daimajia一个关于图片轮播开源项目AndroidImageSlider,先看下效果图。
幻灯片切换动画效果,可直接从网络或本地文件中获取图片。点击图片开始/暂停,滑动等待几秒后重新开始轮播。
Step1:
Gradle
compile "com.android.support:support-v4:+"
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.nineoldandroids:library:2.4.0'
compile 'com.daimajia.slider:library:1.1.5@aar'
compile 'com.daimajia.androidanimations:library:1.1.3@aar'
Step2:
Add permissions (if necessary) to your AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Step3:
Add the Slider to your layout:
<com.daimajia.slider.library.SliderLayout
android:id="@+id/slider"
android:layout_width="match_parent"
android:layout_height="200dp"
/>
There are some default indicators. If you want to use a provided indicator:
<com.daimajia.slider.library.Indicators.PagerIndicator
android:id="@+id/custom_indicator"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
/>
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
<com.daimajia.slider.library.SliderLayout
android:id="@+id/slider1"
android:layout_width="match_parent"
custom:pager_animation="Accordion"
custom:auto_cycle="true"
custom:indicator_visibility="visible"
custom:pager_animation_span="1100"
android:layout_height="200dp"/>
自定义指示器:
custom:shape=”oval” 或 rect 圆形,矩形
"@+id/custom_indicator"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
custom:selected_color="#0095BF"
custom:unselected_color="#55333333"
custom:selected_drawable="@drawable/bird"
custom:shape="oval"
custom:selected_padding_left="5dp"
custom:selected_padding_right="5dp"
custom:unselected_padding_left="5dp"
custom:unselected_padding_right="5dp"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
custom:selected_width="6dp"
custom:selected_height="6dp"
custom:unselected_width="6dp"
custom:unselected_height="6dp"
android:layout_marginBottom="40dp"
/>
"@+id/custom_indicator2"
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
用代码设置:
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()){
TextSliderView textSliderView = new TextSliderView(this);
// initialize a SliderLayout
textSliderView
.description(name)
.image(url_maps.get(name))
.setScaleType(BaseSliderView.ScaleType.Fit)
.setOnSliderClickListener(this);
//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)
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);
如果想改变默认Indicator颜色等,修改library相关xml文件。
提示:既然能自定义下方指示器,是不是可以用做导航页的开发?
