Android静音/取消静音手机 [英] Android mute/unmute phone

问题描述

我的目标是支持2种操作:

My goal is to support 2 operations:

• 静音电话(可能启用/禁用了振动功能)，因此当接到电话或短信时，它不会发出声音

• mute phone (possibly with vibrations enabled/disabled), so when a call or sms is received it won't make noise

取消静音并恢复静音之前的音量

unmute phone and restore the volume to the state before muting phone

我该怎么做? AndroidManifest需要什么权限?

How can I do this? What permissions are required in AndroidManifest?

推荐答案

这是振动进入清单文件的权限

This is the permission for vibrate into the manifest file

<uses-permission android:name="android.permission.VIBRATE" />

这是为了使设备处于振动的静音模式

this is for to put the device in silent mode with vibrate

AudioManager audioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);

这是用于进入振铃模式

AudioManager audioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
int maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_RING);

audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
audioManager.setStreamVolume(AudioManager.STREAM_RING, maxVolume, AudioManager.FLAG_SHOW_UI + AudioManager.FLAG_PLAY_SOUND);
