Question

我正在尝试制作日常计划的应用程序，我每天都会使用片段。他们每个人都有CustomAdapter，而且重复性太强。我尝试了一切，但我找不到从不同阶层使用它的方法。

public class Day1Fragment extends Fragment {

final String FILE_NAME="day1fragment.txt";
FileOutputStream fos=null;

private ArrayList<String> exerciseName=new ArrayList<String>();
private ArrayList<String> exerciseDesc=new ArrayList<String>();
private ArrayList<Integer> exerciseSet=new ArrayList<Integer>();
private ArrayList<Integer> exerciseRepeat=new ArrayList<Integer>();

CustomAdapter customAdapter=new CustomAdapter();
ListView day1List;
ImageButton addButton;
Dialog addDialog,fitnessDialog;


public static Day1Fragment newInstance() {
    return new Day1Fragment();
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@Override
public void onViewCreated(final View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    addDialog=new Dialog(view.getContext());
    fitnessDialog=new Dialog(view.getContext());
    day1List=(ListView)view.findViewById(R.id.day1list);
    addButton=(ImageButton)view.findViewById(R.id.addButton);
    FitnessClass.fragmentInit(view,day1List,customAdapter,addButton,addDialog,fitnessDialog,exerciseName,exerciseDesc,exerciseSet,exerciseRepeat,FILE_NAME,this.getContext(),fos);
}

//TODO CHANGE LISTS
class CustomAdapter extends BaseAdapter{

    @Override
    public int getCount() {
        return exerciseName.size();
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(final int position,View convertView, ViewGroup parent) {
        convertView=getLayoutInflater().inflate(R.layout.fitness_layout,null);
        TextView exerciseNameText=(TextView)convertView.findViewById(R.id.exerciseLayoutText);
        TextView setsText=(TextView)convertView.findViewById(R.id.setsText);
        TextView repeatsText=(TextView)convertView.findViewById(R.id.repeatsText);

        exerciseNameText.setText(exerciseName.get(position));
        setsText.setText(exerciseSet.get(position).toString());
        repeatsText.setText(exerciseRepeat.get(position).toString());
        return convertView;
    }
}

那么我如何使用来自不同类的CustomAdapter类呢？当我试图在不同的类中使用它时，我在这部分中遇到错误：

convertView=getLayoutInflater().inflate(R.layout.fitness_layout,null);

您可以在程序包中创建名为Java Class的新CustomAdapter，并将CustomAdapter代码放在那里而不是Day1Fragment.java内。这样，您就可以在任何地方拨打CustomAdapter，Day1Fragment.java看起来更干净，代码更少。

我如何使用不同类的BaseAdapter？
