我有ListView
的活动。在每个列表项中显示TextView
。使用这些方法切换所选位置的属性EditText#setTextIsSelectable
,EditText#setEllipsize
& EditText#setSingleLine
。点击第1项工作正常。但是点击另一个项目我正在StackOverFlowError
。
以下是我的代码示例。如果我有任何错误,请告诉我。

提前致谢。
编辑:
在notifyDatasetChanged
中调用ListView#onItemClickListener
时,我遇到了问题。
答案 0 :(得分:3)
最后,我得到了解决问题的方法。我在ViewHolder
中删除了MyAdapter
模式,如
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。如果有人找到原因让我知道。
答案 1 :(得分:1)
我递归地打电话给onBackPressed()
,这给了我StackOverFlowError
。
答案 2 :(得分:0)
查找错误的最佳方法是在代码中使用大量logcat
并找到logcat
未显示的位置。
但您可以尝试更改代码:
inflater = LayoutInflater.from(context);
按照getview
方法移动它:
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);
}
答案 3 :(得分:0)
对于列表滚动的大部分迭代都会产生此错误。避免...
答案 4 :(得分:0)
我的 log.i 语句太多了,其中 gson 用于将数组转换为字符串以进行记录。当我删除所有日志时,stackOverflowError 消失了。
