您可以在清单中注册一个 BroadcastReceiver 来侦听android.provider.Telephony.SECRET_CODE意图。您还可以在清单中指定密码。

例如，这个清单条目注册MyBroadcastReceiver了密码*#*#12345#*#*。

<receiver android:name="MyBroadcastReceiver">
    <intent-filter>
        <action android:name="android.provider.Telephony.SECRET_CODE"/>
        <data android:scheme="android_secret_code" android:host="12345"/>
    </intent-filter>
</receiver>

MyBroadcastReceiver应该是这样的：

public class MyBroadcastReceiver extends BroadcastReceiver {
    public void onReceive(Context context, Intent intent) {
        // Create an intent to start your Service.
    }
}
