Android 将表情符号转换为unicode
我需要发送一个包含文本以及表情符号的文本到服务器。我使用jsonparser类将其发送到服务器,但当我发送时,服务器端似乎包含unicode的问号instaed。我应该如何继续转换到unicode。请帮忙Android 将表情符号转换为unicode,android,json,unicode,emoji,Android,Json,Unicode,Emoji,我需要发送一个包含文本以及表情符号的文本到服务器。我使用jsonparser类将其发送到服务器,但当我发送时,服务器端似乎包含unicode的问号instaed。我应该如何继续转换到unicode。请帮忙 List<NameValuePair> params = new ArrayList<NameValuePair>(); Log.d("userstatus",userstatus); params.add(new Basi

我用文本和表情符号的“?”得到响应。请帮助。我得到了答案。要获得表情符号的unicode码:
StringEscapeUtils.escapeJava(<text>);
StringEscapeUtils.unescapeJava(<unicode_emoticon>);
StringEscapeUtils.escapeJava();
并将其解码回表情符号:
StringEscapeUtils.escapeJava(<text>);
StringEscapeUtils.unescapeJava(<unicode_emoticon>);
StringEscapeUtils.unescapeJava();
这是API标准吗
