複数選択肢のAndroid Spinnerの使い方ナビゲーションの引き出し引き出しアクティビティ

Question

複数のアイテム、つまりチェックボックス付きのスピンナを選択できるスピナーを作成するにはどうすればよいですか？同時に、私はナビゲーション・ドロワ・アクティビティの断片の中でこの複数の選択肢のスピナを使用する必要があります。

誰かが適切なサンプルコードを使用して疑いを明確にすることができます。

ありがとうございます！私は、私たちに複数の選択肢のスピナーをspinner2を変更する必要が

public class Doctor extends Fragment { public Doctor() { // Required empty public constructor }

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 
    getActivity().setTitle("Doctor"); 
    View v = inflater.inflate(R.layout.fragment_doctor, container, false); 
    String [] values = 
      {"All Town","Paris","Kodambakkam","Nungambakkam","T.Nagar","Egmore"}; 
    Spinner spinner = (Spinner) v.findViewById(R.id.town); 
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_spinner_item, values); 
    adapter.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line); 
    spinner.setAdapter(adapter); 

    String [] values1 = 
      {"Select Doctor","Doctor1","Doctor2","Doctor3","Doctor4"}; 
    Spinner spinner1 = (Spinner) v.findViewById(R.id.doctor); 
    ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_spinner_item, values1); 
    adapter.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line); 
    spinner1.setAdapter(adapter1); 

    String [] values2 = 
      {"Worked With","Nagaraj","Muthuvel"}; 
    Spinner spinner2 = (Spinner) v.findViewById(R.id.doctor); 
    ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_spinner_item, values2); 
    adapter.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line); 
    spinner2.setAdapter(adapter2); 

    return v; 
} 
public void onViewCreated(View view,@Nullable Bundle savedInstanceState){ 
    super.onViewCreated(view, savedInstanceState); 

} 

}

。私はFragmentからクラスを拡張しています。したがって、この複数の選択肢スピナー

Answer 1

How do I create spinner which allows to choose multiple items, i.e spinner with check boxes? 

を処理する方法がわからないmultiselectionspinnerを使用してみてください。 https://stackoverflow.com/a/6022474/6616489

とナビゲーション引き出しのフラグメント内部

複数選択スピナーのため

は、上記のコードhttps://stackoverflow.com/a/20017862/6616489

Answer 2

public class Doctor extends Fragment{ 

MultiSelectionSpinner spinner2; 
FragmentManager fm = getFragmentManager(); 
public Doctor() { 
    // Required empty public constructor 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 
    getActivity().setTitle("Doctor"); 
    View v = inflater.inflate(R.layout.fragment_doctor, container, false); 

    String [] values = 
      {"All Town","Paris","Kodambakkam","Nungambakkam","T.Nagar","Egmore"}; 
    Spinner spinner = (Spinner) v.findViewById(R.id.town); 
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_spinner_item, values); 
    adapter.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line); 
    spinner.setAdapter(adapter); 

    String [] values1 = 
      {"Select Doctor","Doctor1","Doctor2","Doctor3","Doctor4"}; 
    Spinner spinner1 = (Spinner) v.findViewById(R.id.se_doctor); 
    ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_spinner_item, values1); 
    adapter1.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line); 
    spinner1.setAdapter(adapter1); 

    String [] values2 = 
      {"Worked With","Nagaraj","Muthuvel"}; 
    // Multi spinner 
    spinner2 = (MultiSelectionSpinner)v.findViewById(R.id.work); 
    spinner2.setItems(values2);return v; 
}} 

を参照してくださいは、複数の選択肢のスピナーを保持している（注：Spinner2）

上記のコードは、spinner2から呼び出されているMulti Selection Spinnerを作成するためのコードです。
