무엇이 잘못하고 있습니까?

미리 감사드립니다

Answer 1

로그 캣은 명확하게 당신이 제공하는 것은있는 LinearLayout이 같은 텍스트 뷰에 대한 리소스 ID를 제공해야한다고 (내 추측은 ClassCastException을 던지기 때문에) main.xml은 linearlayout이고 textview가 아니라고 생각합니다. 대신 시도하십시오 R.id.ringtone

Answer 2

당신의 문제가이 선에 설명되어 사전에

감사합니다 :

11:05:08.473: ERROR/AndroidRuntime(715): Caused by: java.lang.ClassCastException: android.widget.LinearLayout 
04-27 11:05:08.473: ERROR/AndroidRuntime(715):  at android.widget.ArrayAdapter.createViewFromResource(ArrayAdapter.java:340) 

그것은 아마 하나가없는 상태에서하는 LinearLayout으로 뭔가를 사용하는 것을 의미한다.
은 (당신이
foobar = (LinearLayout) someCode(); 같은 일을하고있는 ClassCastException를 얻을 대부분의 시간)

Answer 3

잘 친구 귀하의 문제는 당신이 목록 행에 대한 r.layout.main를 사용하고 있습니다.

당신은 당신은 단지 텍스트 뷰 을 언급의 separete listrow 레이아웃을 생성하고 하여 오류가

setListAdapter(new ArrayAdapter<String>(FindFilesByType.this, R.layout.main, 
       Ringtones)); 

는 레이아웃을 만들이 라인에 배치로 전달해야 listrow.xml

<?xml version="1.0" encoding="utf-8"?> 
<TexView 
..... 
/> 

말

및

setListAdapter(new ArrayAdapter<String>(FindFilesByType.this, R.layout.listrow, 
        Ringtones));
