recycle view won't recieve a bundle data

i'm trying to pass a bundle from a product detail activity to a cart with a recycle view but when i click on add to cart the cart is opened but remains empty i don't know what's wrong with the code
here is the first activity
public class product_details extends AppCompatActivity {
ImageView product_img, share;
TextView name, price;
public int img;
public int price1;
public String name1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_product_details);
product_img = (ImageView) findViewById(R.id.Product_Img);
name = (TextView) findViewById(R.id.product_name);
price = (TextView) findViewById(R.id.product_price);
share = (ImageView) findViewById(R.id.share);
img = getIntent().getIntExtra("img", 00);
Glide.with(this).load(img).into(product_img);
name1 = getIntent().getStringExtra("name");
name.setText(name1);
price1 = getIntent().getIntExtra("price", 0);
price.setText(String.valueOf(price1));
ImageView cart = (ImageView) findViewById(R.id.add_cart);
cart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), CartActivity.class);
Bundle extras = new Bundle();
extras.putString("price1", String.valueOf((price1)));
extras.putString("name1", name1);
extras.putString("img1",String.valueOf(img));
intent.putExtras(extras);
startActivity(intent);
}
my second activity class

Change the Icon of a Button in a Recycler View in Adapter Class Based off boolean value

I'm trying to change the icon of a button in my recycler view every time the activity starts based off a boolean value in my custom object. I assume this has to be done within the adapter since not every groups button will have the same background.
Below is the code for my recycler view adapter:
public class RecipeListAdapter extends RecyclerView.Adapter<RecipeListAdapter.ViewHolder>{
private List<Recipe> mRecipeSet;
private Button mAddToGroceriesButton;
public RecipeListAdapter(List<Recipe> recipes){
mRecipeSet = recipes;
}
// Provide a reference to the views for each data item
// Complex data items may need more than one view per item, and
// you provide access to all the views for a data item in a view holder
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
//This is what will handle what happens when you click a recipe in the recycler view
private TextView mRecipeName;
private TextView mPrepTime;
private TextView mCookTime;
private TextView mServingSize;
private RelativeLayout mRecipeTextSection;
public ViewHolder(View v) {
super(v);
mRecipeName = (TextView) v.findViewById(R.id.recipe_list_recycler_view_recipe_name);
mServingSize = (TextView) v.findViewById(R.id.recipe_list_recycler_view_serving_size);
mPrepTime = (TextView) v.findViewById(R.id.recipe_list_recycler_view_prep_time);
mCookTime = (TextView) v.findViewById(R.id.recipe_list_recycler_view_cook_time);
mRecipeTextSection = (RelativeLayout) v.findViewById(R.id.recycled_item_section_view);
mRecipeTextSection.setOnClickListener(this);
mAddToGroceriesButton = (Button) v.findViewById(R.id.add_to_grocery_list);
mAddToGroceriesButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int position = getAdapterPosition();
Recipe recipeToGrocery = mRecipeSet.get(position);
//RecipeDB dbHelper = new RecipeDB(v.getContext());
//dbHelper.addGroceryItem(recipeToGrocery);
if(!recipeToGrocery.isInList()) {
RecipeDB dbHelper = new RecipeDB(v.getContext());
dbHelper.addGroceryItem(recipeToGrocery);
recipeToGrocery.setInList(true);
dbHelper.updateRecipe(recipeToGrocery);
mAddToGroceriesButton.setBackgroundResource(R.mipmap.ic_playlist_add_check_black_24dp);
Toast.makeText(v.getContext(), recipeToGrocery.getRecipeName() + " added to grocery list.", Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(v.getContext(), "That recipe is already in the list.", Toast.LENGTH_SHORT).show();
}
}
});
}
#Override
public void onClick(View v){
int position = getAdapterPosition();
Intent i = new Intent(v.getContext(), RecipeTextView.class);
Recipe selectedRecipe = mRecipeSet.get(position);
i.putExtra("view_recipe_key", selectedRecipe);
v.getContext().startActivity(i);
}
}
public void add(int position, Recipe item) {
mRecipeSet.add(position, item);
notifyItemInserted(position);
}
public void remove(Recipe item) {
int position = mRecipeSet.indexOf(item);
mRecipeSet.remove(position);
notifyItemRemoved(position);
}
public RecipeListAdapter(ArrayList<Recipe> myRecipeset) {
mRecipeSet = myRecipeset;
}
// Create new views (invoked by the layout manager)
#Override
public RecipeListAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
// create a new view
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.recipe_item_recycled, parent, false);
ViewHolder vh = new ViewHolder(v);
return vh;
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
Recipe recipe = mRecipeSet.get(position);
String recipeName = recipe.getRecipeName();
String prepTime = "Prep Time: " + String.valueOf(recipe.getPrepTime()) + " minutes";
String cookTime = "Cook Time: " + String.valueOf(recipe.getCookTime()) + " minutes";
String servingSize = "Servings: " + String.valueOf(recipe.getServings());
holder.mRecipeName.setText(recipeName);
//Only display values if they are not null
if(recipe.getServings() != null) {
holder.mServingSize.setText(servingSize);
}
if (recipe.getPrepTime() != null) {
holder.mPrepTime.setText(prepTime);
}
if(recipe.getCookTime() != null) {
holder.mCookTime.setText(cookTime);
}
}
// Return the size of your dataset (invoked by the layout manager)
#Override
public int getItemCount() {
if(mRecipeSet != null) {
return mRecipeSet.size();
}
return 0;
}
}
I know how to change the background of the button when it's clicked with
mAddToGroceriesButton.setBackgroundResource(R.mipmap.ic_playlist_add_check_black_24dp);
but it's obviously not going to save the state of that button when the activity restarts. I'm just not sure of how to check the boolean value for each group upon activity start up and change the button background accordingly.
I tried using
if(recipe.isInList()){
mAddToGroceriesButton.setBackgroundResource(R.mipmap.ic_playlist_add_check_black_24dp);
}
in the onBindViewHolder method but it didn't do anything, and I'm pretty sure that wouldn't be the correct place for it anyways. I know the boolean is working properly since I use it in other places and it works fine.

