Get and set ringtones, volume, mute, and speakers in Android

 

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!

Audiomanager maudiomanager = (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

Max = maudiomanager. getstreammaxvolume (audiomanager. stream_alarm );
Current = maudiomanager. getstreamvolume (audiomanager. stream_alarm );
Log. D ("alarm", "MAX:" + MAX + "current:" + current );

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, for example, audiomanager. stream_voice_call, audiomanager. stream_system, etc. Index is the volume size falgs as 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 and set the mute system. Out. println ("ismicrophonemute =" + audiomanager. ismicrophonemute () during the call ());
Audiomanager. setmicrophonemute (! Audiomanager. ismicrophonemute (); // sets hands-free mode during calls.

System. Out. println ("isspeakerphoneon =" + audiomanager. isspeakerphoneon ());
Audiomanager. setspeakerphoneon (! Audiomanager. isspeakerphoneon (); // do not forget the modified permission <uses-Permission Android: Name = "android. Permission. modify_audio_settings"/>
