1.配置EM
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.example.administrator.chatdemo"> <!--环信需要权限--><uses-permission android:name="android.permission.VIBRATE" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.RECORD_AUDIO" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><!--<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />--><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.GET_TASKS" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <applicationandroid:name=".common.MyApplication"android:allowBackup="true"android:icon="@mipmap/ic_launcher"android:label="@string/app_name"android:theme="@style/AppTheme"> <activityandroid:name=".activity.MainActivity"android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".activity.A1_RegisterActivity" /> <activity android:name=".activity.A2_LoginActivity" /> <activityandroid:name=".activity.A3_SendTextActivity"android:launchMode="singleInstance" /> <!--环信:START--><meta-dataandroid:name="EASEMOB_APPKEY"android:value="fishgas#chatdemo" /> <service android:name="com.easemob.chat.EMChatService" /><!--环信:END--></application> </manifest>
public class MyApplication extends Application {public static Context context;
@Overridepublic void onCreate() {super.onCreate();context = getApplicationContext();initEaseMob();initImageLoader();}
/** * 配置ImageLoader */private void initImageLoader() { DisplayImageOptions defaultOptions = new DisplayImageOptions .Builder() .showImageForEmptyUri(R.drawable.empty_photo) .showImageOnFail(R.drawable.empty_photo) .cacheInMemory(true) .cacheOnDisc(true) .build();ImageLoaderConfiguration config = new ImageLoaderConfiguration .Builder(getApplicationContext()) .defaultDisplayImageOptions(defaultOptions) .discCacheSize(50 * 1024 * 1024)//.discCacheFileCount(100)//缓存一百张图片.writeDebugLogs() .build();ImageLoader.getInstance().init(config);}
/** * 配置环信IM */private void initEaseMob() { EMChat.getInstance().init(getApplicationContext());}
}
2.常用方法，已封装成工具类（待补充……）
/*环信工具类*/public class EMUtil {
/** * EM注册账号*/public static void register(final Activity context, final String username, final String password) {new AsyncTask<String, Integer, String>() {@Overrideprotected String doInBackground(String... params) {// 调用sdk注册方法try { EMChatManager.getInstance().createAccountOnServer(username, password);//注册成功AbSharedUtil.putString(context, "username", username);AbSharedUtil.putString(context, "password", password);context.finish();showToastOnUI(context, "环信注册成功");} catch (EaseMobException e) {switch (e.getErrorCode()) {case EMError.NONETWORK_ERROR:showToastOnUI(context, "网络异常，请检查网络！"); break; case EMError.USER_ALREADY_EXISTS:showToastOnUI(context, "用户已存在！"); break; case EMError.UNAUTHORIZED:showToastOnUI(context, "注册失败，无权限！"); break; default:showToastOnUI(context, "注册失败: " + e.getMessage()); break;} }return null;} }.execute();}
/** * EM登录账号*/public static void login(final Activity context, final String username, final String password) {new AsyncTask<String, Integer, String>() {@Overrideprotected String doInBackground(String... params) { EMChatManager.getInstance().login(username, password, new EMCallBack() {//回调@Overridepublic void onSuccess() {context.runOnUiThread(new Runnable() {public void run() { EMGroupManager.getInstance().loadAllGroups();EMChatManager.getInstance().loadAllConversations();context.finish();showToastOnUI(context, "环信登录成功");} });}
@Overridepublic void onProgress(int progress, String status) {
}
@Overridepublic void onError(int code, String message) { } }); return null;} }.execute();}
/** * EM动态注册广播，接受广播*/public static void registerEMReceiver(Activity context) { EMReceiver msgReceiver = new EMReceiver();IntentFilter intentFilter = new IntentFilter(EMChatManager.getInstance().getNewMessageBroadcastAction());intentFilter.setPriority(3);context.registerReceiver(msgReceiver, intentFilter);}
