我写了简单的DataBaseHelper来在android中使用SQlite。在创建类之后：
public class DatabaseHandler extends SQLiteOpenHelper{
private static String DB_PATH = "";
private static final String DATABASE_NAME = "tsms";
private static String RECEIVE_FIELDS_TABLE = "ReceiveFields";
private static final String COLUMN_ID = "id";
private static final String COLUMN_LASTID = "lastId";
private static final String COLUMN_SMSNUMBER = "smsNumber";
private static final String COLUMN_MOBILENUMBER = "mobileNumber";
private static final String COLUMN_SENDERNAME = "senderName";
private static final String COLUMN_SMSBODY = "smsBody";
private static final String COLUMN_RECEIVEDATE = "receiveDate";
private static final int DATABASE_VERSION = 1;
private SQLiteDatabase mDataBase;
/* UPDATE DATABASE_CREATE FIELD*/
private static final String DATABASE_CREATE = "CREATE TABLE " + RECEIVE_FIELDS_TABLE + "("
+ COLUMN_ID + " INTEGER UNIQUE , "
+ COLUMN_LASTID + " INTEGER UNIQUE , "
+ COLUMN_SMSNUMBER + " VARCHAR UNIQUE , "
+ COLUMN_MOBILENUMBER + " VARCHAR , "
+ COLUMN_SENDERNAME + " VARCHAR , "
+ COLUMN_SMSBODY + " TEXT , "
+ COLUMN_RECEIVEDATE + " VARCHAR , PRIMARY KEY (" + COLUMN_ID + ", " + COLUMN_LASTID + ", " + "))";
private Context context;
public DatabaseHandler(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase sqLiteDatabase) {
sqLiteDatabase.execSQL(DATABASE_CREATE);
}
@Override
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int oldVersion, int newVersion) {
sqLiteDatabase.execSQL("DROP TABLE IF EXISTS " + RECEIVE_FIELDS_TABLE);
// Create tables again
onCreate(sqLiteDatabase);
}
// Adding new fields
public void addToReceived(ReceiveFields fields) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(COLUMN_LASTID, fields.getLastId()); // ReceiveFields last ID
values.put(COLUMN_MOBILENUMBER, fields.getMobileNumber()); // ReceiveFields Mobile Number
values.put(COLUMN_SENDERNAME, fields.getSenderName()); // ReceiveFields Mobile Number
values.put(COLUMN_SMSBODY, fields.getSmsBody()); // ReceiveFields Mobile Number
values.put(COLUMN_SMSNUMBER, fields.getSmsNumber()); // ReceiveFields Mobile Number
values.put(COLUMN_MOBILENUMBER, fields.getMobileNumber()); // ReceiveFields Mobile Number
values.put(COLUMN_RECEIVEDATE, String.valueOf(fields.getReceiveDate())); // ReceiveFields Mobile Number
// Inserting Row
db.insert(RECEIVE_FIELDS_TABLE, null, values);
db.close(); // Closing database connection
}
}
我以这种方式错误地插入数据库：
db.addToReceived(new ReceiveFields(
Long.valueOf(str1[0]),
str1[1],
str1[2],
URLDecoder.decode(str1[3], "UTF-8"),
URLDecoder.decode(str1[4], "UTF-8"),
ct.getGregorianDate()));
Log.i结果：
29904757 30007227 00120504001 00120504001 sssasaS 2014/8/3

答案 0 :(得分：2)
检查这些事情，可能由以下原因引起：
1-您没有将COLUMN_ID添加到values，因此它为空。
2 - COLUMN_ID和COLUMN_LASTID不是UNIQUE (clear your database or android app data , maybe it stored in your db first time you ran it and now again you want to add you can not because it is not unique now, every time you run, your db is in memory and it is not clread, in order to clear it you must remove app data or run delete SQL statement)
所以我建议你看看你的DB文件，如果你使用eclipse试试这个：

3 - COLUMN_ID和COLUMN_LASTID不是int我的意思是fields.getLastId()可能会返回String
准确检查你的桌子定义和你要插入的值!!!

您似乎正在尝试将null作为smsBody插入，但您的表格不允许您执行此操作，因为此列有NOT NULL约束。
