问题
I tried to programmatically send DTMF tones in Android. But the emulator shows up a dialog box that says "Do you want to send these tones?" and it sends the tones only if I click OK. But how can I programmatically overcome this dialog box?
Gracias
回答1:
In my application, I am sending DTMF tones (with gap using ","). Please see the code below. If you put number as: 12345,6,7 it will dial 12345 and send 6 and 7 as dtmf tone with gap.
String url = "tel:" + number;
Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse(url));
startActivity(intent);

/**
* Dials a number with DTMF chars
* Note: When the number is dialed, only the initial number is displayed on the device dialer
* For example: dial("*6900,,1") will display only *6900 on the device dialer (but the rest will also be processed)
* @param number
*/
public void dial(String number) {
try {
number = new String(number.trim().replace(" ", "%20").replace("&", "%26")
.replace(",", "%2c").replace("(", "%28").replace(")", "%29")
.replace("!", "%21").replace("=", "%3D").replace("<", "%3C")
.replace(">", "%3E").replace("#", "%23").replace("$", "%24")
.replace("'", "%27").replace("*", "%2A").replace("-", "%2D")
.replace(".", "%2E").replace("/", "%2F").replace(":", "%3A")
.replace(";", "%3B").replace("?", "%3F").replace("@", "%40")
.replace("[", "%5B").replace("\\", "%5C").replace("]", "%5D")
.replace("_", "%5F").replace("`", "%60").replace("{", "%7B")
.replace("|", "%7C").replace("}", "%7D"));
Uri uri = Uri.parse("tel:"+ number);
Intent intent = new Intent(Intent.ACTION_CALL, uri);
startActivity(intent);
} catch (Exception e) {
//getAlertDialog().setMessage("Invalid number");
e.printStackTrace();
}
}
