如何确定在一个独立的应用程序的电流呼叫者的电话号码 [英] How to determine the phone number of a current caller in a stand-alone application

问题描述

我想建立一个Android应用程序，可以通过pre-确定短信联系当前调用者。发送文本消息是很简单的，但在确定一个独立的应用程序的当前呼叫方的电话号码是一个挑战。是有一个简单的方法就可以洞察到的电话号码，所以我仍然可以给他们发送消息，而在电话吗？

当然，也有手工的方式来做到这一点：记下数目，钥匙插入一个新的文本信息，输入信息。但我想定义消息了前面，能够将其发送给当前调用者。

解决方案

  @覆盖
公共无效的onReceive（上下文的背景下，意图意图）{

    TelephonyManager电话=（TelephonyManager）context.getSystemService（Context.TELEPHONY_SERVICE）;
    PhoneCallStateListener customPhoneListener =新PhoneCallStateListener（上下文）;
    telephony.listen（customPhoneListener，PhoneStateListener.LISTEN_CALL_STATE）;
    辅助=新ContactDatabaseHelper（上下文）;
    表= helper.getAllContacts（）;

    尝试{
        incomingNumber = intent.getStringExtra（TelephonyManager.EXTRA_INCOMING_NUMBER）;

        如果（则为list.size（）！= 0）{
            的for（int i = 0，大小=则为list.size（）; I＆LT;大小;我++）{
                如果（PhoneNumberUtils.compare（incomingNumber，list.get（ⅰ）.getContactNumber（）））{
                    ToastMsg.showToast（背景下，list.get（我）.getContactName（）+调用）;
                }

I'd like to build an Android application that can contact the current caller via a pre-determined text message. Sending a text message is simple enough but determining the phone number of the current caller in a stand-alone application is the challenge. Is the there an easy way to divine the phone number so I can send them a message while still on the call?

Of course there are manual ways to do this: write down the number, key it into a new text message, enter the message. But I want to define the message up front and be able to "send it to current caller".

解决方案

@Override
public void onReceive(Context context, Intent intent) {

    TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    PhoneCallStateListener customPhoneListener = new PhoneCallStateListener(context);
    telephony.listen(customPhoneListener, PhoneStateListener.LISTEN_CALL_STATE);
    helper = new ContactDatabaseHelper(context);
    list = helper.getAllContacts();

    try{
        incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);

        if (list.size() != 0){
            for ( int i  = 0, size = list.size(); i < size; i++ ){
                if (PhoneNumberUtils.compare(incomingNumber, list.get(i).getContactNumber())){                  
                    ToastMsg.showToast(context,list.get(i).getContactName()+" Calling");
                }
            }
        }


    }catch (Exception e) {
        // TODO: handle exception
    }   

}


public class PhoneCallStateListener extends PhoneStateListener{
private Context context;

public PhoneCallStateListener(Context context){
    this.context = context;
}

@Override
public void onCallStateChanged(int state, String incomingNumber) {  

    switch (state) {

        case TelephonyManager.CALL_STATE_RINGING:       


            break;
        case PhoneStateListener.LISTEN_CALL_STATE:

    }
    super.onCallStateChanged(state, incomingNumber);
}
}
