我已经得到了一些自定义对象，如 RootObject 和表格我要传递到下一个活动。

这是一个例子 RootObject ：

 公共类RootObject
{
    公共表格表格{获得;组; }
}
 

但我怎么能传递 RootObject 与下一个活动的意图并获得在未来活动？在表格中，仍然有多个属性与列表之类的东西，我需要访问一些属性在我的下活动。我的意图被称为是这样的：

  saveButton.Click + =委托{
    如果（ValidateScreen（））{
        保存数据（）;
        意向意图=新的意图（此的typeof（MainActivity））;
        叠B =新包（）;
        b.PutSerializable（RootObject，RootObject）;
        StartActivity（意向）;
    }
};
 

解决方案

这是你如何去做。你的类需要实现Serializable或Parcelable。 在第一个活动（如你想从发送）：

 最终意向意图=新的意图（这一点，SecondActivity.class）;
intent.putExtra（my_class，your_object）;
startActivity（意向）;
 

然后在你的第二个活动，你会怎么做：

 最终意图passedIntent = getIntent（）;
最终YourClass my_class =（YourClass）passedIntent.getSerializableExtra（my_class）;
 

也有这样做，使用捆绑::另一种方式

从你的类一样创建一个软件包：

 公开捆绑toBundle（）{
    叠B =新包（）;
    b.putString（SomeKey，someValue中）;

    返回b;
}
 

然后通过该软件包意图。现在，你可以通过像束重建你的类的对象

 公共CustomClass（上下文_context，叠B）{
    上下文= _context;
    classMember = b.getString（SomeKey）;
}
 

I've got a few custom objects like RootObject and Form that I want to pass on to the next activity.

This is an example of RootObject:

public class RootObject
{
    public Form Form { get; set; }
}

But how can I pass RootObject to the next activity with an Intent and get it in the next Activity? In Form there are again multiple properties with Lists and stuff and I need to access some of the properties in my next Activity. My intent is called like this:

saveButton.Click += delegate {
    if(ValidateScreen()){
        SaveData();
        Intent intent = new Intent(this, typeof(MainActivity));
        Bundle b = new Bundle();
        b.PutSerializable("RootObject", RootObject);
        StartActivity(intent);
    }
};

This is how you can go about it. Your class needs to implement Serializable or Parcelable. In the first Activity(where you want to send from):

final Intent intent = new Intent(this, SecondActivity.class);
intent.putExtra("my_class", your_object);
startActivity(intent);

Then in your second Activity, you would do:

final Intent passedIntent = getIntent();
final YourClass my_class = (YourClass) passedIntent.getSerializableExtra("my_class");

There is also another way of doing it, using Bundles::

Create a Bundle from your class like:

public Bundle toBundle() {
    Bundle b = new Bundle();
    b.putString("SomeKey", "SomeValue");

    return b;
}

Then pass this bundle with INTENT. Now you can recreate your class object by passing bundle like

public CustomClass(Context _context, Bundle b) {
    context = _context;
    classMember = b.getString("SomeKey");
}
