android用户上线下线问题

Question

public class LoginActivity extends BaseActivity {

private EditText accountEdit;

private EditText passwordEdit;

private Button login;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);
    accountEdit = findViewById(R.id.account);
    passwordEdit = findViewById(R.id.password);
    login = findViewById(R.id.login);

    login.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String account = accountEdit.getText().toString();
            String password = passwordEdit.getText().toString();
            if(account.equals("admin")&&password.equals("admin")){
                Intent intent = new Intent(LoginActivity.this,MainActivity.class);
                startActivity(intent);
                finish();
            }else{
                Toast.makeText(LoginActivity.this,"Account or password is invalid",Toast.LENGTH_SHORT).show();
            }
        }
    });

}

}

如图所示上线的时候，通过验证用户名和密码，然后跳转到另一个activity，那下线的时候应该清除什么信息

Answer 1

你这个。。并不需要清掉什么信息，你又没有保存登录信息
