清除无循环的backstack

String name = getSupportFragmentManager().getBackStackEntryAt(0).getName();
getSupportFragmentManager().popBackStack(name, FragmentManager.POP_BACK_STACK_INCLUSIVE);

addToBackStack()参数的名称在哪里

getSupportFragmentManager().beginTransaction().
                .replace(R.id.container, fragments.get(titleCode))
                .addToBackStack(name)

嗨~我找到了一个更好的解决方案，来自:https://gist.github.com/ikew0ng/8297033

    /**
 * Remove all entries from the backStack of this fragmentManager.
 *
 * @param fragmentManager the fragmentManager to clear.
 */
private void clearBackStack(FragmentManager fragmentManager) {
    if (fragmentManager.getBackStackEntryCount() > 0) {
        FragmentManager.BackStackEntry entry = fragmentManager.getBackStackEntryAt(0);
        fragmentManager.popBackStack(entry.getId(), FragmentManager.POP_BACK_STACK_INCLUSIVE);
    }
}

我在这里发布了类似的内容

来自约阿希姆的回答，来自Dianne Hackborn:

最后我只用了:

FragmentManager fm = getActivity().getSupportFragmentManager();
for(int i = 0; i < fm.getBackStackEntryCount(); ++i) {    
    fm.popBackStack();
}

但同样可以使用类似的东西:

((AppCompatActivity)getContext()).getSupportFragmentManager().popBackStack(String name, FragmentManager.POP_BACK_STACK_INCLUSIVE)

这将弹出所有的状态到指定的一个。然后你可以用你想要的东西替换这个片段

接受的答案对我来说是不够的。我不得不使用:

FragmentManager fm = getSupportFragmentManager();
int count = fm.getBackStackEntryCount();
for(int i = 0; i < count; ++i) {
    fm.popBackStackImmediate();
}

private boolean removeFragFromBackStack() {
    try {
        FragmentManager manager = getSupportFragmentManager();
        List<Fragment> fragsList = manager.getFragments();
        if (fragsList.size() == 0) {
            return true;
        }
        manager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
        return true;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return false;
}

工作为我和简单的方法不使用循环:

 FragmentManager fragmentManager = getSupportFragmentManager();
 //this will clear the back stack and displays no animation on the screen
 fragmentManager.popBackStackImmediate(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
