Common Methods:

Void adjustStreamVolume (int streamType, int direction, int flags)

Adjust the voice of the specified type on the phone. The first parameter streamType specifies the sound type. This parameter can be set to the following values.

L int STREAM_ALARM: the sound of an alarm on the phone.

L int STREAM_DTMF: DTMF tone.

L int STREAM_MUSIC: the voice of mobile phone music.

L int STREAM_NOTIFICATION: The sound prompted by the system.

L int STREAM_RING The: The sound of The phone ringtone.

L int STREAM_SYSTEM: the voice of the mobile phone system.

L int STREAM_VOICE_CALL: Voice call.

The second parameter specifies whether to increase or decrease the sound. This parameter can be set to the following values:

ADJUST_LOWER volume reduction

ADJUST_RAISE increases the volume

ADJUST_SAME remains unchanged, which is mainly used to show the current volume to the user

The third parameter is the identifier when the sound is adjusted. For example, if FLAG_SHOW_UI is specified, the volume progress bar is displayed when the sound is adjusted.

Void setMicrophoneMute (booleanon)

Set whether to mute the microphone. Set to true to mute the microphone; false to disable mute.

Void setMode (intmode)

Set the sound mode. Configurable values include NORMAL, RINGTONE, and IN_CALL.

Void setRingerMode (intringerMode)

Set the phone ringtone mode. The following attribute values are supported.

L int RINGER_MODE_NORMAL: A normal ringtone.

L int RINGER_MODE_SILENT: mute the ringtone.

L int RINGER_MODE_VIBRATE: the mobile phone vibrates.

Void setSpeakerphoneOn (booleanon)

Set the speaker to turn on or off. Set to true to enable hands-free calls; false to disable hands-free calls.

Void setStreamMute (intstreamType, booleanstate)

Set the voice of the specified type to mute. The streamType parameter has the same meaning as the first parameter in the adjustStreamVolume method.

Void setStreamVolume (int streamType, int index, int flags)

Directly set the volume of the specified type of mobile phone. The streamType parameter has the same meaning as the first parameter in the adjustStreamVolume method.
