이제 파일에서 활동 이름을 추출하고 싶습니다. 그것은 다음과 유사한 각 라인에서 추출 할 난 단지 문자열 com.amazon.mobileads.mraid.MraidBrowser 다른 부분의에게 필요한이 줄에서

09-03 18:29:15.609 479 1039 I ActivityManager: Starting: Intent { flg=0x10000000 cmp=com.amazon.mShop.android/com.amazon.mobileads.mraid.MraidBrowser (has extras) } from pid 19164 

또는

09-03 17:12:08.601 479 620 I ActivityManager: Resumed Activity: com.amazon.mShop.android/com.amazon.mShop.search.SearchActivity totalTime: 4037 ms 

입니다 라인을 제거해야합니다. 시작 : 의도 또는 ActivityManager : 재개 된 작업 :을 제거해야합니다. 내가 좋아하는 캐릭터 라인의 순서를해야합니다 결국

,

com.amazon.mobileads.mraid.MraidBrowser 

com.amazon.mShop.search.SearchActivity 

그래서 자신의 라인 수에 따라합니다.

어떻게하면됩니까? 내가 tokenizer 문자열을 사용할 수 있지만 지루하고 비효율적 인 프로세스, 정규식 또는 뭔가 비슷한 것이 더 좋을 것이라고 생각합니다.

Answer 1

당신은 이 1 군에 저장됩니다 정규식

ActivityManager: (?:Starting: Intent.*?cmp=|Resumed Activity:\s*)(\S+) 

당신의 원하는 문자열을 시도 할 수 있습니다.

는 here on Regexr

모든 백 슬래시를 이스케이프 자바에서이 정규식을, 당신이 사용을 참조하십시오, 그래서 첫 번째 부분은 부분까지 "ActivityManager"에서 문자열과 일치

ActivityManager: (?:Starting: Intent.*?cmp=|Resumed Activity:\\s*)(\\S+) 

처럼 보일한다 당신은 추출물을 원하고 마지막 부분 인 (\\S+)은 공백이 아닌 일련의 문자와 일치하고 그것을 그룹 1에 저장합니다.

Answer 2

내 접근법이 전혀 귀엽지 않을 수도 있지만 작동합니다. 업데이트]

String filePath = "res/textfile.txt"; 
String line; 
List<String> myL = new ArrayList<String>(); 

try { 
    BufferedReader read = new BufferedReader(new FileReader(filePath)); 
    while((line = read.readLine()) != null) { 
     if(line.contains("Resumed Activity") || line.contains("Starting: Intent")) { 
      String str[] = line.split(" "); 
      for(String s : str) { 
       if(s.contains("com.amazon")) 
        myL.add(s); 
      } 
     } 
    } 

    for(String s : myL) { 
     System.out.println(s); 
    } 

} catch (FileNotFoundException e) { 
    e.printStackTrace(); 
} catch (IOException e) { 
    e.printStackTrace(); 
} 

: 난 그냥 내 솔루션을 다시 귀하의 게시물을 읽고 업데이트 하나의 해결책이 될 것입니다. 나는 "Resumed Activity"또는 "Starting : Intent"등의 줄이 제거되어야한다고 생각합니다.
