フラグメントで2回目のダイアログを膨張させる際にエラーが発生しました

Question

私はこのライブラリを使用しました：https://github.com/kristiyanP/colorpicker私のアプリにカラーピッカーを持たせるには、実装した後に複数回使用できません。私は、カラーピッカーを開こう：私はここに投稿する前に検索が、どのような方法でこのエラーを修正couldntの

CODE。 ありがとうございます。

Answer 1

show()を複数回（クリックごとに）呼び出すことは可能ですか？また、カラーピッカーはそれをサポートしていない可能性がありますか？

これが問題であれば、クリックごとに新しいColorPickerを作成すると宣言できます。例：

@Nullable 
@Override 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
    View RootView = inflater.inflate(R.layout.fragment_addcategory, container, false); 

    db = new SQLiteHandler(getApplicationContext()); 
    categoriesspinner = (Spinner) RootView.findViewById(R.id.spinnercategory); 

    Button color = (Button) RootView.findViewById(R.id.color); 
    color.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View v) { 
      colorPicker = new ColorPicker(getActivity()); 
      colorPicker.show(); 
     } 
    }); 

    return RootView; 
} 

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

    getActivity().setTitle("Adicionar categoria"); 

    if (colorPicker != null) { 
     colorPicker.setOnChooseColorListener(new ColorPicker.OnChooseColorListener() { 
      @Override 
      public void onChooseColor(int position, int color) { 
       Log.d("color:", String.valueOf(color)); 
       Log.d("color:", String.valueOf(position)); 
      } 

      @Override 
      public void onCancel() { 
      } 
     }); 
    } 

    loadCategoriesSpinner(); 
}
