推荐答案
您有几种选择:
1)使用包从的的://开发商.android.com /参考/安卓/内容/ Intent.html>意图:
1) Use the Bundle from the Intent:
Intent mIntent = new Intent(this, Example.class);
Bundle extras = mIntent.getExtras();
extras.putString(key, value);
2)创建一个新的捆绑
2) Create a new Bundle
Intent mIntent = new Intent(this, Example.class);
Bundle mBundle = new Bundle();
mBundle.putString(key, value);
mIntent.putExtras(mBundle);
3)使用<一个href="http://developer.android.com/reference/android/content/Intent.html#putExtra%28java.lang.String,%20java.lang.String%5b%5d%29">putExtra()该意向书的快捷方式
3) Use the putExtra() shortcut method of the Intent
Intent mIntent = new Intent(this, Example.class);
mIntent.putExtra(key, value);
然后,在启动的活动,您将通过阅读:
Then, in the launched Activity, you would read them via:
String value = getIntent().getExtras().getString(key)
注:捆绑有得与放的方法对所有的基本类型,parcelables的,和Serializables。我只是用字符串示范的目的。的
NOTE: Bundles have "get" and "put" methods for all the primitive types, Parcelables, and Serializables. I just used Strings for demonstrational purposes.
