[SOLUTION]
一,针对每个情景模式的默认值修改：
1,默认铃声是统一在alps/build/target/product/core.mk文件中设置，其中ro.config.notification_sound表示通知的默认铃声，ro.config.ringtone表示语音来电和视频来电的铃声，若希望语音来电和视频来电分开设置，请参考FAQ08273 [Audio Profile]如何设置视频来电铃的默认铃声:
PRODUCT_PROPERTY_OVERRIDES:=
ro.config.notification_sound=Proxima.ogg
ro.config.alarm_alert=Alarm_Classic.ogg
ro.config.ringtone=Backroad.ogg
2,情景模式中的其他设定参考到
mediatek/frameworks/base/media/audio/java/com/mediatek/audioprofile/AudioProfileManager.java
中的getDefaultState()
public static AudioProfileState getDefaultState(String profileKey) {
if (null == sDEFAULTSTATES) {
IDefaultProfileStatesGetter defaultProfileStatesGetter =
MediatekClassFactory.createInstance(IDefaultProfileStatesGetter.class);
if (defaultProfileStatesGetter != null) {
sDEFAULTSTATES = defaultProfileStatesGetter.getDefaultProfileStates();
}
if (null == sDEFAULTSTATES) {
sDEFAULTSTATES = new HashMap
