Monitor the volume of ringtones in the Android system (ringtones, volumes, mute, and speakers)

The Android program obtains and sets the ringtone and volume.
Obtain the ringtones and volume of the android mobile phone through a program. Similarly, you can set the ringtone and volume easily!

AudioManagermAudioManager = (AudioManager) getSystemService (Context. AUDIO_SERVICE );
// Call volume

Int max = mAudioManager. getStreamMaxVolume (AudioManager. STREAM_VOICE_CALL );
Int current = mAudioManager. getStreamVolume (AudioManager. STREAM_VOICE_CALL );
Log. d ("VIOCE_CALL", "max:" + max + "current:" + current );
// System volume

Max = mAudioManager. getStreamMaxVolume (AudioManager. STREAM_SYSTEM );
Current = mAudioManager. getStreamVolume (AudioManager. STREAM_SYSTEM );
Log. d ("SYSTEM", "max:" + max + "current:" + current );
// Ringtone volume

Max = mAudioManager. getStreamMaxVolume (AudioManager. STREAM_RING );
Current = mAudioManager. getStreamVolume (AudioManager. STREAM_RING );
Log. d ("RING", "max:" + max + "current:" + current );
// Music volume

Max = mAudioManager. getStreamMaxVolume (AudioManager. STREAM_MUSIC );
Current = mAudioManager. getStreamVolume (AudioManager. STREAM_MUSIC );
Log. d ("MUSIC", "max:" + max + "current:" + current );
// Sound volume prompt

The method for setting the volume is also very simple. AudioManager provides the method:
Public void setStreamVolume (int streamType, int index, int flags)

StreamType is the ringtone type, such as AudioManager. STREAM_VOICE_CALL and AudioManager. STREAM_SYSTEM. The index is the volume size.

Falgs is the flag.

Set Vibration:
MVibrator = (Vibrator) mContext. getSystemService (Service. VIBRATOR_SERVICE );
Long [] pattern = {150,100}; // OFF/ON/OFF/ON...
MVibrator. vibrate (pattern,-1 );

Mute:
Set the system sound to 0.

// Set mute during a call

System. out. println ("isMicrophoneMute =" + audioManager. isMicrophoneMute ());
AudioManager. setMicrophoneMute (! AudioManager. isMicrophoneMute ());

// Set hands-free during calls

System. out. println ("isSpeakerphoneOn =" + audioManager. isSpeakerphoneOn ());
AudioManager. setSpeakerphoneOn (! AudioManager. isSpeakerphoneOn ());

// Do not forget the modified permissions.

Max = mAudioManager. getStreamMaxVolume (AudioManager. STREAM_ALARM );
Current = mAudioManager. getStreamVolume (AudioManager. STREAM_ALARM );
Log. d ("ALARM", "max:" + max + "current:" + current );
