最核心的类是SliderLayout,他继承自相对布局,包含了可以左右滑动的SliderView,以及页面指示器PagerIndicator。这两部分都可以自定义。
AndroidImageSlider常规用法:使用TextSliderView+自定义PagerIndicator。
用法
1. 添加依赖
compile ‘com.squareup.picasso:picasso:2.3.2‘
compile ‘com.nineoldandroids:library:2.4.0‘
compile ‘com.daimajia.slider:library:1.1.5@aar‘
2. 布局文件中放置SliderLayout以及PagerIndicator
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:custom="http://schemas.android.com/apk/res-auto" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <com.daimajia.slider.library.SliderLayout android:id="@+id/slider" android:layout_width="match_parent" android:layout_height="200dp" />
//指示器的类型 <com.daimajia.slider.library.Indicators.PagerIndicator android:id="@+id/custom_indicator" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center" custom:selected_color="#FF5500" custom:unselected_color="#55333333" custom:shape="rect" custom:selected_padding_left="2dp" custom:selected_padding_right="2dp" custom:unselected_padding_left="2dp" custom:unselected_padding_right="2dp" custom:selected_width="16dp" custom:selected_height="3dp" custom:unselected_width="16dp" custom:unselected_height="3dp" android:layout_gravity="center" /> </LinearLayout>
3.代码实现:
实例化若干个TextSliderView,对其设置好图片,文字以及相应的监听事件,最后添加到SliderLayout中。
可以对SliderLayout进行一些设置,如设置指示器类型,动画,延时时间等,
最后别忘了在布局摧毁的时候,调用sliderLayout.stopAutoCycle();方法停止广告的轮播,以释放资源。
