android - 您必须在某些设备中提供 layout_width 属性

Question

我在我的应用程序中遇到了这个问题，我似乎无法理解它是如何发生的。它只发生在 Samsung Galaxy Y 手机上，我在其他设备上试过这段代码，没问题。

java.lang.RuntimeException: Unable to start activity ComponentInfo{jpac.remaster.gtc/jpac.remaster.gtc.GTCSplash}: java.lang.RuntimeException: Binary XML file line #7: You must supply a layout_width attribute.

谁能帮我解决这个问题？顺便说一句，这是有问题的 xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/tuna" >

    <ImageView
        android:id="@+id/dev_logo"
        android:layout_width="@dimen/speech_height"
        android:layout_height="@dimen/badge_height"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:contentDescription="@string/empty"
        android:scaleType="centerInside"
        android:src="@drawable/logo_dark" />

</RelativeLayout>

此 xml 文件的 Activity 也是应用程序的主要入口点。

提前致谢。

如果您为特定密度或屏幕尺寸指定了尺寸(或任何其他值或资源)，请确保您也在通用目录中定义了它们(即“值”、“可绘制”)
