android에서 어댑터의 childview 가져 오기

Question

2 개의 레이아웃이있는 어댑터가 있고 세부 사항이있는 노래 항목은 두 번째 레이아웃이고 현재 노래 선택 레이아웃의 재생 위치에 대한 탐색 표시 줄과 세부 정보가있는 노래 항목입니다. 내 어댑터는 여기에 있습니다 : 사용자가 onItemClickListener를 사용하여 어댑터를 클릭 할 때 난 단지 SeekBar를 설정이 어댑터에서

가 표시 할 다음 내가 선택한 어댑터의 SeekBar를 얻을 싶어요. 내가 어떻게 해? 나는 이와 같은 방법을 만들었지 만 일하지는 않는다.

public Seekbar getSeekbar(){ 
    ViewHolder view=(ViewHolder)getView(currentlyPlay,null,null); 
    return view.seekBar; 
} 

나는 내가 현재 위치를 선택한보기를 얻을 수 있습니다 내 onItemClick에 currentlyPlay보기를 설정 .. 그러나 그것은 나를 위해 작동하지 않습니다 ... 당신이 도와 드릴까요?

Answer 1

당신은 내가 clickedView.findViewById (R.id.seek_lagu)를 사용할 수 있습니다

View clickedView = yourAdapter.getView(position, null, null);
