Question

嘿，我想从Android CallLog获取通话时间。它是用户启动呼叫的正好时间，如果可能的话，当他完成呼叫时。有人知道怎么做？

谢谢！

Answer 1

这是完整的解决方案（虽然没有经过测试） - 只是方案：

public void logCallLog(String number)
{
    long dialed;
    String columns[]=new String[] {
            CallLog.Calls._ID, 
            CallLog.Calls.NUMBER, 
            CallLog.Calls.DATE, 
            CallLog.Calls.DURATION, 
            CallLog.Calls.TYPE};
    String args[]=new String[1];
    args[0]=number;
    Cursor c;
    c = this.managedQuery(Uri.parse("content://call_log/calls"),
            columns, CallLog.Calls.NUMBER+"=?", args, "Calls._ID DESC"); //last record first
    while (c.moveToNext())
    {
        dialed=c.getLong(c.getColumnIndex(CallLog.Calls.DATE));
        Log.i("CallLog", "Call to number: "+number+", registered at: "+new Date(dialed).toString());
    }
}

专注于原始问题，这是一个基于@barmaley的解决方案：

public void logCallLog(String number)
{
    long dialed;
    String columns[]=new String[] {
            CallLog.Calls._ID, 
            CallLog.Calls.NUMBER, 
            CallLog.Calls.DATE, 
            CallLog.Calls.DURATION, 
            CallLog.Calls.TYPE};
    String args[]=new String[1];
    args[0]=number;
    Cursor c;
    c = this.managedQuery(Uri.parse("content://call_log/calls"), columns, CallLog.Calls.NUMBER+"=?", args, "Calls._ID DESC"); //last record first
    while (c.moveToNext())
    {
        int duration = c.getInt(c.getColumnIndex(CallLog.Calls.DURATION));// for duration in seconds            
        dialed=c.getLong(c.getColumnIndex(CallLog.Calls.DATE));
        GregorianCalendar callStart = new GregorianCalendar();
        callStart.setTimeInMillis(dialed);
        int hstart = callStart.get(GregorianCalendar.HOUR_OF_DAY);

        //using callStart and duration you can calculate the end hour:
        dialed += duration+1000;
        GregorianCalendar callEnd = new GregorianCalendar();
        callEnd.setTimeInMillis(dialed);
        int hend = callEnd.get(GregorianCalendar.HOUR_OF_DAY);

        Log.i("CallLog", String.format("Start:%d End:%d", hstart, hend));
    }
}
