找不到可绘制的资源

Question

我试图为自定义实现选择器可绘制资源ArrayAdapter.我一直在得到一个android.content.res.Resources$NotFoundException: File res/drawable/list_selector.xml from drawable resource ID #0x7f020

有人可以提供建议吗？

我有两个xml文件:

RES /抽拉/ list_selector.xml

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

RES /布局/ list_item.xml

<?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="match_parent"
    android:orientation="horizontal" >

    <TextView 
        android:id="@+id/casualty_text_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/list_selector"/>

</LinearLayout>

最后,我的代码加载列表项,如下所示:

    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        TCCC cur_object = getItem(position);

        View cur_view = convertView;
        if(cur_view == null)
        {
            System.out.println("Inflating!");
            cur_view = View.inflate(getContext(), R.layout.list_item, null);
            String text_value = (cur_object.m_name.length() == 0) ? "New Casualty" : cur_object.m_name;

            TextView name_box = (TextView)cur_view.findViewById(R.id.casualty_text_view);
            if(name_box != null)
                name_box.setText(text_value);
        }

        return cur_view;
    }

看看@Nebraska建议的帮助.

否则,试试这个:

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