试试下面一个
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
final Myholder myholder = (Myholder) holder;
DataFood current = data.get(position);
myholder.textFoodname.setText(current.foodName);
myholder.textPrice.setText("Rp. " + current.price);
myholder.textId.setText(String.valueOf(current.foodId));
Glide.with(context).load(current.foodImage).asBitmap()
.into(myholder.ivFood);
myholder.cardView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DataFood clickedDataItem = data.get(position);
Intent intent = new Intent(context, Order.class);
intent.putExtra("nama", data.get(position).foodName);
intent.putExtra("harga", data.get(position).price);
intent.putExtra("gambar", data.get(position).foodImage);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
Toast.makeText(v.getContext(), "clicked" + clickedDataItem.foodName, Toast.LENGTH_LONG).show();
}
});
}
并在Myholder类中更新此内容
class Myholder extends RecyclerView.ViewHolder {
TextView textFoodname, textPrice, textId;
ImageView ivFood;
CardView cardView;
public Myholder(View view) {
super(view);
textFoodname = (TextView) view.findViewById(R.id.textFoodname);
ivFood = (ImageView) view.findViewById(R.id.ivFood);
textId = (TextView) view.findViewById(R.id.textid);
textPrice = (TextView) view.findViewById(R.id.textPrice);
cardView = (CardView) itemView.findViewById(R.id.cv);
}
}
您已设置2个可单击项，因此无法单击该项
Just remove one clickable from layout which is not using it, keep only the one which used in layout identifer:
android:clickable="true"
注意：在您的情况下，请删除所有
如果您使用recyclerView，您应该尝试“回调接口”
AdapterFood.class
public interface OnItemClickLitener {
void onItemClick(View view, int position);
}
private OnItemClickLitener mOnItemClickLitener;
public void setOnItemClickListener(OnItemClickLitener mOnItemClickLitener) {
this.mOnItemClickLitener = mOnItemClickLitener;
}
@Override
public void onBindViewHolder(final RecyclerView.ViewHolder holder, int position) {
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mOnItemClickLitener. onItemClick();
}
}
Myholder
class Myholder extends RecyclerView.ViewHolder {
TextView textFoodname, textPrice, textId;
ImageView ivFood;
CardView cardView;
public Myholder(View view) {
super(view);
textFoodname = (TextView) view.findViewById(R.id.textFoodname);
ivFood = (ImageView) view.findViewById(R.id.ivFood);
textId = (TextView) view.findViewById(R.id.textid);
textPrice = (TextView) view.findViewById(R.id.textPrice);
cardView = (CardView) itemView.findViewById(R.id.cv);
}
}
mAdapter.setOnItemClickListener(new CourseListAdp.OnItemClickLitener() {
@Override
public void onItemClick(View view, int position) {
//your work
int pos = position;
if (pos != RecyclerView.NO_POSITION){
**********
**********
}
}
}
开胃菜
class Myholder extends RecyclerView.ViewHolder {
TextView textFoodname, textPrice, textId;
ImageView ivFood;
CardView cardView;
public Myholder(View view) {
super(view);
textFoodname = (TextView) view.findViewById(R.id.textFoodname);
ivFood = (ImageView) view.findViewById(R.id.ivFood);
textId = (TextView) view.findViewById(R.id.textid);
textPrice = (TextView) view.findViewById(R.id.textPrice);
