If you want just to include the Toolbar without any scrolling effects you can use Toolbar. But if you want to make some scrolling effects like on the images you need to use AppBarLayout.[![enter image description here][1]][1] [![enter image description here][2]][2]

More [here][3] and [here][4].

The `AppBarLayout` is used to achieve various scrolling behaviors such as collapse, flex space, and quick return.

AppBarLayout is a parent layout of ToolBar and ToolBar is custom ActionBar.
if you want scroll action on the ToolBar so you should write ToolBar into the AppBarLayout,before you will write code for scroll the ToolBar, you must know the NestedScrollBar,it is used to scroll the ToolBar. but you cannot connect NestedScrollBar and ToolBar directly,because ToolBar is child of AppBarLayout and NestedScrollBar is sibling of AppBarLayout, that&#39;s why your Toolbar should in the AppBarlayout then you can connect AppBarlayout and NestedScrollBarLayout for scrolling action on the toolbar.

I have a list of `Integer` `list` and from the `list.stream()` I want the maximum value.

What is the simplest way? Do I need comparator?

I am trying to create custom validation for a model, to check that its `start_date` is before its `end_date` and it is proving near impossible.

Stuff I&#39;ve tried:

- built-in Django validators: none check for this

- writing my own, like so:

    
        def validate_date(self):
           if self.start_date &lt; self.end_date:
                raise serializers.ValidationError(&quot;End date must be after start date.&quot;)


That bit of code I have added to the Serializer class (and then the model), but it does not seem to get called in either location.

I also found [this][1] bit of code that might be of use, but I don&#39;t know how to integrate in my method- it seems that it would work to validate one model attribute, but I need to check between two attributes.

My model:

    class MyModel(models.Model):

        created = models.DateTimeField(auto_now_add=True)
        relation_model = models.ForeignKey(RelationModel, related_name=&quot;mymodels&quot;)
        priority = models.IntegerField(
            validators = [validators.MinValueValidator(0), validators.MaxValueValidator(100)])
        start_date = models.DateField()
    end_date = models.DateField()
    
        @property
        def is_active(self):
            today = datetime.date.today()
            return (today &gt;= self.start_date) and (today &lt;= self.end_date)
    
        def __unicode__(self):
            ...
    
        class Meta:
            unique_together = (&#39;relation_model&#39;, &#39;priority&#39;, &#39;start_date&#39;, &#39;end_date&#39;)

Fyi, all the other validations work!

My serializer:

    class MyModelSerializer(serializers.ModelSerializer):

        relation_model = RelationModelSerializer
        is_active = serializers.Field(source=&#39;is_active&#39;)

        def validate_date(self):
            if self.start_date &gt; self.end_date:
                raise serializers.ValidationError(&quot;End date must be after start date.&quot;)   
 
        class Meta:
            model = MyModel
            fields = (
                &#39;id&#39;, &#39;relation_model&#39;, &#39;priority&#39;, &#39;start_date&#39;, &#39;end_date&#39;, &#39;is_active&#39;
            )

My view:

    class MyModelList(generics.ListCreateAPIView):
        permission_classes = (IsAdminUser,)
        queryset = MyModel.objects.all()
        serializer_class = MyModelSerializer
        ordering = (&#39;priority&#39;)

[DataBinding Guide][1] States

  

      By default, a Binding class will be generated based on the name of the layout 
    file, converting it to Pascal case and suffixing “Binding” to it. 
    The above layout file was activity_main.xml so the generate class was ActivityMainBinding.

 


When will the Binding class , here say ActivityMainBinding, will be generated. I have compile time error. &quot;cannot resolve ActivityMainBinding&quot;.


    ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.main_activity);

Any help is appreciated. Thanks

Android newbie. My processor is AMD, not Intel, so I can&#39;t open the emulator in Android studio. 

This answer has the comment: &#39;You can run the ARM (non Intel) emulator image. From your list, just choose a non Intel emulation.&#39; They don&#39;t explain where this can be found. Any ideas? Thanks

I am trying to figure out what is the issue with updating `RecyclerView`&#39;s Adapter.

After I get a new List of products, I tried to:

1. Update the `ArrayList` from the fragment where `recyclerView` is created, set new data to adapter, and then call `adapter.notifyDataSetChanged()`; it did not work.

2. Create a new adapter, as others did, and it worked for them, but there wasn&#39;t any change for me: `recyclerView.setAdapter(new RecyclerViewAdapter(newArrayList))`

3. Create a method in `Adapter` which updates the data as follows:

        public void updateData(ArrayList&lt;ViewModel&gt; viewModels) {
           items.clear();
           items.addAll(viewModels);
           notifyDataSetChanged();
        }

    Then I call this method whenever I want to update the data list; it did not work.

