항목 추가, 대신 ListView에의 그 자체. – LearnPainLess

항목이 TextView가 아니고 문자열을 추가 할 때 java.lang.UnsupportedOperationException이 발생했습니다. –

StringAdapterAdapter 문자열 유형을 사용하고 있으며 사용자 정의 항목을 추가 할 수 없으며 사용자 정의 어댑터를 만들 수 있습니다. – LearnPainLess

TextView을 동적으로 할당하는 대신 TextView에 들어있는 레이아웃의 ID 만 전달하면됩니다. TextView 만있는 맞춤 레이아웃을 만들거나 Android sdk 자체에서 제공하는 기본 템플릿 레이아웃을 사용할 수 있습니다. 예 :

android.R.layout.simple_list_item_1

전체 예제 :의 ListView의 어댑터

ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(context,android.R.layout.simple_list_item_1,list);

답장을 위해 ty, 내 코드를 수정했습니다. 왜이 예외가 throw됩니까? –

기다려 보겠습니다. – LearnPainLess

예, ArrayAdapter에는 TextView에 포함 된 레이아웃이 필요했습니다. – LearnPainLess
