Question

我有以下代码：

    ArrayList NumList = getIntent().getParcelableArrayListExtra ("name");
    ArrayList<String> results = new ArrayList<String>();
    SQLiteDatabase sampleDB = null;

    try {
        sampleDB =  this.openOrCreateDatabase(SAMPLE_DB_NAME, MODE_PRIVATE, null);

        sampleDB.execSQL("CREATE TABLE IF NOT EXISTS " +
                SAMPLE_TABLE_NAME +
                " (FirstName VARCHAR);");

        sampleDB.execSQL("INSERT INTO " +
                SAMPLE_TABLE_NAME +
                " Values (NumList);");

我要做的是将NumList传递到表中。上面的代码显示错误，说“没有这样的列：NumList”“我如何通过这些信息？

Answer 1

试试这个：

sampleDB.execSQL("INSERT INTO " +
            SAMPLE_TABLE_NAME +
            " ( FirstName ) Values ('"+NumList+"');");

Answer 2

试试这个：

for(String str: NumList){
sampleDB.execSQL("INSERT INTO " +
            SAMPLE_TABLE_NAME +
            " ( FirstName ) Values ('"+str+"');");
}

将一个arraylist传递给SQLite数据库
