Android 如何在两个活动之间同步复选框状态？

我有两个活动，都有相似的布局，即复选框。我想同步两个活动中复选框的状态。我该怎么做

设置类

为什么不将一个

布尔值作为
intent.putExtra（“checkValue”，value）传递

具体来说：

在活动A中

让我们假设
ActivityA扩展了Activity

private boolean checkState = true; //Let's say you checkbox is currently checked.

public void sendCheckState(){
    Intent intent = new Intent(ActivityA.class, ActivityB.class);
    intent.putExtra("checkValue", value);
    startActivity(intent);
}

Intent intent = getIntent();

Bundle extras = intent.getExtras();
if (extras != null) {

    if (extras.containsKey("checkValue")) {
        boolean checkValue = extras.getBoolean("checkValue", false);

        // TODO: Do something with the value.
    }
}

现在，您只需在获得
布尔值后调用
sendCheckState（）

在活动B中

您可以在
onCreate（）
中调用此代码（我们仍然假设您的
ActivityB扩展了活动
）

您可以为此使用
SharedReferences
。在每个
活动的
OnCreate（）
方法中。您可以检查
SharedReferences
的值是否执行。如果执行，则根据它设置
复选框的状态。
您可以在
复选框上设置
SharedReference
值
事件侦听器
OnCheckedChangeListener（）
这是两个活动之间的通信问题。为此，您可以尝试以下方法：

正如Jatin Dudhat所说，您可以从活动A保存数据，从活动B获取数据
使用startActivity（Intent），如果要将数据从活动A传递到B，可以在活动A中使用startActivity（Intent），并将Intent与数据一起使用并传递到活动B
如果您在活动A中启动活动B，并且希望在返回到活动A时从活动B获取一些数据，则可以使用startActivityForResult（intent，requestCode）
您还可以使用广播进行两个活动之间的通信
可以通过类扩展应用程序的成员变量保存数据
不太准确，但希望能为您提供一些帮助。
将签出状态从活动A传递到活动Bextras@Libin我该怎么做？请解释清楚。谢谢检查我的答案。我按照@Libin的建议做了。去学习android的基础知识，比如intent、SharedReference等。你能发布你的代码吗？我也许能帮你，但我需要先做点什么。假设您的
复选框所在的
活动是
活动a
。现在，如果您看到我的答案，您可能会看到，我假设一个
布尔值
，其中一个值为
复选框
es状态（在我的示例中：
true
）。然后，如果您的
活动a扩展了活动
，您可以使用
开始活动（intent）在该
活动的任何部分a
。所以，您不应该无法实现
意图。
在这种情况下，您打算在哪里实现它？我再次编辑了我的答案。我尽可能的具体。你已经选择了@Jatin Dudhat suggestion。看看答案。但是，在您的代码中，您正在实现
SharedReferences
。请检查链接。
