I want to add startActivity()
to my onClick
listeners in my CustomAdapter class.
CustomAdapter.java
:
JavaScript
x
import android.content.Intent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import android.widget.Toast;
import androidx.recyclerview.widget.RecyclerView;
import java.util.List;
import static androidx.core.content.ContextCompat.startActivity;
public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.ViewHolder> {
private List<String> data;
public CustomAdapter (List<String> data){
this.data = data;
}
@Override
public CustomAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View rowItem = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item_view, parent, false);
return new ViewHolder(rowItem);
}
@Override
public void onBindViewHolder(CustomAdapter.ViewHolder holder, int position) {
holder.textView.setText(this.data.get(position));
}
@Override
public int getItemCount() {
return this.data.size();
}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
private TextView textView;
public ViewHolder(View view) {
super(view);
view.setOnClickListener(this);
this.textView = view.findViewById(R.id.textview);
}
@Override
public void onClick(View view) {
startActivity(new Intent(CustomAdapter.this, LoginActivity.class));
}
}
}
The problem is I’m getting the following error in my IDE:
JavaScript
Cannot resolve constructor 'Intent(com.kenadams.app.CustomAdapter, java.lang.Class<com.kenadams.app.LoginActivity>)'
Initially , I thought this was happening because my CustomAdapter
class was static
. So, I made it non-static. But, the problem still persists. Pls guide me on making this intent work.

Answer
In you customer adapter class you need to get context using constructor.
JavaScript
private Context mcon;
and in constructor->
JavaScript
public CustomAdapter (Context _mcon, List<String> data){
this.mcon = _mcon;
this.data = data;
}
and then in onClickListener->
JavaScript
@Override
public void onClick(View view) {
mcon.startActivity(new Intent(mcon, LoginActivity.class));
}