4. To check if I can modify the recyclerView in any way, and I tried to remove at least an item:

         public void removeItem(int position) {
            items.remove(position);
            notifyItemRemoved(position);
        }

Everything remained as it was.

Here is my Adapter:

    public class RecyclerViewAdapter extends RecyclerView.Adapter&lt;RecyclerViewAdapter.ViewHolder&gt; implements View.OnClickListener {

        private ArrayList&lt;ViewModel&gt; items;
        private OnItemClickListener onItemClickListener;

        public RecyclerViewAdapter(ArrayList&lt;ViewModel&gt; items) {
            this.items = items;
        }


        public void setOnItemClickListener(OnItemClickListener onItemClickListener) {
            this.onItemClickListener = onItemClickListener;
        }

        @Override
        public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_recycler, parent, false);
            v.setOnClickListener(this);
            return new ViewHolder(v);
        }

        public void updateData(ArrayList&lt;ViewModel&gt; viewModels) {
            items.clear();
            items.addAll(viewModels);
            notifyDataSetChanged();
        }
        public void addItem(int position, ViewModel viewModel) {
            items.add(position, viewModel);
            notifyItemInserted(position);
        }

        public void removeItem(int position) {
            items.remove(position);
            notifyItemRemoved(position);
        }


        @Override
        public void onBindViewHolder(ViewHolder holder, int position) {
            ViewModel item = items.get(position);
            holder.title.setText(item.getTitle());
            Picasso.with(holder.image.getContext()).load(item.getImage()).into(holder.image);
            holder.price.setText(item.getPrice());
            holder.credit.setText(item.getCredit());
            holder.description.setText(item.getDescription());

            holder.itemView.setTag(item);
        }


        @Override
        public int getItemCount() {
            return items.size();
        }


        @Override
        public void onClick(final View v) {
            // Give some time to the ripple to finish the effect
            if (onItemClickListener != null) {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        onItemClickListener.onItemClick(v, (ViewModel) v.getTag());
                    }
                }, 0);
            }
        }

        protected static class ViewHolder extends RecyclerView.ViewHolder {
            public ImageView image;
            public TextView price, credit, title, description;

            public ViewHolder(View itemView) {
                super(itemView);
                image = (ImageView) itemView.findViewById(R.id.image);
                price = (TextView) itemView.findViewById(R.id.price);
                credit = (TextView) itemView.findViewById(R.id.credit);
                title = (TextView) itemView.findViewById(R.id.title);
                description = (TextView) itemView.findViewById(R.id.description);
            }
        }

        public interface OnItemClickListener {

            void onItemClick(View view, ViewModel viewModel);

        }
    }

And I initiate `RecyclerView` as follows:

    recyclerView = (RecyclerView) view.findViewById(R.id.recycler);
    recyclerView.setLayoutManager(new GridLayoutManager(getActivity(), 5));
    adapter = new RecyclerViewAdapter(items);
    adapter.setOnItemClickListener(this);
    recyclerView.setAdapter(adapter);

So, how do I actually update adapter data in order to display newly received items?

The issue was that the layout where gridView was looked as follows:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;LinearLayout
        xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        android:orientation=&quot;vertical&quot;
        android:layout_width=&quot;match_parent&quot;
        android:tag=&quot;catalog_fragment&quot;
        android:layout_height=&quot;match_parent&quot;&gt;

        &lt;FrameLayout
            android:orientation=&quot;vertical&quot;
            android:layout_width=&quot;match_parent&quot;
            android:layout_height=&quot;match_parent&quot;&gt;

            &lt;android.support.v7.widget.RecyclerView
                android:id=&quot;@+id/recycler&quot;
                android:layout_width=&quot;match_parent&quot;
                android:layout_height=&quot;match_parent&quot;
                android:clipToPadding=&quot;false&quot;/&gt;

            &lt;ImageButton
                android:id=&quot;@+id/fab&quot;
                android:layout_gravity=&quot;top|end&quot;
                style=&quot;@style/FabStyle&quot;/&gt;

        &lt;/FrameLayout&gt;
    &lt;/LinearLayout&gt;

Then I just removed `LinearLayout` and made `FrameLayout` as the parent layout.

I have a multi-flavored, multi-build-typed android project and I want to integrate the NewRelic plugin. But I have to apply it only for one of the customers, thus only for one product flavor.&lt;br&gt;
NewRelic uses instrumentation and the plugin would generate code in other flavors if I applied the plugin there, and that is not permitted for us.

So my question is: How can I use the `apply plugin: something` command in the gradle file to be applied to only one of my flavors?

