Answer 1

发送HashMap

HashMap<String, Object> hashmapobject =new HashMap<>();
HashMap<String, Object> newhashMap=new HashMap<>();
hashmapobject.put("key",newhashMap);

Intent intent = new Intent(SenderActivity.this, NextActivity.class);
intent.putExtra("hashMapKey", hashmapobject);
startActivity(intent);

接收HashMap

Intent intent = getIntent();    
HashMap<String, Object> hashMapObject = (HashMap<String, Object>)       intent.getSerializableExtra("hashMapKey");
HashMap<String, Object> newhashMap=(HashMap<String, Object>)hashMapObject.get("key");
