 默认在android M版本铃声设置对话框里面包含“更多铃声”选项。在N版本也包含这项，只是未让它显示。铃声

设置对话框代码在packages/providers/MediaProvider/src/com/android/providers/media/RingtonePickerActivity.java。

onCreate函数

 

 /// M: Get whether to show the 'More Ringtones' item
 mHasMoreRingtonesItem = intent.getBooleanExtra(
     RingtoneManager.EXTRA_RINGTONE_SHOW_MORE_RINGTONES, false);

 

 启动RingtonePickerActivity的时候把RingtoneManager.EXTRA_RINGTONE_SHOW_MORE_RINGTONES

设置成true。在/packages/apps/Settings/src/com/android/settings/RingtonePreference.java文件的
