我有对象的数组列表,我用这个例子来获得此ArrayList从一个活动到另一个活动: http://androidideasblog.blogspot.in/2010/02/passing-list-of-objects-between.html
这里是我的代码的一部分:
活动1:
Intent myIntent = new Intent(context, JournalArticles.class);
Bundle b = new Bundle();
b.putParcelableArrayList("articles", articles);
myIntent.putExtras(b);
startActivityForResult(myIntent,0);
活动2:
Bundle b = this.getIntent().getExtras();
ArrayList<Article> articles = b.getParcelableArrayList("articles");
但在这里,我得到一个错误,这里是日志:
