Question

我希望在登录期间将以下jsonArray存储在会话中，并在以后需要时在另一个活动中逐个访问这些元素。我完全糊涂了。登录成功后，我收到以下数据。我该怎么做？这是我的登录页面

public class Login extends AppCompatActivity {
String mobile, password;
TextView forgot_password;
EditText mobile_num,pass;
Button log_btn;
AlertDialog.Builder builder;
private Session session;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);
    Login.this.setTitle("Vendor Screen");
    builder = new AlertDialog.Builder(Login.this);
    forgot_password = findViewById(R.id.forgot_pwd);
    log_btn = findViewById(R.id.login_btn);
    mobile_num = findViewById(R.id.mobile);
    pass = findViewById(R.id.password);
    forgot_password.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent i = new Intent(Login.this,Forgot_password.class);
            startActivity(i);
        }
    });

    //Login Page
    log_btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            ConnectivityManager ConnectionManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo networkInfo = ConnectionManager.getActiveNetworkInfo();
            if (networkInfo != null && networkInfo.isConnected() == true) {
                mobile = mobile_num.getText().toString();
                password = pass.getText().toString();
                String url = "https://vendorapp.web4rest.com/vendorController/auth?username=" + mobile + "&password=" + password;

Answer 1

您可以遵循以下基本想法：

if (Integer.parseInt(jobject.getString("status")) == 200 {
    ...
    SharedPreferences preferences = 
        PreferenceManager.getDefaultSharedPreferences(this);
    SharedPreferences.Editor editor = preferences.edit();

    var userData = jobject.getObject("userdata");
    editor.putInt("ID", userData.getInt("ID"));
    editor.putString("FIRM_NAME", userData.getString("FIRM_NAME"));
    // etc...
    editor.commit();
    ...
}

然后在你的其他活动中：

SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
var id = preferences.getInt("ID", -1);
var firmName = preferences.getString("FIRM_NAME", null);

如果未找到偏好设置，则上面的-1和null将是给定的值。
