putExtra putExtras 小结

存 intent.putExtra("age", 21); 

取 int age = intent.getIntExtra("age",-1);
// -1为默认值 取不到就赋值-1

存 bundle.putParcelable("Create
key", t);

   intent.putExtras(bundle);

取   一 Parcelable parcelable=intent.getParcelableExtra("Create key");

   二 Parcelable parcelable=intent.getExtras().getParcelable("Create key");
