1.問題場景

由于系統(tǒng)自帶的Latin輸入法不支持遙控器操作，需要替換為RK的拼音輸入法。

2. 替換步驟

1）將LatinIME從mk中刪除，讓系統(tǒng)編譯的時(shí)候不編譯該apk

2）添加PinyinIME的編譯預(yù)裝

3）設(shè)置PinyinIME為默認(rèn)輸入法。這一步在網(wǎng)上搜了幾個(gè)方案 ，但是都有些問題，后面自己試驗(yàn)用如下方式可以設(shè)置成功，即在InputManagerServices.java的buildInputMethodListLocked函數(shù)中添加設(shè)置默認(rèn)輸入法值的動(dòng)作
