当PagerAdapter.getPageWidth()<1f时,使所有ViewPager项目居中对齐

Question

问题描述:当PagerAdapter.getPageWidth()<1f时,该项目显示在左侧.

我的问题我希望项目位于中心或右侧.因此,当向左或向右滚动时,所有项目将是居中对齐.(ViewPager width =页面宽度+ 2*pageMargin)

Answer 1

你可以在drawChild方法中翻译Canvas，比如

@Override
protected boolean drawChild(Canvas canvas, View child, long drawingTime) {
    canvas.save();
    canvas.translate(distance, 0);  // change any distance value you want
    boolean r = super.drawChild(canvas, child, drawingTime);
    canvas.restore();
    return r;
}
