I do an activation class in which authentication. I have an error:
Failed to read row 3, column -1 from a CursorWindow which has 10 rows, 3 columns. Failed to read row 3, column -1 from a CursorWindow which has 10 rows, 3 columns. .. .. .. Failed to read row 9, column -1 from a CursorWindow which has 10 rows, 3 columns.
Here is the activation code:
package com.example.dbapp; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.util.Log; import android.view.View; import android.view.View.OnClickListener; import android.widget.ArrayAdapter; import android.widget.Button; import android.widget.EditText; import android.widget.ListView; import android.widget.Toast; import com.orm.SugarContext; import java.lang.reflect.Array; import java.util.ArrayList; import java.util.List; public class MainActivity extends Activity implements OnClickListener { final String LOG_TAG = "myLogs"; Button btnAdd, btnRead, btnClear; Button backToInReg,register; EditText etName, etEmail; ArrayAdapter<Book> arrayAdapter; ListView listView; Book book = new Book(); /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); btnAdd = (Button) findViewById(R.id.log); btnAdd.setOnClickListener(this); etName = (EditText) findViewById(R.id.login); etEmail = (EditText) findViewById(R.id.password); register = (Button) findViewById(R.id.reg); register.setOnClickListener(this); listView = (ListView) findViewById(R.id.listView); List<Book> list = Book.listAll(Book.class); arrayAdapter = new ArrayAdapter<Book>(MainActivity.this,android.R.layout.simple_list_item_1,list); listView.setAdapter(arrayAdapter); } @Override public void onClick(View v) { switch (v.getId()){ case R.id.log: String login = etName.getText().toString(); String password = etEmail.getText().toString(); List<Book> list = Book.listAll(Book.class); for(int i = 0;i<list.size();i++){ String ds = list.get(i).login; if(list.get(i).login==login && list.get(i).password==password){ Intent intent = new Intent(MainActivity.this,Activity_Registration.class); startActivity(intent); }else { Toast.makeText(getApplicationContext(),"Error! Login or password incorrect!",Toast.LENGTH_SHORT).show(); } } break; case R.id.reg: break; } } } Question: Do I check the login and password from the database correctly?
