I do not know if I asked the question correctly, but come on, who can help me thank you:)
This is my second MainActivity, I am doing an application with navigation drawer and in it to do the other screens of the menu I am using the fragments, however I want to make a list in each menu, but I do not know how to do it inside a class which extends fragment ...
public class Main2Activity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL,false);
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.my_recyvlerview);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(new MyAdapter(this));
}
}
Here is the adapter:
public class MyAdapter extends RecyclerView.Adapter {
Context context;
// array para receber as imagens
ArrayList<Bitmap> images = new ArrayList<Bitmap>();
public MyAdapter(Context context) {
this.context = context;
// imagens
images.add(BitmapFactory.decodeResource(context.getResources(),R.drawable.tn_gpx15));
images.add(BitmapFactory.decodeResource(context.getResources(),R.drawable.tn_gpx19));
images.add(BitmapFactory.decodeResource(context.getResources(),R.drawable.tn_tb));
images.add(BitmapFactory.decodeResource(context.getResources(),R.drawable.tn_gpx15));
images.add(BitmapFactory.decodeResource(context.getResources(),R.drawable.tn_gpx19));
images.add(BitmapFactory.decodeResource(context.getResources(),R.drawable.tn_tb));
}
public MyAdapter(Fragment_main fragment_main) {
}
@Override
public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.row, parent, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(MyAdapter.ViewHolder holder, int position) {
// setando imagens, posições.
holder.imageView.setImageBitmap(images.get(position));
}
@Override
public int getItemCount() {
return images.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
ImageView imageView;
public ViewHolder(View itemView) {
super(itemView);
imageView = (ImageView) itemView.findViewById(R.id.my_imagesview);
}
}
So far so good, everything works fine and returns me to the image list,
But I wanted to do the same thing in the fragment, there I tried to do the same thing,
public class Fragment_main extends Fragment {
RecyclerView recyclerView2;
public Fragment_main() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View Acess = inflater.inflate(R.layout.fragment_main, container, false);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL,false);
RecyclerView recyclerView = (RecyclerView) Acess.findViewById(R.id.my_recyvlerview2);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(new MyAdapter(this));
return Acess;
}
}
however in the LinearLayoutManager (this, LinearLayoutManager.VERTICAL, false) excerpt; is accusing that it is not compatible in the context part.
I wanted to know how to resolve this and display this list in the fragment layout ...
