寻找可绘制资源时NotFoundException [英] NotFoundException when looking for Drawable resource

问题描述

我开始与Android，我想描述的在这个答案。所以，我创建了cell_background.xml文件，Eclipse在水库创建\\绘制并包含

I am starting with android and I want to add a border to cells as described in this answer. So I created my cell_background.xml file, which Eclipse created in res\drawable and that contains

<?xml version="1.0" encoding="utf-8"?>
<shape
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:shape= "rectangle"  >
    <solid android:color="#000"/>
    <stroke android:width="1dp"  android:color="#ff9"/>
</shape>

看了，有与绘制文件夹中的几个问题，我复制它逐字到水库\\ drawable- * DPI 目录

现在，下面这行我的应用程序崩溃

Now, my app crashes in the following line

Drawable drawable = Resources.getSystem().getDrawable(R.drawable.cell_background);

与此异常

12-16 14:26:28.624: E/AndroidRuntime(533): Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x7f020000

这两个项目和仿真器设置为3.0

Both the project and the emulator are set to v3.0

任何想法？我已经清理和重建项目，但它仍然崩溃。

Any ideas? I have already cleaned and rebuilt the project but it still crashes.

推荐答案

的问题是，你使用Resources.getSystem（），它会给你的系统资源的引用。您应该使用context.getResources（）代替。

The problem is that you use Resources.getSystem(), which will give you a reference to the system resources. You should use context.getResources() instead.
