Как использовать нестатический способ "getSystemService" в пользовательском адаптере?

Question

В затмении Android, когда я хочу использовать нестатический метод "getSystemService", он показывает ошибку:

Невозможно создать статическую ссылку на нестатический метод getContext() из типа ArrayAdapter.

ArrayAddapter.java:

package ir.redreactor.app.Com.NovinEr;

import java.util.ArrayList;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;


public class AdapterNote extends ArrayAdapter<StructNote> {

public AdapterNote(ArrayList<StructNote> array) {
    super(G.context, R.layout.adapter_notes, array);
}


private static class ViewHolder {

    public ViewGroup LayoutRt;
    public TextView  txtTitle;
    public TextView  txtSort;
    public TextView  txtTableName;
    public TextView  txtID;
    public TextView  txtpos;
    public TextView  txtDetail;


    public ViewHolder(View view) {
        txtTitle = (TextView) view.findViewById(R.id.txtTitleAN);
        txtSort = (TextView) view.findViewById(R.id.txtSortAN);
        txtTableName = (TextView) view.findViewById(R.id.txtTableNameAN);
        txtID = (TextView) view.findViewById(R.id.txtIDAN);
        txtpos = (TextView) view.findViewById(R.id.txtpos);
        txtDetail = (TextView) view.findViewById(R.id.txtDetailAN);
        LayoutRt = (ViewGroup) view.findViewById(R.id.layout_Rt);
    }


    private void copy(String strdata) {
        android.text.ClipboardManager clipboard = (android.text.ClipboardManager) getContext().getSystemService(Context.CLIPBOARD_SERVICE);
        clipboard.setText(strdata);
    }


    public void fill(ArrayAdapter<StructNote> Adapter, StructNote Item, final int position) {
        txtTitle.setText(Item.title);
        txtDetail.setText(Item.detail);
        txtSort.setText(Item.Sort.toString());
        txtTableName.setText(Item.nameOfTable);
        txtID.setText(Item.intID.toString());
        txtpos.setText("" + position);
        LayoutRt.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                copy(txtTitle.getText().toString() + "\n" + txtDetail.getText().toString());
            }
        });
    }
}


@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    StructNote item = getItem(position);
    final ViewHolder holder;
    if (convertView == null) {
        convertView = G.inflater.inflate(R.layout.adapter_notes, parent, false);
        holder = new ViewHolder(convertView);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }
    holder.fill(this, item, position);
    return convertView;
}

}

StructNote.java:

package ir.redreactor.app.Com.NovinEr;

import android.app.Activity;
import android.content.Context;


public class StructNote {

public String  nameOfTable;
public Integer Sort;
public Integer intID;
public Boolean Favorite;
public String  title;
public String  detail;

}

G.java является классом Global Class

public class G extends Application {

    // Creating Context
    public static Context               context;
    // Creating Log
    public static String                LOG_TAG         = "RR1";
    public static String                LOG_ERR         = "NVR";
    //Creating Current Activity Finder 
    public static Activity              currentActivity;

    @Override
    public void onCreate() {
        super.onCreate();
        context = this.getApplicationContext();
    }
}

Когда я использую "getSystemService" без "getContext()", он показывает мне ошибку ниже: метод getSystemService(String) не определен для типа AdapterNote.ViewHolder

спасибо, Рагхунандан, так что AdapterNote.java будет:

package ir.redreactor.app.Com.NovinEr;

import java.util.ArrayList;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;


public class AdapterNote extends ArrayAdapter<StructNote> {

public LayoutInflater mInflater;
public static Context context;


public AdapterNote(ArrayList<StructNote> array, Context context) {
    super(context, R.layout.adapter_notes, array);
    mInflater = LayoutInflater.from(context);
    this.context = context;
}


private static class ViewHolder {

    public ViewGroup LayoutRt;
    public TextView  txtTitle;
    public TextView  txtSort;
    public TextView  txtTableName;
    public TextView  txtID;
    public TextView  txtpos;
    public TextView  txtDetail;


    public ViewHolder(View view) {
        txtTitle = (TextView) view.findViewById(R.id.txtTitleAN);
        txtSort = (TextView) view.findViewById(R.id.txtSortAN);
        txtTableName = (TextView) view.findViewById(R.id.txtTableNameAN);
        txtID = (TextView) view.findViewById(R.id.txtIDAN);
        txtpos = (TextView) view.findViewById(R.id.txtpos);
        txtDetail = (TextView) view.findViewById(R.id.txtDetailAN);
        LayoutRt = (ViewGroup) view.findViewById(R.id.layout_Rt);
    }


    private void copy(String strdata) {
        android.text.ClipboardManager clipboard = (android.text.ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
        clipboard.setText(strdata);
    }


    public void fill(ArrayAdapter<StructNote> Adapter, StructNote Item, final int position) {
        txtTitle.setText(Item.title);
        txtDetail.setText(Item.detail);
        txtSort.setText(Item.Sort.toString());
        txtTableName.setText(Item.nameOfTable);
        txtID.setText(Item.intID.toString());
        txtpos.setText("" + position);
        LayoutRt.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                copy(txtTitle.getText().toString() + "\n" + txtDetail.getText().toString());
            }
        });
    }
}


@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    StructNote item = getItem(position);
    final ViewHolder holder;
    if (convertView == null) {
        convertView = mInflater.inflate(R.layout.adapter_notes, parent, false);
        holder = new ViewHolder(convertView);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }
    holder.fill(this, item, position);
    return convertView;
  }
}

Передайте контекст конструктору адаптера

new AdapterNote(ArrayList<StructNote> array,ActivityName.this)

затем

LayoutInfalter mInflater; 
Context context;
public AdapterNote(ArrayList<StructNote> array,Context context) {
super(context, R.layout.adapter_notes, array);
mInfalter = LayoutInfalter.from(context);
this.context =context;
} 

затем

 convertView = mInflater.inflate(R.layout.adapter_notes, parent, false);

затем

 android.text.ClipboardManager clipboard = (android.text.ClipboardManager)context.getSystemService(Context.CLIPBOARD_SERVICE);
