ListView의 Listitem이 밝지 않다.

Question

사용자가 환자를 검색 할 수있는 응용 프로그램을 만들고 있습니다. 사용자가 환자를 검색하면 결과가 목록보기로 표시됩니다. 그러나 문제는 응용 프로그램의 아래 스크린 샷에서 볼 수 있듯이 사용자가 제대로 볼 수있을 정도로 결과가 밝지 않다는 것입니다 (환자 검색 버튼 아래에 결과는 1234567890, abc, xyz로 표시됨). 철저하게 참조하십시오.) 내가 제대로 밝게 만드는 방법을 알고하지 않습니다

. 같은 문제가 실제 Android 기기에도 나타납니다. 누군가 나를 도울 수 있습니다.

봅니다 어댑터에 다른 Context을 통과 :

를

new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1);
