POWrong when scroll listview with adapter
text
Body
copied!<p>(Sorry I'm not good at English) I haved created a custom BaseAdapter to show my data from sqlite to a ListView. Now I can see list but when i scroll listview quickly, rows are view oddly. I can't understand this. And one more strange point is that, if i have 5 data row, getView run 5 time but only first 4 row can be show. I use log and i see 5 time "return view;" clearly.</p> <p>Here are my adapter code:</p> <pre><code>public class LocalRankAdapter extends BaseAdapter { private static final String FIELD1 = "time"; private static final String FIELD2 = "name"; private static final String TABLE_NAME = "rank"; private static final String FIELD_ORDER = "time"; private DataBaseHelper dbHelper; private Cursor mCursor; private Context mContext; private int timeColIndex; private int nameColIndex; private int index; private int length; public static float recent_time=0; public static String recent_playerName=""; public LocalRankAdapter(Context context, DataBaseHelper mdbHelper) { mContext=context; dbHelper=mdbHelper; // get data from database mCursor = dbHelper.getData(TABLE_NAME, new String[] { FIELD1, FIELD2 }, FIELD1 + " !=0 ", FIELD_ORDER + " ASC"); mCursor.moveToFirst(); length=mCursor.getCount(); timeColIndex=mCursor.getColumnIndex(FIELD1); nameColIndex=mCursor.getColumnIndex(FIELD2); index=1; } public static void insertData(DataBaseHelper dbHelper, float currentTime, String name) { ContentValues cv=new ContentValues(); cv.put(FIELD1, currentTime); cv.put(FIELD2, name); dbHelper.insertData(TABLE_NAME, new String[] {FIELD1, FIELD2}, cv); } @Override public int getCount() { return length-1; } @Override public View getView(int id, View convertView, ViewGroup parent) { View v=convertView; if (convertView == null) { v=convertView; LayoutInflater inflater = (LayoutInflater) mContext .getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = inflater.inflate(R.layout.list_item, parent, false); TextView rankNumber=(TextView) v.findViewById(R.id.txtRank); TextView time=(TextView) v.findViewById(R.id.txtTime); TextView playerName=(TextView) v.findViewById(R.id.txtPlayerName); String timeStr=mCursor.getString(timeColIndex); String playerNameStr=mCursor.getString(nameColIndex); if(Float.parseFloat(timeStr)==(recent_time/1000f) && playerNameStr.equals(recent_playerName)) { v.setBackgroundColor(mContext.getResources().getColor(R.color.item_bg_recent)); rankNumber.setText(String.valueOf(index++)+" (Your)"); } else rankNumber.setText(String.valueOf(index++)); time.setText(timeStr); playerName.setText(playerNameStr); mCursor.moveToNext(); return v; } return v; } @Override public Object getItem(int id) { return id; } @Override public long getItemId(int arg0) { return 0; } public static void setModeView(int mtime, String mplayerName) { recent_time=mtime; recent_playerName=mplayerName; } </code></pre> <p>}</p>
