背景:
最近公司新上的app要加上即时通讯的功能, 自己快速实现一个当然是不可能的了(项目deadline也顶不住哇).就从各家成熟的SDK厂商选来选去的, 各有各的好也各有各的不足.最后点兵点将,选了融云家的SDK(老板说了算hhhh).
他家的官网和文档地址:
官网：/
文档：/v4
这个任务当然还是落在我的头上. 我是使用的他们家的带UI的sdk,(他们家有带UI和不带UI的两种sdk, 不带UI的sdk就是只有即时通讯能力, 所有的UI都需要开发者自定实现, 带UI的sdk封装了一些基本的界面,例如会话列表, 和别人聊天的会话界面.)当然这些已经集成了UI的sdk并不能完全满足一个产品的需求, 所以这篇文章跟大家讲下如何添加一套自定义的表情包.
效果如下哈:
虽然这里有点难看了哈哈, 不过是为了给大家展示方法嘛, 就不管那么多了. 可以看到底下除了默认的emoji的表情包, 还多了一个tab, 我是从QQ表情搞了一套, 直接就加在这里了. 一个可爱的小猪猪🐷哈哈哈.
添加步骤
需要改动的有这么几个类:
AndroidEmoji: 控制emoji图标资源, 编码, 以及相应展示的类
RongExtension: 会话界面除去聊天气泡与title bar的整个下方输入区域
IEmoticonTab: 表情tab
DefaultExtensionModule: 表情tab的上层控件.
对于AndroidEmoji这个类, 可以直接照抄, 把资源文件替换成自己准备好的图标, 以及编码/描述

集成DefaultExtensionModule, 实现MyExtensionModule, 重写getEmoticonTabs()方法, 为每个图标设置监听.
@Overridepublic List<IEmoticonTab> getEmoticonTabs() {List<IEmoticonTab> emoticonTabs = super.getEmoticonTabs();MyEmoticonTab myEmoticonTab =new MyEmoticonTab();myEmoticonTab.setOnItemClickListener(new IEmojiItemClickListener() {@Overridepublic void onEmojiClick(String emoji) {EditText editText = MyExtensionModule.this.mEditText;if (editText != null) {int start = editText.getSelectionStart();editText.getText().insert(start, emoji);}}@Overridepublic void onDeleteClick() {EditText editText = MyExtensionModule.this.mEditText;if (editText != null) {editText.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DEL));}}});emoticonTabs.add(myEmoticonTab);return emoticonTabs;}
继承RongExtension, 实现MyRongExtension, 然后获取到editText, 为其设置监听, 代码如下:
public class MyRongExtension extends RongExtension {EditText mEditText;public MyRongExtension(Context context) {super(context);tryAddTextChangedAction();}public MyRongExtension(Context context, AttributeSet attrs) {super(context, attrs);tryAddTextChangedAction();}private void tryAddTextChangedAction() {mEditText = getInputEditText();TextWatcher textWatcher = new TextWatcher() {private int start;private int count;@Overridepublic void beforeTextChanged(CharSequence s, int start, int count, int after) {}@Overridepublic void onTextChanged(CharSequence s, int start, int before, int count) {this.start = start;this.count = count;}@Overridepublic void afterTextChanged(Editable s) {// 这块的检验规则是纯emoji的， 加其他表情的话直接给他去掉， 或者自己写规则。//if (QQEmoji.isQQEmoji(s.subSequence(start, start + count).toString())) {mEditText.removeTextChangedListener(this);String resultStr = QQEmoji.replaceEmojiWithText(s.toString());mEditText.setText(QQEmoji.ensure(resultStr), TextView.BufferType.SPANNABLE);mEditText.setSelection(mEditText.getText().length());mEditText.addTextChangedListener(this);//}}};mEditText.addTextChangedListener(textWatcher);}}
这样一来, 就大功告成啦. 添加好了一套属于自己的表情包!
