//传递对象
Bundle bundle = new Bundle();
intent = new Intent(getApplicationContext(), YourActivity.class);
bundle.putSerializable("youJavaBean", youJavaBean);

startActivity(intent); //接收对象
Intent intent = getIntent();
Bundle bundle=intent.getExtras(); //接收对象
youJavaBean= (YouJavaBean)bundle.get("youJavaBean");
