[英]How to answer a phone call programmatically Xamarin | Android
我正在使用xamarin android構建應用程序,正在實現一項功能,我想以編程方式接聽電話; 我有一個需要使用Intent
的想法,但是如何使用? 那就是我不知道的。
有人可以建議我嗎?
您可以編寫一個廣播接收器來管理您的來電:
[BroadcastReceiver]
[IntentFilter (new [] {"android.intent.action.PHONE_STATE"})]
public class IncomingPhoneCallDetector : BroadcastReceiver
{
public override void OnReceive(Context context, Intent intent)
{
if (intent.Extras != null)
{
string state = intent.GetStringExtra(TelephonyManager.ExtraState);
if (state == TelephonyManager.ExtraStateRinging)
{
string telephone = intent.GetStringExtra(TelephonyManager.ExtraIncomingNumber);
if (!string.IsNullOrEmpty (telephone))
{
Toast.MakeText (context, "Incoming call from " + telephone + ".", ToastLength.Short).Show ();
}
else
{
Toast.MakeText (context, "Incoming call from unknown number.", ToastLength.Short).Show ();
}
Intent buttonDown = new Intent(Intent.ActionMediaButton);
buttonDown.PutExtra(Intent.ExtraKeyEvent, new KeyEvent(KeyEventActions.Up, Keycode.Headsethook));
context.SendOrderedBroadcast (buttonDown, "android.permission.CALL_PRIVILEGED");
}
else if (state == TelephonyManager.ExtraStateOffhook)
{
Toast.MakeText(context, "Incoming call answered.", ToastLength.Short).Show();
}
else if (state == TelephonyManager.ExtraStateIdle)
{
Toast.MakeText(context, "Incoming call ended.", ToastLength.Short).Show();
}
}
}
}
干杯!!
