我有一个ListVIEw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.但是在点击另一个项目时我得到的是StackOverFlowError.
下面是我的代码示例.如果我有任何错误,请告诉我.

编辑：
我在ListVIEw#onItemClickListener中调用notifyDatasetChanged时遇到问题.
解决方法:
最后我得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.如果有人找到原因让我知道.
总结以上是内存溢出为你收集整理的android – java.lang.StackOverflowError：堆栈大小为8MB,同时在ListView适配器中启用/禁用TextView#setTextIsSelectable全部内容，希望文章能够帮你解决android – java.lang.StackOverflowError：堆栈大小为8MB,同时在ListView适配器中启用/禁用TextView#setTextIsSelectable所遇到的程序开发问题。
