Android Gallery Grid On 선택되지 않았습니다.

Question

여기에 이미 코드가 있지만 다른 문제가 있습니다. 주 활동에서 볼 수 있듯이 gridview에 표시된 이미지에 대해 onItemClick 이벤트가 있지만 문제는 그림을 클릭 할 때 눈에 띄지 않는 것이 있다는 것입니다.

     gridView.setOnItemClickListener(new OnItemClickListener() {

        int position, long id) {

      holder = new ViewHolder();

     } else {

     ImageItem item = data.get(position); 
     holder.imageTitle.setText(item.getTitle());

어떻게 해결할 수 있습니까?

감사합니다.

Answer 1

rowgrid LinearLayout에서 android : clickable 속성을 제거하십시오. GridView가 가져 오기 전에 이벤트를 캡처합니다. 그래서 모든 onClick 및 onLongClick을 GridView의 onItemClick 및 onItemLongClick Listener에 바인딩하십시오. 행운을 비네.
