这里是我尝试在DB

long chk = 0; 
SQLiteDatabase db1 = userInstance.getWritableDatabase(); 
ContentValues values = new ContentValues(); 

for (int i = 0; i < p; i++) // p is the max limit 
{ 
    values.put(manageAppDBHelper.DBAppName[i], AppName[i]); // manageAppDBHelper 
                  // is a 
                  // class 
} 

chk = db1.insert(manageAppDBHelper.TABLE2, null, values); 
Log.v("check", chk + ""); 
if (chk != -1) { 
    Toast.makeText(getBaseContext(), "DATABASE updated ... ", 
      Toast.LENGTH_LONG).show(); 
} 
db1.close(); // Closing database connection 

/** Helper to the database, manages versions and creation */ 
public class manageAppDBHelper extends SQLiteOpenHelper { 
private static final int DATABASE_VERSION = 1; 
// Table name 
public static final String TABLE2 = "appliances"; 
private static final String DATABASE_NAME = "mbpto_user8.db"; 

public static final String[] DBAppName = { "Appliance1", "Appliance2", 
     "Appliance3", "Appliance4", "Appliance5", "Appliance6", 
     "Appliance7", "Appliance8", "Appliance9", "Appliance10", 
     "Appliance11", "Appliance12", "Appliance13", "Appliance14", 
     "Appliance15", "Appliance16", "Appliance17", "Appliance18", 
     "Appliance19", "Appliance20", "Appliance21", "Appliance22", 
     "Appliance23", "Appliance24", "Appliance25", "Appliance26", 
     "Appliance27", "Appliance28", "Appliance29", "Appliance30" }; // 30nullvalues 

public manageAppDBHelper(Context context) { 
    super(context, DATABASE_NAME, null, DATABASE_VERSION); 
} 

@Override 
public void onCreate(SQLiteDatabase db) { 

    String sql = "create table " + TABLE2 + "(" + BaseColumns._ID 
      + " integer primary key autoincrement, " + DBAppName[0]

    Log.d("Updating Appliance Database", "onCreate: " + sql); 
    db.execSQL(sql);

@Override

    Log.d("Adding Appliance Database", "onUpgrade : " + sql); 
    if (sql != null) 
     db.execSQL(sql); 
} 
}

你得到插入错误的行中的数据得到的冲突进行保存。试试这些，并用这些替换您的插入代码::

chk = db1.insertWithOnConflict(manageAppDBHelper.TABLE2, null, values, CONFLICT_IGNORE); 

希望这些可能会有所帮助！
