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();

通过Runnable或Thread类的构造函数

class MyThread extends Thread {

    private String to;

    public MyThread(String to) {
        this.to = to;
    }

    @Override
    public void run() {
        System.out.println("hello " + to);
    }
}

public static void main(String[] args) {
    new MyThread("world!").start();
}

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();

这个答案来得很晚，但也许有人会觉得它有用。它是关于如何在不声明命名类的情况下将参数传递给Runnable(对于内联程序来说很方便):

    String someValue = "Just a demo, really...";

    new Thread(new Runnable() {
        private String myParam;

        public Runnable init(String myParam) {
            this.myParam = myParam;
            return this;
        }

        @Override
        public void run() {
            System.out.println("This is called from another thread.");
            System.out.println(this.myParam);
        }
    }.init(someValue)).start();

当然，您可以将start的执行推迟到某个更方便或合适的时刻。这取决于你init方法的签名(所以它可能需要更多和/或不同的参数)，当然甚至它的名字，但基本上你得到了一个想法。

事实上，还有另一种将参数传递给匿名类的方法，即使用初始化块。考虑一下:

    String someValue = "Another demo, no serious thing...";
    int anotherValue = 42;

    new Thread(new Runnable() {
        private String myParam;
        private int myOtherParam;
        // instance initializer
        {
            this.myParam = someValue;
            this.myOtherParam = anotherValue;
        }

        @Override
        public void run() {
            System.out.println("This comes from another thread.");
            System.out.println(this.myParam + ", " + this.myOtherParam);
        }
    }).start();

所有都发生在初始化程序块内部。

要创建线程，通常需要创建自己的Runnable实现。在该类的构造函数中将参数传递给线程。

class MyThread implements Runnable{
   private int a;
   private String b;
   private double c;

   public MyThread(int a, String b, double c){
      this.a = a;
      this.b = b;
      this.c = c;
   }

   public void run(){
      doSomething(a, b, c);
   }
}

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();
}
