kotlin简单实现AIDL进程间通信

Posted 2022-11-24 zhangjin1120

上一篇：java简单实现AIDL进程通信，是java版的，现在写一篇kotlin的。

具体步骤和上篇文章一样，我直接贴代码。

• 服务端NameService

class NameService : Service() 

    override fun onBind(intent: Intent): IBinder? 
        return ServiceStub()
    

    class ServiceStub : IGetNameInterface.Stub()
        override fun getInfo(): String 
            return "zhangjin"
        
    

• 客户端MainActivity

class MainActivity : AppCompatActivity() 
    var mGetNameService: IGetNameInterface? = null

    override fun onCreate(savedInstanceState: Bundle?) 
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        var intent = Intent()
        intent.component =
            ComponentName("com.exp.kotlinservice", "com.exp.kotlinservice.NameService")
        var connection = object : ServiceConnection 
            override fun onServiceConnected(name: ComponentName?, service: IBinder?) 
                Log.e(TAG, "onServiceConnected: ")
                try 
                    mGetNameService = IGetNameInterface.Stub.asInterface(service)
                    var tv: TextView = findViewById(R.id.tv)
                    tv.text = mGetNameService?.info
                 catch (e: Exception) 
                    Log.e(TAG, "exception: " + e.message)
                
            

            override fun onServiceDisconnected(name: ComponentName?) 
                Log.e(TAG, "onServiceDisconnected: ")
            
        

        bindService(intent, connection, Context.BIND_AUTO_CREATE)

    

    companion object 
        private const val TAG = "MainActivity"
