Android：如何对齐交换机＆＃39;正确的界限？

Question

我有一些垂直列出的开关。但我不知道如何调整它们。我可以使用约束在一台设备上手动对齐右边界，但是当我更换设备时，它们不会再次对齐。

===================更改设备后下面的结果不好===============

那么我怎样才能将第一张图像作为我使用的设备实现？

You would better use below properties for supporting better alignments in any device

        android:layout_alignStart="@id/aboveItem"
        android:layout_below="@id/aboveItem"

Example:
@+id/dispcount is already having absolute position which is First Item.
<Button
        android:id="@+id/btnstart"
        android:layout_width="wrap_content"
        android:layout_height="50dp"
        android:text="@string/btnStart"
        android:visibility="visible"
        android:layout_below="@id/dispcount"
        android:layout_alignStart="@id/dispcount"
        />
    <Button
        android:id="@+id/stop"
        android:layout_width="wrap_content"
        android:layout_height="50dp"
        android:text="@string/btnStop"
        android:visibility="visible"
        android:layout_below="@id/btnstart"
        android:layout_alignStart="@id/btnstart"
         />


Above Example display vertically same alignment. Here example type is button, in your case its switch. xml attributes applies same for all alignments. take your own width & height.

通过添加类似于您的xml文件，它将自动调整所有设备。
