为什么我只在模拟器上收到错误？
答案 0 :(得分：3)
<Space
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/boton1"
android:layout_marginRight="22dp"
android:layout_marginTop="65dp"
android:layout_toLeftOf="@+id/imageView2" />
由于space。它是在Android 14中引入的，可能你的模拟器有一个旧版本（早于14）。由于目的是在通用布局中创建组件之间的间隙，我认为您可以使用
<View
android:layout_width="2dip"
android:layout_height="wrap_content"
android:layout_below="@+id/boton1"
android:layout_marginRight="22dp"
android:layout_marginTop="65dp"
