Toolbar Not Scrolling When Using Collapsing Toolbar Effect
Solution 1:
I suppose that the view with app:layout_behavior="@string/appbar_scrolling_view_behavior"
has to be scrollable vertically, which ViewPager
is not. I am not quite sure whether wrapping the ViewPager
into some ScrollView
would help. Most probably it would cause some problems with touch event handling. If the page within your ViewPager
is scrollable, you should set the app:layout_behavior
directly to its scrollable view but I am not sure this would work as expected either. The collapsing toolbar effect is not meant to work this way and it is not yet perfect even when used as intended.
Solution 2:
Use design support library http://android-developers.blogspot.in/2015/05/android-design-support-library.html
include this in build.gradle
compile'com.android.support:design:22.2.0'compile'com.android.support:appcompat-v7:22.2.+'
for recycler view include this also
compile'com.android.support:recyclerview-v7:22.2.0'

Your activity should extend AppCompatActivity
publicclassYourActivityextendsAppCompatActivity {
@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_layout);
//set toolbarToolbartoolbar= (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
}
Your app theme should be like this
<resources><!-- Base application theme. --><stylename="AppTheme"parent="Theme.AppCompat.NoActionBar"></style></resources>
