Android上的即时通讯新。 我有一些麻烦与数据库中插入语句，当运行应用程序IM的价值还没有被插入。 请有人能帮助.. 

public class DatabaseAdapter extends SQLiteOpenHelper {
// Database attributes
public static final String DB_NAME = "MoneyManagerSystemTr";
public static final int DB_VERSION = 1;

// Table attributes

public static final String TABLE_ACCOUNT = "account_table";

//Account Table
public static final String KEY_BANKNAME ="bankname";
public static final String KEY_TYPE = "type";
public static final String KEY_ACCNUM = "accnum";
public static final String KEY_BALANCE = "balance";
public static final String KEY_EXPIRYDATE = "expirydate";

@Override
public void onCreate(SQLiteDatabase db) {


    String AccountTable = "create table if not exists " + TABLE_ACCOUNT + " ( " + BaseColumns._ID + " integer primary key autoincrement, " 
            + KEY_BANKNAME + " text not null, "
            + KEY_TYPE + " text, "
            + KEY_ACCNUM + " text, "
            + KEY_BALANCE + " text, "
            + KEY_EXPIRYDATE + " text);";

    db.execSQL(AccountTable);

String ROW1 = "INSERT INTO " + TABLE_ACCOUNT + " Values ('Cash','','',0, '');";
    db.execSQL(ROW1);

    String ROW2 = "INSERT INTO " + TABLE_ACCOUNT + " Values ('Bank Account','','',0, '');";
    db.execSQL(ROW2);

    String ROW3 = "INSERT INTO " + TABLE_ACCOUNT + " Values ('Credit Card','','',0, '');";
    db.execSQL(ROW3);

Answer 1:

从插入语句删除分号和0周围添加引号： 

String ROW1 = "INSERT INTO " + TABLE_ACCOUNT + " ("
              + KEY_BANKNAME + ", " + KEY_TYPE + ", "
              + KEY_ACCNUM + ", " + KEY_BALANCE + ", "
              + KEY_EXPIRYDATE + ") Values ('Cash', '', '', '0', '')";
db.execSQL(ROW1);

更重要的是，注意在建议execSQL（）和使用插入（）来代替。



Answer 2:

您可以使用ContentValues插入到你的数据库。 

SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(COL_NAME, VALUE); 
values.put(COL_NAME, VALUE);

// Inserting Row
db.insert(YOUR_TABLE, null, values);


Answer 3:

1）DatabaseHelper 

public class DatabaseHelper extends SQLiteOpenHelper {
public static final String TAG = "DatabaseHelper";
public static final String DATABASE_NAME = "test.db";


public static final String TABLE_NAME_2 = "updates";


private Context context;
public static final String Trigger = "fk_insert_state";
public static final int DATABASE_VERSION = 2;



public static final String TABLE_2_CREATE = "Create table "
        + TABLE_NAME_2
        + " (_id integer primary key autoincrement, w_id text, title text, des text, date_text text, image_url text, video_url text,link text, con_type text, con_source text, timestamp integer, UNIQUE (_id) ON CONFLICT REPLACE)";


private static DatabaseHelper databasehelper;

public static DatabaseHelper getInstance(Context context) {
    if (databasehelper == null)
        databasehelper = new DatabaseHelper(context);
    return databasehelper;

}

public DatabaseHelper(Context context) {
    super(context, DATABASE_NAME, null, DATABASE_VERSION);
    this.context = context;

}

@Override
public void onCreate(SQLiteDatabase db) {


    db.execSQL(TABLE_2_CREATE);

}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    Util.customLog("Upgrade "
            + "Database has been updraded but we have'nt do anything");
}

 }

2）DatabaseOperation 

 import android.content.ContentValues;

 public interface DatabaseOperation {
 public long insert(Object object);
 public int update(Object object);
 public int delete(Object object);
 ContentValues getContentValues(Object object);
 }

3）数据类

public class UpdateData {

private int _id;
private String w_id;
private long timestamp;

public UpdateData(int _id, String w_id,  long timestamp) {
    super();
    this._id = _id;
    this.w_id = w_id;
    this.timestamp = timestamp;

}



public String getW_id() {
    return w_id;
}

public void setW_id(String w_id) {
    this.w_id = w_id;
}

public long getTimestamp() {
    return timestamp;
}

public void setTimestamp(long timestamp) {
    this.timestamp = timestamp;
}

public UpdateData() {
    super();
}

public String TableName() {
    return "updates";
}

public int get_id() {
    return _id;
}

public void set_id(int _id) {
    this._id = _id;
}

}

4）DataImpl 

 import android.content.ContentValues;
 import android.content.Context;
 import android.database.Cursor;
 import android.database.sqlite.SQLiteDatabase;

public class UpdateImpl implements DatabaseOperation {
SQLiteDatabase database;

public UpdateImpl(Context context) {
    DatabaseHelper databasehelper = DatabaseHelper.getInstance(context);
    database = databasehelper.getWritableDatabase();

}

@Override
public long insert(Object object) {
    UpdateData table = (UpdateData) object;
    long result = database.insert(table.TableName(), null,
            this.getContentValues(object));
    return result;
}

public void insertAll(ArrayList<UpdateData> objects){
    database.beginTransaction();
    for (UpdateData object : objects) {
        UpdateData table = object;
        database.insert(table.TableName(), null,
                this.getContentValues(object));
    }
    database.setTransactionSuccessful();
    database.endTransaction();
}

@Override
public int update(Object object) {
    UpdateData table = (UpdateData) object;
    String[] whereArgs = { String.valueOf(table.get_id()) };
    return update(object, "_id = ?", whereArgs);
}

public int update(Object object, String whereClause, String[] whereArgs) {
    UpdateData table = (UpdateData) object;
    int result = database.update(table.TableName(),
            this.getContentValues(object), whereClause, whereArgs);
    Util.customLog("Update Result - " + result);
    return result;
}

@Override
public int delete(Object object) {
    UpdateData table = (UpdateData) object;
    String[] whereArgs = { String.valueOf(table.get_id()) };
    int result = database.delete(table.TableName(), "_id = ?", whereArgs);
    Util.customLog("Delete Result - " + result);
    return result;
}

@Override
public ContentValues getContentValues(Object object) {
    UpdateData table = (UpdateData) object;
    ContentValues contentValues = new ContentValues();
    // contentValues.put("_id", table.get_id());
    contentValues.put("w_id", table.getW_id());
    contentValues.put("timestamp", table.getTimestamp());

    return contentValues;

}

public List getAll() {
    List<UpdateData> itemList = new ArrayList<UpdateData>();

            table.setW_id(cursor.getString(cursor.getColumnIndex("w_id")));
            table.setTimestamp(cursor.getLong(cursor
                    .getColumnIndex("timestamp")));

            itemList.add(table);
        } while (cursor.moveToNext());
        cursor.close();
    } else {

                        position).toString()));

5）WebService的响应

   protected class GetJury extends AsyncTask<String, String, String> {

    @Override
    protected void onPreExecute() {
        super.onPreExecute();

        // pDialog.setMessage("Please wait...");

Answer 4:

更改此行。 给在引号0

你declate KEY_BALANCE为文本，但你在此字段中输入整数值。 这是y您也越来越错误 

 public long insert_table(String BANKNAME,String TYPE,
            String ACCNUM, String BALANCE,
            String EXPIRYDATE) {

    this.insertStmt.bindString(1, BANKNAME);
    this.insertStmt.bindString(2, TYPE);
    this.insertStmt.bindString(3, ACCNUM);
    this.insertStmt.bindString(4, BALANCE);
    this.insertStmt.bindString(5, EXPIRYDATE);

    return this.insertStmt.executeInsert();

    }

调用此方法，你正试图插入值

DataHelper dh = new DataHelper(this);
dh.insert_table("Bank Account","","","0","");
