我试图为自定义ArrayAdapter实现选择器可绘制资源.我一直得到一个
android.content.res.Resources $NotFoundException：来自可绘制资源ID的文件res / drawable / list_selector.xml#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;
}
解决方法
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>
