با استفاده از کد زیر میتونید این کار رو انجام بدید

 Delete.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View arg0) {
                    AlertDialog.Builder builder = new AlertDialog.Builder(G.currentActivity);
                    builder.setTitle("حذف").setMessage("حذف شود؟");
                    builder.setPositiveButton("بله", new DialogInterface.OnClickListener() {

                        @Override
                        public void onClick(DialogInterface arg0, int arg1) {


                            G.database.execSQL("DELETE FROM person WHERE person_name='" + customername + "'");
                            adapter.remove(item);
                            Toast.makeText(G.currentActivity, "حذف شد", 2000).show();
                        }
                    });
                    builder.setNegativeButton("خیر", null);

                    builder.setIcon(android.R.drawable.ic_dialog_alert).show();
                }
            });

ای کد من هست

 


public class AdapterData extends ArrayAdapter<StructData> {

    public AdapterData(ArrayList<StructData> array) {
        super(G.context, R.layout.date_list_layout, array);
    }


    private static class ViewHolder {

        public ViewGroup layoutRoot;
        public TextView  txt1;
        public TextView  txt2;
        public TextView  txt3;
		public ImageView img1;
		public ImageView img2;
        


        public ViewHolder(View view) {
        	txt1 = (TextView) view.findViewById(R.id.txt1);
        	txt2 = (TextView) view.findViewById(R.id.txt2);
            txt3 = (TextView) view.findViewById(R.id.txt3);
            layoutRoot=(ViewGroup) view.findViewById(R.id.lay_list_item);
            img1=(ImageView) view.findViewById(R.id.img1);
			img2=(ImageView) view.findViewById(R.id.img2);
        }


        public void fill(final ArrayAdapter<StructData> adapter, final StructData item, final int position) {
        	txt1.setText(item.txt1);
        	txt2.setText(item.txt2);
        	txt3.setText(item.txt3);
        	
        	if(item.img){
				img1.setVisibility(View.VISIBLE);
				img2.setVisibility(View.INVISIBLE);
			}else{
				img1.setVisibility(View.INVISIBLE);
				img2.setVisibility(View.VISIBLE);
			}
        	
        	if(!item.done){
        		layoutRoot.setBackgroundResource(R.drawable.list_item);
        	}else{
        		layoutRoot.setBackgroundResource(R.drawable.list_item2);
        	}
        	
        	layoutRoot.setOnClickListener(new OnClickListener() {
				
				@Override
				public void onClick(View arg0) {
					// TODO Auto-generated method stub
				
				final Dialog dialog=new Dialog(G.currentActivity);
				dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
				dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
				dialog.setContentView(R.layout.dialog_item);
				
				
				dialog.findViewById(R.id.layoutCloseDialog).setOnClickListener(new OnClickListener() {
					
					@Override
					public void onClick(View arg0) {
						// TODO Auto-generated method stub
						dialog.dismiss();
					}
				});
				dialog.findViewById(R.id.layoutDeleteDialog).setOnClickListener(new OnClickListener() {
					
					
					@Override
					public void onClick(View arg0) {
						// TODO Auto-generated method stub
						G.database.delete("gharz", "_id="+item._id, null);
						adapter.remove(item);
						adapter.notifyDataSetChanged();
						dialog.dismiss();
					}
				});
				dialog.findViewById(R.id.layoutbackColor).setOnClickListener(new OnClickListener() {
					
					@Override
					public void onClick(View arg0) {
						// TODO Auto-generated method stub
						G.database.execSQL("UPDATE gharz SET done='true' WHERE _id='"+item._id+"'");
                                                adapter.notifyDataSetChanged();
						dialog.dismiss();
					}
				});
				dialog.show();
					
				
					
					
				}
					
			});
            
           
        }
    }


    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;

        StructData item = getItem(position);
        if (convertView == null) {
            convertView = G.inflater.inflate(R.layout.date_list_layout, parent, false);
            holder = new ViewHolder(convertView);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        holder.fill(this, item, position);
        
        
        Animation anim =null;
        
        anim=AnimationUtils.loadAnimation(G.context, R.anim.push_left_in);
        convertView.startAnimation(anim);
        
        anim=null;
        return convertView;
    }
}

مشکل من الان این قسمت هست

 dialog.findViewById(R.id.layoutbackColor).setOnClickListener(new OnClickListener() {
					
					@Override
					public void onClick(View arg0) {
						// TODO Auto-generated method stub
						G.database.execSQL("UPDATE gharz SET done='true' WHERE _id='"+item._id+"'");
                                                adapter.notifyDataSetChanged();
						dialog.dismiss();
					}
				});

وقتی این قسمت اجرا میشه مقدار done برابر true میشه و قانونن باید رنگ بک گراند عوض بشه چون بالا این رو نوشتم اما این اتفاق نمی افتد مگر این که یک بار برنامه بسته و مجدد باز بشه
