How [Android] makes the LinearLayout layout flow horizontally from right to left, not from left to right

Method 1:

<linearlayout xmlns:android= "http://schemas.android.com/apk/res/android"    android:layout_width= "Match_ Parent "    android:layout_height=" match_parent "    android:orientation=" Horizontal ">    <textview        android:layout_width= "0dip"        android:layout_height= "wrap_content"        android:layout_weight= "1"        android:text= "Hello_world"/>    <textview        android:layout_width= "wrap_content"        android:layout_ height= "Wrap_content"        android:text= "Hello_world2"/></linearlayout>

The width of the hello_world2 will squeeze the hello_world space.

Method 2: Set the LinearLayout property

Android:gravity= "Right"

Note: only layout_width= "Match_parent" in LinearLayout is valid.

   android:layout_width= "match_parent"    android:layout_height= "match_parent"    android:gravity = "Right"    android:orientation= "Horizontal" >    <textview        android:layout_width= "Wrap_content"        android:layout_height= "wrap_content"        android:text= "Hello_world"/>    <textview        android: Layout_width= "Wrap_content"        android:layout_height= "wrap_content"        android:text= "Hello_world2"/> </LinearLayout>
