創建ListView圖標和文本時動態數組而不是靜態Android

Question

我正在使用下面的代碼創建一個帶有文本和圖標的ListView，但問題出在哪裏，下面我希望數組是動態的而不是靜態的我的列表動態創建而不是統計。我的最終目標是從我的Db中檢索特定的字符串，然後在列表視圖中顯示它，每列中的每個字符串都將顯示在其中。 非常感謝您提前。

我的源代碼：

import java.util.ArrayList; 
    import android.app.Activity; 
    import android.app.ListActivity;

    import android.widget.ListView; 
    import android.widget.TextView; 
    import android.widget.Toast; 

    public class History extends ListActivity implements OnItemClickListener { 

String keyWord = ""; 
String histDesRes = ""; 
String history = ""; 
String rawImage; 
ArrayList<String> Ra = new ArrayList<String>(); 
SQLiteDatabase mydb; 
TextView selection; 
public String[] result={keyWord, "ipsum", "dolor",

     history = keyWord+" "+ histDesRes; 
     c.moveToNext();

    // close everything 
    c.close(); 
    mydb.close(); 
    setListAdapter(new IconicAdapter());

} 

public void onListItemClick(ListView parent, View v, int position, long id) {

     View row = inflater.inflate(R.layout.row, parent, false); 
     TextView label = (TextView) row.findViewById(R.id.label); 
     label.setText(result[position]); 

     ImageView icon = (ImageView) row.findViewById(R.id.icon); 


      icon.setImageResource(R.drawable.ok); 

     return (row); 
    } 
} 

@Override 
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { 
    // TODO Auto-generated method stub 

} 

    } 

    /** 
    * On Item click event for the list view

while (c.isAfterLast() == false) { 
     rawImage = c.getString(c.getColumnIndex("couponThumbnailResult")); 
     keyWord = c.getString(c.getColumnIndex("keyWordResult")); 
     histDesRes = c.getString(c.getColumnIndex("historyDescriptionResult")); 
     //Toast.makeText(getApplicationContext(), 
     //history, Toast.LENGTH_LONG).show(); 
     history = keyWord+" "+ histDesRes; 
     //Use an ArrayList to store your results from the DB 
     c.moveToNext(); 
    } 

String[] results = yourArrayList.toArray(); 

使用此數組中的適配器....
