在Android中搜索自定義列表視圖？

我有一個自定義列表視圖與搜索功能，同時搜索它顯示所有列表目前在不同的ID？我缺少的東西。任何人都可以找到解決方案，感謝提前。在Android中搜索自定義列表視圖？

1.searchfunction類

sqlCon = new SQLiteConnectornew(this); 
    sqlCon.open(); 

     Cursor cursor = SQLiteConnectornew.fetchAllvalues1(); 
     //cursor.close(); 
    String[] from = new String[] { Contactsnew.TITLE}; 
    int[] to = new int[] { R.id.title }; 
    custAdapter = new CustomContactsAdapternew(this, 
      R.layout.activity_contactlist, null, from, to); 
    setListAdapter(custAdapter); 
    search = (EditText) findViewById(R.id.alertsearch); 
    search.addTextChangedListener(new TextWatcher() { 

     @Override 
     public void afterTextChanged(Editable s) { 
      // TODO Auto-generated method stub 
     } 

     @Override 
     public void beforeTextChanged(CharSequence s, int start, int count, 
       int after) { 
      // TODO Auto-generated method stub 

     } 

     @Override 
     public void onTextChanged(CharSequence s, int start, int before, 
       int count) { 
      // TODO Auto-generated method stub 
      custAdapter.getFilter().filter(s.toString()); 
     } 

    }); 
    custAdapter.setFilterQueryProvider(new FilterQueryProvider() { 
     public Cursor runQuery(CharSequence constraint) { 
      return SQLiteConnectornew.fetchCountriesByName1(constraint.toString()); 
     } 
    }); 
    listView.setAdapter(custAdapter); 
    listView.setTextFilterEnabled(true);

2.db類

public SQLiteConnectornew(Context context) { 
    sqlHp = new SQLiteHelpernew(context, Contactsnew.DB_NAME, null, 1); 
} 

public void insertContact(String title, String category, int _id1) { 
    ContentValues cv = new ContentValues(); 
    cv.put(Contactsnew.TITLE, title); 
    cv.put(Contactsnew.CATEGORY, category); 
    cv.put(Contactsnew.userId, _id1); 

    db = sqlHp.getWritableDatabase(); 
    db.insert(Contactsnew.TABLE2, null, cv); 
    //db.close(); 

} 

public void updateContact(long _id, int _id1, String title, 
     String category) { 
    ContentValues cv = new ContentValues(); 
    cv.put(Contactsnew.TITLE, title); 
    cv.put(Contactsnew.CATEGORY, category); 
    cv.put(Contactsnew.userId, _id1); 
    //cv.put(Contactsnew.userid, _id); 
    //cv.put(Contactsnew.IMAGE, blob); 

    db = sqlHp.getWritableDatabase(); 
    db.update(Contactsnew.TABLE2, cv, Contactsnew.userid + "=_id" + " AND " + Contactsnew.userId + "=_id1", null); 
    //db.update(Contactsnew.TABLE2, cv, Contactsnew.userid + "=_id", null); 
    db.update(Contactsnew.TABLE2, cv, Contactsnew.TITLE + "=title", null); 
    db.close(); 
} 

public Cursor getAllContacts() { 
    db = sqlHp.getReadableDatabase(); 
    cur = db.query(Contactsnew.TABLE2, null, "_id1=" + GetSet.getUserId(), 
      null, null, null, "title"); 
    return cur; 
public static Cursor fetchAllvalues1() { 

     Cursor mCursor = db.query(Contactsnew.TABLE2, new String[] {Contactsnew.userid,Contactsnew.userId,Contactsnew.CATEGORY,Contactsnew.TITLE}, 
     null, null, null, null, null); 

     if (mCursor != null) { 
     mCursor.moveToFirst(); 
     } 
     return mCursor; 
    } 
public static Cursor fetchCountriesByName1(String inputText) throws SQLException { 
     Log.w(TAG, inputText); 
     Cursor mCursor = null; 
     if (inputText == null || inputText.length() == 0) { 
     mCursor = db.query(Contactsnew.TABLE2, new String[] {Contactsnew.userid,Contactsnew.userId,Contactsnew.CATEGORY,Contactsnew.TITLE}, 
     null, null, null, null, null); 

     } 
     else { 
     mCursor = db.query(true, Contactsnew.TABLE2, new String[] {Contactsnew.userid,Contactsnew.userId,Contactsnew.CATEGORY,Contactsnew.TITLE}, 
     Contactsnew.userId + " AND " +Contactsnew.TITLE + " like '%" + inputText + "%'", null, 
     null, null, null, null); 
     } 
     if (mCursor != null) { 
     mCursor.moveToFirst(); 
     } 
     return mCursor; 

    }

究竟是什麼問題？ – Pavlos

如果你使用更多的textview，那麼它會搜索所有。爲此，您必須在適配器類中編寫自己的filter（）方法。 –

我的問題是它的過濾所有列表中存在的不同的ID，我想只搜索特定的ID列表!!例如：如果假設我登錄爲ID：86我會添加一些數據，它會顯示爲列表，同時搜索它顯示其他ID中出現的所有內容！ – ajey

在你sqlitedatabase我已經編輯了一些代碼試試這個！

public static Cursor fetchAllvalues1() { 

     Cursor mCursor = db.query(Contactsnew.TABLE02, new String[] {Contactsnew.userid,Contactsnew.userId,Contactsnew.CATEGORY,Contactsnew.TITLE}, 
     null, null, null, null, null); 

     if (mCursor != null) { 
     mCursor.moveToFirst(); 
     } 
     return mCursor; 
    } 
public static Cursor fetchCountriesByName1(String inputText) throws SQLException { 
     Log.w(TAG, inputText); 
     Cursor mCursor = null; 
     if (inputText == null || inputText.length() == 0) { 
     mCursor = db.query(Contactsnew.TABLE02, new String[] {Contactsnew.userid,Contactsnew.userId,Contactsnew.CATEGORY,Contactsnew.TITLE}, 
     null, null, null, null, null); 

     } 
     else { 
      mCursor=db.rawQuery(" SELECT * FROM "+ Contactsnew.TABLE02 + " WHERE " 
        + Contactsnew.userId + " = " + GetSet.getUserId() + " AND " + Contactsnew.TITLE + 
          " LIKE ? " ,new String []{inputText +"%"}); 
     } 
     if (mCursor != null) { 
     mCursor.moveToFirst(); 
     } 
     return mCursor; 

    }
