}
答案 0 :(得分：0)
更改以下行 -
public static final String DB_Query = "create table " + DB_Table1 + "("
+Sms_Address+" text not null, "+Sms_Body+" text not null, "
+Status_Msg+" integer)";
到 -
String Status_Msg = "status_msg";
public static final String DB_Query = "create table " + DB_Table1 + "("
+Sms_Address+" text not null, "+Sms_Body+" text not null, "
+Status_Msg+" integer default 1)";
答案 1 :(得分：0)
public static final String DATABASE_NAME = "student.db";
public static final int VERSION = 1;
public static final String TABLE_NAME = "tbl_student";
public static final String S_ID = "s_id";
public static final String S_NAME = "s_name";
public static final String S_GENDER = "s_gender";
public static final String CREATE_TABLE = "create table "+TABLE_NAME+"("
+S_ID+ " integer primary key autoincrement, " +S_NAME+ " text not null, " +S_GENDER+ " text not null )";
答案 2 :(得分：-2)
可能需要一个空间“（”。
public static final String DB_Query =“create table”+ DB_Table1 +“（”+ Sms_Address +“text not null，”+ Sms_Body +“text not null，”+ Status_Msg +“integer）”;
