Android 自定义内部接口

背景：适配器中数据变动需传出

解决：适配器中自定义监听接口，外部监听变化做出反应。

适配器中设置：

    private AddressNoListener addressNoListener;  //定义/*** 自定义接口*/public interface AddressNoListener{void addressNo(int position);  //确定传出的值}//设置 get setpublic AddressNoListener getAddressNoListener(){return addressNoListener;}public void setAddressNoListener(AddressNoListener addressNoListener)        {this.addressNoListener = addressNoListener;}   //有变动的地方 （需要监听的地方）viewHolder.deliveryAddressItemEdit.setOnClickListener(new View.OnClickListener() { @Overridepublic void onClick(View view) {//选择地址addressNoListener.addressNo(position); }});

外部获取：

        private DeliveryAddressAdapter addressAdapter;//先定义addressAdapter.setAddressNoListener(new DeliveryAddressAdapter.AddressNoListener() {@Overridepublic void addressNo(int addressNo) {//操作}});
