如何獲得在android中使用hashmap的整體價值？

Question

嗨我noob到android，我嘗試使用rgb顏色代碼顯示數據庫中的顏色，我使用hashmap來映射數據和字段的數據會來，但我有分貝的rgb顏色代碼它會來正確我的問題是，它只會從數據庫顯示最後的顏色值..如何讓所有的價值和色彩修正到文本字段..

public class AndroidJSONParsingActivity extends Activity { 
static String items; 
static String items1; 
static String dates; 
static String finalDate; 
int a,r,g,b; 
ListView lv2; 
TextView text1; 
String COLOR; 
private static final String TAG_JSONDataResult = "JSONDataResult"; 
private static final String TAG_GRPNAME = "GRPNAME"; 
private static final String TAG_QNT = "QTY"; 
private static final String TAG_BUDGET = "BUDGET"; 
private static final String TAG_STOCK = "STOCK"; 
private static final String TAG_DIFF = "DIFF"; 
private static final String TAG_DIFF_P = "DIFF_P"; 

private static final String TAG_COLOR = "COLOR"; 


@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    lv2=(ListView)findViewById(R.id.list); 
    Bundle b=this.getIntent().getExtras(); 
    items=b.getString("item"); 
    items1=b.getString("item1"); 
    dates=b.getString("date"); 

    SimpleDateFormat dateFormat = new SimpleDateFormat(
      "yyyy-MM-dd"); 
    Date myDate = null; 
    try { 
     myDate = dateFormat.parse(dates); 

    } catch (ParseException e) { 
     e.printStackTrace(); 
    } 

    SimpleDateFormat timeFormat = new SimpleDateFormat("yyyy-MM-dd"); 
    finalDate = timeFormat.format(myDate); 

    torun(); 

} 

public void torun() { 
    String myUrl; 
    myUrl = String.format("http://10.0.2.2:51382/RestServiceImpl.svc/jsons/?Location=%s&GROUP=%s&asondate=%s",items.replaceAll(" ","%20"),items1.replaceAll(" ","%20"),finalDate); 

    final ArrayList<HashMap<String, String>> contactList = new ArrayList<HashMap<String, String>>(); 

    // Creating JSON Parser instance 
    JSONParser jParser = new JSONParser(); 
    // getting JSON string from URL 

    try { 

     JSONObject json1 = jParser.getJSONFromUrl(myUrl); 
     // Getting Array of Contacts 
     JSONArray list = json1.getJSONArray(TAG_JSONDataResult); 


     // looping through All Contacts 
     for(int i = 0; i < list.length(); i++){ 
      JSONObject c = list.getJSONObject(i); 

      String GRPNAME = c.getString(TAG_GRPNAME); 
      String QTY = c.getString(TAG_QNT); 
      String BUDGET = c.getString(TAG_BUDGET); 
      String STOCK = c.getString(TAG_STOCK); 
      String DIFF = c.getString(TAG_DIFF); 
      String DIFF_P = c.getString(TAG_DIFF_P); 

      COLOR = c.getString(TAG_COLOR); 

      // creating new HashMap 
      HashMap<String, String> map = new HashMap<String, String>(); 

      map.put(TAG_GRPNAME, GRPNAME);

      lv2.setAdapter(adapter);

Answer 1

你可以在contactList中添加hashmaps，同時使用datatList設置適配器？

Answer 2

試圖聲明地圖外的for循環並初始化它的每一個時間。這就是爲什麼你持續獲得同樣的價值。

 HashMap<String, String> map = new HashMap<String, String>(); 
     for(int i = 0; i < list.length(); i++){ 
     // 
     // 
     ... 
     // 

     map = new HashMap<String, String>(); 

     map.put(TAG_GRPNAME, GRPNAME); 

     map.put(TAG_QNT, QTY); 
     map.put(TAG_BUDGET, BUDGET); 
     map.put(TAG_STOCK, STOCK); 
     map.put(TAG_DIFF, DIFF); 
     map.put(TAG_DIFF_P, DIFF_P); 

     map.put(TAG_COLOR,COLOR); 
     //map.put(TAG_PHONE_MOBILE, mobile); 

     // adding HashList to ArrayList 
     dataList.add(map);
