錯誤編譯Java代碼

Question

我找不到如何刪除這些錯誤在下面的代碼

package com.example.hellocodelearn; 
import java.util.ArrayList; 
import java.util.List; 

import android.app.ListActivity; 
import android.support.v7.app.ActionBarActivity; 
import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 
import android.widget.TextView; 

import com.example.hellocodelearn.models.Notes; 


public class NotesListActivity extends ListActivity 

{ 

    private ArrayAdapter NotesItemArrayAdapter ; 
    private List<Notes> notes = new ArrayList<Notes>() ; 

    for (int i = 0; i < 20; i++) 
    { 
     Notes tweet = new Notes(); 
     tweet.setTitle("A nice header for Tweet # " +i); 
     tweet.setBody("Some random body text for the tweet # " +i); 
     notes.add(tweet); 
    } 

@Override 
protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_notes_list); 

     NotesItemArrayAdapter = new NotesAdapter(this, new String[10]); 
     setListAdapter(NotesItemArrayAdapter); 
} 

@Override 
protected void onListItemClick(ListView l, View v, int position, long id) 
{ 
    Intent intent = new Intent(this, NotesDetailActivity.class); 
    startActivity(intent); 
} 


} 

我得到的錯誤：

Description Resource Path Location Type 
Syntax error on token ",", ; expected NotesListActivity.java /HelloCodeLearn/src/com/example/hellocodelearn line 47 Java Problem 

普萊斯help.Thanks。

Answer 1

你不能在你的類的主體中有一個for循環，它必須進入一個方法。

Answer 2

的for循環應該是一種方法，而不是類塊

protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_notes_list); 
    for (int i = 0; i < 20; i++) { 
     .... 
    } 
}
