android一键实现图片轮播（AndroidImageSlider）

轮播图在APP开发里面，几乎成为一个必备的功能，今天介绍一下AndroidImageSlider，
使用起来相对简便，开发快速，感谢android程序员们的开源精神。

一、首先引入主要相关的库：

dependencies {
        compile 'com.squareup.picasso:picasso:2.3.2'
        compile 'com.nineoldandroids:library:2.4.0'
        compile 'com.daimajia.slider:library:1.1.5@aar'
}

二、布局展示：

根布局加上

 xmlns:custom="http://schemas.android.com/apk/res-auto"

---

轮播图的位置：

  

关键参数设置： 
custom:pager_animation=”Accordion” 切换动画效果 
custom:auto_cycle=”true” 自动播放 
custom:indicator_visibility=”visible” 显示指示器

---

指示器的位置：

1.默认指示器：

   style="@style/AndroidImageSlider_Corner_Oval_Orange"
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        android:layout_marginBottom="20dp"
        />

可用 style设置基本参数 

默认提供三种: 
AndroidImageSlider_Corner_Oval_Orange，AndroidImageSlider_Attractive_Rect_Blue，AndroidImageSlider_Magnifier_Oval_Black




2.自定义指示器：

    

custom:shape=”oval” 或 rect 圆形，矩形

 custom:selected_drawable="@mipmap/bird"当前的点

三、设置使用：

private SliderLayout mDemoSlider1;

mDemoSlider1 = (SliderLayout)findViewById(R.id.slider1);

HashMap url_maps = new HashMap();
        url_maps.put("Hannibal", "http://static2.hypable.com/wp-content/uploads/2013/12/hannibal-season-2-release-date.jpg");
        url_maps.put("Big Bang Theory", "http://tvfiles.alphacoders.com/100/hdclearart-10.png");
        url_maps.put("House of Cards", "http://cdn3.nflximg.net/images/3093/2043093.jpg");
        url_maps.put("Game of Thrones", "http://images.boomsbeat.com/data/images/full/19640/game-of-thrones-season-4-jpg.jpg");
//        HashMap file_maps = new HashMap();
//        file_maps.put("Hannibal",R.drawable.nemo);
//        file_maps.put("Big Bang Theory",R.drawable.up);
//        file_maps.put("House of Cards",R.drawable.wall);
//        file_maps.put("Game of Thrones", R.drawable.toystory);
        for(String name : url_maps.keySet()){
            // DefaultSliderView sliderView = new DefaultSliderView(this);
            TextSliderView textSliderView = new TextSliderView(this);
            // initialize a SliderLayout
            textSliderView
                    .description(name)
                    .image(url_maps.get(name))
                    .setScaleType(BaseSliderView.ScaleType.Fit)
                    .setOnSliderClickListener(this);//点击轮播图

            //add your extra information 点击图片时可用到
            textSliderView.bundle(new Bundle());
            textSliderView.getBundle()
                    .putString("extra",name);

            mDemoSlider1.addSlider(textSliderView);
        }
       // 设置默认过渡效果(可在xml中设置)
           //mDemoSlider.setPresetTransformer(SliderLayout.Transformer.Default);
          mDemoSlider1.setPresetTransformer(SliderLayout.Transformer.Accordion);
        // 设置默认指示器位置(默认指示器白色,位置在sliderlayout底部)
        mDemoSlider1.setPresetIndicator(SliderLayout.PresetIndicators.Center_Bottom);
        // 设置自定义指示器(位置自定义)
        mDemoSlider1.setCustomIndicator((PagerIndicator) findViewById(R.id.custom_indicator));
        // 设置TextView自定义动画
        mDemoSlider1.setCustomAnimation(new DescriptionAnimation());
        //mDemoSlider2.setCustomAnimation(new ChildAnimationExample()); // 多种效果，进入该类修改，参考效果github/daimajia/AndroidViewAnimations
        // 设置持续时间
        mDemoSlider1.setDuration(2000);
        mDemoSlider1.addOnPageChangeListener(this);//轮播图轮播监听

相关介绍：

1. 过渡效果： mDemoSlider.setPresetTransformer(“？？？？？”).

