java.lang.StackOverflowError：在ListView适配器中启用/禁用TextView＃setTextIsSelectable时，堆栈大小为8MB

sho*_*han 5 android listview textview

我有一个活动ListView。TextView在每个列表项中显示。使用这些方法切换选定位置的属性EditText#setTextIsSelectable，EditText#setEllipsize＆EditText#setSingleLine。单击第一个项目效果很好。但是当我点击另一个项目时，我得到了StackOverFlowError。

下面是我的代码示例。如果我有任何错误，请让我知道。

提前致谢。

编辑：

打电话时，我得到的问题notifyDatasetChanged在 ListView#onItemClickListener。

最后我得到了我的问题的解决方案。我删除了类似的ViewHolder图案MyAdapter

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;
    }
}

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