Android Arsenal travis-ic Showcase Sliding cards with pretty gallery effects.

Download

Include the following dependency in your build.gradle file. Gradle:
    repositories {
jcenter()
}
dependencies {
compile 'com.mxn.soul:slidingcard-core:1.3.1'
}

Usage

For a working implementation of this project see the app/ folder. 1.Add the com.mxn.soul.slidingcard_core.ContainerView to your layout XML file. activity_main.xml:
    <RelativeLayout xmlns:android=""
xmlns:tools=""
xmlns:card=""
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MainActivity">
<com.mxn.soul.slidingcard_core.ContainerView
android:id="@+id/contentview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
card:card_item_height = "230dp"
card:card_item_margin = "10dp"
/>
</RelativeLayout>
card_item_height need to be bigger than the height of your photo or any view you create for each item . if you want the first view smaller than the second one to get a beautiful screen,you need to set card_item_margin 2.Create your own layout for the card sliding_card_item.xml
    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="@+id/sliding_card_content_view"
xmlns:android=""
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingBottom="20dp">
<ImageView
android:id="@+id/user_imageview"
android:layout_width="fill_parent"
android:layout_height="200dp"
android:layout_margin="10dp"
android:background="#ffffff"
android:padding="5dp"
android:scaleType="fitXY"
android:contentDescription="@string/app_name"/>
<TextView
android:id="@+id/user_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="@id/user_imageview"
android:layout_marginBottom="5dp"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:background="#90575E6A"
android:padding="5dp"
android:textColor="#ffffff"
android:textSize="14sp"/>
</RelativeLayout>
3.implements ContainerView.ContainerInterface and override initCard(),exChangeCard()
public class MainActivity extends ActionBarActivity implements ContainerView.ContainerInterface {
private ContainerView contentView;
private List<PhotoContent> dataList ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
contentView = (ContainerView) findViewById(R.id.contentview);
initData() ;
}
private void initData(){
dataList = new ArrayList<>();
String[] titles = getResources().getStringArray(R.array.title) ;
String[] imgs = getResources().getStringArray(R.array.imgs) ;
for(int n = 0 ; n < titles.length;n++){
PhotoContent photoContent = new PhotoContent(String.valueOf(n),titles[n],imgs[n]) ;
dataList.add(photoContent) ;
}
contentView.initCardView(MainActivity.this,R.layout.sliding_card_item,R.id
.sliding_card_content_view);
}
@Override
public void initCard(SlidingCard card, int index) {
ImageView mImageView = (ImageView) card.findViewById(R.id.user_imageview);
TextView mTextView = (TextView) card.findViewById(R.id.user_text);
if (dataList.get(index) != null) {
mTextView.setText(dataList.get(index).getTitle());
mImageView.setImageResource(getResourceByReflect(dataList.get(index).getUrl()));
mImageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//the first card index must be 0
Toast.makeText(MainActivity.this, dataList.get(0).getTitle(), Toast
.LENGTH_SHORT).show();
}
});
}
}
@Override
public void exChangeCard() {
PhotoContent item = dataList.get(0);
dataList.remove(0);
dataList.add(item);
}
// you can ues UniversalImageLoader,Fresco etc to display image ,and replace the method
public int getResourceByReflect(String imageName) {
Class drawable = R.drawable.class;
Field field ;
int r_id;
try {
field = drawable.getField(imageName);
r_id = field.getInt(field.getName());
} catch (Exception e) {
r_id = R.drawable.img1;
Log.e("ERROR", String.valueOf(e.getMessage()));
}
return r_id;
}
}
contentView.initCardView() need to set you own layout's name ,and the root's id . example: initCardView(ContainerInterface mContainerInterface,int layoutId,int rootId). it's easy to set new ArrayList() to store the data , but make sure the list's size is more than 3 . if you put it in scrollable viewgroup like listview ,viewpager etc..,drag will not work normally, I provide a method to avoid scroll conflict:
    public void setScrollableGroups(ViewGroup...args)
do this after contentView's Initialization:
    contentView = (ContainerView) view.findViewById(R.id.contentview);
contentView.setScrollableGroups(viewPager, listview) ;
contentView.initCardView(MyFragment.this, R.layout.sliding_card_item, R.id
.sliding_card_content_view);

TODO

Optimized memory

V1.7

support SlidingCard with Fragment. Add method to solve scroll conflict.

V1.6

make it easier to use.

V1.5

解决了滑动过快导致最后一张加载没有显示的bug。 加入了一个全局变量 public static boolean sScrolling = false ;来记录全局滑动状态, 在滑动过程中去掉其他卡片的监听,滑动之后再加入监听。

V1.4

优化滑动动画流畅性,图片可以根据手势旋转。

V1.3

支持自定义多张照片.可支持任意张照片,但是一次只会显示最前面的三张,随着滑动翻页,依次向后加载,加载完毕后循环从第一张加载。

V1.2

修复了左滑和右滑图片出现BUG的问题.

V1.1

解决了锯齿问题。 在SlidingCard的dispatchDraw方法中加入以下代码:
        PaintFlagsDrawFilter pfd = new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG|Paint
.FILTER_BITMAP_FLAG);
canvas.setDrawFilter(pfd);
在初始化时关闭view级别硬件加速(3.0以后版本有效)。 由于硬件加速并不支持所有的2D图形绘制操作,因此对于自定义的View和绘制调用来说,会造成影响。 对于这个问题,通常是对那些不可见的元素进行了异常或错误的像素渲染。为了避免这种问题,需要关闭硬件加速。
 if(android.os.Build.VERSION.SDK_INT>=11)
{
setLayerType(LAYER_TYPE_SOFTWARE, null);
}
以上两个步骤缺一不可。

V1.0

支持三张照片展示,手势滑动等。 需要改进的地方: 1、抗锯齿(做了基本优化,还需改进) 2、支持自定义多张照片 3、滑动动画流畅性需要优化 4、同时左滑和右滑会有bug 5、滑动过快导致最后一张加载没有显示 6、内存优化
