【移動應(yīng)用開發(fā)技術(shù)】Android如何實現(xiàn)炫酷輪播圖效果

這篇文章將為大家詳細(xì)講解有關(guān)Android如何實現(xiàn)炫酷輪播圖效果，在下覺得挺實用的，因此分享給大家做個參考，希望大家閱讀完這篇文章后可以有所收獲。輪播圖的實現(xiàn)有很多種方式，早先我在網(wǎng)上看了下別人寫的輪播圖，感覺都比較的墨守成規(guī)，有的還有可能加載不了網(wǎng)絡(luò)圖片。所以我在這里自己重新寫了下輪播圖，方便日后的項目使用.效果圖：這只是其中的一種效果底層封裝的我在下面會一一展示，先看下在MainActivity中怎樣調(diào)取這個輪播控件package

}那么下面我就來封裝Volley請求網(wǎng)絡(luò)數(shù)據(jù)框架，封裝好了之后，調(diào)用在MainActivity中有體現(xiàn)。首先，VolleyRequest類如下：package

com.wujie.advertisment.volley;

import

android.content.Context;

import

android.util.Log;

import

com.android.volley.RequestQueue;

import

com.android.volley.Response;

};

mRequestQueue.add(request);

return

{

request

=

new

mRequestQueue.add(request);

return

request;

}

}GsonRequest類：package

return

Response.error(new

}

}

@Override

protected

void

deliverResponse(T

response)

{

mListener.onResponse(response);

}

}管理接口的類：package

com.wujie.advertisment.volley;

import

java.util.HashMap;

import

java.util.Map;

/**

*

public

class

IpAddressConstants

{

public

static

String

MYIP="http://xxxxx:8080/";

/**

======輪播圖======

*/

public

static

final

String

ADVERTISMENT_URL=MYIP+"AppInterface/advert/indexAdvert";

/**

(wujie)增加代碼

usage:獲取輪播圖需要的Map數(shù)據(jù)*/

public

static

Map<String,String>

getAdnertisment(String

city,String

token){

Map<String,String>

mMap=new

HashMap<>();

mMap.put("city_name",city);//這個key是你要上傳參數(shù)的的key,服務(wù)器通過這個key來獲取客戶端穿的參數(shù)。

mMap.put("token",token);

return

mMap;

}

}封裝好后，我們要將Volley請求加入到隊列中（初始化）：package
