bias的使用
这个不一定在中间可以改变力的大小
<TextView android:layout_width="100dp" android:layout_height="50dp" android:background="@color/purple_700" android:gravity="center" android:text="center" android:textColor="@color/white" android:textSize="24dp" app:layout_constraintBottom_toTopOf="@+id/guideline3" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintHorizontal_bias="0.2" app:layout_constraintStart_toStartOf="@+id/guideline2" app:layout_constraintTop_toTopOf="parent" />
app:layout_constraintHorizontal_bias="0.2"
这个可以改变力的大小,y轴方向同理
Group统一控制控件,比如可不可见
