列表（listview）实现CheckBox全选效果

思路：在实体类中增加是否选中的标志位加以控制，点击全选遍历整个集合
1实体类中

public boolean isCheck;

2适配器的getView中

viewHolder.cbShopCar.setChecked(data.get(position).isCheck);

3activity中点击触发

  allSelectDelete.setOnClickListener(new View.OnClickListener() {
    
    
            @Override
            public void onClick(View v) {
    
    
                for (int i = 0; i < records.size(); i++) {
    
    
                    records.get(i).isCheck = true;
                }
                lvFoot.setAdapter(new ShopCarLvAdapter(records, ShopCarActivity.this));
//                mAdapter.notifyDataSetChanged();

            }
        });

实现取消全选

allSelectDelete.setOnClickListener(new View.OnClickListener() {
    
    
            @Override
            public void onClick(View v) {
    
    
                if (allSelectDelete.isChecked()) {
    
    
                    for (int i = 0; i < records.size(); i++) {
    
    
                        records.get(i).isCheck = true;
                    }
                } else {
    
    
                    for (int i = 0; i < records.size(); i++) {
    
    
                        records.get(i).isCheck = false;
                    }
                }

                lvFoot.setAdapter(new ShopCarLvAdapter(records, ShopCarActivity.this));
//                mAdapter.notifyDataSetChanged();

            }
        });
