感觉两张图片间距太小，怎么设置的大些

访问网络图片时，会把图片地址展示出来

我是加载的网络图片，一共五个图片，首次进入默认竟然显示的是第4张图片，指示器又是指示第一个；滑动到第一张时下标显示的是3

1、attrs中配置是否支持缩放isScale.
2、public class BannerTransformer implements ViewPager.PageTransformer {
private static final float MAX_SCALE = 1.1f;
private static final float MIN_SCALE = 0.9f;

@OverRide
public void transformPage(View page, float position) {
if (position < -1) {//(-Infinity,-1)
page.setScaleX(MIN_SCALE);
page.setScaleY(MIN_SCALE);
} else if (position <= 0) {//[-1,0]
float scaleFactor = MIN_SCALE+(1-Math.abs(position))(MAX_SCALE-MIN_SCALE);
page.setScaleX(scaleFactor);
page.setScaleY(scaleFactor);
} else if (position <= 1) {//(0,1]
float scaleFactor = MIN_SCALE+(1-Math.abs(position))(MAX_SCALE-MIN_SCALE);
page.setScaleX(scaleFactor);
page.setScaleY(scaleFactor);
} else {//(1,Infinity)
page.setScaleX(MIN_SCALE);
page.setScaleY(MIN_SCALE);
}
}
}
3、在BannerView.java 的initAttribute()获取isScale：
mIsScale=typedArray.getBoolean(R.styleable.BannerView_isScale, mIsScale);

在initView()中设置：
if(mIsScale){
mBannerViewPager.setPageTransformer(true, new BannerTransformer());
}
