xamarin 可以很方便的编写一个电话拨号程序,下面的代码是调用android系统的拨号功能,拨号前会给出一个提示信息。
callButton是一个用来拨号的按钮,我们使用它的点击事件来进行拨号,拨号前会有一个提示框
callButton.Click += (object sender, EventArgs e) => { // On "Call" button click, try to dial phone number. 75271.com var callDialog = new AlertDialog.Builder(this); callDialog.SetMessage("Call " + translatedNumber + "?"); callDialog.SetNeutralButton("Call", delegate { // Create intent to dial phone var callIntent = new Intent(Intent.ActionCall); callIntent.SetData(Android.Net.Uri.Parse("tel:" + translatedNumber)); StartActivity(callIntent); }); callDialog.SetNegativeButton("Cancel", delegate { }); // Show the alert dialog to the user and wait for response. callDialog.Show(); };
