java - android.database.sqlite.SQLiteDatatypeMismatchException : datatype mismatch (code 20)

Question

我正在尝试将数据插入数据库，但出现问题，错误提示:

android.database.sqlite.SQLiteDatatypeMismatchException: datatype mismatch (code 20)

错误1说:-

com.example.db.myDBClass.InsertData(myDBClass.java:51)

行是:-

long rows = db.insert(TABLE_MEMBER, null, Val);

错误2说:-

com.example.db.UploadActivity.InsertDatas(UploadActivity.java:271)

行是:-

long saveStatus = myDb.InsertData(editImageName.getText().toString(),editPersonName.getText().toString(),
                editPersonaEmail.getText().toString(), editPersonTelephone.getText().toString());

Error3 说:-

com.example.db.UploadActivity$3.onClick(UploadActivity.java:429)

行是:-

InsertDatas();
