Android - 膨胀 TextView 时出错

标签 android android-layout android-fragments

我知道在 stackoverflow 上有很多类似的问题。 但是这些都不能解决我的问题。

这与主题设置或未找到资源无关。 而且我没有在此布局中加载大图像(所有背景都来自可绘制的 xml)。 所有属性都有准确的值，包括 namespace 声明。 它只是随机抛出这个异常。 看起来像一个 android 错误。

它发生在 Nexus 5X、Nexus 6P、HTC_A9u、ASUS_Z012 等设备上。 我正在使用 API 25、支持库 25.0.1、构建工具 25.0.2。

在我改为使用 API 25 后，它开始报告此异常。

布局中有 20 个相似的节点 ScrollView . 还有一个 Fragment持有这种布局。 我用 fragment 事务初始化它，然后把它放在 DrawerLayout 中。 .

布局节点:

<ScrollView
    android:id="@+id/mainMenuScrollView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="10dp">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        ...

        <RelativeLayout
            android:id="@+id/aboutHolder"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dp"
            android:paddingTop="7dp"
            android:paddingBottom="7dp"
            android:paddingStart="10dp"
            android:paddingEnd="5dp"
            android:clickable="true"
            android:background="?theme.mainMenuItemBackground"
            android:layout_below="@+id/otherHolder">
            <TextView
                    android:id="@+id/aboutCapital"
                    android:layout_width="30dp"
                    android:layout_height="30dp"
                    android:layout_centerVertical="true"
                    android:background="@drawable/my_background"
                    android:gravity="center"
                    android:textSize="14sp"
                    android:textColor="?theme.titleColor"
                    android:text="A"/>
            <TextView
                    android:id="@+id/aboutName"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_centerVertical="true"
                    android:layout_marginStart="10dp"
                    android:layout_toEndOf="@+id/aboutCapital"
                    android:textStyle="bold"
                    android:textSize="@dimen/menu_item_title"
                    android:textColor="?theme.titleColor"
                    android:text="About"/>
        </RelativeLayout>

        ...

    </RelativeLayout>

</ScrollView>

它也发生在 ScrollView 上或类似 <unknown> 的东西.

最佳答案

我认为你的问题是:

android:textColor="?theme.titleColor"

您应该更改为@color/yourcolor 或十六进制颜色
