Usage(ECardFlow)

Step 1. Add the JitPack repository to your build file

allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}
}

Step 2. Add the dependency

dependencies {
compile 'com.github.codeestX:ECardFlow:v1.0.5'
}

Step 3. Just use it as a ViewPager

<moe.codeest.ecardflow.ECardFlow
android:id="@+id/ecardflow"
android:layout_width="280dp"
android:layout_height="match_parent"
app:expandMode="slide_up"
app:expandTime="700"
app:switchTime="1200"
app:preloadPageNum="3"
app:maxRotateY="5">

• Only support fragment as each page
• For best performance, giving ECardFlow's parent view an attrandroid:clipChildren="false",and do NOT set ECardFlow's width asmatch_parent
• See DemoProject for more details

Attrs:

<declare-styleable name="attr">
<!-- Page switching time, default 1200ms -->
<attr name="switchTime" format="integer" />
<!-- Page expanding time, default 700ms -->
<attr name="expandTime" format="integer" />
<!-- Page expanding mode, click or slide up to expand, default slide_up -->
<attr name="expandMode">
<enum name="slide_up" value="10" />
<enum name="click" value="11" />
</attr>
<!-- The number of pages outside the screen, default 3 -->
<attr name="preloadPageNum" format="integer" />
<!-- The shortest sliding distance to trigger the switch, default context.getScaledTouchSlop() -->
<attr name="touchSlop" format="integer" />
<!-- The maximum angle of rotation, default 5 -->
<attr name="maxRotateY" format="integer" />
</declare-styleable>

Java Code:

mEcardflow.gotoNext();
mEcardflow.gotoLast();
mEcardflow.expand();
mEcardflow.shrink();
mEcardflow.isExpanding();
mEcardflow.setTouchSlop(slop);
mEcardflow.setExpandTime(time);
mEcardflow.setOnExpandStateListener(new ECardFlow.OnExpandStateListener() {
@Override
public void onExpand(View page, int position) {
}
@Override
public void onShrink(View page, int position) {
}
});

Usage(ECardFlowLayout)

Step 1. Add the JitPack repository to your build file

allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}
}

Step 2. Add the dependency

dependencies {
compile 'com.github.codeestX:ECardFlow:v1.0.5'
}

Step 3. Just put a ViewPager in ECardFlowLayout

<moe.codeest.ecardflow.ECardFlowLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ecardflow_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipChildren="false">
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="240dp"
android:layout_height="270dp"
android:layout_gravity="center_horizontal|bottom"
android:layout_marginBottom="80dp"/>
</moe.codeest.ecardflow.ECardFlowLayout>

Step 4. setAnimMode & setImageProvider

mVPLayout = (ECardFlowLayout) findViewById(R.id.ecardflow_layout);
mVPLayout.setAnimMode(new BlurAnimMode());
mVPLayout.setImageProvider(new DrawableImageProvider(this, res, width, height);

• Set AnimMode before Set ImageProvider
• Use mVPLayout.onDestroy(); to release source
• See DemoProject for more details

Attrs:

<declare-styleable name="attr_layout">
<!-- The duration of Page switching animation, default 300ms -->
<attr name="switchAnimTime" format="integer" />
</declare-styleable>

Java Code:

	mVPLayout.setImageProvider(imageProvider);
mVPLayout.setAnimMode(animMode);
mVPLayout.setSwitchAnimTime(time);
//maxSize = Runtime.getRuntime().maxMemory();
//default: maxSize / 5
//min: maxSize / 8
mVPLayout.setCacheSize(megabytes);
mVPLayout.onDestroy();

AnimMode	Des
DefaultAnimMode	No Effect
BlurAnimMode	Blur Effect
MoveAnimMode	Parallax Effect
ScaleAnimMode	Scale Effect
CrossMoveAnimMode	Cross Parallax Effect

You can custom AnimMode with class which implements AnimMode

ImageProvider	Des
DrawableImageProvider	Prividing resId(R.drawable/mipmap.xx) as image resource
PathImageProvider	Prividing file path as image resource
FileImageProvider	Prividing File as image resource

You can custom ImageProvider with class which implements ImageProvider

If you choose BlurAnimMode, you can enable RenderScript for a high performance.

Open the build.gradle file in the app folder of your application module.
Add the following RenderScript settings to the file:

 android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
minSdkVersion 9
targetSdkVersion 19
//Enable RenderScript
renderscriptTargetApi 23
renderscriptSupportModeEnabled true
}
}
