ListActivity为StartActivity

Question

HY。

我的startactivity应该是ListActivity。

public class Main extends ListActivity

布局：

<?xml version="1.0" encoding="utf-8"?>
    <ListView android:id="@+id/listView1" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"></ListView>

每次我启动应用程序时都会崩溃。

请帮忙

Answer 1

如果是ListActivity，则必须按以下方式调用默认列表：

<ListView android:id="@android:id/list"

请参阅开发人员文档 http://developer.android.com/reference/android/app/ListActivity.html

Answer 2

使用此android:id="@android:id/listView1代替android:id="@+id/listView1

如果你的listactivity必须像这样声明id

Answer 3

at Your content must have a ListView whose id attribute is 'android.R.id.list'

如果要扩展ListActivity，则不应使用setContentView(R.layout.main)。

所以从代码中删除setContentView（R.layout.main）。
