#FlycoBanner-Master
A powerful android view looper library animing to simplify this high frequency function in daily development. Support for Android 2.2 and up.
#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

}##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;
}
