我跑这个程序的时候遇到了数据库无法成功创建的问题

[deqianzou]

我跑程序的时候发现无法创建数据库，具体错误如下
Error inserting title=ribfj content=runs to android.database.sqlite.SQLiteException: no such table: notepad (code 1): , while compiling: INSERT INTO notepad(title,content) VALUES (?,?) at android.database.sqlite.SQLiteConnection.nativePrepareStatement(Native Method) at android.database.sqlite.SQLiteConnection.acquirePreparedStatement(SQLiteConnection.java:889) at android.database.sqlite.SQLiteConnection.prepare(SQLiteConnection.java:500) at android.database.sqlite.SQLiteSession.prepare(SQLiteSession.java:588) at android.database.sqlite.SQLiteProgram.<init>(SQLiteProgram.java:58) at android.database.sqlite.SQLiteStatement.<init>(SQLiteStatement.java:31) at android.database.sqlite.SQLiteDatabase.insertWithOnConflict(SQLiteDatabase.java:1472) at android.database.sqlite.SQLiteDatabase.insert(SQLiteDatabase.java:1343) at com.example.lab126.sqlite_notepad_02.EditActivity.onClick(EditActivity.java:49) at android.view.View.performClick(View.java:6219) at android.view.View$PerformClick.run(View.java:24482) at android.os.Handler.handleCallback(Handler.java:769) at android.os.Handler.dispatchMessage(Handler.java:98) at android.os.Looper.loop(Looper.java:164) at android.app.ActivityThread.main(ActivityThread.java:6540) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.Zygote$MethodAndArgsCaller.run(Zygote.java:240) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:767)

感觉很奇怪，这个问题困扰我两天了。
