这里是布局xml代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="com.homers.health_coach.MainActivity"
    tools:showIn="@layout/app_bar_main">
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <fragment
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            class="com.homers.health_coach.fragment_community"
            android:id="@+id/fragment_community" />

        <fragment
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            class="com.homers.health_coach.fragment_workout_list"
            android:id="@+id/fragment_workout_list" />
    </FrameLayout>
</LinearLayout>

58line是

setContentView(R.layout.activity_main);

请告诉我为什么会发生以及如何解决它.. 请帮帮我。 感谢：）

3 个答案:

答案 0 :(得分：0)

<{1}} onCreateView()因某种原因返回fragment_workout_list。

答案 1 :(得分：0)

错误非常明显，您可能未在onCreateView的{​​{1}}方法中返回视图：

  

由java.lang.IllegalStateException引起：片段com.homers.health_coach.fragment_workout_list没有创建视图。

确保在fragment_workout_list：

中有类似的内容 
fragment_workout_list

答案 2 :(得分：0)

您尚未在线性布局中指定方向，我认为在您的情况下应该是垂直的。据我所见，错误清楚地表明xml文件有问题，因此无法充气
