EaseUI

实际工作过程中，我们是用不了太多东西的，如果只是集成个im最多用到的就是聊天列表和聊天页面。

我们来看重头戏EaseUI这个库。

官方文档

其实官方的WiKi已经介绍的特别详细了。官方EaseUI文档

我们来看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

我们来看看ChatActivity

package com.hyphenate.chatuidemo.ui;

import android.content.Intent;

import android.os.Bundle;

import android.support.annotation.NonNull;

import com.hyphenate.chatuidemo.R;

import com.hyphenate.chatuidemo.runtimepermissions.PermissionsManager;

import com.hyphenate.easeui.ui.EaseChatFragment;

import com.hyphenate.util.EasyUtils;

/**

* chat activity，EaseChatFragment was used {@link #EaseChatFragment}

public class ChatActivity extends BaseActivity{

public static ChatActivity activityInstance;

private EaseChatFragment chatFragment;

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

protected void onDestroy() {

super.onDestroy();

activityInstance = null;

}

@Override

protected void onNewIntent(Intent intent) {

// 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,

@NonNull int grantResults) {

PermissionsManager.getInstance().notifyPermissionsChange(permissions, grantResults);

}

官方文档是这么说的

封装EaseChatFragment的ChatFragment

那么Demo中是做了一层封装的。
