RecyclerView只可以設(shè)置OnItemTouchListener弊知，那么既然可以設(shè)置監(jiān)聽(tīng)觸摸事件瞳脓，就可以從中解析獲取點(diǎn)擊、長(zhǎng)按...事件了景用。
定義自己需要的回調(diào)接口
public interface RVItemClickListener {
void onClick(View view, int position);
void onLongClick(View view, int position);
}
重新實(shí)現(xiàn)自己的OnItemTouchListener
public class RVItemTouchListener implements RecyclerView.OnItemTouchListener {
private GestureDetector gestureDetector;
private RVItemClickListener clickListener;
public RVItemTouchListener(Context context, final RecyclerView recyclerView, final RVItemClickListener clickListener) {
this.clickListener = clickListener;
gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
@Override
public boolean onSingleTapUp(MotionEvent e) {
return true;
}
@Override
public void onLongPress(MotionEvent e) {
View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
if (child != null && clickListener != null) {
clickListener.onLongClick(child, recyclerView.getChildLayoutPosition(child));
}
}
});
}
@Override
public boolean onInterceptTouchEvent(RecyclerView recyclerView, MotionEvent e) {
View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
if (child != null && clickListener != null && gestureDetector.onTouchEvent(e)) {
clickListener.onClick(child, recyclerView.getChildLayoutPosition(child));
}
return false;
}
@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}
@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
}
使用
recyclerView.addOnItemTouchListener(new RVItemTouchListener(this, recyclerView, new RVItemClickListener() {
@Override
public void onClick(View view, int position) {
}
@Override
public void onLongClick(View view, int position) {
}
}));
