要么编写一个实现Runnable的类，并在适当定义的构造函数中传递所需的任何内容，要么编写一个使用适当定义的构造函数来扩展Thread的类，该构造函数使用适当的参数调用super()。

Android专用

为了回调的目的，我通常使用输入参数实现自己的泛型Runnable:

public interface Runnable<TResult> {
    void run(TResult result);
}

用法很简单:

myManager.doCallbackOperation(new Runnable<MyResult>() {
    @Override
    public void run(MyResult result) {
        // do something with the result
    }
});

在经理:

public void doCallbackOperation(Runnable<MyResult> runnable) {
    new AsyncTask<Void, Void, MyResult>() {
        @Override
        protected MyResult doInBackground(Void... params) {
            // do background operation
            return new MyResult(); // return resulting object
        }

        @Override
        protected void onPostExecute(MyResult result) {
            // execute runnable passing the result when operation has finished
            runnable.run(result);
        }
    }.execute();
}

从Java 8开始，您可以使用lambda来捕获有效的final参数。例如:

final String param1 = "First param";
final int param2 = 2;
new Thread(() -> {
    // Do whatever you want here: param1 and param2 are in-scope!
    System.out.println(param1);
    System.out.println(param2);
}).start();

参数通过start()和run()方法传递:

// Tester
public static void main(String... args) throws Exception {
    ThreadType2 t = new ThreadType2(new RunnableType2(){
        public void run(Object object) {
            System.out.println("Parameter="+object);
        }});
    t.start("the parameter");
}

// New class 1 of 2
public class ThreadType2 {
    final private Thread thread;
    private Object objectIn = null;
    ThreadType2(final RunnableType2 runnableType2) {
        thread = new Thread(new Runnable() {
            public void run() {
                runnableType2.run(objectIn);
            }});
    }
    public void start(final Object object) {
        this.objectIn = object;
        thread.start();
    }
    // If you want to do things like setDaemon(true); 
    public Thread getThread() {
        return thread;
    }
}

// New class 2 of 2
public interface RunnableType2 {
    public void run(Object object);
}

有一种将参数传递到可运行程序的简单方法。 代码:

public void Function(final type variable) {
    Runnable runnable = new Runnable() {
        public void run() {
            //Code adding here...
        }
    };
    new Thread(runnable).start();
}

你需要在构造函数中将参数传递给Runnable对象:

public class MyRunnable implements Runnable {

   public MyRunnable(Object parameter) {
       // store parameter for later user
   }

   public void run() {
   }
}

并这样调用它:

Runnable r = new MyRunnable(param_value);
new Thread(r).start();
