这里是我的registrationForm.java文件的代码段
public class registrationForm extends ActionBarActivity implements View.OnClickListener {
EditText e1, e2, e3, e4, e5, e6, e7;
Button b1, b2;
public static final Pattern EMAIL = Pattern.compile("[a-zA-Z0-9+._%-+]{1,100}" + "@" + "[a-zA-Z0-9][a-zA-Z0-9-]{0,10}" + "(" + "."
+ "[a-zA-Z0-9][a-zA-Z0-9-]{0,20}" + ")+");
public static final Pattern FirstNAME = Pattern.compile("[a-zA-Z0-9]{1,10}");
public static final Pattern LastNAME = Pattern.compile("[a-zA-Z0-9]{1,10}");
public static final Pattern PASSWORD = Pattern.compile("[0-9]{4,16}");
public static final Pattern PHONE = Pattern.compile("[0-9]{10}");
public static final Pattern ADD = Pattern.compile("[A-Z a-z 0-9]{1,50}");
dbHelper db;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_registration_form);
e1 = (EditText) findViewById(R.id.editText);
e2 = (EditText) findViewById(R.id.editText2);
e3 = (EditText) findViewById(R.id.editText3);
e4 = (EditText) findViewById(R.id.editText4);

b1 = (Button) findViewById(R.id.button);
b2 = (Button) findViewById(R.id.button2);
b1.setOnClickListener(this);
b2.setOnClickListener(this);
db=new dbHelper(this);
}
@Override
public void onClick(View v) {
String firstName = e1.getText().toString();
String lastName = e2.getText().toString();
String password = e3.getText().toString();
String confirm = e4.getText().toString();
String email = e5.getText().toString();
String phone = e6.getText().toString();

if (v == b1) {

}

}
if (!confirm.equals(password)) {

}
else{

Toast.makeText(getApplicationContext(), "Account Successfully Created ", Toast.LENGTH_SHORT).show();
}
}
if (v == b2) {
Intent i1 = new Intent(this, Login.class);
startActivity(i1);
}
}
private boolean CheckEmail(String email) {
return EMAIL.matcher(email).matches();
}
private boolean CheckPassword(String password) {
return PASSWORD.matcher(password).matches();
}
private boolean CheckFirst_name(String firstName) {
return FirstNAME.matcher(firstName).matches();
}
private boolean CheckLast_name(String lastName) {
return LastNAME.matcher(lastName).matches();
}
private boolean CheckPhone(String phone) {
return PHONE.matcher(phone).matches();
}
private boolean CheckAddress(String add) {
return ADD.matcher(add).matches();
}
}
这是dbHelper类文件代码：
public class dbHelper extends SQLiteOpenHelper {
public static SQLiteDatabase db;
static final String DATABASE_NAME = "User.db";
static final int DATABASE_VERSION = 1;
public static final String KEY_ID="ID";
public static final String KEY_fname="firstName";
public static final String KEY_lname="lastName";
public static final String KEY_pass="password";
public static final String KEY_email="email";
public static final String KEY_phone="phone";
public static final String KEY_add="add";
public static final String Table_User="Reg_User";
public dbHelper(Context context)
{
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase _db)
{
_db.execSQL("CREATE TABLE"+ Table_User+ "("+ KEY_ID+" integer primary key autoincrement,"+
KEY_fname+" text,"+KEY_lname +" text,"+KEY_pass+" text,"+ KEY_email+" text,"+ KEY_phone+" text,"+KEY_add+"text)");
}
@Override
public void onUpgrade(SQLiteDatabase _db, int _oldVersion, int _newVersion)
{
_db.execSQL("DROP TABLE IF EXISTS " +Table_User);
onCreate(_db);
}
public void insert(String firstName, String lastName, String password, String email, String phone, String add)
{
SQLiteDatabase db=this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(KEY_fname, firstName);
values.put(KEY_lname, lastName);
values.put(KEY_pass,password);
values.put(KEY_email,email);
values.put(KEY_phone,phone);
values.put(KEY_add, add);
db.insert(Table_User, null, values);
db.close();
}
public static String getSingleEntry(String email)
{
Cursor cursor=db.query("Reg_User", null, " KEY_email=?", new String[]{email}, null, null, null, null);
if(cursor.getCount()<1)
{
cursor.close();
return "NOT EXIST";
}
cursor.moveToFirst();
String password= cursor.getString(cursor.getColumnIndex("KEY_pwd"));
cursor.close();
return password;
}
}
我无法弄清楚哪里是在这段代码的问题。
我不确定，但我认为它不起作用，因为“ add”本身就是一条SQL语句。（http://www.1keydata.com/sql/alter-table-add-column.html）。
你可以在你的代码段看到“添加”得到了彰显每次