Status bar turns white and does not show content behind it

I am looking to add scroll support to more than just a single, scrollable, child view of `CoordinatorLayout` in conjunction with an `AppBarLayout` and `CollapsingToolbarLayout`. When scrolling the `RecyclerView` or the `AppBarLayout` (condensed code below), the app bar and its contents successfully scroll and collapse. However, when attempting to initiate a scroll event on the `LinearLayout` above the `RecyclerView`, nothing happens because the `LinearLayout` does not know to scroll or collapse the view.

The goal is to have the `LinearLayout` act as a sticky header to the `RecyclerView` and footer to the `AppBarLayout` and receive the same scrolling behavior as the `RecyclerView`, similar to [Spotify&#39;s shuffle play/available offline header][1]. In fact, it would be great if the `appbar_scrolling_view_behavior` `layout_behavior` could be applied to the `LinearLayout` similarly to the `RecyclerView`, but I imagine that the behavior is ignored on non-scrollable views. Is anyone aware of a workaround for this that does not require implementing the `LinearLayout` view as a row in the `RecyclerView`?

Add app bar scrolling view behavior to multiple views in CoordinatorLayout

I have to use `TextInputLayout` of design support library in my project. I want to give space between `hint` and `EditText` in `TextInputLayout`. I set margin and padding in `TextInputLayout` and even inside `EditText` but both are not work.So how to solve this issue. Here i attach screen shot and my coding.
    
    ==============================Style=================================
  
    &lt;style name=&quot;TextHint&quot; parent=&quot;Base.TextAppearance.AppCompat&quot;&gt;
        &lt;item name=&quot;android:textSize&quot;&gt;18sp&lt;/item&gt;
        &lt;item name=&quot;android:textColor&quot;&gt;@color/green&lt;/item&gt;
    &lt;/style&gt;



    =============================XML===================================  
    &lt;android.support.design.widget.TextInputLayout
        android:layout_width=&quot;match_parent&quot;
        app:hintTextAppearance=&quot;@style/TextHint&quot;
        android:layout_marginTop=&quot;10dp&quot;
        android:layout_marginLeft=&quot;30dp&quot;
        android:layout_marginRight=&quot;30dp&quot;
        android:layout_height=&quot;wrap_content&quot;&gt;
    &lt;EditText
        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;50dp&quot;
        android:id=&quot;@+id/edttxtEmailAddress&quot;
        android:singleLine=&quot;true&quot;
        android:hint=&quot;@string/enter_valid_email&quot;
        android:paddingLeft=&quot;20dp&quot;
        android:textSize=&quot;20sp&quot;
        android:background=&quot;@drawable/rounded_common&quot;/&gt;
    &lt;/android.support.design.widget.TextInputLayout&gt;

TextInputLayout :How to give padding or margin to hint?

I have the following layout:

    &lt;android.support.design.widget.CoordinatorLayout
        android:id=&quot;@+id/main_content&quot;
        xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        xmlns:app=&quot;http://schemas.android.com/apk/res-auto&quot;
        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;match_parent&quot;&gt;
    
        &lt;android.support.design.widget.AppBarLayout
            android:id=&quot;@+id/appBar&quot;
            android:layout_width=&quot;match_parent&quot;
            android:layout_height=&quot;wrap_content&quot;
            android:theme=&quot;@style/ThemeOverlay.AppCompat.ActionBar&quot;&gt;
    
            &lt;android.support.v7.widget.Toolbar
                android:id=&quot;@+id/toolbar&quot;
                android:layout_width=&quot;match_parent&quot;
                android:layout_height=&quot;?attr/actionBarSize&quot;
                android:background=&quot;?attr/colorPrimary&quot;
                app:layout_scrollFlags=&quot;scroll|enterAlways&quot;
                app:popupTheme=&quot;@style/ThemeOverlay.AppCompat.Light&quot;/&gt;
    
        &lt;/android.support.design.widget.AppBarLayout&gt;
    
        &lt;FrameLayout
            android:id=&quot;@+id/content&quot;
            android:layout_width=&quot;match_parent&quot;
            android:layout_height=&quot;match_parent&quot;
            /&gt;
    &lt;/android.support.design.widget.CoordinatorLayout&gt;


I add `Fragment`s into the `FrameLayout`, replacing them. One of my `Fragment`s is a list, which has the following layout:

    &lt;android.support.v7.widget.RecyclerView
        xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        xmlns:app=&quot;http://schemas.android.com/apk/res-auto&quot;
        android:id=&quot;@+id/recyclerView&quot;
        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;match_parent&quot;
        app:layout_behavior=&quot;@string/appbar_scrolling_view_behavior&quot;/&gt;

My problem here that the **toolbar is drawn over the list**. I tried to solve that by wrapping the content of the `CoordinatorLayout` into a `LinearLayout`, that solved the overdraw, but that way the appbar scrolling behavior no longer work.

Any help is much appreciated!
