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

集成 DefaultExtensionModule, 实现 MyExtensionModule, 重写 getEmoticonTabs()办法, 为每个图标设置监听.
@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!
