

如果您发表评论会发生什么：myAdapter.notifyDataSetChanged();？第一个解决方案：替换 myAdapter.notifyDataSetChanged();到 ((MyAdapter)listView.getAdapter()).notifyDataSetChanged();如果它不起作用：尝试第二种解决方案：runOnUIThread(new Runnable() myAdapter.notifyDataSetChanged(); )

【参考方案4】：

列表滚动的迭代次数过多会产生此错误。避免这种情况...

【参考方案5】：

我的 log.i 语句太多，其中 gson 用于将数组转换为字符串以进行日志记录。当我删除所有日志时，***Error 消失了。
