在调用了大约 30 次 fragmentTransaction.replace() 后，FragmentActivity 意外关闭答案

【问题描述】：

我有一个测试应用程序，它的问题存储在数据库中。我的 FragmentActivity 包含一个片段，当从 AppBar 中选择新问题时，该片段将被替换。当我选择一个新问题大约 30 次时，FragmentActivity 意外关闭并将我带到我之前返回堆栈中的 Activity。

在 Verbose 级别的 Logcat 上，我没有看到任何与我的应用程序相关的内容。

我的xml代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<RelativeLayout
    android:id="@+id/fragment_container"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" />

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:background="@drawable/buttonshape"
    android:orientation="horizontal">

    <HorizontalScrollView
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1">

        <LinearLayout
            android:id="@+id/linearLayoutAppbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="horizontal">

        </LinearLayout>
    </HorizontalScrollView>

    <ImageView
        android:layout_width="50dp"
        android:layout_height="match_parent"
        android:src="@drawable/s202_background" />
</LinearLayout>

RelativeLayout 在调用 fragmentTransaction.replace() 时总是被片段替换；在下面的 LinearLayout 中是我的 AppBar，它以编程方式创建了代表数据库中每个问题的按钮。

当一个按钮被点击时 OnClickListener 被调用并识别哪个按钮被点击然后在一个新的方法中调用 fragmentTransaction.replace(); 这是该方法的代码：

    private void question1() {
    testPrasanjaCursor = BazaNaPrasanja.testDatabase.query(VozackaDbContract.TABLE_NAME_TABELA_TEST, null, null, null, null, null, null);
    fragmentTransaction = fragmentManager.beginTransaction();
    testPrasanjaCursor.moveToPosition(0);

    fragmentTransaction.replace(R.id.fragment_container, fragmentZnaci4);
    fragmentTransaction.commit();
    testPrasanjaCursor.close();
}

我不知道是 Sqlite 数据库导致它还是 FragmentManager 导致我在 Verbose 中没有与我的 Appliaction 相关的任何信息。

编辑：添加了 Logcat，这里是所有 logcat，因为我在 Emulator 上单击运行直到它关闭 FragmentActivity：

【解决方案1】：

我不确定我的回答是否对你有帮助，但你可以试试，告诉我在性能方面是否相同或不同

yourContentView= (LinearLayout) findViewById(R.id.content_main1);
yourContentView.removeAllViews();

【讨论】：

你的意思是我的主要 LinearLayout 的 id 为 "layoutMain" 对吗？
是的，您想用另一个问题更改其内容的布局
好吧，在选择问题时更改其内容的布局是 ID 为“fragment_container”的 RelativeLayot，当我单击按钮时，我将其布局替换为另一个片段。我会尝试你的答案并告诉你它是否有效。
我试过了，打开30个左右的问题后它仍然关闭。不幸的是，这不起作用
很抱歉，那么您将发布 Logcat

【解决方案2】：

我找到了一个简单的解决方案。在打开 25 个问题时，我重新创建了相同的活动。貌似这个bug和Activity有关，可能每个Activity最多可以替换30个Fragment。
