Resource is not a Drawable
提问by Gunaseelan
This code causes force close exception on Emulator(API 18) and works in ASUS Nexus 7(API 21)
此代码在 Emulator(API 18) 上导致强制关闭异常并在 ASUS Nexus 7(API 21) 中工作
<View
android:layout_width="400dp"
android:layout_height="2dp"
android:layout_marginTop="30dp"
android:background="@color/light_gray" />
If I am replacing @color/light_graywith #EBEBEBworks perfectly on both device.
如果我更换@color/light_gray与#EBEBEB作品都完美的设备上。
Exception is
例外是
Caused by: android.content.res.Resources$NotFoundException: Resource is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f080060 a=-1 r=0x7f080060}
So I moved to drawable on following code,
所以我在下面的代码中转向了 drawable，
<Button
android:layout_width="wrap_content"
android:layout_marginTop="30dp"
android:layout_height="wrap_content"
android:ems="10"
android:background="@drawable/login_btn_selector"
android:text="Login"
android:id="@+id/btnLogin" />
This one throws following exception,
这个抛出以下异常，
Caused by: android.content.res.Resources$NotFoundException: File res/drawable-hdpi-v4/login_btn_selected.xml from drawable resource ID #0x7f020095
So I tried to place the login_btn_selected.xmlin res/drawable-hdpi-v4/folder, Then it says duplicate file occur between res/drawable-hdpi/and res/drawable-hdpi-v4/, So I removed it from res/drawable-hdpi/, Then again same resource not found exception in v4 folder,
因此，我尝试将login_btn_selected.xmlin res/drawable-hdpi-v4/文件夹放入，然后它说在res/drawable-hdpi/和之间出现重复文件res/drawable-hdpi-v4/，所以我将其从 中删除res/drawable-hdpi/，然后在 v4 文件夹中再次未找到相同的资源异常，
Caused by: android.content.res.Resources$NotFoundException: File res/drawable-hdpi-v4/login_btn_selected.xml from drawable resource ID #0x7f020095
So finally I came to SO.
所以最后我来到了SO。
The problem is,
问题是，
- I want to know is this problem in emulator only or in real device too.
If in real device too means how can I overcome this?
I want to use
@color/light_grayinstead of hard coding, Also I want to use drawable selectors.
- 我想知道这个问题是仅在模拟器中还是在真实设备中。
如果在真实设备中也意味着我该如何克服这个问题？
我想使用
@color/light_gray而不是硬编码，我也想使用可绘制的选择器。
NOTE:I have deleted and recreated the Emulator, no use. I have tested on API 19 emulator also, same issue.
注意：我已经删除并重新创建了模拟器，没有用。我也在 API 19 模拟器上测试过，同样的问题。
Any solution will be highly appreciable.
任何解决方案都将是非常可观的。

It is because my color resource file is under \res\values-21folder, Now moved it to \res\values\folder, Now app works fine. thank you friends.
这是因为我的颜色资源文件在\res\values-21文件夹下，现在将它移到\res\values\文件夹中，现在应用程序工作正常。谢谢朋友。

Also make sure you don't have the background of an imageView set to selectableItemBackgroundBorderless, otherwise older devices will have this error:
还要确保您没有将 imageView 的背景设置为selectableItemBackgroundBorderless，否则旧设备将出现此错误：
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="?android:selectableItemBackgroundBorderless" />

I was struck with the same problem in the recent app I made. In my case, the problem was I put an image in the folder called drawable-v21, which is not available in older android API.
在我最近制作的应用程序中，我遇到了同样的问题。就我而言，问题是我在名为 drawable-v21 的文件夹中放置了一个图像，该图像在较旧的 android API 中不可用。
The solution is to put your drawable in drawable-...dpi folders too.
解决方案是将您的 drawable 也放在 drawable-...dpi 文件夹中。

Your color resource must reside in an Android resource file (i.e.: in the colors.xmlfile).
Android would not complain whereyou set it, but it mustbe defined as a color resource.
您的颜色资源必须驻留在 Android 资源文件中（即：在colors.xml文件中）。
Android 不会抱怨你在哪里设置它，但它必须被定义为颜色资源。
I.e.:
IE：
<color name="light_gray">#ebebeb</color>

The names appear not to match...
See this line:

请参阅此行：

Then you say: So I tried to place the login_btn_selected.xml.

I think the best way of doing this is, first create a xml file inside the "drawable" folder and do something like below.
我认为最好的方法是，首先在“drawable”文件夹中创建一个 xml 文件，然后执行如下操作。
e.g. light_gray.xml then do something like below.
例如，light_gray.xml 然后执行如下操作。
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="@color/light_gray" />
</shape>
once you have saved it.
一旦你保存了它。
change you code like below.
像下面这样改变你的代码。
<View
android:layout_width="400dp"
android:layout_height="2dp"
android:layout_marginTop="30dp"
android:background="@ drawable/light_gray" />
But make sure to put the file light_gray.xml only to "drawable" folder. Do not put the same file to "drawable-hdpi or drawable-hdpi-v4 and so on"
但请确保将文件 light_gray.xml 仅放在“drawable”文件夹中。不要把同一个文件放到“drawable-hdpi 或 drawable-hdpi-v4 等等”
