特点:

  • 广告轮播图,跟FrameLayout一样简单使用
  • 基于ViewPager+FragmentPagerAdapter,滑动流畅
  • 可定制图片加载器
  • 提供一些定制接口

文档

如何使用它

gradle

先在 project的build.gradle 添加:

allprojects {
		repositories {
			...
			maven { url "https://jitpack.io" }
		}
	}

然后在module的build.gradle 添加:

dependencies {
	        compile 'com.github.LinweiJ:BannerView:0.0.1'
	}

JAVA

1.简单使用例子

  • xml
<com.lwj.widget.bannerview.BannerView
		android:id="@+id/BannerView"
		android:layout_width="match_parent"
		android:layout_height="493dp"
		android:layout_weight="1"
		android:background="#cdcdcd"
	>
	 <TextView
		 android:id="@+id/tv_hint"
	     android:layout_width="match_parent"
	     android:layout_height="wrap_content"
         android:layout_gravity="bottom"
         android:text="提示"
     />
</com.lwj.widget.bannerview.BannerView>
  • java
 		mTv_hint = (TextView) findViewById(R.id.tv_hint);
        mBannerView = (BannerView) findViewById(R.id.BannerView);
        mBannerView.setFragmentManager(getSupportFragmentManager());
        mBannerView.setPictureUrl(mUrlList);
        mBannerView.setCircle(true);
        mBannerView.setDurationFavor(4.0f);
        mBannerView.setInitItem(0);
        mBannerView.setInterpolatorType(BannerInterpolator.ACCELERATE_DECELERATE);
        mBannerView.setPictureLoader(new BannerPictureLoader() {
            @Override
            public void showPicture(Fragment fragment, ImageView pictureView, String pictureUrl) {
                Glide.with(fragment)
                        .load(pictureUrl)
                        .into(pictureView);
            }
        });
        mBannerView.setPictureClickListener(new OnBannerPictureClickListener() {
            @Override
            public void onPictureClick(Fragment fragment, int position, List<String> pictureUrl) {
                ToastUtil.showToast(WBannerActivity.this,"position:"+position+"pictureUrl"+pictureUrl.get(position));
            }
        });
        mBannerView.setOnBannerPageSelectedListener(new OnBannerPageSelectedListener() {
            @Override
            public void onPageSelected(int position, String url) {
                mTv_hint.setText("position"+position+"\n"+url);
            }
        });
        mBannerView.start();
        
 	@Override
    protected void onStart() {
        super.onStart();
        mBannerView.startAutoPlay();
    }

    @Override
    protected void onStop() {
        super.onStop();
        mBannerView.stopAutoPlay();
    }

setCircle(boolean isCircle) 是否轮播 可选
setDurationFavor(float durationFavor) 滑动动画时长因子，默认1.0F，值越大时间越长 可选
setInterpolatorType(int type) 滑动动画变化速度类型,见BannerInterpolator[1] 可选
setInitItem(int position ) 初始页，默认0 可选
initPictureLoader(BannerPictureLoader loader) 初始化图片加载器(只初始化一次),见BannerPictureLoader[2] 与setPictureLoader,必须二选一
setPictureLoader(BannerPictureLoader loader) 设置图片加载器,见BannerPictureLoader[2] 与initPictureLoader ,必须二选一
setPictureClickListener(OnBannerPictureClickListener listener) 设置图片点击事件,见OnBannerPictureClickListener[3] 可选
addOnPageChangeListener(ViewPager.OnPageChangeListener listener) ViewPager 滑动监听事件 可选
setOnBannerPageSelectedListener(OnBannerPageSelectedListener listener) ViewPager 页面选中事件,见OnBannerPageSelectedListener[4] 可选
start() 配置完成后调用 必须
startAutoPlay() 设置setCircle(ture)有效,通常在start()调用,开始轮播, 可选
stopAutoPlay() 设置setCircle(ture)有效,通常在stop()调用,停止轮播 可选
getViewPager() 获取ViewPager 可选
  • BannerInterpolator[1]
常量 描述
LINEAR 直线
ACCELERATE 在动画开始的地方速率改变比较慢，然后开始加速
DECELERATE 在动画开始的地方快然后慢
ACCELERATE_DECELERATE 在动画开始与介绍的地方速率改变比较慢，在中间的时候加速
  • BannerPictureLoader[2]
方法 描述 备注
showPicture(Fragment fragment, ImageView pictureView, String pictureUrl) 自定义图片加载方式 可选Glide等图片加载库
  • OnBannerPictureClickListener[3]
方法 描述 备注
onPictureClick(Fragment fragment, int position, List pictureUrl) BannerView图片点击事件,参数pictureUrl:图片列表,position:当前点击图片index
  • OnBannerPageSelectedListener[4]
