java - 由于特殊字符，从 Web 服务器检索到的数据无法显示

Question

由于特殊字符，我从网络服务器检索到的数据没有显示在我的 ListView 中。对于我检索的其中一个示例，数据是: ****要共享的两种策略

A) 公司选择

**在这种情况下，它只显示到“要共享的两种策略”。我可以知道对我有什么建议吗？我尝试了正则表达式，但不确定如何在我的文件中实现它。这是我的编码:

                // getting values from selected ListItem
                String title = ((TextView) view.findViewById(R.id.title))
                        .getText().toString();

                HashMap<String, String> description = menuItems.get(position);

                // Starting new intent
                Intent in = new Intent(getApplicationContext(),
                        SingleMenuItemActivity.class);
                in.putExtra(KEY_TITLE, title);
                in.putExtra(KEY_DESC, description);

                startActivity(in);

            }
        });
    }
}

关于如何解决这个问题有什么建议吗？

试试 spannable string builder。它将保留您的字符串的内容和标记，您将能够显示这些特殊字符。

http://developer.android.com/reference/android/text/SpannableStringBuilder.html

例子:

SpannableStringBuilder stringBuilder = new SpannableStringBuilder();
stringBuilder.append(text);

现在在你的 ListView 文本中就这样放

textView.setText(stringBuilder);
