只是某个时候回来回答了在这里本应帮助你，问笔者也提到库太 – Veer3383

没有具体的api可用于实现和发送emojis。您可以使用ImageSpan对象实现此目的。 TextViews和EditTexts使用Spanned/Spannable对象来存储输入的文本内容，而不仅仅是Java字符串。在这些Spanned/Spannable对象上，您可以为文本上的部分定义跨度，以修改这些部分显示的方式。所以你可以显示图像来代替某些部分。

检查docs:

另外，我发现一个blog，它可能对你有所帮助。

感谢好吧，我会检查 –

如果信息对您有帮助，请立即行动并接受答案。 :) –

This Library是您需要实施的所有Emojicons。请不要忘记分别将TextView和EditText更改为本图书馆的EmojiconTextView和EmojiconEditText。

希望这会有所帮助。

谢谢我可以如何在我的项目中添加这些库，因为我正在使用android studio –

下载此库并将其作为模块导入到Android Studio中。然后在你的项目的build.gradle文件，添加依赖这样的.. '{依赖编译项目（“：ImportedProjectName”） }' – Mann

它而进口模块，它是显示错误 - ：指定gradle这个或Android的位置Eclipse项目 –

您需要在上传前编码表情符号。这样你编码的表情符号UTF代码

try { 
       String mystring = URLEncoder.encode(strComments, HTTP.UTF_8); 
       param.add(new BasicNameValuePair("comment", mystring)); 

      } catch (UnsupportedEncodingException e) { 
       e.printStackTrace(); 
      }

解码

enter code here 


try { 
      String Title = URLDecoder.decode(comment, "UTF-8"); 
      holder.tvComment.setText(Title); 
     } catch (UnsupportedEncodingException e) { 
      e.printStackTrace(); 
     }
