Asynctask, asynchronous processing, is mainly used to separate time-consuming operations from the main thread (ui thread) for processing, improving the Running Speed (smoothness ). I was going to learn about asynctask. When I saw the time-consuming operation, I considered reading large files and tried to read the files in the raw folder.
There are two ways to read, one is reading by row, and the other is reading by size;
MainCodeAs follows:
1. Read data by row

 Class Filereadtask Extends Asynctask <string, String, string>{String line_str; string result; Context context; filereadtask (context ){  This . Context = Context ;}  Int I = 0 ; @ Override  Protected  String doinbackground (string... Params) {bufferedreader Reader = New Bufferedreader ( New Inputstreamreader (context. getresources (). openrawresource (R. Raw. Test2 )));  Try  {  While (Line_str = reader. Readline ())! = Null &&! (Line_str = reader. Readline (). Equals ("" ) {Result + = Line_str; system. Out. println ( "Line_str:" +Line_str); publishprogress (line_str);} system. Out. println ( "Result:" + Result );}  Catch  (Ioexception e) {e. printstacktrace ();}  Return  Line_str ;}@ override  Protected   Void  Onpostexecute (string result ){ Super  . Onpostexecute (result) ;}@ override  Protected   Void  Onpreexecute (){  Super  . Onpreexecute () ;}@ override  Protected   Void  Onprogressupdate (string... values ){  Super . Onprogressupdate (Values [0]); System. Out. println ( "Values:" + values [0 ]); Array. Add (Values [ 0 ]); Adapter. notifydatasetchanged ();}} 

Ii. Read by size

Inputstream input = Context. getresources (). openrawresource (R. Raw. Test2); string result = Null  ;  Int  I;  Byte [] By = New  Byte [128]; //  Size of each read                   Try  {  While (I = input. Read (by)> 0 ){  Byte [] Bys = New   Byte  [I]; input. Read (bys, 0 , I); string s = New String (bys); Result + = S; system. Out. println (s );}}  Catch  (Ioexception e) {e. printstacktrace ();}
