37 | } 38 | 39 | @Override 40 | public void onSearchFinish(HashMap devices) { 41 | //搜索完成 42 | //devices为搜索到的所有设备，它的key为此设备的IP地址 43 | } 44 | }); 45 | ``` 46 | 47 | 48 | 设置是否可以被其他设备搜索 49 | ``` 50 | //设置可以被其他设备搜索 51 | LanCommManager.getSearcher().setCanBeSearched(true); 52 | 53 | //设置不能被其他设备搜索 54 | LanCommManager.getSearcher().setCanBeSearched(false); 55 | ``` 56 | 57 | 58 | 当前是否可以被其他设备搜索 59 | ``` 60 | boolean canBeSearch = LanCommManager.getSearcher().isCanBeSearched(); 61 | ``` 62 | 63 | ### 2.2 消息接收 64 | > 通过LanCommManager.getReceiver(); 您可以获取到LAN-COMM的消息接收器，通过接收器，可以接收到其他设备发送的广播消息和点对点消息，以及其他设备上下线的通知消息。 65 | 66 | 接收与不接收其他设备发送的广播消息和点对点消息 67 | ``` 68 | DataListener listener = new DataListener() { 69 | @Override 70 | public void onBroadcastArrive(CommData commData) { 71 | //接收到广播消息 72 | } 73 | 74 | @Override 75 | public void onCommandArrive(CommData commData) { 76 | //接收到点对点消息 77 | } 78 | }; 79 | //接收其他设备发送的广播消息和点对点消息 80 | LanCommManager.getReceiver().addDataListener(listener); 81 | 82 | //移除其他设备发送的广播消息和点对点消息的监听 83 | LanCommManager.getReceiver().removeDataListener(listener); 84 | ``` 85 | ### 2.3 广播消息 86 | > 通过LanCommManager.Broadcaster(); 您可以获取到LAN-COMM的广播器，通过广播器，可以给所有设备发送广播消息。 87 | 通过广播器发送的消息，可以在[2.2 消息接收]中的消息接收器中接收到发送的消息，自己发送的消息自己也是可以接收到的。 88 | 89 | 发送广播消息 90 | ``` 91 | LanCommManager.getBroadcaster().broadcast("Hello LAN-COMM".getBytes()); 92 | ``` 93 | 94 | ### 2.4 点对点消息 95 | > 通过LanCommManager.getCommunicator(); 您可以获取到LAN-COMM的点对点通讯器，可以给指定的设备发送消息。 96 | 发送的点对点消息可以在[2.2 消息接收]中的消息接收器中接收到发送的消息。 97 | 98 | 发送点对点消息 99 | ``` 100 | // 101 | Command command = new Command().setDestIp(device.getIp()) 102 | .setData("我点你了，哈哈~".getBytes()) 103 | .setCallback(new Command.Callback() { 104 | @Override 105 | public void onSuccess() { 106 | //发送成功 107 | Trace.d(TAG, "send success"); 108 | } 109 | 110 | @Override 111 | public void onError(int code) { 112 | //发送失败 113 | Trace.d(TAG, "onError() " + code); 114 | } 115 | 116 | @Override 117 | public void onReceived() { 118 | //对方已收到 119 | Trace.d(TAG, "对方已收到"); 120 | } 121 | }); 122 | 123 | LanCommManager.getCommunicator().sendCommand(command); 124 | ``` 125 | 126 | ### 3 Kotlin扩展函数 127 | 128 | #### 3.1 获取管理类 129 | ``` 130 | //获取广播器 131 | broadcaster 132 | 133 | //获取接收器 134 | receiver 135 | 136 | //获取搜索器 137 | searcher 138 | 139 | //获取点对点消息器 140 | communicator 141 | ``` 142 | #### 3.1 发送点对点消息 143 | ``` 144 | //发送点对点消息 145 | sendCommand{ 146 | destIp = "192.168.1.13" 147 | data = "我点你了，哈哈~".toByteArray() 148 | callback = object : Command.Callback { 149 | override fun onSuccess() { 150 | } 151 | 152 | override fun onReceived() { 153 | } 154 | 155 | override fun onError(code: Int) { 156 | } 157 | } 158 | } 159 | ``` -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | *.iml 3 | .gradle 4 | /.idea 5 | /local.properties 6 | .DS_Store -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 30 5 | buildToolsVersion "30.0.2" 6 | 7 | defaultConfig { 8 | applicationId "com.fighter.lancomm_demo" 9 | minSdkVersion 19 10 | targetSdkVersion 30 11 | versionCode 1 12 | versionName "1.0" 13 | 14 | testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" 15 | } 16 | 17 | buildTypes { 18 | release { 19 | minifyEnabled false 20 | proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' 21 | } 22 | } 23 | } 24 | 25 | dependencies { 26 | implementation fileTree(dir: "libs", include: ["*.jar"]) 27 | implementation 'androidx.appcompat:appcompat:1.2.0' 28 | implementation 'androidx.constraintlayout:constraintlayout:2.0.4' 29 | testImplementation 'junit:junit:4.12' 30 | androidTestImplementation 'androidx.test.ext:junit:1.1.2' 31 | androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0' 32 | 33 | implementation "androidx.recyclerview:recyclerview:1.1.0" 34 | implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" 35 | implementation 'androidx.core:core-ktx:1.3.2' 36 | implementation project(':lancomm-kt') 37 | } 38 | -------------------------------------------------------------------------------- /app/proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # Add project specific ProGuard rules here. 2 | # You can control the set of applied configuration files using the 3 | # proguardFiles setting in build.gradle. 4 | # 5 | # For more details, see 6 | # http://developer.android.com/guide/developing/tools/proguard.html 7 | 8 | # If your project uses WebView with JS, uncomment the following 9 | # and specify the fully qualified class name to the JavaScript interface 10 | # class: 11 | #-keepclassmembers class fqcn.of.javascript.interface.for.webview { 12 | # public *;
