有谁知道 Android 中的默认拨号器应用程序是否返回任何可以在 onActivityResult() 函数中读取的数据?像这样的东西
//Button click:
startActivityforResult(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + number)), 0);
//OnActivityResult
if(resultCode == CALL_NOT_ANSWERED)
//do sth like try again
if(resultCode == VOICEMAIL_STARTED)
//bad luck
if(resultCode == CALL_ANSWERED)
//nice one
谢谢
