片段切换期间onResume（）的替代方法

Question

当我们在片段之间切换多次时，将不会调用onResume()方法。那么，有没有更好的处理恢复操作的方法呢？

代码如下：

步骤：1

创建接口：

public interface YourFragmentInterface {
    void fragmentBecameVisible();
}

mViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(final int position, final float v, final int i2) {
        }

        @Override
        public void onPageSelected(final int position) {
            YourFragmentInterface fragment = (YourFragmentInterface) mPagerAdapter.instantiateItem(mViewPager, position);
            if (fragment != null) {
                fragment.fragmentBecameVisible();
            } 
        }

        @Override
        public void onPageScrollStateChanged(final int position) {
        }
    });

public class yourActivity extends SherlockFragment implements YourFragmentInterface{
    @Override
    public void fragmentBecameVisible() {
          System.out.println("TestFragment");
    }
}
