class MyAdapter extends BaseAdapter{

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

        @Override
        public Object getItem(int i) {
            //這個(gè)是返回當(dāng)前選擇條目?jī)?nèi)容

        @Override

        }
    }

優(yōu)化：1：ConvertView的復(fù)用
2：findViewById()的復(fù)用

1：ConvertView的復(fù)用

 if (view==null){
           //返回一個(gè)條目所對(duì)應(yīng)的View對(duì)象 (第三個(gè)參數(shù)為是否要掛在到父控件上 一般傳入null)
           view = View.inflate(Blackname_Activity.this, R.layout.listview_blackname, null);
}

2:findViewById()的復(fù)用
1:創(chuàng)建一個(gè)靜態(tài)的ViewHolder類(lèi)
里面創(chuàng)建你在ListView每個(gè)條目中想要找到的控件的名稱(chēng)

    static class ViewHolder{
        TextView tv_listView_blackname_phone;
        TextView tv_listView_blackname_mode;
        ImageView iv_blackname_del;
    }

2：生成ViewHolder的對(duì)象

 ViewHolder viewHolder = new ViewHolder();

3:如果是第一次

完整的

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            ViewHolder viewHolder = new ViewHolder();
            if (convertView==null){
                convertView = View.inflate(MainActivity.this, R.layout.item, null);
                viewHolder.textView= (TextView)convertView.findViewById(R.id.te);
                convertView.setTag(viewHolder);
            }else {
                viewHolder = (ViewHolder) convertView.getTag();
            }

            viewHolder.textView.setText(object[position]);
            return convertView;
        }
    }

    static class ViewHolder{
        TextView textView;
    }
