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.
