我一直面临着这个问题,而且一直没有能够解决以下问题:
我正在使用广播接收器来检测呼入和呼出通话的详细信息。
现在问题出在通话持续时间上。对于呼入电话,它显示的持续时间是正确的,但对于呼出电话,它却显示了错误的持续时间...
请帮助我解决这个问题。提前感谢您花费宝贵的时间帮我解决这个问题。
以下是我的代码:
public class IncomingCallReceiver extends BroadcastReceiver {
// db instance variables
DBAdapter dba;
// instance variables of sharedpreferences
SharedPreferences mSharedPrefernce;
Editor e;
// String variables for number,date,time,calltype
String number, date, time, calltype;
long startTime, endTime;
@Override
public void onReceive(Context context, Intent intent) {
Log.v("info", "calls info....");
// initialising the sharedpreferences
mSharedPrefernce = context.getSharedPreferences("MyPref", 0);
e = mSharedPrefernce.edit();
// Creating object for the DBAdapter
dba = new DBAdapter(context);
Bundle bundle = intent.getExtras();
// Log.v("info", bundle.toString());
if (bundle == null)
return;
// initialising the variables
number = null;
startTime = 0;
endTime = 0;
// getting incoming call details
String state = bundle.getString(TelephonyManager.EXTRA_STATE);
if ((state != null)
&& (state
.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))) {
Log.v("info", "Phone Ringing..");
number = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
Log.v("info", "Incomng Number: " + number);
calltype = "Incoming";
Time today = new Time(Time.getCurrentTimezone());
today.setToNow();
date = today.monthDay + "-" + (today.month + 1) + "-" + today.year;
time = today.format("%k:%M:%S");
// putting the values into the SharedPreferences
e.putString("number", number);
e.putString("Type", calltype);
e.putString("date", date);
e.putString("time", time);
e.commit();
Toast.makeText(
context,
"Detect Calls sample application\nIncoming number: "
+ number, Toast.LENGTH_SHORT).show();
}
// getting outgoing call details
else if (state == null) {
number = bundle.getString(Intent.EXTRA_PHONE_NUMBER);
Log.v("info", "Outgoing Number: " + number);
calltype = "Outgoing";
Time today = new Time(Time.getCurrentTimezone());
today.setToNow();
date = today.monthDay + "-" + (today.month + 1) + "-" + today.year;
time = today.format("%k:%M:%S");
// putting the values into the SharedPreferences
e.putString("number", number);
e.putString("Type", calltype);
e.putString("date", date);
e.putString("time", time);
e.commit();
Toast.makeText(
context,
"Detect Calls sample application\nOutgoing number: "
+ number, Toast.LENGTH_SHORT).show();
}
// called when the call is answered
else if (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
Log.v("info", "Call Ansered..");
startTime = System.currentTimeMillis();
e.putLong("start", startTime);
e.commit();
}
// called when the call is ended
else if (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_IDLE)) {
Log.v("info", "Call Ended..");
String phonenumber=null, type=null, date1=null, time1=null, duration=null;
// getting the values from the SharedPreferences
phonenumber = mSharedPrefernce.getString("number", "");
type = mSharedPrefernce.getString("Type", "");
date1 = mSharedPrefernce.getString("date", "");
time1 = mSharedPrefernce.getString("time", "");
long start=0;
start = mSharedPrefernce.getLong("start", 0);
Log.v("info", "startTime=" + start);
// clearing the SharedPreferences
mSharedPrefernce.edit().clear();
endTime = System.currentTimeMillis();
Log.v("info", "endTime=" + endTime);
long totalTime =0;
totalTime = endTime - start;
DateFormat df = new SimpleDateFormat("HH':'mm':'ss");
df.setTimeZone(TimeZone.getTimeZone("GMT+0"));
duration = df.format(new Date(totalTime));
// inserting the call details into sqlite db
dba.insertDetails(phonenumber, date1, time1, duration, type);
}
}
}
我也在清单文件中添加了如下所示的权限...
<receiver android:name="IncomingCallReceiver" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
<action android:name="android.intent.action.NEW_OUTGOING_CALL" >
</action>
</intent-filter>
</receiver>
