实现RecyclerView的OnItemClick的姿势

RecyclerView只可以设置OnItemTouchListener,那么既然可以设置监听触摸事件,就可以从中解析获取点击、长按...事件了。
定义自己需要的回调接口
public interface RVItemClickListener {
void onClick(View view, int position);
void onLongClick(View view, int position);
}
重新实现自己的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) {
}
}));
