Android聊天應用程序表情符號的問題

我正在開發Android聊天應用程序。現在我想在聊天模塊中發送表情符號。我如何在聊天應用程序中實現表情符號？請指導我這個應用程序。如果有這個應用程序的任何API，那麼也建議我。謝謝Android聊天應用程序表情符號的問題

只是某個時候回來回答了在這裏本應幫助你，問筆者也提到庫太 – Veer3383

沒有具體的api可用於實現和發送emojis。您可以使用ImageSpan對象實現此目的。 TextViews和EditTexts使用Spanned/Spannable對象來存儲輸入的文本內容，而不僅僅是Java字符串。在這些Spanned/Spannable對象上，您可以爲文本上的部分定義跨度，以修改這些部分顯示的方式。所以你可以顯示圖像來代替某些部分。

檢查docs:

另外，我發現一個blog，它可能對你有所幫助。

感謝好吧，我會檢查 –

如果信息對您有幫助，請立即行動並接受答案。 :) –

This Library是您需要實施的所有Emojicons。請不要忘記分別將TextView和EditText更改爲本圖書館的EmojiconTextView和EmojiconEditText。

希望這會有所幫助。

謝謝我可以如何在我的項目中添加這些庫，因爲我正在使用android studio –

下載此庫並將其作爲模塊導入到Android Studio中。然後在你的項目的build.gradle文件，添加依賴這樣的.. '{依賴編譯項目（「：ImportedProjectName」） }' – Mann

它而進口模塊，它是顯示錯誤 - ：指定gradle這個或Android的位置Eclipse項目 –

您需要在上傳前編碼表情符號。這樣你編碼的表情符號UTF代碼

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

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

解碼

enter code here 


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