EaseUI
實際工作過程中，我們是用不了太多東西的，如果只是集成個im最多用到的就是聊天列表和聊天頁面。
我們來看重頭戲EaseUI這個庫。
官方文檔
其實官方的WiKi已經介紹的特別詳細了。官方EaseUI文檔
我們來看Demo
// start chat acitivity
Intent intent = new Intent(getActivity(), ChatActivity.class);
if(conversation.isGroup()){
if(conversation.getType() == EMConversationType.ChatRoom){
// it's group chat
intent.putExtra(Constant.EXTRA_CHAT_TYPE, Constant.CHATTYPE_CHATROOM);
}else{
intent.putExtra(Constant.EXTRA_CHAT_TYPE, Constant.CHATTYPE_GROUP);
}
}
// it's single chat
intent.putExtra(Constant.EXTRA_USER_ID, username);
startActivity(intent);
ChatActivity
我們來看看ChatActivity

/**

public class ChatActivity extends BaseActivity{
public static ChatActivity activityInstance;

String toChatUsername;
?
@Override
protected void onCreate(Bundle arg0) {
super.onCreate(arg0);
setContentView(R.layout.em_activity_chat);
activityInstance = this;
//get user id or group id
toChatUsername = getIntent().getExtras().getString("userId");
//use EaseChatFratFragment
chatFragment = new ChatFragment();
//pass parameters to chat fragment
chatFragment.setArguments(getIntent().getExtras());
getSupportFragmentManager().beginTransaction().add(R.id.container, chatFragment).commit();
}
@Override

}
@Override

// make sure only one chat activity is opened
String username = intent.getStringExtra("userId");
if (toChatUsername.equals(username))
super.onNewIntent(intent);
else {
finish();
startActivity(intent);
}
?
}
@Override
public void onBackPressed() {
chatFragment.onBackPressed();
if (EasyUtils.isSingleActivity(this)) {
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
}
}
public String getToChatUsername(){
return toChatUsername;
}
?
@Override public void onRequestPermissionsResult(int requestCode, @NonNull String permissions,

}
}
官方文檔是這么說的
封裝EaseChatFragment的ChatFragment
那么Demo中是做了一層封裝的。

由于業務未涉及，暫不作分析。
總結及其他
其實正常集成，按照于海同學所說也就半天時間，這是因為的確環信的SDK使用起來比較方便。
通過大致的閱讀代碼，環信的Demo代碼寫的還是很不錯的，功能齊全，注釋完整。值得學習和研究。
寫在最后
多學習，多積累，多輸出。！
附:最近兩天實際工作采用環信SDK的開發詳案
