android 铃声设置

1、首先选中列表的铃声

    private void doPickRingtone() {

        Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
        // Allow user to pick 'Default'
        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, true);
        // Show only ringtones
        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_RINGTONE);
        // Don't show 'Silent'
        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_SILENT, false);

        Uri ringtoneUri;
        if (mCustomRingtone != null) {
            ringtoneUri = Uri.parse(mCustomRingtone);
        } else {
            // Otherwise pick default ringtone Uri so that something is selected.
            ringtoneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);
        }

        // Put checkmark next to the current ringtone for this contact
        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, ringtoneUri);

        // Launch!
        startActivityForResult(intent, RINGTONE_PICKED);
    }

2、选中之后修改数据库

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode != RESULT_OK) {
            return;
        }

        switch (requestCode) {
            case RINGTONE_PICKED: {
　　　　　　    // 选择完铃声之后获得选中铃音的URI,将其值存入数据库
                Uri pickedUri = data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);
 handleRingtonePicked(pickedUri);
break;
}
}
}

private void handleRingtonePicked(Uri pickedUri) {
if (pickedUri == null || RingtoneManager.isDefault(pickedUri)) {
mCustomRingtone = null;
} else {
mCustomRingtone = pickedUri.toString();
}
saveData();
}

/**
* 保存数据
*/
private void saveData() {
ContentValues values = new ContentValues();
values.put(Contacts.CUSTOM_RINGTONE, mCustomRingtone);
//这里的mContactId是当前联系人的Id
getContentResolver().update(Contacts.CONTENT_URI, values, Contacts._ID + " = " + mContactId, null) ;
}

通过程序获取android系统手机的铃声和音量。同样，设置铃声和音量的方法也很简单! 　　AudioManager mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE); 　　//通话音量 　　int max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_VOICE_CALL ); 　　int current = mAudioManager.getStreamVolume( AudioManager.STREAM_VOICE_CALL ); 　　Log.d(”VIOCE_CALL”, “max : ” + max + ” current : ” + current); 　　//系统音量 　　max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_SYSTEM ); 　　current = mAudioManager.getStreamVolume( AudioManager.STREAM_SYSTEM ); 　　Log.d(”SYSTEM”, “max : ” + max + ” current : ” + current); 　　//铃声音量 　　max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_RING ); 　　current = mAudioManager.getStreamVolume( AudioManager.STREAM_RING ); 　　Log.d(”RING”, “max : ” + max + ” current : ” + current); 　　//音乐音量 　　max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_MUSIC ); 　　current = mAudioManager.getStreamVolume( AudioManager.STREAM_MUSIC ); 　　Log.d(”MUSIC”, “max : ” + max + ” current : ” + current); 　　//提示声音音量 　　max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_ALARM ); 　　current = mAudioManager.getStreamVolume( AudioManager.STREAM_ALARM ); 　　Log.d(”ALARM”, “max : ” + max + ” current : ” + current); 　　设置音量的方法也很简单，AudioManager提供了方法： 　　public void setStreamVolume(int streamType, int index, int flags) 　　其中 streamType 有内置的常量，去文档里面就可以看到 xml中的配置需求 <RingtonePreference android:key="RingtonePreference" android:title="RingtonePreference" android:summary="选择铃声" /> 网址：http://www.myext.cn/android/21296.html http://haogood.5d6d.com/thread-893-1-1.html http://is00hcw.spaces.live.com/blog/cns!30EBEBD8BCD440DC!689.entry http://hi.baidu.com/adnroidorg/blog/item/51e5e329024508365343c185.html http://www.eoeandroid.com/thread-45220-1-1.html http://blog.163.com/guozioo@126/blog/static/6408694720106711453584/ http://www.eoeandroid.com/thread-9252-1-1.html
