Question

我有登录和重置密码活动。当我输入新的更新密码并尝试再次登录时，我无法使用新密码。使用旧密码登录可以正常工作。基本上，密码字段不会被更新/覆盖。

logcat中没有错误。只是密码没有更新。

请帮助我，因为我是Android开发的新手。

更新代码（DataRegister是具有GET和SET功能的类）：

public int updatePassword(DataRegister dataregister) {

db = dbHelper.getWritableDatabase();
ContentValues updated = new ContentValues();
updated.put("PASSWORD", dataregister.getPASSWORD());

return db.update(DataRegister.TABLE, updated, "EMAIL=?" , new String[]   {dataregister.getEMAIL()});

}

检索代码：

public String getPass(DataRegister dataRegister) {

db = dbHelper.getWritableDatabase();

Cursor cursor = db.query(DataRegister.TABLE, null, "EMAIL=?",
        new String[]{dataRegister.getEMAIL()}, null, null, null, null);
if (cursor != null && cursor.moveToFirst())

{
    pass = cursor.getString(cursor.getColumnIndex("PASSWORD"));
    cursor.close();
}
return pass;


// return contact


}

登录代码：

  String email = editTextUserName.getText().toString();
        dataRegister.setEMAIL(email);

        String password = editTextPassword.getText().toString();
        dataRegister.setPASSWORD(password);

        String storedPassword = loginDataBaseAdapter.getSinlgeEntry(dataRegister);

        Toast.makeText(Login.this, storedPassword,Toast.LENGTH_LONG).show();
        Boolean a=loginDataBaseAdapter.isExist(dataRegister.getEMAIL());
       validation = getSharedPreferences("myShaPreferences", Context.MODE_PRIVATE);

        if (password.equals(storedPassword)) {

            Toast.makeText(Login.this,
                    "Congrats: Login Successful", Toast.LENGTH_LONG)
                    .show();
        }

        else {

                Toast.makeText(Login.this,
                        "User Name or Password does not match",
                        Toast.LENGTH_LONG).show();


            }



    }
});

重置密码代码：

public class ResetPassword extends AppCompatActivity {


 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_reset_password);

 email = (EditText) findViewById(R.id.em2);
 dataRegister=new DataRegister();

loginDataBaseAdapter = new DatabaseAdapter(this);
loginDataBaseAdapter = loginDataBaseAdapter.open();



pass = (EditText) findViewById(R.id.text12);
conpass = (EditText) findViewById(R.id.text13);

email1 = email.getText().toString();
dataRegister.setEMAIL(email1);
pass1 = pass.getText().toString();

conpass1 = conpass.getText().toString();
dataRegister.setPASSWORD(conpass1);

Button btnReset = (Button) findViewById(R.id.btnReset);
btnReset.setOnClickListener(new View.OnClickListener() {
    public void onClick(View view) {


        if (pass1.equals(conpass1)) {

         loginDataBaseAdapter.updatePassword(email1,pass1);
            String newpass =loginDataBaseAdapter.getPass(dataRegister);

我没有足够的评论声誉，所以我会把我的建议写成答案......对不起

我认为这对你有帮助

在你的getPass方法

中

if (cursor != null)
cursor.moveToFirst()
    pass = cursor.getString(cursor.getColumnIndex("PASSWORD"));
    cursor.close();
