Android-布局:定位按钮问题

Question

在我的app-layout中，我有一个相对布局，该布局连续包含7个按钮。现在，我想在该行开头添加另一个按钮（@ id/ib_summe）。但是在GraphicAllayout和我的设备上，前两个按钮（ @ ID/ib_summe和 @ ID/imageButton01）被覆盖。他们不是吗？我在做什么错？

我的xml-layout：

<RelativeLayout
 android:id="@+id/Buttonleiste"
 android:layout_width="fill_parent"
 android:layout_height="120px"
 android:layout_alignParentBottom="true"
 android:orientation="horizontal"

 android:paddingBottom="2dp" android:background="@drawable/gradient">

Answer 1

在您的第二个按钮中使用android:layout_toRightOf="@+id/IB_Summe"而不是android:layout_toRightOf="@id/IB_Summe"。注意加号。那应该有效
