我有一个 Activity ListView 。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 和 EditText#setSingleLine 。点击第一项效果很好。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。如果我做错了，请告诉我。

import android.app.Activity;

    private ListView listView;

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);//only ListView present in this layout
        listView = (ListView) findViewById(R.id.myList);

        final MyAdapter myAdapter = new MyAdapter(this, items);
        listView.setAdapter(myAdapter);
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            this.mSelectedPosition = mSelectedPosition;

                viewHolder = new ViewHolder(convertView);
                convertView.setTag(viewHolder);
            } else {
                viewHolder = (ViewHolder) convertView.getTag();
            }
            String item = getItem(position);

            viewHolder.selectableTV.setText(item);


            if (position == mSelectedPosition) {
                Log.d(TAG, "getView() called with: " + "position = [" + position + "], selected = " + true);

                viewHolder.selectableTV.setSingleLine(true);
                viewHolder.selectableTV.setEllipsize(TextUtils.TruncateAt.END);
            }
            return convertView;
        }


        @Override

            return mItems[position];
        }

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

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

        private class ViewHolder {
            public final TextView selectableTV;

            ViewHolder(View convertView) {
                selectableTV = (TextView) convertView.findViewById(R.id.selectableTextView);
            }
        }
    }
}

布局文件: selectable_text_layout.xml

<?xml version="1.0" encoding="utf-8"?>

提前致谢。

编辑:

在 ListView#onItemClickListener 中调用 notifyDatasetChanged 时出现问题。

最佳答案

我递归地调用了 onBackPressed()，这导致了我的 StackOverFlowError。

关于android - java.lang.StackOverflowError : stack size 8MB while Enabling/Disabling TextView#setTextIsSelectable in ListView Adapter 错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/37066986/
