问题描述

我在USSD号码使用此调用

I am calling on USSD number using this

字符串USSD code =*+123+ Uri.en code（＃）;

String ussdCode = "*" + "123" + Uri.encode("#");

推荐答案

这是不是我的解决方案。它是从这里。如果你知道俄罗斯你可以阅读整篇文章出现。不过这里是他们的孤子：

This is not my solution. It is taken from here. If you know Russian you can read the whole article there. However here is their solition:

import com.example.android.UssdMessage.USSD;



public class UssdmessageActivity extends Activity implements OnClickListener {
        /** Called when the activity is first created. */
        private TextView view;
        private AutoCompleteTextView number;

        @Override
        public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.main);
                Button button = (Button) findViewById(R.id.button1);
                button.setOnClickListener(this);
                this.view = (TextView) findViewById(R.id.Text2);
                this.number = (AutoCompleteTextView) findViewById(R.id.Text1);
        }

        @Override
        public void onClick(View arg0) {
                String encodedHash = Uri.encode("#");
                call("*" + number.getText() + encodedHash);
                this.view.setText("");
        }

        protected void call(String phoneNumber) {
                try {
                        startActivityForResult(
                                        new Intent("android.intent.action.CALL", Uri.parse("tel:"
                                                        + phoneNumber)), 1);
                } catch (Exception eExcept) {
                        this.view.append("\n\n " + "\n" + eExcept.toString());
                }
        }

        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
                USSD ussd = new USSD(4000,4000); // передается два параметра, задержка до и после (ms) создания сообщения
                if (ussd.IsFound())
                        this.view.append("\n"+ussd.getMsg());
                else
                        this.view.append(""+R.string.error_ussd_msg);
        }
}

他们依靠此类以USSD解析。

执行这项活动后，您可以清除与USSD消息TextView的。或者，你可以完成一个活动。

After implementing this activity you can clear the TextView with the ussd message. Or you can finish an activity.
