Question

您好我在向我的数据库添加数据时遇到此错误但我无法弄清楚原因。我认为问题出在addData（） - Method中，但是到目前为止我没有尝试修复它。

“E / SQLiteLog：（1）”Aktivität“附近：语法错误”

以及：

“android.database.sqlite.SQLiteException：near”Aktivität“：语法错误（代码1）:,编译时：INSERT INTO MedDatenTabelle（Schmerz，Broteinheiten，Messzeit，Wasser，Diastole，Müdigkeit，Puls，Symptom，letzteAktivität ，Gewicht，Kalorien，Bemerkungen，Systole，Temperatur，Blutzucker）VALUES（？，？，？，？，？，？，？，？，？，？，？，？，？，？，？）“

Answer 1

您的错误在此处（字段名称中的空格，没有限定符）：

private static final String KEY_AKTI = "letzte Aktivität"

试

private static final String KEY_AKTI = "letzte_Aktivität"

代替。

如果空格强制，请尝试：

private static final String KEY_AKTI = "'letzte Aktivität'"

或者

private static final String KEY_AKTI = "[letzte Aktivität]"

或者

private static final String KEY_AKTI = "`letzte Aktivität`"
