は、どのように私はなりますが、ユーザー

Question

私はsqliteの点では、次のSQLコードをしたい

によって挿入された特定の文字で始まるのSQLiteデータベース内の列から値を選択することができます（ 1） "のように" 近い：構文エラー

マイコード：

public class Datalist extends ListActivity{ 

public String id1; 
RegistrationAdapter adapter_ob; 
DBhandler helper_ob; 
SQLiteDatabase db_ob; 
ListView nameList; 
Cursor cursor; 
public ListView listView; 

ArrayList<HashMap<String, String>> list = new ArrayList(); 
private ArrayList<String> results = new ArrayList<String>(); 
String tableName = DBhandler.TABLE_NAME; 
String n=DBhandler.KEY_NAME; 
String m=DBhandler.KEY_MEAN; 
private SQLiteDatabase newDB; 
protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     //setContentView(R.layout.list); 

     id1 = getIntent().getStringExtra(config.TAG_ID); 
     openAndQueryDatabase(); 
     displayResultList(); 


    } 
private void displayResultList() { 
    // TODO Auto-generated method stub 
    //TextView tView = new TextView(this); 
    //tView.setText("This data is retrieved from the database and only 4 " + 
    //"of the results are displayed"); 
    //getListView().addHeaderView(tView); 

    setListAdapter(new ArrayAdapter<String>(this, 
    android.R.layout.simple_list_item_1, results)); 
    getListView().setTextFilterEnabled(true); 

} 
private void openAndQueryDatabase() { 
    // TODO Auto-generated method stub 
    try { 
     DBhandler dbHelper = new DBhandler(this.getApplicationContext()); 
     newDB = dbHelper.getWritableDatabase(); 
     Cursor c = newDB.rawQuery("SELECT _name, _mean FROM " + 
     tableName + "where _name like'" +id1+ "%'" , null); 

     if (c != null) { 
     if (c.moveToFirst()) { 
     do { 
     //Integer id=c.getInt(c.getColumnIndex("_id")); 
     String Name = c.getString(c.getColumnIndex("_name")); 
     String mean= c.getString(c.getColumnIndex("_mean")); 

     /* HashMap<String, String> baby = new HashMap(); 
     //baby.put(config.TAG_ID, id); 
     baby.put(config.TAG_NAME, Name); 
     baby.put(config.TAG_MEAN1, mean); 
     list.add(baby);*/ 
     results.add("" + Name + "" 
       + "" + mean); 

     }while (c.moveToNext()); 
     } 
     } 
     } catch (SQLiteException se) { 
     Log.e(getClass().getSimpleName(), "Could not create or Open the database"); 
     } 
    finally { 
     if (newDB != null) 
     newDB.execSQL("DELETE FROM " + tableName); 
     newDB.close(); 
     //listView.setAdapter(new SpecialAdapter(this, list, R.layout.list_item, new String[]{config.TAG_NAME, config.TAG_MEAN1}, new int[]{R.id.name, R.id.mean1})); 
     } 
    //listView.setAdapter(new SpecialAdapter(this, list, R.layout.list_item, new String[]{config.TAG_NAME, config.TAG_MEAN1}, new int[]{R.id.name, R.id.mean1})); 

     } 

} 

誰が...事前に

あなたは試してみました。この...

public Cursor getBabyName(String query) { 
     return db.query(DbHelper.NAME_TABLE, NAME_FIELDS, 
       DbHelper.BABY_NAME+ " like '" + query + "%'", null, 
       null, null, null, null); 
    }
