布局怎么添加个按钮？

oktongguo

这是某个软件的布局，我想在最后一个ImageView后面，添加一个按钮，不知道怎么添加。在第421行直接添加<Button
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:text="Button"/>
不起作用，可能添加的位置不对，大神看看怎么添加，在哪个位置添加？

小骚

你的顶级布局是 "ConstraintLayout" 要添加控件得使用 "layout_constraint*"来定位

要看你添加布局在哪个方向了，比如要添加在ImageView 底下 得用 "app:layout_constraintTop_toBottomOf="@+id/xxx"" 可在As里面直接拖动绑定
