可配置的属性

 <declare-styleablename="LoopViewPager">

<attrname="animTime"format="integer" />
<!-- 动画效果 -->
<attrname="animStyle"format="enum">
<!-- 折叠效果 -->
<enumname="accordion"value="1" />
<enumname="accordionUp"value="2" />
<!-- 立方体效果 -->
<enumname="cube"value="3" />
<enumname="cubeUp"value="4" />
</attr>
<!-- 是否可以手动滚动页面，默认true -->
<attrname="scrollEnable"format="boolean" />
<!-- 触摸页面是否停止轮播，默认true -->
<attrname="touchEnable"format="boolean" />
</declare-styleable>
<declare-styleablename="LoopDotsView">
<!-- 圆点大小 -->
<attrname="dotSize"format="integer|dimension|reference" />
<!-- 圆点宽度 -->
<attrname="dotWidth"format="integer|dimension|reference" />
<!-- 圆点高度 -->
<attrname="dotHeight"format="integer|dimension|reference" />
<!-- 圆点距离 -->
<attrname="dotRange"format="integer|dimension|reference" />
<!-- 圆点形状 -->
<attrname="dotShape">
<!-- 矩形，默认值 -->
<enumname="rectangle"value="1" />
<!-- 圆形 -->
<enumname="oval"value="2" />
<!-- 三角形 -->
<enumname="triangle"value="3" />
<!-- 菱形 -->
<enumname="diamond"value="4" />
</attr>
<!-- 圆点颜色，默认值0xFFFFFFFF -->
<attrname="dotColor"format="color|reference" />
<!-- 圆点选中颜色，默认值0x55000000 -->
<attrname="dotSelectColor"format="color|reference" />
<!-- 圆点资源 -->
<attrname="dotResource"format="reference" />
<!-- 圆点选中资源 -->
<attrname="dotSelectResource"format="reference" />
</declare-styleable>

配置说明

• 1、loopTime的值应不小于1s，如果值为0，则不自动轮播；
• 2、animTime的值应小于loopTime；
• 3、dotWidth、dotHeight、dotRange如果没有设置，则默认值为dotSize；
• 4、如果设置了dotResource、dotSelectResource，则dotShape、dotColor、dotSelectColor配置不生效；
• 5、轮播调用start()方法，停止轮播调用stop()方法，start前至少设置setImgData、setImgLength、setTitleData中的其中一个；

如何自定义

publicclassSimpleDemo2extendsAppCompatActivity {
privateList<View> viewList;
privateLoopViewPagerloopViewPager;
@OverrideprotectedvoidonCreate(BundlesavedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_simple_demo2);
loopViewPager = (LoopViewPager) findViewById(R.id.lvp_pager);
initData();
// 自定义ViewloopViewPager.setOnCreateItemViewListener(newOnCreateItemViewListener() {
@OverridepublicViewgetItemView(intposition) {
returnviewList.get(position);
}
});
//处理点击事件loopViewPager.setOnItemClickListener(newOnItemClickListener() {
@OverridepublicvoidonItemClick(Viewview, intposition) {
Toast.makeText(SimpleDemo2.this, "position=" + position, Toast.LENGTH_SHORT).show();
}
});
// 自定义动画loopViewPager.setPageTransformer(1500, newLoopVerticalTransformer() {
@OverridepublicvoidtransformViewPage(Viewview, floatposition) {
view.setPivotX(view.getMeasuredWidth() * 0.5f);
view.setPivotY(position <= 0 ? view.getMeasuredHeight() : 0);
view.setRotationX(-90f * position);
}
});
loopViewPager.setImgLength(viewList.size());
// loopViewPager.setTitleData(DataFactory.titleListString());loopViewPager.start();
}
privatevoidinitData() {
viewList = newArrayList<>();
for (inti = 1; i <= 5; i++) {
Viewview = null;
if (i == 2) {
ImageViewimageView = newImageView(this);
Glide.with(SimpleDemo2.this).load("http://pic.58pic.com/58pic/13/72/07/55Z58PICKka_1024.jpg").centerCrop().into(imageView);
