ViewPagerDemo

使用viewpager实现轮播图效果

How to To get a Git project into your build:

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

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

Step 2. Add the dependency

dependencies {
        implementation 'com.github.kuang2010:ViewPagerDemo:1.0.0'
}

Step 3. partial code in layout xml file

<com.kuang2010.bannerview.Bannerview
    android:id="@+id/banner_view"
    android:layout_width="match_parent"
    android:layout_height="200dp"/>

<com.kuang2010.bannerview.PointIndicatorView
    android:id="@+id/pv_main"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    app:pointRadius = "5dp"
    app:pointNormalColor = "#999999"
    app:pointSelectColor = "#f00000"
    app:pointSpace = "5dp"
    android:layout_marginTop="15dp"/>

Step 4. partial code in Activity file

      mBanner_view.initDatasAndItem(datas,new BannerAdapter.OnSetItemViewListener() {
        @Override
        public View instantiateItem(int position, Object data) {

            ImageView imageView = new ImageView(MainActivity.this);

            imageView.setScaleType(ImageView.ScaleType.FIT_XY);

            imageView.setImageResource((Integer) data);

            return imageView;
        }
    });

    mBanner_view.setIndicator(pv_main);

int screenWidth = getScreenWidth(this);
    mBanner_view.setMarginAndAspectRatio((int)(60 / 1080f * screenWidth), (int)(24 / 1080f * screenWidth),960/492f);
