自定義封裝 banner 組件，供大家參考，具體內容如下
1. 效果圖預覽
2.基本功能
一個簡單方便的輪播圖組件，基于viewpager 基礎上進行的封裝。
可設置 項目中圖片，網絡圖片， View；

3.基本實現
1）. 自定義屬性
<declare-styleable name="BannerLayoutStyle"> <attr name="maskStartColor" format="color|reference" /> <attr name="maskEndColor" format="color|reference" /> <attr name="selectedIndicatorColor" format="color|reference" /> <attr name="unSelectedIndicatorColor" format="color|reference" /> <attr name="indicatorShape" format="enum"> <enum name="rect" value="0" /> <enum name="oval" value="1" /> </attr> <attr name="selectedIndicatorHeight" format="dimension|reference" /> <attr name="selectedIndicatorWidth" format="dimension|reference" /> <attr name="unSelectedIndicatorHeight" format="dimension|reference" /> <attr name="unSelectedIndicatorWidth" format="dimension|reference" /> <attr name="indicatorPosition" format="enum"> <enum name="centerBottom" value="0" /> <enum name="rightBottom" value="1" /> <enum name="leftBottom" value="2" /> <enum name="centerTop" value="3" /> <enum name="rightTop" value="4" /> <enum name="leftTop" value="5" /> </attr> <attr name="indicatorSpace" format="dimension|reference" /> <attr name="indicatorMargin" format="dimension|reference" /> <attr name="autoPlayDuration" format="integer|reference" /> <attr name="scrollDuration" format="integer|reference" /> <attr name="isAutoPlay" format="boolean" /> <attr name="defaultImage" format="integer|reference" /> <attr name="isIndicatorVisible" format="boolean" /> <attr name="cornerRadii" format="dimension|reference" /> </declare-styleable>
2）.基本方法
//添加本地圖片路徑public void setViewRes(List<Integer> viewRes) {。。。}//添加網絡圖片路徑public void setViewUrls(List<String> urls) {。。。}//添加任意View視圖private void setViews2(final List<View> views) {。。。}// 設置是否允許 循環 public void setLoop(boolean loop) { } // 設置是否可以滑動 public void setSlideable(boolean slideable) { }更多用法 詳見代碼，這里就不全部粘貼了。
3）.使用示例：
<com.dzq.widget.CustomBannerView android:id="@+id/banner" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight="1" app:autoPlayDuration="2000" app:defaultImage="@drawable/bg_banner" app:indicatorMargin="@dimen/indicatorMargin" app:indicatorPosition="rightBottom" app:indicatorShape="oval" app:indicatorSpace="@dimen/indicatorSpace" app:isAutoPlay="true" app:isIndicatorVisible="true" app:scrollDuration="1000" app:selectedIndicatorColor="@color/color_ec407a" app:selectedIndicatorHeight="5dp" app:selectedIndicatorWidth="5dp" app:unSelectedIndicatorColor="@color/color_71d9e7" app:unSelectedIndicatorHeight="5dp" app:unSelectedIndicatorWidth="5dp" /> <com.dzq.widget.CustomBannerView android:id="@+id/banner2" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="5dp" android:layout_weight="1" app:autoPlayDuration="2000" app:defaultImage="@drawable/bg_banner" app:indicatorMargin="@dimen/indicatorMargin" app:indicatorPosition="rightBottom" app:indicatorShape="rect" app:indicatorSpace="@dimen/indicatorSpace" app:isAutoPlay="false" app:isIndicatorVisible="true" app:scrollDuration="1000" app:selectedIndicatorColor="@color/color_ec407a" app:selectedIndicatorHeight="5dp" app:selectedIndicatorWidth="10dp" app:unSelectedIndicatorColor="@color/color_71d9e7" app:unSelectedIndicatorHeight="10dp" app:unSelectedIndicatorWidth="5dp" /> <com.dzq.widget.CustomBannerView android:id="@+id/banner3" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="5dp" android:layout_weight="1" app:cornerRadii="5dp" app:indicatorMargin="@dimen/indicatorMargin" app:indicatorPosition="centerTop" app:indicatorShape="rect" app:indicatorSpace="@dimen/indicatorSpace" app:isAutoPlay="false" app:isIndicatorVisible="true" app:maskEndColor="#00000000" app:maskStartColor="#99000000" app:scrollDuration="1000" app:selectedIndicatorColor="#00CAA9" app:selectedIndicatorHeight="10dp" app:selectedIndicatorWidth="25dp" app:unSelectedIndicatorColor="#26000000" app:unSelectedIndicatorHeight="10dp" app:unSelectedIndicatorWidth="10dp" />
