资源不是可绘制的 [英] Resource is not a Drawable

问题描述

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

This code causes force close exception on Emulator(API 18) and works in ASUS Nexus 7(API 21)

<View
    android:layout_width="400dp"
    android:layout_height="2dp"
    android:layout_marginTop="30dp"
    android:background="@color/light_gray" />

如果我将@color/light_gray替换为#EBEBEB，则在两种设备上均可正常运行.

If I am replacing @color/light_gray with #EBEBEB works perfectly on both device.

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}

所以我转向以下代码中的drawable

So I moved to drawable on following code,

<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" />

这引发了以下异常，

 Caused by: android.content.res.Resources$NotFoundException: File res/drawable-hdpi-v4/login_btn_selected.xml from drawable resource ID #0x7f020095

所以我试图将login_btn_selected.xml放在res/drawable-hdpi-v4/文件夹中，然后说在res/drawable-hdpi/和res/drawable-hdpi-v4/之间出现重复文件，所以我从res/drawable-hdpi/中删除了它，然后再次在相同的资源中找不到异常v4文件夹，

So I tried to place the login_btn_selected.xml in 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,

Caused by: android.content.res.Resources$NotFoundException: File res/drawable-hdpi-v4/login_btn_selected.xml from drawable resource ID #0x7f020095

所以最后我来到了 SO .

问题是

1. 我想知道是仅在模拟器中还是在真实设备中也存在此问题.

1. I want to know is this problem in emulator only or in real device too.

如果在真实设备中也意味着我该如何克服呢?

If in real device too means how can I overcome this?

我想使用@color/light_gray而不是硬编码，而且我想使用可绘制的选择器.

I want to use @color/light_gray instead of hard coding, Also I want to use drawable selectors.

注意::我已删除并重新创建了模拟器，没有用.同样，我也在API 19模拟器上进行了测试.

NOTE: I have deleted and recreated the Emulator, no use. I have tested on API 19 emulator also, same issue.

任何解决方案都是高度可取的.

Any solution will be highly appreciable.

推荐答案

这是因为我的色彩资源文件位于\res\values-21文件夹下，现在将其移至\res\values\文件夹下，现在应用程序运行正常.谢谢朋友.

It is because my color resource file is under \res\values-21 folder, Now moved it to \res\values\ folder, Now app works fine. thank you friends.
