                        break;
                    //滑动
                    case TouchEvent.POINT_MOVE:
                        btn2.setText("滑动");
                        break;

                }
                return true;
            }
        });


    }

    @Override
    public void onActive() {
        super.onActive();
    }

    @Override
    public void onForeground(Intent intent) {
        super.onForeground(intent);
    }
}

这里记得修改为true

否则可能会只有按下事件
