如何在不扩大活动的一类使用getIntent（）？ [英] How to use getIntent() in a class that does not extend Activity?

问题描述

我试图通过从一个类玩它通过使用扩展活动的字符串：

I am trying to pass a String from a class "Play" which extends Activity by using:

Bundle data = new Bundle();
Intent i = new Intent(Play.this, Receive.class);
String category;

data.putString("key", category);
i.putExtras(data);

于是，接收类，它是一种非活性类不会扩展活动将从播放接收字符串。

Then, the "Receive" class which is a non Activity class and does not extend Activity will receive the String from "Play".

但是，当我尝试使用这个code接收数据：

But when I try to receive the data using this code:

Bundle receive = new Bundle();
String passed;

receive = getIntent().getExtras();
passed = receive.getString("key");

我的单词getIntent（）得到一个错误，并建议我创造一个方法getIntent（）。

I get an error on the word "getIntent()" and suggests me to create a method getIntent().

什么是可能的解决这个问题？
谢谢！

What is the possible solution to this problem? THANKS!

推荐答案

意图不是这里所必要的。你可以做这样的事情：

Intent is not nessesary here. You can just do something like this:

Play.class：

Play.class :

public String getCategory() {
    return category;
}

和在Receiver.class：

and in Receiver.class :

Play playObject = new Play();
passed = playObject.getCategory();

或者你也可以使用静态字段作为PKS提及，但它并不总是一个很好的模式。

Or you can use static field as pKs mentioned but it's not always a good pattern.
