ConstraintLayout布局下让TextView自适应布

有时候在做页面的时候，会碰到这种情况，昵称这个TextView需要适配文字的长度，且昵称后面带有一些图片标识(比如vip等级)，如果昵称文字超过一定长度之后，将会阶段并以...结尾，此时就可以通过ConstraintLayout布局相关的属性实现该页面：
其中用到的属性为：
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintHorizontal_chainStyle="packed"
app:layout_constraintVertical_chainStyle="spread"
app:layout_constraintWidth_default="wrap"//主要是该属性标记TextView的内容自适应
