我获得的是上一个呼叫持续时间而不是最后一个呼叫持续时间

Question

我尝试了以下代码，因为获得的通话持续时间不正确，以前的通话时长显示为当前电话。我尝试了代码并搜索了堆栈溢出，问题没有解决。

private int outgoingCallDuration(Context context) {
int sum = 0;
StringBuffer sb = new StringBuffer();

try {
//
Cursor managedCursor = context.getContentResolver().query(android.provider.CallLog.Calls.CONTENT_URI, null, null, null, null);
int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER);
int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE);
int date = managedCursor.getColumnIndex(CallLog.Calls.DATE);
int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION);
sb.append("Call Details :");
Log.e("total count", "" + managedCursor.getCount());
//managedCursor.moveToPosition(managedCursor.getCount() - 1);
int currentCount = 0, lastPosition = 0;
while (managedCursor.moveToNext()) {
currentCount++;
//managedCursor.moveToPosition(managedCursor.getCount() - 1);
String phNumber = managedCursor.getString(number);
String callType = managedCursor.getString(type);
String callDate = managedCursor.getString(date);
java.sql.Date callDayTime = new java.sql.Date(Long.valueOf(callDate));
String callDurations = managedCursor.getString(duration);
String dir = null;
int dircode = Integer.parseInt(callType);

switch (dircode) {
case CallLog.Calls.OUTGOING_TYPE:
//  lastPosition = currentCount;
dir = "OUTGOING";
break;
case CallLog.Calls.INCOMING_TYPE:
dir = "INCOMING";
break;
case CallLog.Calls.MISSED_TYPE:
dir = "MISSED";
break;
}
lastPosition = currentCount;
}
lastPosition--;
//          managedCursor.moveToLast();
managedCursor.moveToPosition(lastPosition);
int requiredNumber = managedCursor.getColumnIndex(CallLog.Calls.NUMBER);
int durations = managedCursor.getColumnIndex(CallLog.Calls.DURATION);
String phNumber = managedCursor.getString(requiredNumber);
String dur = managedCursor.getString(durations);
//  Long durat = Long.parseLong(dur);
int myNum = Integer.parseInt(dur);
managedCursor.close();
Log.e("last position number ", phNumber);
Log.e("last position duration ", dur);
return myNum;
} catch (SecurityException ex) {
Log.d("CallReceiver", "outgoingCallDuration: Permission to read call is not allowed by user!");
return 0;
}
}

请帮助我如何解决这个问题。如何在安卓中获取最后一次通话持续时间。

Answer 1

您需要在内容查询中使用限制子句来获取上次调用的详细信息。因此，您的内容查询将成为

Cursor cur = getContentResolver().query( CallLog.Calls.CONTENT_URI,null, null,null, android.provider.CallLog.Calls.DATE + " DESC limit 1;");

Answer 2

试试这个代码：

public double getLastOutgoingCallDuration(Context context) {
Cursor c = context.getContentResolver()
.query(CallLog.Calls.CONTENT_URI, null, null, null, null);
double callDuration = 0;
if (c != null) {
while (c.moveToNext()) {
int type = Integer.parseInt(c.getString(c.getColumnIndex(CallLog.Calls.TYPE)));
String duration = c.getString(c.getColumnIndex(CallLog.Calls.DURATION));
if (type == CallLog.Calls.OUTGOING_TYPE)
callDuration = Double.parseDouble(duration);
c.close();
}
}
return callDuration;
}
