Android4.0-4.4 添加實體按鍵震動支援的方法(java + smali版本)

有些手機比如泛泰A820L, 泛泰A890 A900 以及Nubia Z5S 和Z5S mini具有實體按鍵(這裡所說的實體按鍵是相對於虛擬按鍵而言, 包含物理按鍵和觸控螢幕上多出來的觸摸實體按鍵), 當編譯第三方ROM比如CM或者Mokee或者Omni時就會發現如果不做修改的話預設觸摸實體按鍵時是沒有震動支援的, 甚至有些patchrom的MIUI或者ColorOS等系統也可能不支援. 不知道是CM代碼的問題還是編譯的Config沒寫完全造成的, 後來經過本人修改後是可以支援按鍵震動, 不過只能作為臨時解決方案參考.

java版本代碼

在本人提交的cm的review上, 沒有被通過,因為如果加進來不修改的話,會影響虛擬鍵的震動,會導致home鍵震動兩次, 不過只是作為支援實體按鍵震動的話還是可以的:

對應的smali版本, 

在本人之前適配的泛泰A820L的cm10版本的樂蛙ROM裡可以找到, 是分幾次完成的:

上面的patch2主要是加了防止長按home鍵長振, 對應的java部分是:

+        if (down && repeatCount == 0) {+        setKeyVib(win);+        }
