I am new to Android Developing, am getting this error:
android.content.res.Resources$NotFoundException: Resource ID #0x7f070075
whenever I set the adapter to the Recycle View myrv.setAdapter(myAdapter); everything seems to be properly coded, I have checked many times my code and I am unable to find what is causing this.
Here is my code
package com.example.root.agenda;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.GridLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import java.util.ArrayList;
import java.util.List;
public class MainActivity extends AppCompatActivity {
List<Contact> lstContact;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
lstContact = new ArrayList<>();
lstContact.add(new Contact("Andrea", "5874-2563", "Normal", R.drawable.user_painted_black64));
lstContact.add(new Contact("Daniela", "2013-2365", "Normal", R.drawable.user_black));
lstContact.add(new Contact("Juan", "7584-2323", "Normal", R.drawable.user_painted64));
lstContact.add(new Contact("Elena", "7541-2110", "Normal", R.drawable.user_painted_black64));
lstContact.add(new Contact("Maria", "7504-2000", "Normal", R.drawable.user_painted_white64_1));
lstContact.add(new Contact("Edgardo", "2048-2048", "Normal", R.drawable.user_painted_white64_1));
lstContact.add(new Contact("Alfonso", "9514-3214", "Normal", R.drawable.user_painted_black64));
lstContact.add(new Contact("Erick", "5412-3652", "Normal", R.drawable.user_painted_white64_1));
lstContact.add(new Contact("Andrea", "5874-2563", "Normal", R.drawable.user_painted_black64));
lstContact.add(new Contact("Daniela", "2013-2365", "Normal", R.drawable.user_black));
RecyclerView myrv = (RecyclerView) findViewById(R.id.id_recyclerView);
RecyclerViewAdapter myAdapter = new RecyclerViewAdapter(this, lstContact);
myrv.setLayoutManager(new GridLayoutManager(this, 3));
myrv.setAdapter(myAdapter);
/* FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});*/
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement

return true;
}
return super.onOptionsItemSelected(item);
}
}
For the Recycler View
package com.example.root.agenda;

import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;

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<Contact> mData;
public RecyclerViewAdapter(Context mContext, List<Contact> mData) {
this.mContext = mContext;
this.mData = mData;
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view;
LayoutInflater mInflater = LayoutInflater.from(mContext);
view = mInflater.inflate(R.layout.cardview_contact_layout, parent, false);
return new MyViewHolder(view);
}
@Override
public void onBindViewHolder(MyViewHolder holder, final int position) {
holder.tv_contact_name.setText(mData.get(position).getNombre());
holder.img_contact_thumbnail.setImageResource(mData.get(position).getThumbnail());
holder.cardView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//pasando datos al detalle de contacto
Intent intent = new Intent(mContext, Contact_details_activity.class);
intent.putExtra("Nombre", mData.get(position).getNombre());
intent.putExtra("Numero de Telefono", mData.get(position).getTelefono());
intent.putExtra("Thumbnail", mData.get(position).getThumbnail());
mContext.startActivity(intent);
}
});
//Click Listener
}
@Override
public int getItemCount() {
return mData.size();
}
public static class MyViewHolder extends RecyclerView.ViewHolder{
TextView tv_contact_name;
ImageView img_contact_thumbnail;
CardView cardView;
public MyViewHolder(View itemView) {
super(itemView);
tv_contact_name = (TextView) itemView.findViewById(R.id.id_contact_name);
img_contact_thumbnail = (ImageView) itemView.findViewById(R.id.id_contact_img);
cardView = (CardView) itemView.findViewById(R.id.id_cardview);
}
}
}
