I am displaying the data in CardView from SQLite database. But I get error while displaying the data, I checked my code and it seems perfect, there might be some silly mistake. I am newbie to android. Any help is appreciated.
Here is RecyclerViewAdapter.java file
import android.content.Context;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.text.Layout;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.List;
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.MyViewHolder> {
private Context mContext;
private List<Card> mData;
public RecyclerViewAdapter(Context mContext, List<Card> mData) {
this.mContext = mContext;
this.mData = mData;
}
@NonNull
@Override
public MyViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
View view;
LayoutInflater mInflator = LayoutInflater.from(mContext);
view = mInflator.inflate(R.layout.home_view, viewGroup, false);
return new MyViewHolder(view);
}
@Override
public void onBindViewHolder(@NonNull MyViewHolder myViewHolder, int i) {
Card mcard = mData.get(i);
myViewHolder.title.setText(mcard.getTitle());
}
@Override
public int getItemCount() {
return mData.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder{
public TextView title;
public MyViewHolder(View itemView){
super(itemView);
title = (TextView) itemView.findViewById(R.id.title);
}
}
}
This is home_view.xml which contains a TextView inside CardView.
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_rowWeight="1"
android:layout_columnWeight="1"
android:layout_margin="12dp"
android:onClick="showDetails">
<RelativeLayout
android:id="@+id/c1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="16dp">
<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="12dp"
android:textColor="#6f6f6f"
android:textSize="18sp"/>
</RelativeLayout>
</android.support.v7.widget.CardView>
I am getting this error

Quit this:
myViewHolder.title.setText(mcard.getTitle());
From the onBind() and put it into the constructor of MyViewHolder
Is the problem.
I solved it by myself.
I forget to cast the value of mcard.getTitle()
to String
myViewHolder.title.setText(String.valueOf(mcard.getTitle()));
