一.介绍

在应用层监听通话状态只有三种，从TelephonyManager.java中注释可知这三种状态含义如下：    CALL_STATE_IDLE 空闲态(没有通话活动)    CALL_STATE_RINGING 包括响铃、第三方来电等待    CALL_STATE_OFFHOOK 包括dialing拨号中、active接通、hold挂起等由上可知，active接通状态没有单独给出，所以我们无法得知电话是否接通了，因此需要其它手段来获取更多的精确通话状态，遍查网络资料，一般有两种方法！

public class TelephonyManager {    /** Device call state: No activity. */    public static final int CALL_STATE_IDLE = 0;    /** Device call state: Ringing. A new call arrived and is     *  ringing or waiting. In the latter case, another call is     *  already active. */    public static final int CALL_STATE_RINGING = 1;    /** Device call state: Off-hook. At least one call exists      * that is dialing, active, or on hold, and no calls are ringing      * or waiting. */    public static final int CALL_STATE_OFFHOOK = 2;}

二.监听9种通话状态

法一.使用系统api监听

条件: 1.需要权限android.permission.READ_PRECISE_PHONE_STATE、app打包时需要系统签名、安装在系统目录等 2.onPreciseCallStateChanged 精确通话回调api在android.jar中被hide了, 可以使用反射或没有被hide的android.jar解决

TelephonyManager telM = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);telM.listen(new PhoneStateListener(){        /**         * 当有精确通话状态时回调         * Callback invoked when precise device call state changes         * @hide 隐藏api,给系统app使用的         */        @Override        public void onPreciseCallStateChanged(PreciseCallState callState) {            //当有精确通话状态时回调        }    }, PhoneStateListener.LISTEN_PRECISE_CALL_STATE); //需要权限android.permission.READ_PRECISE_PHONE_STATE// 精确的九大通话状态public class PreciseCallState implements Parcelable {    public static final int PRECISE_CALL_STATE_IDLE =           0; //通话空闲    public static final int PRECISE_CALL_STATE_ACTIVE =         1; //正在通话(活动中)    public static final int PRECISE_CALL_STATE_HOLDING =        2; //通话挂起(例如我和多个人通话,其中一个通话在活动,而其它通话就会进入挂起状态)    public static final int PRECISE_CALL_STATE_DIALING =        3; //拨号开始    public static final int PRECISE_CALL_STATE_ALERTING =       4; //正在呼出(提醒对方接电话)    public static final int PRECISE_CALL_STATE_INCOMING =       5; //对方来电    public static final int PRECISE_CALL_STATE_WAITING =        6; //第三方来电等待(例如我正在和某人通话,而其他人打入时就会就进入等待状态)    public static final int PRECISE_CALL_STATE_DISCONNECTED =   7; //挂断完成    public static final int PRECISE_CALL_STATE_DISCONNECTING =  8; //正在挂断}

法二.读取Logcat通信日志

条件: 1.android 4.1以上需要root权限，android 4.1以下版本只需添加日志权限android.permission.READ_LOGS2.读取通信状态：在root状态下执行命令 logcat -v time -b radiologcat日志被划分为以下几个缓冲区    -b <system, radio, events, main>    main   — 主日志缓冲区(默认,普通app应用)    radio  — 无线/电话相关日志缓冲区　　　    events — 事件相关日志缓冲区    system — 系统相关日志缓冲区

//正则表达式，匹配通话状态Pattern ptn = Pattern.compile("(\\d{2}\\-\\d{2}\\s\\d{2}\\:\\d{2}\\:\\d{2}\\.\\d{3}).*?GET_CURRENT_CALLS.*?,(\\w+),");//Pattern ptn = Pattern.compile("(\\d{2}-\\d{2}\\s\\d{2}:\\d{2}:\\d{2}\\.\\d{3}).*?qcril_qmi_voice_all_call_status_ind_hdlr:.call.state.(\\d),");//使用Root权限，执行logcat命令Process process = Runtime.getRuntime().exec("su");PrintWriter pw = new PrintWriter(process.getOutputStream());pw.println("logcat -v time -b radio"); //logcat命令, -v 详细时间; -b radio 通信相关日志缓冲区pw.flush();//循环读取通话日志BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));String strLine;while ((strLine = br.readLine()) != null) {         Matcher matcher = ptn.matcher(strLine);    if (matcher.find()) {// 匹配结果            String time = matcher.group(1);  //提取通话时间        String state = matcher.group(2); //提取通话状态    }}pw.close();br.close();process.destroy();
