In Android: Android4.2, four new parameters appear in the RelativeLayout view, such as layout_alignStart,

Why is layout_alignStart better than layout_alignRight and layout_toLeftOf?

The new parameters are mainly used to adapt to the reading habits from right to left. For example, when you want to adapt to Arabic, start indicates the right, and Chinese indicates the left.
That is to say
When I use start to set it, if the Chinese language is displayed, this start indicates the left side; if the Arabic language is displayed, this start indicates the right side.
