This question already has an answer here:
I'm on an Android 4.4.2 device but solutions for PCs and Macs will be welcome too. I am using the default Samsung keyboard on the Samsung Galaxy SIII Neo.
When I entrer the characters "shu" I get 书 and another bunch of entries. I want my keyboard to allow me to filter some of these out by tone. Fshor example, by entering "shu3", where 3 indicates the fourth, falling tone, the keyboard, as i am asking for this feature, would display only the characters corresponding to pinyin "shù" and omit shū, shú, shû). So then by typing shu4 I only need scroll less and select 术.
Is there a keyboard out there which provides the improved pinyin method I describe?
