Android开发中怎么实现一个长按Button键连续响应功能

public class LongClickButton extends Button {    private LongClickRepeatListener repeatListener;    private long intervalTime;  private MyHandler handler;  public LongClickButton(Context context) {    super(context);    init();  }  public LongClickButton(Context context, AttributeSet attrs) {    super(context, attrs);    init();  }  public LongClickButton(Context context, AttributeSet attrs, int defStyleAttr) {    super(context, attrs, defStyleAttr);    init();  }    private void init() {    handler = new MyHandler(this);    setOnLongClickListener(new OnLongClickListener() {      @Override      public boolean onLongClick(View v) {        new Thread(new LongClickThread()).start();        return true;      }    });  }    private class LongClickThread implements Runnable {    private int num;    @Override    public void run() {      while (LongClickButton.this.isPressed()) {        num++;        if (num % 5 == 0) {          handler.sendEmptyMessage(1);        }        SystemClock.sleep(intervalTime / 5);      }    }  }    private static class MyHandler extends Handler {    private WeakReference<LongClickButton> ref;    MyHandler(LongClickButton button) {      ref = new WeakReference<>(button);    }    @Override    public void handleMessage(Message msg) {      super.handleMessage(msg);      LongClickButton button = ref.get();      if (button != null && button.repeatListener != null) {        button.repeatListener.repeatAction();      }    }  }    public void setLongClickRepeatListener(LongClickRepeatListener listener, long intervalTime) {    this.repeatListener = listener;    this.intervalTime = intervalTime;  }    public void setLongClickRepeatListener(LongClickRepeatListener listener) {    setLongClickRepeatListener(listener, 100);  }  public interface LongClickRepeatListener {    void repeatAction();  }}
