java - 在提交时传递自定义对象

Question

我正在开发 Android 应用程序。我主要从事Spring工作，所以对android开发不太了解，所以我安装了android注解和Spring Rest模板来连接服务器发送数据。目前我正在尝试做的事情是填写 Android 应用程序中的一些文本字段，这些变量在一个 Java 文件中提到。然后，单击按钮时，我想将该对象传递给其中一个方法，在其中我可以与服务器建立 REST 连接以发送数据。请看一下代码，然后告诉我:

我的 Activity :

public class MyActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    // At button push, this method is called, I checked that, but I would like to receive an Object of class mentioned below. 
    public void sendMessage(View view){
        Log.d(view.toString(),"We reached sendMessage");
    }
}

餐厅等级:

public class Restaurant {

    private int id;

    private String username;

    private String password;

    private String firstName;
//Getters and setters ommitted
}

布局文件main.xml:

</LinearLayout>
</ScrollView>

如果有人有用户 Spring-rest-template 和 Android 注释，那么详细的教程和小示例也会非常有帮助。多谢。

您可以尝试以下代码:

public class MyActivity extends Activity {
    EditText editText = (EditText) findViewById(R.Id.restaurantName); 

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    // At button push, this method is called, I checked that, but I would like to receive an Object of class mentioned below. 
    public void sendMessage(View view){
        Log.d(view.toString(),editText.getText().toString());
    }
}
