在导航抽屉内部管理片段中的线程(用于平滑动画)

Question

我想问一下你中的某人是否遇到与我相同的问题。

I/art: Do partial code cache collection, code=250KB, data=130KB
I/art: After code cache collection, code=248KB, data=129KB
I/art: Increasing code cache capacity to 1024KB
I/Choreographer: Skipped 143 frames!  The application may be doing too much work on its main thread.

我的Android应用程序的设计很简单，我在着陆页中有一个导航抽屉，然后我有在每个抽屉中有多个片段我仅在使用Navdrawer的着陆页上使用活动。

当我尝试添加一个公共存储库时，例如日历，在我的每个片段上回收视图时，我都会收到上面的错误。

我在线阅读了一些文章和示例，发现我应该使用 asynctask＆lt;> 或 runonuithread 并运行与 Operations 主线程/UI线程。事件尽管我尝试将这些线程应用于我的片段上的同样错误。

但是操作并不是很重，我只是加载了日历库并将它们实例化在我的片段内的increateview上...

我希望您可以给我一些建议或最佳实践来管理这种情况...我知道有人遇到了同样的问题。呵呵。预先感谢。

我尝试了此链接，但更可能是另一种情况

根据代码要求：

在onCreateview相同的结果上调用此内容：

setUpCalendarView(view); // First try without asynTask
// Second try with asynTask
//        UICalendarLibTask mCalendarTask = new UICalendarLibTask(view);
//        mCalendarTask.execute((Void) null);

这是我的XML布局：

android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="20sp"
android:background="@drawable/background">

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/frameLayoutCalendar">
    <com.marcohc.robotocalendar.RobotoCalendarView
        android:id="@+id/robotoCalendarPicker"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</FrameLayout>
<FrameLayout
    android:layout_width="match_parent"
    android:id="@+id/frameLayoutButton"
    android:layout_height="wrap_content">
    <Button
        android:text="TEST RANDOM"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/markDayButton" />
</FrameLayout>
<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:isScrollContainer="true"
    android:id="@+id/frameLayoutListOfServices">
    <android.support.v7.widget.RecyclerView
        android:id="@+id/calendar_service_job_list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:clipToPadding="false"
        android:paddingTop="60dp" />
</FrameLayout>

好吧，我没有看到线程中的任何错误，尤其是在填充卡片时，但是当我尝试同时渲染recyclerview和同一片段上的日历时，我会在上面的错误

上获得错误

注意：我正在使用GitHub的仓库进行日历视图robotocalendar github

我不明白解决方案背后的奥秘，但这解决了我的问题...

之前

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="20sp"
    android:background="@drawable/background">
<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/frameLayoutCalendar">
<com.marcohc.robotocalendar.RobotoCalendarView
    android:id="@+id/robotoCalendarPicker"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

之后（我刚刚删除了行android:background="@drawable/background"）

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="20sp">
<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
android:id="@+id/frameLayoutCalendar">
<com.marcohc.robotocalendar.RobotoCalendarView
    android:id="@+id/robotoCalendarPicker"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

有人会向我解释这种情况...我是否真的不需要为没有此脉络图错误的原因设置布局的背景，谢谢！

我希望有人也会有所帮助，
