Practical Android skills: define complex strings for the right-to-left Language

The language we use, whether in Chinese or English, is read from left to right ), therefore, we are very accustomed to reading from left to right ). Once you encounter a right-to-left reading, you will be very unaccustomed to it, even more uncomfortable than seeing Mars. It is uncomfortable to look at it, but what is even more frustrating is that we need to define the Arabic language strings for the application, that is, to add the Arabic language support for the application, not only do you need to view a large number of Arabic books, but you also need to process complex strings.

For the right-to-left language, the ideal is the following two cases. It does not require special processing, as long as the translation is written into the string resource file:

1. When they are all Arabic, no special processing is required.
2. There are English/numbers on the left, but Arabic on the right (that is, there are English/numbers on the right in left-to-right)
3. If they are all English or numbers, they do not need to be processed, so that they retain the features of left-to-right.

For example:

<?xml version="1.0" encoding="utf-8"?>    <!-- file values-ar/strings.xml -->    <string name="import">استورد</string>    <string name="import_vcard">استورد vCard</string>

After running, the result is: zookeeper has been successfully executed.

VCard has been released successfully

However, in some cases, special processing is required:

1. English or numbers in the middle

If not processed, the number will be changed to right-to-left, but in fact left-to-right is required, for example:

<?xml version="1.0" encoding="utf-8"?>    <!-- file values-ar/strings.xml -->    <string name="send_msg_to">استورد%sتور</string>

After it is replaced, it will become: when there are too many attempts, then 68001 when there are too many attempts, and what is needed is: please refer to the following link for more information:

Left-to-right overrider \ u202d and \ u202c, for example:

<?xml version="1.0" encoding="utf-8"?>    <!-- file values-ar/strings.xml -->    <string name="send_msg_to">استورد\u202d%s\u202cتور</string>

1. There are English or numbers on the right (left-to-right on the left)
2. When xliff is replaced locally

The solution is to add right to left marker (rlm) before and after English or digits

<?xml version="1.0" encoding="utf-8"?>    <!-- file values-ar/strings.xml -->    <string name="send_msg_to">send استورد</string>    <string name="send_msg_to">\u200fsend استورد\u200f</string>    <string name="send_msg_to">\u200fsend <xliff:g id="number">\u200f%1$d</xliff:g>استورد</string>
