getSupportFragmentManager.getFra

公司项目的targetSdkVersion版本升级到25以后，getSupportFragmentManager.getFragment()被IDE警告不推荐使用了

解决方案代码如下

 List<WeakReference<Fragment>> fragList = new 
                                        ArrayList<WeakReference<Fragment>>();

@Override
public void onAttachFragment (Fragment fragment) {
    fragList.add(new WeakReference(fragment));
}

public List<Fragment> getActiveFragments() {
     ArrayList<Fragment> ret = new ArrayList<Fragment>();
     for(WeakReference<Fragment> ref : fragList) {
     Fragment f = ref.get();
     if(f != null) {
         if(f.isVisible()) {
             ret.add(f);
         }
     }
     }
     return ret;
}
