このエラーは私を怒らせています
これは、パラメーターを渡すコードです。
Intent intent = new Intent(this, TheClass.class);
Bundle bundle = new Bundle();
bundle.putInt("int_value",1);
bundle.putParcelableArrayList("USER_ARR",arr);
intent.putExtras(bundle);
startActivity(intent);
arr は ArrayList で、 User は parcellable です
反対側は次のとおりです。
Bundle bundle = this.getIntent().getExtras();
ArrayList<User> users = bundle.getParcelableArrayList("USER_ARR");
int int_value = bundle.getInt("int_value");
私もこのリンクに従ってみました:
