Android的没有的ListView适配器RESOURCEID [英] Android there is no ListView adapter resourceId
问题描述
基于Android中的Hello-的ListView turorial,的http://开发商.android.com /资源/教程/视图/ HELLO-listview.html
based on Hello-ListView turorial in Android, http://developer.android.com/resources/tutorials/views/hello-listview.html
在
setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, COUNTRIES));
有一个错误,因为没有R.layout.list_item
had an error because there is no R.layout.list_item
previously我曾跟随本教程中,创建于RES /布局文件夹中的文件list_item.xml
previously i had followed the tutorial, created the file list_item.xml on the res/layout folder
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:textSize="16sp">
</TextView>
它不具有不同的名称既不工作(main_list_view.xml)
it doesnt work with different name neither (main_list_view.xml)
这是完整的源
String[] appList;
ListView mainLv;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
appList = this.getResources().getStringArray(R.array.for_main_layout);
mainLv = (ListView)findViewById(R.id.ListView01);
mainLv.setAdapter(new ArrayAdapter<String>(this, R.layout.list_item, appList)); //<<
}
更新!
阿其作品现在创建新项目的时候!当我在第一个项目中使用文件>新建> Android的XML文件,它不工作,但现在在不同的项目中,我使用文件>新建>文件,也许这是一个可能的错误?
Updated! Ah its works now when creating new project! When i use File>new>Android XML File in the first project, it doesnt work, but now in different project, i use file>new>File, maybe is this a possible bug?
推荐答案
您可能已经使用了Android提供的布局:
You could have used the android supplied layout:
android.R.layout.simple_list_item_1
试试那个。
