如何访问在Runnable类内部但在run方法外部运行Runnable的线程？

我想调用Thread.currentThread（）。interrupt（）; 下面代码中的方法导致中断，并且Logcat打印输出，Log.e（“”，“ interrupted” + e.toString（））; 但是，为此，我需要从interruptThread（）方法内部访问运行runnable的线程。它是StopIt类的成员类。

但是，在interruptThread（）方法中运行的所有代码都在主UI线程上运行。因此，当我调用Thread.currentThread（）。interrupt（）时，将在主UI线程上调用它。

我如何从interruptThread（）方法内部访问正在运行Runnable的辅助线程或后台线程？

public class StopIt implements Runnable {

  @Override
  public void run() {

     try {

     Thread.sleep(10000);

     } catch (InterruptedException e) {

        // this Log message should print out if working correctly
        // when the interruptThread() method below is called on this Thread
        Log.e("", "interrupted " + e.toString());

     }

 }

 public void interruptThread() {

     // determines which thread this code is running on,
     // UI or other thread
     // returns true if the thread is the UI thread
     if(Looper.myLooper() == Looper.getMainLooper()) {

     Log.e("Thread check", "MAIN UI THREAD"); // <-- RESULT OF TEST

   } else {

     Log.e("Thread check", "other thread NOT main UI thread");

   }

     // calls interrupt on the main UI thread not the Runnable
     // how to get this to interrupt the Runnable thread above?
     Thread.currentThread().interrupt();

 }

}
