3、编写OutCallReceiver.java类

/** *  */package com.example.ipdail;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.SharedPreferences;import android.graphics.AvoidXfermode.Mode;/** * @author hyzhou * * 2013-12-5 */public class OutCallReceiver extends BroadcastReceiver {    /* (non-Javadoc)     * @see android.content.BroadcastReceiver#onReceive(android.content.Context, android.content.Intent)     */    @Override    public void onReceive(Context context, Intent intent) {        // 获得外拨电话号码        String number=getResultData();        SharedPreferences sp=context.getSharedPreferences("config",context.MODE_PRIVATE);        String ipnumber=sp.getString("number", "");                String newnumber=ipnumber+number;        setResultData(newnumber);            }}
