#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

####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:1.1.8@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;
    }
}

###The Most Complex in layout xml

<com.flyco.bannersamples.banner.SimpleImageBanner
        android:id="@+id/sib_the_most_comlex_usage"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        banner:bb_barColor="#88000000"
        banner:bb_barPaddingBottom="5dp"
        banner:bb_barPaddingLeft="10dp"
        banner:bb_barPaddingRight="10dp"
        banner:bb_barPaddingTop="5dp"
        banner:bb_delay="2"
        banner:bb_indicatorGravity="RIGHT"
        banner:bb_isAutoScrollEnable="true"
        banner:bb_isBarShowWhenLast="true"
        banner:bb_isIndicatorShow="true"
        banner:bb_isLoopEnable="true"
        banner:bb_isTitleShow="true"
        banner:bb_period="10"
        banner:bb_scale="0.5625"
        banner:bb_textColor="#ffffff"
        banner:bb_textSize="13.5sp"
        banner:bib_indicatorCornerRadius="3dp"
        banner:bib_indicatorGap="8dp"
        banner:bib_indicatorHeight="6dp"
        banner:bib_indicatorSelectColor="#ffffff"
        banner:bib_indicatorStyle="CORNER_RECTANGLE"
        banner:bib_indicatorUnselectColor="#88ffffff"
        banner:bib_indicatorWidth="6dp"/>

int Java Code

sib
    .setSelectAnimClass(ZoomInEnter.class)              //set indicator select anim
    .setSource(DataProvider.getList())                  //data source list
    .setTransformerClass(ZoomOutSlideTransformer.class) //set page transformer
    .startScroll();

###The Simplest in layout xml

<com.flyco.bannersamples.banner.SimpleImageBanner
       android:id="@+id/sib_simple_usage"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       banner:bb_scale="0.5625"/>

int Java Code

sib
   .setSource(DataProvider.getList())
   .startScroll();
