Fragment跳轉，同時實現Fragment，fragment跳轉

Fragment跳轉，同時實現Fragment，fragment跳轉

在使用getSupportFragmentManager().findFragmentByTag（tag）無法找到，返回為空白，原因由於咋replace（）時必須要將fragment放入到返回棧中。

保證調用以下方法：ft.addToBackStack(tag);

/**
* Example of starting nested fragment from another fragment: Fragment
* newFragment = ManagerTagFragment.newInstance(tag.getMac()); TagsActivity
* tAct = (TagsActivity)getActivity(); tAct.pushFragments(newFragment, true,
* true, null);
* --------------------------------------------------------------
* fragement切換
* 
* @param fragment
*            要切換的介面
* @param shouldAnimate
*            是否需要動畫
* @param addToBackStack
*            是否添加到返回棧中（只有添加到返回棧中的介面
*            才可以使用getSupportFragmentManager().findFragmentByTag
*            (setting)）找到對應的介面(使用返回鍵返回後，棧中緩衝的介面回收)
* @param tag
*            介面標誌

public void pushFragments(Fragment fragment, boolean shouldAnimate,
boolean addToBackStack, String tag) {
FragmentManager manager = getSupportFragmentManager();// getFragmentManager();
FragmentTransaction ft = manager.beginTransaction();
if (shouldAnimate) {
// ft.setCustomAnimations(R.animator.fragment_slide_left_enter,
// R.animator.fragment_slide_left_exit,
// R.animator.fragment_slide_right_enter,
// R.animator.fragment_slide_right_exit);
}
ft.replace(R.id.sdk_main_content, fragment, tag);
// ft.attach(fragment);


if (addToBackStack) {
/*
* here you can create named backstack for realize another logic.
* ft.addToBackStack("name of your backstack");
*/
ft.addToBackStack(tag);
} else {
/*
* and remove named backstack:
