我正在设计一个用于消息传递的应用程序。我正在使用 sqlite 数据库来存储用户信息，但我收到了这个错误 logcat。

pendingintents 是我给我的桌子起的名字。

这是我的 sqlite 助手类

public class SQLLiteOpenHelper extends SQLiteOpenHelper {

 public static final String TABLE_PENDINGINTENT = "pendingintents";
  public static final String COLUMN_ID = "_id";
  public static final String COLUMN_HOUR = "hour";
  public static final String COLUMN_MINUTES = "minutes";
  public static final String COLUMN_SECONDS = "seconds";
  public static final String COLUMN_YEAR = "year";
  public static final String COLUMN_MONTH = "month";
  public static final String COLUMN_DAY = "day";
  public static final String COLUMN_FREQUENCY = "frequency";
  public static final String COLUMN_NUMBERTOSEND = "numbertosend";
  public static final String COLUMN_RECEIVERNAME = "receivername";
  public static final String COLUMN_MESSAGE = "message";
      private static final String DATABASE_NAME = "PendingIntentDatabase.db";
      private static final int DATABASE_VERSION = 1;


      private static final String DATABASE_CREATE = "CREATE TABLE " + TABLE_PENDINGINTENT + "(" + COLUMN_ID + " INTEGER PRIMARY KEY , " + COLUMN_HOUR +" INTEGER, " + COLUMN_MINUTES + " INTEGER, " + COLUMN_SECONDS + " INTEGER, " + COLUMN_YEAR + " INTEGER, " + COLUMN_MONTH + " INTEGER, " + COLUMN_DAY + " INTEGER, " + COLUMN_FREQUENCY + " String, " + COLUMN_NUMBERTOSEND + " String, " + COLUMN_RECEIVERNAME + " String, " + COLUMN_MESSAGE + " String " + ");";

public SQLLiteOpenHelper(Context context, String name,
        CursorFactory factory, int version) {
    super(context, DATABASE_NAME, factory, DATABASE_VERSION);
    // TODO Auto-generated constructor stub
}

@Override
public void onCreate(SQLiteDatabase arg0) {
    // TODO Auto-generated method stub
    arg0.execSQL(DATABASE_CREATE);
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    // TODO Auto-generated method stub
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_PENDINGINTENT);
    onCreate(db);
}

}

数据库插入在这里完成'

              public ValueInsertion InitializePendingIntents(int id, int hour, int mins, int secs, int year, int month, int day, String frequency, String number, String name, String message )
  {
      ContentValues val= new ContentValues();
      val.put(SQLLiteOpenHelper.COLUMN_ID, id);
      val.put(SQLLiteOpenHelper.COLUMN_HOUR, hour);
      val.put(SQLLiteOpenHelper.COLUMN_MINUTES, mins);
      val.put(SQLLiteOpenHelper.COLUMN_SECONDS, secs);
      val.put(SQLLiteOpenHelper.COLUMN_YEAR, year);
      val.put(SQLLiteOpenHelper.COLUMN_MONTH, month);
      val.put(SQLLiteOpenHelper.COLUMN_DAY, day);
      val.put(SQLLiteOpenHelper.COLUMN_FREQUENCY, frequency);
      val.put(SQLLiteOpenHelper.COLUMN_NUMBERTOSEND, number);
      val.put(SQLLiteOpenHelper.COLUMN_RECEIVERNAME, name);
      val.put(SQLLiteOpenHelper.COLUMN_MESSAGE, message);

      database.insert(SQLLiteOpenHelper.TABLE_PENDINGINTENT, null,val);

      Cursor cursor = database.query(SQLLiteOpenHelper.TABLE_PENDINGINTENT,
                allColumns, SQLLiteOpenHelper.COLUMN_ID + " = " + id, null,
                null, null, null);

      cursor.moveToFirst();
      ValueInsertion newPendingIntent = cursorForPI(cursor);
      cursor.close();
      return newPendingIntent;
  }

您还需要确保执行创建表的 sql 语句：

DATABASE_CREATE = "CREATE TABLE " + TABLE_PENDINGINTENT + "(" + COLUMN_ID + " INTEGER PRIMARY KEY , " + COLUMN_HOUR +" INTEGER, " + COLUMN_MINUTES + " INTEGER, " + COLUMN_SECONDS + " INTEGER, " + COLUMN_YEAR + " INTEGER, " + COLUMN_MONTH + " INTEGER, " + COLUMN_DAY + " INTEGER, " + COLUMN_FREQUENCY + " String, " + COLUMN_NUMBERTOSEND + " String, " + COLUMN_RECEIVERNAME + " String, " + COLUMN_MESSAGE + " String " + ");";

从下面的陈述中可以很清楚地看到：

05-19 22:24:00.211: E/SQLiteLog(8815): (1) no such table: pendingintents

该表未创建 - 无论出于何种原因。澄清一下，如果升级正在执行，该表将被删除 - 之后您没有重新创建语句......

程序点。您命名创建表 DATABASE_CREATE的字符串。它应该是create_table_pendingintents，或者不是像DATABASE_CREATE

编辑

如果您在执行 sql 期间遇到错误，请尝试将您的代码包装在错误陷阱中 - 建议您在执行 db 操作时随时使用：

try{
    db.execSQL(DATABASE_CREATE_MY_TABLE);                                   
}catch(SQLiteException e){
   Log.v(CLASS,"Error: [{"+CLASS+"}{database}[onCreate] Exception: "+e.getMessage());
}
