concat

问题 I must concat 2 or more audio (wav or mp3) files and get one audio file. How can I do that in android? Thanks in advance. 回答1: The below code section will work as how many selections have been made.Selection means how much files are selected. Put your two wav files in /sdcard0/SSoftAudioFiles/ as 1.wav and 2.wav. And Just execute this method. public void SSoftAudCombine() { try { String[] selection=new String[2]; selection[0]="1.wav"; selection[1]="2.wav"; DataOutputStream amplifyOutputStream

问题 My question is closely related to Pandas Merge - How to avoid duplicating columns but not identical. I want to concatenate the columns that are different in three dataframes. The dataframes have a column id, and some columns that are identical: Ex. df1 id place name qty unit A 1 NY Tom 2 10 a 2 TK Ron 3 15 a 3 Lon Don 5 90 a 4 Hk Sam 4 49 a df2 id place name qty unit B 1 NY Tom 2 10 b 2 TK Ron 3 15 b 3 Lon Don 5 90 b 4 Hk Sam 4 49 b df3 id place name qty unit C D 1 NY Tom 2 10 c d 2 TK Ron 3

问题 Updating the Question: @Mouser, thank you for this answer. though I'm sure the code is fine, it actually doesn't do anything. I believe it is because I run the script right after the elements in the body section. So, the list is created, and then the code is run and the source of the listimgx changes, but how can I make it actually show the named src? At its current state, page loads, text items change, but the pictures don't. I tried adding a class to ul and adding a listview refresh at the

问题 This is a follow on question from my original question which has helped me solve the first part of my script: Autofill unknown amount of cells. The second part of my script is to concatenate an unknown number of cells. Using the logic from the first question I have tried to alter my script for to this myconcatenate = ActiveCell.FormulaArray = "=Concatenate("A5", mylastcell_4)" But it is resulting in a syntax error. Originally I was given this piece of script which worked fine on its own but

问题 Can anyone tell me how I can use a result from a CONCAT as a columnname during SELECT? My attempt looks like this: INSERT INTO `table_1` (datum, comment) SELECT CURRENT_DATE(), CONCAT('s',DAYOFWEEK(CURRENT_DATE())-1) FROM `table_2` WHERE id = 12345 As a result I get s0 - s6 as a value in my comment field instead of the value that is actually in my 2nd table that I want to read the value from :/ funfact: If I just type in s0 (as an example, works with all 7) instead of the CONCAT, it works
