Android DialogFragmentで引数を扱う

Last updated at Posted at 2016-09-27

ダイアログを呼び出す側で、引数を渡すところ

HogeFragment.java
// 〜省略
dialogFragment = new AlertDialogFragment();
Bundle args = new Bundle();
args.putInt("hoge_arg1",position); //引数
dialogFragment.setArguments(args);
dialogFragment.show(getActivity().getFragmentManager(),"dialog");
// 〜省略

ダイアログ表示に渡しした引数を取得するところ

AlertDialogFragment.java
// 〜省略
// アラートダイアログ
public static class AlertDialogFragment extends DialogFragment {
        
    private AlertDialog.Builder alert;

    @Override
	public Dialog onCreateDialog(Bundle savedInstanceState) {
		alert = new AlertDialog.Builder(getActivity());
		int hogeInt = getArguments().getInt("hoge_arg1");
// 〜省略
