你嘗試添加android.permission.WRITE_SETTINGS到你的清單嗎？ – scana

我添加了此權限，但它在API級別<= 23但在API級別中不工作> = 23 – Shailesh

我相信此問題已經得到解答： http://stackoverflow.com/questions/26402813/how-to-在編程方式啓用顯示觸摸選項在Android中 – Gellert

從API級別23您必須Requesting Permissions at Run Time。

以上，我也做，但不能工作 – Shailesh

你有請求WRITE_SETTINGS的權限。我不是在談論明確的許可，而是從用戶那裏得到你必須從棉花糖做到的許可。 – KDeogharkar

我認爲你在談論動態獲得的java文件，我也做但不工作的權限，我這樣做，如果（Build.VERSION.SDK_INT> = Build.VERSION_CODES.M）{ requestPermissions（new String [] {Manifest .permission.WRITE_SETTINGS}，1）; } – Shailesh
