安卓设置中有UI touch的提示音,在按下物理按键的时候也会出现。
设置和获取的方法:
//设置 0-关闭,1-打开
Settings.System.putInt(getContentResolver(), Settings.System.SOUND_EFFECTS_ENABLED, 0);
//获取
int enabled = Settings.System.getInt(getContentResolver(), Settings.System.SOUND_EFFECTS_ENABLED);
播放代码位于framework/base/media/java/android/media/AudioManager.java
public void playSoundEffect(int effectType) {
if (effectType < 0 || effectType >= NUM_SOUND_EFFECTS) {
return;
}
if (!querySoundEffectsEnabled()) {
return;
}
IAudioService service = getService();
try {
service.playSoundEffect(effectType);
} catch (RemoteException e) {
Log.e(TAG, "Dead object in playSoundEffect"+e);
}
}
