android - How To Use non-staticHow “getSystemService” in Custom adapter? -

in android eclipse when want use non-statichow “getsystemservice", show me error:

cannot make static reference non-static method getcontext() type 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 global class class g.java:

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();     } } 

when use "getsystemservice" out "getcontext()" show me below error: method getsystemservice(string) undefined type adapternote.viewholder

thank raghunandan adapternote.java be:

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;   } } 

pass context adapter constructor

new adapternote(arraylist<structnote> array,activityname.this) 

then

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; }  

then

 convertview = minflater.inflate(r.layout.adapter_notes, parent, false); 

then

 android.text.clipboardmanager clipboard = (android.text.clipboardmanager)context.getsystemservice(context.clipboard_service);
