一個強大的android view looper 庫，以簡化日常開發這種高頻率的功能。支持安卓2.2及更高版本。

Background

Image loop banner is high frequency used in most apps. So is the app of the company I work for. At first, this is only used in home page. Later with the app update, there are some simliar functions needed in other pages both image and text. I copy the same code here and there, finally I can not standing copying anymore. I explore on the github to find libs that meet my needs. Though I find some poewful libs, but the lib what I want should support view looping not only ImageView. And I do not want a lib having a ImageLoad Framework inside. So I decide to code a libray with features below:

• Use Executors instead of Task
• Supports both normal banner and endless auto loop banner
• Supports inflate item view and logic operation such as loading image outside.
• Supports set source using data list with different entity
• Supports smartly pause scroll and continue scroll.
  • Touch down pause. Touch up continue.
  • Window of activty off pause.Window of activty on continue.
• Supports inner indictaors
• Supports page transformer (not often used in my daily work, just support this feature for others if needed)

Demo

Here is a DemoApk download

Gradle

dependencies{
    compile 'com.android.support:support-v4:22.2.1'
    compile 'com.nineoldandroids:library:2.4.0'
    compile 'com.flyco.banner:FlycoBanner_Lib:1.0.1@aar'
}

Usage

Extends BaseIndicaorBanner and Set Data Type

public class SimpleImageBanner extends BaseIndicaorBanner<BannerItem, SimpleImageBanner> {
    private ColorDrawable colorDrawable;

    public SimpleImageBanner(Context context) {
        this(context, null, 0);
    }

    public SimpleImageBanner(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public SimpleImageBanner(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        colorDrawable = new ColorDrawable(Color.parseColor("#555555"));
    }

    @Override
    public void onTitleSlect(TextView tv, int position) {
        final BannerItem item = list.get(position);
        tv.setText(item.title);
    }

    @Override
    public View onCreateItemView(int position) {
        View inflate = View.inflate(context, R.layout.adapter_simple_image, null);
        ImageView iv = ViewFindUtils.find(inflate, R.id.iv);

        final BannerItem item = list.get(position);
        int itemWidth = dm.widthPixels;
        int itemHeight = (int) (itemWidth * 360 * 1.0f / 640);
        iv.setScaleType(ImageView.ScaleType.CENTER_CROP);
        iv.setLayoutParams(new LinearLayout.LayoutParams(itemWidth, itemHeight));

        String imgUrl = item.imgUrl;

        if (!TextUtils.isEmpty(imgUrl)) {
            Glide.with(context)
                    .load(imgUrl)
                    .override(itemWidth, itemHeight)
                    .centerCrop()
                    .placeholder(colorDrawable)
                    .into(iv);
        } else {
            iv.setImageDrawable(colorDrawable);
        }

        return inflate;
    }
}
