从列表视图传递到新活动的错误

我有一个列表视图，当我点击一个项目时，它显示一条消息，然后当我点击“确定”时，我想传递给另一个活动，这是我的代码：从列表视图传递到新活动的错误

public void onItemClick(AdapterView<?> parent, View view, int position, 
       long id) { 
// TODO Auto-generated method stub 
ServerContent item = listAdapter.getItem(position); 
Log.e("onitemclick","listadapter"); 
item.select(); 

newactivity n = new newactivity(); 
    Intent newActivity = new Intent();  
startActivity(newActivity); 
      }

，我在manifest.xml

<activity android:label="@string/app_name" android:name="newactivity"/>

添加此此newactivity：

public class newactivity { 
    Intent intent; 
    protected void onCreate(Bundle savedInstanceState) { 

     intent = getIntent(); 
     intent.addCategory("category"); 
     //String value = intent.getStringExtra("key"); //if it's a string you stored. 
} 

    private Intent getIntent() { 
     // TODO Auto-generated method stub 
     Intent n = new Intent(); 
     n.addCategory(" "); 
     return n; 
    }

我得到了这些错误

我希望它不是一个错字：

<activity android:label="@string/app_name" android:name="newactivity"/>

没有 “”这里是活动的名称。它应该是这样的：

<activity android:label="@string/app_name" android:name=".newactivity"/>

或者你甚至可以指定活动如完全合格的名称。

<activity android:label="@string/app_name" android:name="com.yourproject.activity.newactivity"/>
