you can install a chinese IME after rooting your device.
non-rooted, just a idea
:
1. flash ime(e.g. sogou ime) and sqlite3 to device.
2. do_update.sh:
Code:
if [ -f ${SYSTEM}/bin/sqlite3 ]
then
chmod 777 ${SYSTEM}/bin/sqlite3
echo "update secure set value = 'com.sohu.inputmethod.sogou/.SogouIME' where name = 'enabled_input_methods';" | ${SYSTEM}/bin/sqlite3 ${data}/data/com.android.provider.settings/databases/settings.db
echo "update secure set value = 'com.sohu.inputmethod.sogou/.SogouIME' where name = 'default_input_method';" | ${SYSTEM}/bin/sqlite3 ${data}/data/com.android.provider.settings/databases/settings.db
