Android 静音与振动
1,设置静音和振动
静音和振动都属于来电后的动作.所以在设置静音和振动时都只是设置一些标识,并往数据库写入相应标识.
文件：packages/apps/settings/src/com/android/settings/SoundAndDisplaySettings.java
[java]
<SPAN style="COLOR: #993300">private CheckBoxPreference mSilent;
private CheckBoxPreference mVibrate;
private void setRingerMode(boolean silent, boolean vibrate) {
if (silent) {
mAudioManager.setRingerMode(vibrate ? AudioManager.RINGER_MODE_VIBRATE :
AudioManager.RINGER_MODE_SILENT);
} else {
mAudioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
mAudioManager.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER,
vibrate ? AudioManager.VIBRATE_SETTING_ON
: AudioManager.VIBRATE_SETTING_OFF);
}
}
public boolean onPreferenceTreeClick(PreferenceScreen preferenceScreen, Preference preference) {
if (preference == mSilent || preference == mVibrate) {
setRingerMode(mSilent.isChecked(), mVibrate.isChecked());
if (preference == mSilent) updateState(false);
}</SPAN>
private CheckBoxPreference mSilent;
private CheckBoxPreference mVibrate;
private void setRingerMode(boolean silent, boolean vibrate) {
if (silent) {
mAudioManager.setRingerMode(vibrate ? AudioManager.RINGER_MODE_VIBRATE :
AudioManager.RINGER_MODE_SILENT);
} else {
mAudioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
mAudioManager.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER,
vibrate ? AudioManager.VIBRATE_SETTING_ON
: AudioManager.VIBRATE_SETTING_OFF);
}
}
public boolean onPreferenceTreeClick(PreferenceScreen preferenceScreen, Preference preference) {
if (preference == mSilent || preference == mVibrate) {
setRingerMode(mSilent.isChecked(), mVibrate.isChecked());
if (preference == mSilent) updateState(false);
}
静音和振动是复选框按钮,两个中有一个发生变化时调用setRingerMode对状态进行设置;如下状态描术:
RINGER_MODE_SILENT 静音,且无振动
RINGER_MODE_VIBRATE 静音,但有振动
RINGER_MODE_NORMAL 正常声音,振动开关由setVibrateSetting决定.
铃响模式的设置是通过mAudioManager(音频管理器)来实现的.
2 音频管理器服务
mAudioManager所在服务如下:
文件: frameworks/base/media/java/android/media/AudioManager.java
[java]
<SPAN style="COLOR: #993300"> public static final int RINGER_MODE_SILENT = 0;
public static final int RINGER_MODE_VIBRATE = 1;
public static final int RINGER_MODE_NORMAL = 2;
public void setRingerMode(int ringerMode) {
IAudioService service = getService();
try {
service.setRingerMode(ringerMode);
} catch (RemoteException e) {
Log.e(TAG, "Dead object in setRingerMode", e);
}
}</SPAN>
public static final int RINGER_MODE_SILENT = 0;
public static final int RINGER_MODE_VIBRATE = 1;
public static final int RINGER_MODE_NORMAL = 2;
public void setRingerMode(int ringerMode) {
IAudioService service = getService();
try {
service.setRingerMode(ringerMode);
} catch (RemoteException e) {
Log.e(TAG, "Dead object in setRingerMode", e);
}
}
将铃响模式值传给音频接口服务IaudioService[java] view plaincopyprint?
<SPAN style="COLOR: #993300">public static final int VIBRATE_TYPE_RINGER = 0;
public static final int VIBRATE_TYPE_NOTIFICATION = 1;
public static final int VIBRATE_SETTING_OFF = 0;
public static final int VIBRATE_SETTING_ON = 1;
public static final int VIBRATE_SETTING_ONLY_SILENT = 2;
public void setVibrateSetting(int vibrateTyp , int vibrateSetting) {
IAudioService service = getService();
try {
service.setVibrateSetting(vibrateType, vibrateSetting);
} catch (RemoteException e) {
Log.e(TAG, "Dead object in setVibrateSetting", e);
}
}</SPAN>
public static final int VIBRATE_TYPE_RINGER = 0;
public static final int VIBRATE_TYPE_NOTIFICATION = 1;
public static final i
