融云即时通讯SDK集成 -- 定制UI(二) ——增加自定义表情库
背景:
最近公司新上的app要加上即时通讯的性能, 本人疾速实现一个当然是不可能的了(我的项目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有余.最初点兵点将,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：https://www.rongcloud.cn/
文档：https://docs.rongcloud.cn/v4
这个工作当然还是落在我的头上. 我是应用的他们家的带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都须要开发者自定实现, 带UI的sdk封装了一些根本的界面,例如会话列表, 和他人聊天的会话界面.)当然这些曾经集成了UI的sdk并不能齐全满足一个产品的需要, 所以这篇文章跟大家讲下如何增加一套自定义的表情包.
成果如下哈:
尽管这里有点难看了哈哈, 不过是为了给大家展现办法嘛, 就不论那么多了. 能够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, 间接就加在这里了. 一个可恶的小猪猪????哈哈哈.
增加步骤
须要改变的有这么几个类:
AndroidEmoji: 管制emoji图标资源, 编码, 以及相应展现的类
RongExtension: 会话界面除去聊天气泡与title bar的整个下方输出区域
IEmoticonTab: 表情tab
DefaultExtensionModule: 表情tab的下层控件.
对于AndroidEmoji这个类, 能够间接照抄, 把资源文件替换成本人筹备好的图标, 以及编码/形容

@Override public List<IEmoticonTab> getEmoticonTabs() { List<IEmoticonTab> emoticonTabs = super.getEmoticonTabs(); MyEmoticonTab myEmoticonTab =new MyEmoticonTab(); myEmoticonTab.setOnItemClickListener(new IEmojiItemClickListener() { @Override public void onEmojiClick(String emoji) { EditText editText = MyExtensionModule.this.mEditText; if (editText != null) { int start = editText.getSelectionStart(); editText.getText().insert(start, emoji); } } @Override public 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, 而后获取到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; @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { this.start = start; this.count = count; } @Override public void afterTextChanged(Editable s) { // 这块的测验规定是纯emoji的， 加其余表情的话间接给他去掉， 或者本人写规定。// 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, 就功败垂成啦. 增加好了一套属于本人的表情包!