Looks like you need to declare your button at the top of your ViewHolder with your other views. So move the declaration from the top of your adapter:
private Button mAddToGroceriesButton;
Then in your onBindViewHolder method you can get a reference to your button through the holder and set the background:
if(recipe.isInList()) {
holder.mAddToGroceriesButton.setBackgroundResource(R.mipmap.ic_playlist_add_check_black_24dp);
}

Try this,
public class RecipeListAdapter extends RecyclerView.Adapter<RecipeListAdapter.ViewHolder>{
private List<Recipe> mRecipeSet;
private Button mAddToGroceriesButton;
public RecipeListAdapter(List<Recipe> recipes){
mRecipeSet = recipes;
}
// Provide a reference to the views for each data item
// Complex data items may need more than one view per item, and
// you provide access to all the views for a data item in a view holder
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
//This is what will handle what happens when you click a recipe in the recycler view
private TextView mRecipeName;
private TextView mPrepTime;
private TextView mCookTime;
private TextView mServingSize;
private RelativeLayout mRecipeTextSection;
public ViewHolder(View v) {
super(v);
mRecipeName = (TextView) v.findViewById(R.id.recipe_list_recycler_view_recipe_name);
mServingSize = (TextView) v.findViewById(R.id.recipe_list_recycler_view_serving_size);
mPrepTime = (TextView) v.findViewById(R.id.recipe_list_recycler_view_prep_time);
mCookTime = (TextView) v.findViewById(R.id.recipe_list_recycler_view_cook_time);
mRecipeTextSection = (RelativeLayout) v.findViewById(R.id.recycled_item_section_view);
mAddToGroceriesButton = (Button) v.findViewById(R.id.add_to_grocery_list);
}
}
public void add(int position, Recipe item) {
mRecipeSet.add(position, item);
notifyItemInserted(position);
}
public void remove(Recipe item) {
int position = mRecipeSet.indexOf(item);
mRecipeSet.remove(position);
notifyItemRemoved(position);
}
public RecipeListAdapter(ArrayList<Recipe> myRecipeset) {
mRecipeSet = myRecipeset;

how can i implement both functionality scroll and swipe?

Scrollable TextView: Put the TextView as the child of a ScrollView.
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
</ScrollView>
Remember that a ScrollView can only hold ONE object.
For Gestures, look at Detecting Common Gestures
EDIT:
You can also use this line of code in the XML and see if it works (with the textview):
android:scrollbars="vertical"

Put your textview inside scrollview in xml. Then make it "swipeable" programmatically. Stackoverflow is telling me that my answer does not meet their quality standards.

I'm not sure which of these classes I need to be restoring and how I can restore the previous details and images in HomeFragment after clicking back from the detail activity. I would be able to just describe a parent activity in my manifest but the main class holding everything is a fragment and android doesn't let you choose parent fragments! Any ideas or help would be appreciated.

Try to remove initialization of List from declaration.
private List buyersProfiles = new ArrayList();
And make initialization in onCreateView method if List is null.

EditText not working in RecyclerView Adapter. Random Data is displayed on device

Im currently making an app that takes movie name as input from user, after that input a new screen will be displayed showing list items of movie, the list of that movie is shown from "http://www.omdbapi.com/" just like IMDB. On clicking any list item(movie name) details of that movie will be shown in another screen, everything was working fine before getting input, I hard code the movie name before but now i want user to give inout but I think there's a problem in Edit Text I'm unable to get input from user.

You are treating MovieFragment as an activity
Intent intent = new Intent(this, MovieFragment.class);
intent.putExtra(Intent.EXTRA_TEXT, input);
startActivity(intent);
But MovieFragment is a fragment. You need to add/replace the MovieFragment in your activity.
Also, there is no need to setContentView(R.layout.activity_main); again in validateInput()
