我試圖將數據插入到數據庫，但得到的問題，錯誤說：android.database.sqlite.SQLiteDatatypeMismatchException：數據類型不匹配（代碼20）
android.database.sqlite.SQLiteDatatypeMismatchException: datatype mismatch (code 20)
ERROR1說： -
com.example.db.myDBClass.InsertData(myDBClass.java:51)
線路是： -
long rows = db.insert(TABLE_MEMBER, null, Val);
誤差2說： -
com.example.db.UploadActivity.InsertDatas(UploadActivity.java:271)
線路是： -
long saveStatus = myDb.InsertData(editImageName.getText().toString(),editPersonName.getText().toString(),
editPersonaEmail.getText().toString(), editPersonTelephone.getText().toString());
誤差3說： -
com.example.db.UploadActivity$3.onClick(UploadActivity.java:429)
線路是： -
InsertDatas();
日誌： -

試着用成員表中的列代替TEXT（100）類型的VARCHAR（100）。 –
在UploadActivity.java文件中，第271＆429行是什麼... –
@VeaceslavGaidarji通過使用VARCHAR（100）仍然得到相同的錯誤 – user3024524