    相关值有：
   
       Default("Default"),
       Accordion("Accordion"),
       Background2Foreground("Background2Foreground"),
       CubeIn("CubeIn"),
       DepthPage("DepthPage"),
       Fade("Fade"),
       FlipHorizontal("FlipHorizontal"),
       FlipPage("FlipPage"),
       Foreground2Background("Foreground2Background"),
       RotateDown("RotateDown"),
       RotateUp("RotateUp"),
       Stack("Stack"),
       Tablet("Tablet"),
       ZoomIn("ZoomIn"),
       ZoomOutSlide("ZoomOutSlide"),
       ZoomOut("ZoomOut");
   
   即为："Default","Accordion", "Background2Foreground","CubeIn","DepthPage","Fade","FlipHorizontal", "FlipPage","Foreground2Background"，"RotateDown"，"RotateUp","Stack",  "Tablet","ZoomIn","ZoomOutSlide","ZoomOut";
   

2. mDemoSlider.setCustomIndicator((PagerIndicator) findViewById(R.id.custom_indicator));
   设置自定义指示器样式和位置，在上面表述的xml中（2.自定义指示器：），

3. mDemoSlider.setCustomAnimation(new DescriptionAnimation());

mDemoSlider.setCustomAnimation(new ChildAnimationExample());
自定义指示器动画，这里提供了一个：

package com.ddv.www.myshufflingfiguredemo;

import android.util.Log;
import android.view.View;

import com.daimajia.androidanimations.library.attention.StandUpAnimator;
import com.daimajia.slider.library.Animations.BaseAnimationInterface;

public class ChildAnimationExample implements BaseAnimationInterface {

    private final static String TAG = "ChildAnimationExample";

    @Override
    public void onPrepareCurrentItemLeaveScreen(View current) {
        View descriptionLayout = current.findViewById(com.daimajia.slider.library.R.id.description_layout);
        if(descriptionLayout!=null){
            current.findViewById(com.daimajia.slider.library.R.id.description_layout).setVisibility(View.INVISIBLE);
        }
        Log.e(TAG,"onPrepareCurrentItemLeaveScreen called");
    }

    @Override
    public void onPrepareNextItemShowInScreen(View next) {
        View descriptionLayout = next.findViewById(com.daimajia.slider.library.R.id.description_layout);
        if(descriptionLayout!=null){
            next.findViewById(com.daimajia.slider.library.R.id.description_layout).setVisibility(View.INVISIBLE);
        }
        Log.e(TAG,"onPrepareNextItemShowInScreen called");
    }

    @Override
    public void onCurrentItemDisappear(View view) {
        Log.e(TAG,"onCurrentItemDisappear called");
    }

    @Override
    public void onNextItemAppear(View view) {

        View descriptionLayout = view.findViewById(com.daimajia.slider.library.R.id.description_layout);
        if(descriptionLayout!=null){
            view.findViewById(com.daimajia.slider.library.R.id.description_layout).setVisibility(View.VISIBLE);
//            ValueAnimator animator = ObjectAnimator.ofFloat(
//                    descriptionLayout, "y", -descriptionLayout.getHeight(),
//                    0).setDuration(500);
//            animator.start();
//            new BounceInAnimator().animate(descriptionLayout);
            new StandUpAnimator().animate(descriptionLayout);
        }

        Log.e(TAG,"onCurrentItemDisappear called");
    }
}

注意，项目中要引入：

compile 'com.daimajia.androidanimations:library:1.0.3@aar'

4.mDemoSlider1.setPresetIndicator(SliderLayout.PresetIndicators.Center_Bottom);
设置默认指示器位置(默认指示器白色,位置在sliderlayout底部)

相关值有：

   Center_Bottom("Center_Bottom",R.id.default_center_bottom_indicator),
        Right_Bottom("Right_Bottom",R.id.default_bottom_right_indicator),
        Left_Bottom("Left_Bottom",R.id.default_bottom_left_indicator),
        Center_Top("Center_Top",R.id.default_center_top_indicator),
        Right_Top("Right_Top",R.id.default_center_top_right_indicator),

到这里AndroidImageSlider相关用法和介绍就完成了！
大家一起学习进步…..

最后祝大家冬至快乐哦…..
