RecycleView设置点击的两种方式：adapter中的onBindViewHolder(VH,int)方法中进行；实现RecyclerView的addonItemTouchListerner()

class HomeAdapter extends RecyclerView.Adapter<HomeAdapter.MyViewHolder>
{

//...
public interface OnItemClickLitener
{
void onItemClick(View view, int position);
void onItemLongClick(View view , int position);
}

private OnItemClickLitener mOnItemClickLitener;

public void setOnItemClickLitener(OnItemClickLitener mOnItemClickLitener)
{
this.mOnItemClickLitener = mOnItemClickLitener;
}

@Override
public void onBindViewHolder(final MyViewHolder holder, final int position)
{
holder.tv.setText(mDatas.get(position));

// 如果设置了回调，则设置点击事件
if (mOnItemClickLitener != null)
{
holder.itemView.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
int pos = holder.getLayoutPosition();
mOnItemClickLitener.onItemClick(holder.itemView, pos);
}
});

holder.itemView.setOnLongClickListener(new OnLongClickListener()
{
@Override
public boolean onLongClick(View v)
{
int pos = holder.getLayoutPosition();
mOnItemClickLitener.onItemLongClick(holder.itemView, pos);
return false;
}
});
}
}
//...
}

mAdapter.setOnItemClickLitener(new OnItemClickLitener()
{

@Override
public void onItemClick(View view, int position)
{
Toast.makeText(HomeActivity.this, position + " click",
Toast.LENGTH_SHORT).show();
}

@Override
public void onItemLongClick(View view, int position)
{
Toast.makeText(HomeActivity.this, position + " long click",
Toast.LENGTH_SHORT).show();
mAdapter.removeData(position);
}
});
