單個活動有3個碎片崩潰

[英]Single Activity With 3 Fragments Crashing

 原文  2017-12-31 22:52:48  5   1    java/ android/ android-fragments

問題描述

我創建了一個身份驗證活動，該活動具有一個FrameLayout作為容器，在其中替換用戶想要使用的相應片段。

容器中的第一個片段是WelcomeFragment ，它只是一個ConstraintLayout ，具有背景，用於徽標的ImageView和兩個按鈕以移至LoginFragment或SignUpFragment 。

問題是，當我從WelcomeFragment到LoginFragment去，回來的WelcomeFragment，轉到SignUpFragment，並再次嘗試翻盤的WelcomeFragment，應用程序崩潰，並且給了我以下錯誤：

/**
 * Replace an existing fragment that was added to a container.  This is
 * essentially the same as calling {@link #remove(Fragment)} for all
 * currently added fragments that were added with the same containerViewId
 * and then {@link #add(int, Fragment, String)} with the same arguments
 * given here.
**/
public abstract FragmentTransaction replace(@IdRes int containerViewId, Fragment fragment,
        String tag)

如您所見，replace（）方法刪除了所有先前的片段，因此不必在函數replaceFragmentInActivity()使用popBackStackImmediate方法。

我建議使用findFragmentByTag(String tag)查找給定的片段是否存在，並跳過事務。
