动态更改铃声有几个步骤.
准备铃声
File k = new File("/sdcard/ringtone", "kolyan_.mp3");
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, "My Song title");
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mpeg");
values.put(MediaStore.Audio.Media.ARTIST, "Some Artist");
values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
values.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
values.put(MediaStore.Audio.Media.IS_ALARM, false);
values.put(MediaStore.Audio.Media.IS_MUSIC, false);
2.将其插入数据库
Uri uri = MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath());
// Line below is major because we need to delete old entry
getContentResolver().delete(uri, MediaStore.MediaColumns.DATA + "=\"" + k.getAbsolutePath() + "\"", null);
mUri = getContentResolver().insert(uri, values);
3.保存当前的默认铃声并订阅CallListener
// Be careful by calling getActualDefaultRingtoneUri in CallListener, it could return null, better way to save it in OnCreate
mOldUri = RingtoneManager.getActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE);
TelephonyManager mTelephonyMgr = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
mTelephonyMgr.listen(new MyCallListener(), PhoneStateListener.LISTEN_CALL_STATE);
4.创建MyCallListener类
class MyCallListener extends PhoneStateListener {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_RINGING:
// On call you replace the ringtone with your own mUri
RingtoneManager.setActualDefaultRingtoneUri(
MainActivity.this,
RingtoneManager.TYPE_RINGTONE,
mUri
);
break;
case TelephonyManager.CALL_STATE_IDLE:
// Restore the default ringtone
RingtoneManager.setActualDefaultRingtoneUri(
MainActivity.this,
RingtoneManager.TYPE_RINGTONE,
mOldUri
);
break;
default:
break;
}
super.onCallStateChanged(state, incomingNumber);
}
}
5.向您安装AndroidManifest.xml的权限
完成
主要想法是挂接来电,用自己的方式取代铃声.当然,您应该在通话后将默认铃声恢复为保存的值.
