SimpleViewPager

That image ViewPager you have to code for every Android project - use this instead.

Usage

Add to your Android layout xml:

<eu.fiskur.simpleviewpager.SimpleViewPager
  android:id="@+id/simple_view_pager"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  />

set Image scale type, and vertical attributes (see note below):

<eu.fiskur.simpleviewpager.SimpleViewPager
  xmlns:simpleviewpager="http://schemas.android.com/apk/res-auto"
  android:id="@+id/simple_view_pager"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  simpleviewpager:vertical="true"
  simpleviewpager:scaleType="CENTER_CROP"
  />

Then add your images, and setup Picasso ( or Glide, Fresco, or whatever):

SimpleViewPager simpleViewPager = (SimpleViewPager) findViewById(R.id.simple_view_pager);
  String[] demoUrlArray = new String[]{

"http://fiskur.eu/apps/simpleviewpagerdemo/001.jpg",

"http://fiskur.eu/apps/simpleviewpagerdemo/002.jpg",

"http://fiskur.eu/apps/simpleviewpagerdemo/003.jpg",

"http://fiskur.eu/apps/simpleviewpagerdemo/004.jpg",

"http://fiskur.eu/apps/simpleviewpagerdemo/005.jpg", 
}
;  //or use resources shipped with the app. eg: /* int[] resourceIds = new int[]{
 
 R.drawable.a, 
 R.drawable.b, 
 R.drawable.c, 
 R.drawable.d, 
 R.drawable.e 
}
 */  simpleViewPager.setImageUrls(demoUrlArray, new ImageURLLoader() {

  @Override

  public void loadImage(ImageView view, String url) {

Picasso.with(MainActivity.this).load(url).into(view);

  
}

 
}
);
  //optional: int indicatorColor = Color.parseColor("#ffffff");
 int selectedIndicatorColor = Color.parseColor("#fff000");
 simpleViewPager.showIndicator(indicatorColor, selectedIndicatorColor);

If you're using resources that ship with your app make life easy and let Picasso handle the memory management/downsampling and use an array of resources IDs. You can also set the ScaleType for the images (or again; leave that to Picasso in the callback).

Add a ViewPager.OnPageChangeListener if needed: simpleViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() { ... } );

Always call simpleViewPager.clearListeners() when the activity/fragment is destroyed to avoid leaks.

Vertical View Pager

You can add simpleviewpager:vertical="true" to your layout xml to get a ViewPager that scrolls vertically, there's quite a few VerticalViewPager solutions around but most are old and unmaintained.

<eu.fiskur.simpleviewpager.SimpleViewPager
  android:id="@+id/simple_view_pager"
  xmlns:simpleviewpager="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  simpleviewpager:vertical="true"/>

There's an additional circlesPaddingBottom in case you're using a BottomSheet floating over the SimpleViewPager and want to offset the pager indicators so they're still onscreen, or aligned vertically central onscreen:

<eu.fiskur.simpleviewpager.SimpleViewPager
  android:id="@+id/simple_view_pager"
  xmlns:simpleviewpager="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  simpleviewpager:vertical="true"
  simpleviewpager:scaleType="CENTER_CROP"
  simpleviewpager:circlesPaddingBottom="60dp"/>

##Dependency

Add jitpack.io to your root build.gradle, eg:

allprojects {

  repositories {

jcenter()

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

  
}
 
}

then add the dependency to your project build.gradle:

dependencies {

  compile fileTree(dir: 'libs', include: ['*.jar'])
  compile 'com.github.fiskurgit:SimpleViewPager:1.0.10' 
}

You can find the latest version in the releases tab above: https://github.com/fiskurgit/SimpleViewPager/releases
