活动中的错误来自：

setContentView(R.layout.summarycost_layout);

xml文件summarycost_layout是：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="fill_parent"
    android:background="@android:color/white"
    android:orientation="vertical" >

    <include
    android:id="@+id/includeTitle"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    layout="@layout/titlebar_layout" />

    <LinearLayout
    android:id="@+id/layout"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:orientation="horizontal" >

    <ListView
        android:id="@+id/summaryCostListview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/white" >
    </ListView>
    </LinearLayout>

    <LinearLayout
    android:id="@+id/layoutTotal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@android:color/white"
    android:gravity="center"
    android:orientation="horizontal"
    android:paddingLeft="10dp" >

    <TextView
        android:id="@+id/txtTotal"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:gravity="center_vertical"
        android:text="Total Cost(0/0)"
        android:textColor="@color/blue"
        android:textSize="18sp" />

    <TextView
        android:id="@+id/totalValue"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="$0"
        android:textColor="@color/blue" />

    <CheckBox
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:visibility="invisible" />
    </LinearLayout>

    <LinearLayout
    android:id="@+id/layout"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >

    <Button
        android:id="@+id/buttonCancel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@drawable/button_bg"
        android:text="@string/cancel"
        android:textColor="@android:color/white" />

    <Button
        android:id="@+id/buttonAll"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@drawable/button_bg"
        android:text="@string/select_all"
        android:textColor="@android:color/white" />

    <Button
        android:id="@+id/buttonAccept"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@drawable/button_bg"
        android:text="@string/accept"
        android:textColor="@android:color/white" />
    </LinearLayout>

</LinearLayout>

并且上面的xml文件中引用的titlebar_layout是：

<?xml version="1.0" encoding="utf-8"?>


<ImageView
    android:id="@+id/imgBack"
    android:layout_width="32dp"
    android:layout_height="32dp"
    android:onClick="onBackClick"
    android:src="@drawable/arrow_back" />

<TextView
    android:id="@+id/txtTitle"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:gravity="center_horizontal"
    android:textColor="@android:color/white" />

<ImageView
    android:id="@+id/imgForward"
    android:layout_width="32dp"
    android:layout_height="32dp"
    android:onClick="onForwardClick"
    android:src="@drawable/arrow_for" />

看来，问题来自于titlebar_layout的<ImageView。

我有点迷失在哪里寻找异常的原因。我甚至不知道这个布局文件中是否真的存在这个问题。

你会如何找到这个问题的原因？

感谢任何帮助。

答案 0 :(得分：1)

我已经经历了过去OP所建议的确切问题，而@shoe rat在他的评论中提到了正确的答案。

我猜你的PNG drawables不在基本'drawable'文件夹中，Android可以在你正在测试的设备或模拟器上找到匹配项。你可能无意中将你的arrow_back和button_bg drawables复制到例如drawable-large和drawable-xlarge中，但是在设备或模拟器上进行测试，比如说小（320x280）。在我的示例中，匹配规则找不到小屏幕大小的匹配因此android.content.res.Resources $ NotFoundException：资源不是Drawable（颜色或路径）错误结果。

因此，对于快速测试，将您的arrow_back和button_bg drawables（以及您拥有的任何其他内容）复制到drawable文件夹，它应该编译并运行而不会出现错误，因为drawable文件夹中的drawables将始终被找到并用作后备。然后，当然要确保为每个屏幕尺寸创建适当大小的drawable以适应所有屏幕变化，并阅读“How Android Finds the Best-matching Resource”以更好地理解Android中的可绘制匹配过程。
