你可以试试这个：

要在启动新活动时将信息从一项活动传递到另一项活动，请执行以下操作：

Intent top = new Intent(Main.this, New.class);
Bundle b = new Bundle();
b.putString("key1", "value1");
b.putString("key2", "value2");
b.putString("key3", "value3");
top.putExtras(b);
startActivity(top);

然后在新启动的活动中，在 onCreate() 中输入以下内容：

Bundle b = getIntent().getExtras();
String one = b.get("key1");
String two =b.get("key2");
String three =b.get("key3");

这将使用您提供的密钥从上一个活动中获取值。

好吧，你说你知道如何通过意图传递捆绑包，为什么不在你的类中创建一个用当前日期初始化的变量。

variable value = current date;

onClick 任何按钮，您将变量值更改为要发送到活动的值

onClick(){
value = value you want to send
}

并将该参数捆绑发送到意图。

因此您的要求：

 " if user not click any value then go current date value as parameter else what ever button eser click that day value will go as parameter"

将起作用，如果未单击任何内容，则变量value已使用当前日期初始化，因此将发送到活动，您可以按照您想要的方式处理它。

请忽略语法，它的 jst 伪代码。

在开头使用 afunction和一个变量dtSelect 集，如果用户选择任何按钮，则将该特定值设置为 dtSelectdtSelect = default

一旦您存储了一个值，dtSelect将其传递给function(as i.putstring()) 以根据您在变量中的值执行您想要的任务...
