Android:如何追踪 InflateException 的来源？

Question

在启动我的应用程序时，我在 Logcat 中收到以下警告:

04-09 10:28:17.830: WARN/WindowManager(52): Exception when adding starting window

我的应用程序以以下启动画面开始:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:windowBackground="@color/white" android:background="@color/white"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:foregroundGravity="center">

    <ImageView android:id="@+id/ImageView01"
        android:layout_width="fill_parent" android:layout_height="fill_parent"
        android:adjustViewBounds="true" android:scaleType="centerInside"
        android:src="@drawable/splash" android:layout_gravity="center" />


</ScrollView>

Splash 是在启动画面中显示的图像。我有这四个文件夹用于在我的应用程序中存储可绘制对象:

/res/drawable-hdpi
/res/drawable-ldpi
/res/drawable-mdpi
/res/drawable-nodpi

初始图像在前三个中都有自己的版本，并且可以正确显示。从 ImageView 中删除 src 属性会删除图像，但不会删除异常。

我有点迷失在哪里寻找异常的原因。我什至不知道这是否真的是这个布局文件等中的一个问题。

您将如何查找此警告的原因？

我有同样的错误。唯一有意义的 xml 第 24 行是我的应用程序 list ，它恰好是应用程序的结束标记。我将其追溯到我为应用程序添加的自定义主题——我没有定义样式的父级。我需要做的就是将 parent="android:Theme"添加到我的样式中，然后我的错误就消失了。

<style name="MyTheme" parent="android:Theme">
...
</style>
