intent传递数据方法总结

传递正常数据：
1：intent 传递：
Intent intent = new Intent(context, HomeDetailActivity.class);
intent.putExtra(“url”,newest.url);
Log.e(“jxf”,”home页列表点击位置url”+newest.url);
context.startActivity(intent);
getActivity().overridePendingTransition(R.anim.push_left_in, R.anim.push_left_out);

获取：Intent intent=getIntent();url=intent.getStringExtra("url");

2：intent 封装bundle：bundle传递数据

Intent intent=new Intent(context, ChannelActivity2.class);Bundle bundle = new Bundle();bundle.putInt("teacherId", contents.get(position - 1).teacherId);bundle.putString("portraitUrlSmall", contents.get(position - 1).portraitUrlSmall);bundle.putString("portraitUrlBig", contents.get(position - 1).portraitUrlBig);bundle.putString("nickname", contents.get(position - 1).nickname);bundle.putString("catgoryName", contents.get(position - 1).catgoryName);bundle.putString("catgoryId", contents.get(position-1).catgoryId);bundle.putInt("catgoryIdMark", catgoryId);intent.putExtras(bundle);context.startActivity(intent);getActivity().overridePendingTransition(R.anim.push_left_in, R.anim.push_left_out);获取：Bundle bundle=getIntent().getExtras();teacherId=bundle.getInt("teacherId");portraitUrlSmall=bundle.getString("portraitUrlSmall");portraitUrlBig=bundle.getString("portraitUrlBig");nickname=bundle.getString("nickname");catgoryNames=bundle.getString("catgoryName");catgoryIds=bundle.getString("catgoryId");catgoryIdMark= bundle.getInt("catgoryIdMark");

3：intent传递序列化对象集合
Intent intent=new Intent(SubscriptionActivity.this,PlayActivity.class);
intent.putExtra(“list”, (Serializable) lessons);

获取：lessons= (ArrayList<MusicLesson>) getIntent().getSerializableExtra("list");

4：intent传递序列化对象集合和其他数据
Intent intent=new Intent(SubscriptionActivity.this,PlayActivity.class);
Bundle bundle=new Bundle();
bundle.putString(“portraitUrlSmall”, portraitUrlSmall);
bundle.putString(“nickname”, nickname);
bundle.putInt(“itemposition”, position);
intent.putExtras(bundle);
intent.putExtra(“list”, (Serializable) lessons);
startActivityForResult(intent, 500);
overridePendingTransition(R.anim.push_left_in, R.anim.push_left_out);

获取：Bundle bundle = getIntent().getExtras();portraitUrlSmall=bundle.getString("portraitUrlSmall");nickname=bundle.getString("nickname");itemposition=bundle.getInt("itemposition");lessons= (ArrayList<MusicLesson>) getIntent().getSerializableExtra("list");title=lessons.get(itemposition).title;categoryName=lessons.get(itemposition).categoryName;pictureUrlSmall=lessons.get(itemposition).pictureUrlSmall;url=lessons.get(itemposition).url;initCurrentposition=lessons.get(itemposition).currentposition;

5：intent封装bundle传递序列化对象
Intent intent = new Intent(context, DetailofHistoryTicketActivity.class);
TicketInfoBean ticketInfoBean = ticketInfoBeans.get(position-1);
Log.e(“jxf”,”打印传递的字符串对象ordersTicketDetailProtocolList+++++++”+ticketInfoBean.ordersTicketDetailProtocolList);
Bundle bundle=new Bundle();
bundle.putSerializable(“ticketInfoBean”, ticketInfoBean);
intent.putExtras(bundle);
context.startActivity(intent);
getActivity().overridePendingTransition(R.anim.push_left_in, R.anim.push_left_out);

获取：TicketInfoBean ticketInfoBean= (TicketInfoBean) getIntent().getSerializableExtra("ticketInfoBean");序列化的传递：值是传递对象的一份copy：并不是和上页传递过来的对象是同一对象：比如：改变对象，另一页的并不会发生改变。
