android.content.res.Resources $ NotFoundException异常：来自drawable资源ID的文件res / drawable / my.xml

时间：2013-07-17 13:33:20

标签： android android-layout

这个xml有什么问题，我试图按下按钮的感觉。我得到一个例外，我无法理解。 ResourceNotFound

在我的layout.xml

中 
<Button
    android:id="@+id/submit"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/submitbuttonpress"
    android:text="Submit"
    android:textColor="#eeeee4"
    android:typeface="monospace" />

我在drawable文件夹中的submitbuttonpress.xml 

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="false" android:background="#AAAAAA" />
    <item android:state_pressed="true" android:background="#777777" />
</selector>

异常（logcat）

答案 0 :(得分：26)

一旦尝试这个

在选择器状态下，需要添加drawable，在您的情况下，您希望在选择器状态中添加颜色。因此可以使用资源中的颜色创建drawable。它将作为ColorDrawable

工作

请检查以下代码

<selector xmlns:android="http://schemas.android.com/apk/res/android">

        <item android:drawable="@drawable/clr_normal" android:state_pressed="false"/>
        <item android:drawable="@drawable/clr_pressed" android:state_pressed="true"/>

    </selector>

values / string.xml for color 

 <drawable name="clr_normal">#AAAAAA</drawable>
<drawable name="clr_pressed">#777777</drawable>

答案 1 :(得分：0)

属性android:background不存在。执行此操作的正确方法是首先使用以下内容创建新资源文件res/colors.xml：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="lt_gray">#AAAAAA</color>
    <color name="dk_gray">#777777</color>
</resources>

然后只需将selector更改为以下内容：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="false" android:drawable="@color/lt_gray" />
    <item android:state_pressed="true" android:drawable="@color/dk_gray" />
</selector>

这会自动创建一个ColorDrawable并将其指定为该状态的drawable。
