```

You will see on Android Studio Preview :

![alt preview](https://raw.github.com/florent37/MaterialViewPager/master/screenshots/preview_small.png)

To get a beautiful screen and enable preview, you theme may follow

```xml
<style name="AppBaseTheme" parent="@style/Theme.AppCompat.Light">
</style>

<style name="AppTheme" parent="AppBaseTheme">

   <item name="android:textColorPrimary">@android:color/white</item>
   <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
   <item name="android:windowTranslucentStatus" tools:targetApi="21">true</item>

   <item name="android:windowContentOverlay">@null</item>
   <item name="windowActionBar">false</item>
   <item name="windowNoTitle">true</item>

   <!-- Toolbar Theme / Apply white arrow -->
   <item name="colorControlNormal">@android:color/white</item>
   <item name="actionBarTheme">@style/AppTheme.ActionBarTheme</item>

   <!-- Material Theme -->
   <item name="colorPrimary">@color/colorPrimary</item>
   <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
   <item name="colorAccent">@color/accent_color</item>

   <item name="android:navigationBarColor" tools:targetApi="21">@color/navigationBarColor</item>
   <item name="android:windowDrawsSystemBarBackgrounds" tools:targetApi="21">true</item>

</style>

<style name="AppTheme.ActionBarTheme" parent="@style/ThemeOverlay.AppCompat.ActionBar">
    <!-- White arrow -->
    <item name="colorControlNormal">@android:color/white</item>
</style>

<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="spinBars">true</item>
    <item name="color">@color/drawerArrowColor</item>
</style>
```

# Retrieve the MaterialViewPager

You can use MaterialViewPager as an usual Android View, and get it by findViewById

```java
public class MainActivity extends ActionBarActivity {

    private MaterialViewPager mViewPager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mViewPager = (MaterialViewPager) findViewById(R.id.materialViewPager);
    }
}
```

# Customisation

First choose your color and height
```xml
<com.github.florent37.materialviewpager.MaterialViewPager
        android:id="@+id/materialViewPager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        ...
        app:viewpager_color="@color/colorPrimary"
        app:viewpager_headerHeight="200dp"
        ...
        />
```

## Set your logo

```xml
<com.github.florent37.materialviewpager.MaterialViewPager
        ...
        app:viewpager_logo="@layout/header_logo" <-- look custom logo layout
        app:viewpager_logoMarginTop="100dp" <-- look at the preview
        ...
        />
```

### Titlebar Logo

[![Video](http://share.gifyoutube.com/ygbqnA.gif)](http://youtu.be/82gvoUqXb_I)

Your logo's layout must
* layout_height="@dimen/materialviewpager_logoHeight"

**header_logo.xml**
```xml
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/logo_white"
    android:layout_width="200dp"
    android:layout_height="@dimen/materialviewpager_logoHeight"
    android:fitsSystemWindows="true"
    android:adjustViewBounds="true"
    android:layout_centerHorizontal="true"
    android:src="@drawable/logo_white" />
```

```xml
<com.github.florent37.materialviewpager.MaterialViewPager`
        ...
        app:viewpager_hideLogoWithFade="false"
        ...
        />

```

### Fading Logo

[![Video](http://share.gifyoutube.com/KYb0D4.gif)](http://youtu.be/9laniARQdqg)

**header_logo.xml**
```xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="80dp"
    android:layout_height="80dp"
    android:layout_centerHorizontal="true"
    android:background="@drawable/circle">

    <ImageView
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:fitsSystemWindows="true"
        android:adjustViewBounds="true"
        android:layout_gravity="center"
        android:src="@drawable/flying" />
</FrameLayout>
```

```xml
<com.github.florent37.materialviewpager.MaterialViewPager`
        ...
        app:viewpager_hideLogoWithFade="true"
        ...
        />
```

## Toolbar Animation

## Hide Logo and Toolbar

[![Video](http://share.gifyoutube.com/y5V8JX.gif)](http://youtu.be/3ElFoqVKxag)

```xml
<com.github.florent37.materialviewpager.MaterialViewPager`
        ...
        app:viewpager_hideToolbarAndTitle="true"
        ...
        />
```

### Sticky Toolbar

[![Video](http://share.gifyoutube.com/yo2oJn.gif)](http://youtu.be/3ElFoqVKxag)

```xml
<com.github.florent37.materialviewpager.MaterialViewPager`
        ...
        app:viewpager_hideToolbarAndTitle="false"
        ...
        />
```

### Transparent Toolbar

[![Video](http://share.gifyoutube.com/ywbP8k.gif)](https://youtu.be/jUVO2cozQHQ)

```xml
<com.github.florent37.materialviewpager.MaterialViewPager`
        ...
        app:viewpager_transparentToolbar="true"
        ...
        />
```

## Header Layout

You can replace the header

```xml
<com.github.florent37.materialviewpager.MaterialViewPager`
        ...
        app:viewpager_header="@layout/myHeader"
        ...
        />
```

### Moving Header

Or use the default header, with a KenBurns animation

