刚才又查看了下issue,新版本的fragment中这个方法可以用来实现:extraTransaction().startDontHideSelf(fragment)
from fragmentation.
@duchengzhen 你的Fragment复写下int getWindowBackground()
方法,这个方法是取windowBackground背景的,你复写直接返回你的背景资源即可(注:int是资源id,不是color)
from fragmentation.
@duchengzhen 我在检查代码的时候发现,其实你只要给Fragment的根布局设置 background,Fragmentation就不会把背景设为windowBackground的了:
if (view != null && view.getBackground() == null) { int background = getWindowBackground(); view.setBackgroundResource(background); }
但是你想通过设置背景色是透明,并通过该Fragment看到下面的Fragment视图,直接设置透明背景并不会直接起作用,因为透过该Fragment看到的是Activity的背景色或者是windowBackground;
原因在于你start了Fragment后,上一个Fragment的视图就是GONE的了;
你可以通过以下代码让上一个Fragment的视图暂时变为看见,这样就可以达到通过当前透明Fragment可以看到前一个Fragment的视图了:
getPreFragment().getView().setVisibility(View.VISIBLE);

非常感谢,还是源码和fragment理解不透彻的原因
