裁剪，默认PC蛋蛋平台定制，需要请搜索【大神源码论坛】dsluntan.com 客服企娥3393756370 V信17061863513，的ImageView是矩形的，很多时候，需要的是圆角的ImageView或者圆形的ImageView，这就需要裁剪view了。
实现，裁剪圆形：
final TextView textView= findViewById(R.id.tv);
ViewOutlineProvider viewOutlineProvider=new ViewOutlineProvider() {br/>@Override
public void getOutline(View view, Outline outline) {
//设置圆形oval
outline.setOval(0,0,textView.getWidth(),textView.getHeight());
}
};
//设置裁剪
textView.setClipToOutline(true);
实现，裁剪圆角矩形：
final TextView textView= findViewById(R.id.tv);
ViewOutlineProvider viewOutlineProvider=new ViewOutlineProvider() {br/>@Override
public void getOutline(View view, Outline outline) {
//设置圆角矩形
outline.setRoundRect(0,0,view.getWidth(),view.getHeight(),25);
}
};
textView.setOutlineProvider(viewOutlineProvider);
//设置裁剪
textView.setClipToOutline(true);
