RecyclerBanner

Auto play banner list view, implemented by recycler view.

Only one java class, it is tiny and clean.

How to use

1. define in xml layout:

<com.createchance.recyclerbanner.RecyclerBanner
        android:id="@+id/banner"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        app:autoPlaying="true"
        app:indicatorSelectedSrc="#00ff00"
        app:indicatorUnselectedSrc="@android:color/holo_green_light" />

2. define banner view layout(sample):

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tool="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/banner_img"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop"
        tool:background="#4c4c4c" />

    <TextView
        android:id="@+id/banner_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="10dp"
        android:layout_marginTop="10dp"
        android:textColor="@android:color/holo_orange_light"
        tool:text="@string/app_name" />

    <TextView
        android:id="@+id/banner_footer"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentEnd="true"
        android:layout_marginBottom="10dp"
        android:layout_marginEnd="10dp"
        android:textColor="@android:color/holo_orange_light"
        tool:text="@string/app_name" />

</RelativeLayout>

3. use in activity

recyclerBanner = findViewById(R.id.banner);
initBannerList();
recyclerBanner.setBannerCount(bannerList.size());
recyclerBanner.setRecyclerBannerCallback(new RecyclerBanner.RecyclerBannerCallback() {
    @Override
    public View createBannerView(ViewGroup parent) {
        View bannerView = getLayoutInflater().inflate(R.layout.banner_item, parent, false);

        bannerView.findViewById(R.id.banner_title).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                int pos = recyclerBanner.getCurrentPosition();
                Toast.makeText(MainActivity.this, "第" + pos + "个title被点击了", Toast.LENGTH_SHORT).show();
            }
        });

        bannerView.findViewById(R.id.banner_img).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                int pos = recyclerBanner.getCurrentPosition();
                Toast.makeText(MainActivity.this, "第" + pos + "个image被点击了", Toast.LENGTH_SHORT).show();
            }
        });

        bannerView.findViewById(R.id.banner_footer).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                int pos = recyclerBanner.getCurrentPosition();
                Toast.makeText(MainActivity.this, "第" + pos + "个footer被点击了", Toast.LENGTH_SHORT).show();
            }
        });

        return bannerView;
    }

    @Override
    public void switchBanner(int position, View bannerView) {
        Banner banner = bannerList.get(position);

        TextView title = bannerView.findViewById(R.id.banner_title);
        title.setText("第" + position + "张title");

        Glide.with(MainActivity.this)
                .load(banner.getUrl())
                .error(R.mipmap.ic_launcher)
                .into((ImageView) bannerView.findViewById(R.id.banner_img));