```xml
<com.github.florent37.materialviewpager.MaterialViewPager`
        ...
        app:viewpager_animatedHeaderImage="true"
        ...
        />
```

### Static Header

Or simply use an ImageView as header

```xml
<com.github.florent37.materialviewpager.MaterialViewPager`
        ...
        app:viewpager_animatedHeaderImage="false"
        ...
        />
```

## Custom Tab Bar

You can set you own tab bar, by default I provided 2 implementations

### Standard

[![Video](http://share.gifyoutube.com/KdnoZX.gif)](http://youtu.be/VRinfxgewNE)

```xml
<com.github.florent37.materialviewpager.MaterialViewPager`
        ...
        app:viewpager_pagerTitleStrip="@layout/material_view_pager_pagertitlestrip_standard"
        ...
        />
```

### News Stand

[![Video](http://share.gifyoutube.com/KeboLp.gif)](http://youtu.be/MBzK2s7HU1A)

```xml
<com.github.florent37.materialviewpager.MaterialViewPager`
        ...
        app:viewpager_pagerTitleStrip="@layout/material_view_pager_pagertitlestrip_newstand"
        ...
        />
```

### Or create your own tab bar

Create your own layout using a PagerSlidingTabStrip

**my_tabs.xml**
```xml
<com.astuetz.PagerSlidingTabStrip
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@id/materialviewpager_pagerTitleStrip"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:pstsPaddingMiddle="true"
    app:pstsDividerPadding="20dp"
    app:pstsIndicatorColor="#FFF"
    app:pstsIndicatorHeight="2dp"
    app:pstsShouldExpand="true"
    app:pstsTabPaddingLeftRight="10dp"
    app:pstsTabTextAllCaps="true"
    tools:background="#A333"
     />
```

**Don't forget to give it id="@id/materialviewpager_pagerTitleStrip"**

```xml
<com.github.florent37.materialviewpager.MaterialViewPager
        ...
        app:viewpager_pagerTitleStrip="@layout/my_tabs"
        ...
        />
```

# Animate Header

[![Video](http://share.gifyoutube.com/yABkgW.gif)](http://youtu.be/90gKwEL1j2I )

Simply add a listen to the ViewPager

```java
mViewPager.setMaterialViewPagerListener(new MaterialViewPager.Listener() {
            @Override
            public HeaderDesign getHeaderDesign(int page) {
                switch (page) {
                    case 0:
                        return HeaderDesign.fromColorResAndUrl(
                                R.color.blue,
                                "http://cdn1.tnwcdn.com/wp-content/blogs.dir/1/files/2014/06/wallpaper_51.jpg");
                    case 1:
                        return HeaderDesign.fromColorResAndUrl(
                                R.color.green,
                                "https://fs01.androidpit.info/a/63/0e/android-l-wallpapers-630ea6-h900.jpg");
                    case 2:
                        return HeaderDesign.fromColorResAndUrl(
                                R.color.cyan,
                                "http://www.droid-life.com/wp-content/uploads/2014/10/lollipop-wallpapers10.jpg");
                    case 3:
                        return HeaderDesign.fromColorResAndUrl(
                                R.color.red,
                                "http://www.tothemobile.com/wp-content/uploads/2014/07/original.jpg");
                }

                //execute others actions if needed (ex : modify your header logo)

                return null;
            }
        });
```

Available

```java
HeaderDesign.fromColorAndUrl(Color.BLUE,"http:...);
HeaderDesign.fromColorResAndUrl(R.color.blue,"http:...);
HeaderDesign.fromColorAndDrawable(Color.BLUE,myDrawable);
HeaderDesign.fromColorResAndDrawable(R.color.blue,myDrawable);
```

# Toolbar

```java
Toolbar toolbar = mViewPager.getToolbar();

if (toolbar != null) {
     setSupportActionBar(toolbar);

     ActionBar actionBar = getSupportActionBar();
     actionBar.setDisplayHomeAsUpEnabled(true);
     actionBar.setDisplayShowHomeEnabled(true);
     actionBar.setDisplayShowTitleEnabled(true);
     actionBar.setDisplayUseLogoEnabled(false);
     actionBar.setHomeButtonEnabled(true);
}
```

# ViewPager

```java
ViewPager viewPager = mViewPager.getViewPager();
viewPage.setAdapter(...);

//After set an adapter to the ViewPager
mViewPager.getPagerTitleStrip().setViewPager(mViewPager.getViewPager());
```

# RecyclerView

```java
mRecyclerView.addItemDecoration(new MaterialViewPagerHeaderDecorator());
mRecyclerView.setAdapter(yourAdapter);
```

# ScrollView

The ScrollView must be an NestedScrollView`
```java
MaterialViewPagerHelper.registerScrollView(getActivity(), mScrollView, null);
```

And include @layout/material_view_pager_placeholder` as first child

```xml
<android.support.v4.widget.NestedScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/scrollView"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <include layout="@layout/material_view_pager_placeholder"/>

        ...your content...

    </LinearLayout>
</android.support.v4.widget.NestedScrollView>
```
