问题描述

我正在与ListView一起活动.在每个列表项中显示TextView.使用这些方法EditText#setTextIsSelectable，EditText#setEllipsize&切换所选位置的属性. 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，我会得到StackOverFlowError.

I have an activity with ListView . Displaying the TextView in each list item. Switching the properties of selected position using these methods EditText#setTextIsSelectable , EditText#setEllipsize & EditText#setSingleLine . clicking on 1st item is working good. But while clicking on another item I'm getting StackOverFlowError.

下面是我的代码示例.如果我有任何错误，请告诉我.

先谢谢了.

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

推荐答案

最后，我为我的问题找到了解决方案.我像一样删除了MyAdapter中的ViewHolder模式

Finally I got the solution for my problem. I removed ViewHolder pattern in MyAdapter like

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模式时仍然找不到问题的原因.如果有人找到原因，请告诉我.

But still didn't find the the reason for the problem when using ViewHolder pattern.If anybody find the reason let me know.
