请解释一下为什么会这样..告诉我解决方案
最佳答案
来自您的日志:
Caused by: android.database.sqlite.SQLiteException:
AUTOINCREMENT is only allowed on an INTEGER PRIMARY KEY
从您的代码中:
@Override
public void onCreate(SQLiteDatabase db) {
String SQL_String = "CREATE TABLE " + TABLE_NAME + "("
+COL_1+"INTEGER PRIMARY KEY AUTOINCREMENT,"
+COL_2+" TEXT, "
+COL_3 +"VARCHAR(20),"
您的字符串缺少空格，因此它不是有效的语法，请尝试:
@Override
public void onCreate(SQLiteDatabase db) {
String SQL_String = "CREATE TABLE " + TABLE_NAME + "("
+ COL_1 + " INTEGER PRIMARY KEY AUTOINCREMENT, "
+ COL_2 + " TEXT, "
+ COL_3 + " VARCHAR(20), "
