ListView，防止添加新項目

Question

我有我的listview活動工作得很好，但我有一個惱人的問題。 無論何時恢復，它都會在列表中添加相同的項目，並且這個項目會變得更大。我只是想讓它保持我首先想到的價值。 我該怎麼做？ 這裏是我的活動

public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     setContentView(R.layout.custom_list_view); 

     adapter = new SimpleAdapter(
       this, 
       list, 
       R.layout.custom_row_view, 
       new String[] {"pen","price","color"}, 
       new int[] {R.id.text1,R.id.text2, R.id.text3} 
       ); 


     populateList(); 
     setListAdapter(adapter); 
    } 

這裏是我的ArrayList：

static final ArrayList<LinkedHashMap<String,String>> list = 
     new ArrayList<LinkedHashMap<String,String>>(); 

    private void populateList() { 
     LinkedHashMap<String,String> temp = new LinkedHashMap<String,String>(); 
     temp.put("pen","        Mission name");  
     list.add(temp); 
     LinkedHashMap<String,String> temp1 = new LinkedHashMap<String,String>(); 
     temp1.put("pen","       Map activity");   

     list.add(temp1); 
     LinkedHashMap<String,String> temp2 = new LinkedHashMap<String,String>(); 
     temp2.put("pen","       Check sensors");  
     list.add(temp2); 

     LinkedHashMap<String,String> temp3 = new LinkedHashMap<String,String>(); 
     temp3.put("pen","       Infrared Image"); 
     list.add(temp3); 

     LinkedHashMap<String,String> temp4 = new LinkedHashMap<String,String>(); 
     temp4.put("pen","       Radar Image"); 
     list.add(temp4); 

     LinkedHashMap<String,String> temp5 = new LinkedHashMap<String,String>(); 
     temp5.put("pen","       Visual image"); 
     list.add(temp5); 

     LinkedHashMap<String,String> temp6 = new LinkedHashMap<String,String>(); 
     temp6.put("pen","       suscribe to Viewer"); 
     list.add(temp6); 
    }

不要聲明列表中爲靜態。 即：

final ArrayList<LinkedHashMap<String,String>> list = new ArrayList<LinkedHashMap<String,String>>();
