you can use this code snippet to reverse your layout views.
您可以使用此代码片段来反转您的布局视图。
LinearLayout ll = // inflate
ArrayList<View> views = new ArrayList<View>();
for(int x = 0; x < ll.getChildCount(); x++) {
views.add(ll.getChildAt(x));
}
ll.removeAllViews();
for(int x = views.size() - 1; x >= 0; x--) {
ll.addView(views.get(x));
}
OR To begin supporting RTL layouts in your app, set the android:supportsRtl attribute to the element in your manifest file and set it “true". Once you enable this, the system will enable various RTL APIs to display your app with RTL layouts. For instance, the action bar will show the icon and title on the right side and action buttons on the left, and any layouts you've created with the framework-provided View classes will also be reversed. Look at this android doc
或 要开始在您的应用中支持 RTL 布局，请将 android:supportsRtl 属性设置为清单文件中的元素并将其设置为“true”。启用此功能后，系统将启用各种 RTL API 以显示具有 RTL 布局的应用。例如，操作栏将在右侧显示图标和标题，在左侧显示操作按钮，并且您使用框架提供的 View 类创建的任何布局也将被反转。 看这个 android doc

You can set on the parent view element's gravity to right
您可以将父视图元素的重力设置为右侧
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" <!-- make sure this is not wrap_content !-->
android:layout_height="match_parent"
android:orientation="horizontal"
android:gravity="right" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="A"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="B"/>
</LinearLayout
