给 RecyclerView 加上四周圆角,也适用于对话框中使用一个圆角 RecyclerView
在Canvas画之前加上
c.setDrawFilter(new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG|Paint.FILTER_BITMAP_FLAG));
即可
例如
@Override
public void onDraw(Canvas c, RecyclerView parent, RecyclerView.State state) {
c.setDrawFilter(new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG|Paint.FILTER_BITMAP_FLAG));
c.clipRect(rectF);
c.clipPath(path, Region.Op.REPLACE);
}
android10上崩溃
用28的RecyclerView可以直接设置 background 实现
如果RecyclerView的item是个全屏的ImageView圆角展示不出来
recyclerView.getViewTreeObserver().addOnGlobalLayoutListener(...)
这样子还是改变的rv本身; 只是把这个监听移到 itemDecoration中了; 跟直接设置rv的 监听没区别啊...
不论怎样,改变的只能是background; 总是会被实际内容遮住的;还是要配合padding之类的操作才好