/** * EM发送文本消息*/public static void sendText(Activity context, String friendStr, String inputStr, final MyEMCallBack myEMCallBack) { LogUtil.e("friendStr=" + friendStr + "\tinputStr=" + inputStr);String username = AbSharedUtil.getString(context, "username", "");String password = AbSharedUtil.getString(context, "password", "");//获取到与聊天人的会话对象。参数username为聊天人的userid或者groupid，后文中的username皆是如此EMConversation conversation = EMChatManager.getInstance().getConversation(username);//创建一条文本消息final EMMessage message = EMMessage.createSendMessage(EMMessage.Type.TXT);//如果是群聊，设置chattype,默认是单聊message.setChatType(EMMessage.ChatType.Chat);//设置消息bodyTextMessageBody txtBody = new TextMessageBody(inputStr);message.addBody(txtBody);//设置接收人message.setReceipt(friendStr);//把消息加入到此会话对象中conversation.addMessage(message);//发送消息，并传入回调监听EMChatManager.getInstance().sendMessage(message, new EMCallBack() {@Overridepublic void onSuccess() { LogUtil.e("");myEMCallBack.onSuccess(message);}
@Overridepublic void onError(int i, String s) {myEMCallBack.onError(i, s);}
@Overridepublic void onProgress(int i, String s) { } });}
/** * 对EM回调进行改造，成功的方法中多传一个EMMessage对象*/public interface MyEMCallBack {void onSuccess(EMMessage message); void onError(int var1, String var2);}
/** * 在分线程中显示Toast */public static void showToastOnUI(final Activity context, final CharSequence message) { context.runOnUiThread(new Runnable() {@Overridepublic void run() { Looper.getMainLooper();LogUtil.s(message);} });}
}
3.接受消息的广播
public class EMReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) { abortBroadcast();// 注销广播,避免重复接收String msgId = intent.getStringExtra("msgid");// 消息id（每条消息都会生成唯一的一个id，目前是SDK生成）String username = intent.getStringExtra("from");//发送方EMMessage message = EMChatManager.getInstance().getMessage(msgId); // 收到这个广播的时候，message已经在db和内存里了，可以通过id获取mesage对象EMConversation conversation = EMChatManager.getInstance().getConversation(username);
LogUtil.e("接受到环信的消息：message=" + JSON.toJSONString(message));
Intent it = new Intent(context, A3_SendTextActivity.class);Bundle bundle = new Bundle();bundle.putParcelable("message", message);it.putExtras(bundle);it.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);context.startActivity(it);
}}
4.聊天界面
//发送消息public class A3_SendTextActivity extends Activity { Context context = A3_SendTextActivity.this;
@InjectView(R.id.et_friend) EditText friend;@InjectView(R.id.et_input) EditText input;
@InjectView(R.id.listview) ListView listView;ChatAdapter adapter;List<EMMessage> data = new ArrayList<EMMessage>();
@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_sendtext);ButterKnife.inject(this);initListView();EMUtil.registerEMReceiver(A3_SendTextActivity.this);}
@OnClick(R.id.send)public void doSend(View v) { String friendStr = friend.getText().toString().trim();String inputStr = input.getText().toString().trim();
if (TextUtils.isEmpty(friendStr) || TextUtils.isEmpty(inputStr)) { LogUtil.s("请输入完整信息！"); return;} EMUtil.sendText(A3_SendTextActivity.this, friendStr, inputStr, new EMUtil.MyEMCallBack() {@Overridepublic void onSuccess(EMMessage message) { LogUtil.e("");addEMMessageToListView(message);}
@Overridepublic void onError(int var1, String var2) {
} });}
@OnClick(R.id.getmsg)public void doGetMSg(View v) { String friendStr = friend.getText().toString().trim(); if (TextUtils.isEmpty(friendStr)) { LogUtil.s("请输入完整信息！"); return;} getMsgList(friendStr);}
/** * 初始化聊天消息列表*/private void initListView() {adapter = new ChatAdapter(context);listView.setAdapter(adapter);}
/** * 从广播进入聊天界面*/@Overrideprotected void onNewIntent(Intent intent) { Bundle bun = intent.getExtras();EMMessage message = bun.getParcelable("message");addEMMessageToListView(message);}
/** * 获取与好友的聊天记录*/private void getMsgList(String friendStr) { EMConversation conversation = EMChatManager.getInstance().getConversation(friendStr);//获取此会话的所有消息List<EMMessage> messages = conversation.getAllMessages();data = messages;adapter.setData(data);adapter.notifyDataSetChanged();listView.setSelection(data.size());}
/** * 将接受的消息添加进listview */private void addEMMessageToListView(EMMessage msg) {data.add(msg);adapter.setData(data);adapter.notifyDataSetChanged();listView.setSelection(data.size());}
}
