Android - 如何在活动之间传递HashMap <String,String>？

Question

如何将detailHashMap 传递给另一个Activity？

HashMap<String,String> detail = new HashMap<String, String>();
detail.add("name","paresh");
detail.add("surname","mayani");
detail.add("phone","99999");
......
......

Answer 1

这很简单,所有Collections对象都实现Serializable(sp？)interface,这意味着它们可以作为Extras传递Intent

使用putExtra(String key, Serializable obj)插入HashMap和其他Activity用途getIntent().getSerializableExtra(String key),您需要将返回值转换为一个HashMap虽然.

Answer 2

解:

发件人活动:

HashMap<String, String> hashMap= adapter.getItem(position);
Intent intent = new Intent(SourceActivity.this, DestinationActivity.class);
intent.putExtra("hashMap", hashMap);
startActivity(intent);

接收者活动:

Intent intent = getIntent();    
HashMap<String, String> hashMap = (HashMap<String, String>) intent.getSerializableExtra("hashMap");
