Usage

<com.jude.rollviewpager.RollPagerView
    android:layout_width="match_parent"
    android:layout_height="180dp"
    app:rollviewpager_play_delay="3000"/>

app:rollviewpager_play_delay="3000" period，unit is ms。0 for no auto-play。default is 0.
app:rollviewpager_hint_gravity="center" graviengty. left,center,right。default is center.

app:rollviewpager_hint_paddingTop="16dp"
app:rollviewpager_hint_paddingBottom="16dp"

Generally just need set the play_delay.

##HintView provide Hintview to DIY the indicator; setHintView(HintView hintview)

• HintView
  • ShapeHintView
    • IconHintView
    • ColorPointHintView
  • TextHintView

For example:

mRollViewPager.setHintView(new IconHintView(this,R.drawable.point_focus,R.drawable.point_normal));
mRollViewPager.setHintView(new ColorPointHintView(this, Color.YELLOW,Color.WHITE));
mRollViewPager.setHintView(new TextHintView(this));
mRollViewPager.setHintView(null);//hide the indicator

##ItemClickListener

mRollViewPager.setOnItemClickListener(new OnItemClickListener() {
  @Override
  public void onItemClick(int position) {
      Toast.makeText(MainActivity.this,"Item "+position+" clicked",Toast.LENGTH_SHORT).show();
  }
});

##Adapter There offer two Adapter for use conveniently.the RollViewPager can also user other PagerAdapter.

####StaticPagerAdapter this Adapter will store the every page(View), Once create multiple use.may take up more memory. Like FragmentPagerAdapter.this can use for any ViewPager;

####DynamicPagerAdapter this Adapter will not store the View.it create new View every time.save the memory. Like FragmentStatePagerAdapter.this can use for any ViewPager;

//the usage of the 2 adapter is same;
mRollViewPager.setAdapter(new TestNomalAdapter());
private class TestNomalAdapter extends StaticPagerAdapter{
    private int[] imgs = {
            R.drawable.img1,
            R.drawable.img2,
            R.drawable.img3,
            R.drawable.img4,
    };

    @Override
    public View getView(ViewGroup container, int position) {
        ImageView view = new ImageView(container.getContext());
        view.setImageResource(imgs[position]);
        view.setScaleType(ImageView.ScaleType.CENTER_CROP);
        view.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
        return view;
    }
    
    @Override
    public int getCount() {
        return imgs.length;
    }
}

####LoopPagerAdapter A loop adapter.realize by return MAX_INT in getCount(). same as StaticPagerAdapter in page store.Once create multiple use. this adapter only for RollViewPager. the usage is very simple。

mRollViewPager.setAdapter(new TestLoopAdapter(mRollViewPager));
private class TestLoopAdapter extends LoopPagerAdapter{
    private int[] imgs = {
            R.drawable.img1,
            R.drawable.img2,
            R.drawable.img3,
            R.drawable.img4,
    };
    
    public TestLoopAdapter(RollPagerView viewPager) {
        super(viewPager);
    }
    
    @Override
    public View getView(ViewGroup container, int position) {
        ImageView view = new ImageView(container.getContext());
        view.setImageResource(imgs[position]);
        view.setScaleType(ImageView.ScaleType.CENTER_CROP);
        view.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
        return view;
    }
    
    @Override
    public int getRealCount() {
        return imgs.length;
    }
}

Play Control

rollViewPager.pause()
rollViewPager.resume()
rollViewPager.isPlaying()
