[英]How to start new intent in myadapter
I'm creating a foodrecipe app and i need help with starting a new intent in my adapter.class. 我正在创建foodrecipe应用程序,并且需要有关在adapter.class中启动新意图的帮助。 i know normally you use Context context in de default constructer and then you can startactivity.
我知道通常您在默认构造函数中使用Context上下文,然后就可以开始活动了。
and i tried to use Context in my constructer but i can't 我试图在我的构造函数中使用上下文,但是我不能
MyAdapter MyAdapter
public class Myadapter extends FirestoreRecyclerAdapter<Note, Myadapter.MyHolder> {
public Myadapter(@NonNull FirestoreRecyclerOptions<Note> options) {
super(options);
}
@Override
protected void onBindViewHolder(@NonNull MyHolder holder, int position, @NonNull Note model) {
holder.textViewname.setText(model.getNamerecipe());
holder.textViewinfo.setText(model.getInforecipe());
final String getname = holder.textViewname.getText().toString();
}
@NonNull
@Override
public MyHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.cardview, parent, false);
return new MyHolder(v);
}
class MyHolder extends RecyclerView.ViewHolder{
TextView textViewinfo;
TextView textViewname;
ImageView imageView;
Context context;
public MyHolder(@NonNull View itemView) {
super(itemView);
textViewinfo = itemView.findViewById(R.id.text_view_desciption);
textViewname = itemView.findViewById(R.id.text_view_title);
imageView = itemView.findViewById(R.id.Imageview);
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(context, Recipeinfo.class);
context.startActivity(intent);
}
});
}
}
}
If someone can help me it would be great, 如果有人可以帮助我,那就太好了,
You can get the context
from the view
itself, doing : 您可以从
view
本身获取context
,方法是:
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), Recipeinfo.class);
context.startActivity(intent);
}
});
And context
should be in the constructor of your Adapter
. context
应该在Adapter
的构造函数中。
private Context mContext;
public Myadapter(@NonNull FirestoreRecyclerOptions<Note> options, Context context) {
super(options);
this.mContext = context;
}
