I want something like this:
I have the following now:
With the following XML:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_height="130dp"
android:layout_width="match_parent">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:toolbarId="#+id/toolbar"
app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed"
app:contentScrim="?attr/colorPrimary">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/book_detail">
</FrameLayout>
</android.support.v4.widget.NestedScrollView>
<android.support.design.widget.FloatingActionButton
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:src="#android:drawable/ic_input_add"
android:layout_margin="16dp"
android:clickable="true"
android:focusable="true"
app:layout_anchor="#id/appbar"
app:layout_anchorGravity="bottom|end"/>
</android.support.design.widget.CoordinatorLayout>
But I have some problems:
The Title is on top instead of bottom
There's something like a separator on top
I'm using a coordinator now, but I don't need a collapsing toolbar, so I think that there must be another solution maybe. How can I solve this?
Let's first start by making the toolbar taller. I think what you're looking for is CollapingToolbarLayout
To use the CollapsingToolbarLayout you have to change your ConstraintLayout to CoordinatorLayout.
Then you have to create an AppBarLayout to hold the CollapsingToolbarLayout and the Toolbar.
Then to make the floating button in that place you have to anchor it to the AppBarLayout created earlier like below:
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top|end"
android:layout_margin="16dp"
app:layout_anchor="#id/app_bar"
app:layout_anchorGravity="bottom|end"
android:clickable="true"
android:src="#drawable/message"
android:focusable="true"
app:elevation="30dp"/>
That way it will be anchored to the AppBarLayout so it will go up and down as the AppBarLayout goes up or down.
EDIT #1 :
To remove the title from the top and remove the separator you have to set your activity's theme to NoActionBar. In your AndroidManifest.xml file go to your activity and change its code to the following:
<activity
android:name="YOUR_ACTIVITY_PATH.BookDetailActivity"
android:theme="#style/AppTheme.NoActionBar" />
This way the activity will be declared without an action bar which means no separator and no title.
Then to add the title to the bottom you just have to set the title of the CollapsingToolbarLayout to the text you want.
You can set it in the xml with app:title="YOUR_TITLE" attribute or you can set it programmatically by calling the function setTitle("YOUR_TITLE") for your CollapsingToolbarLayout variable .
Here is what the full code could look like:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

</android.support.design.widget.CoordinatorLayout>
EDIT 2:
In your activity set your action bar by this :
setSupportActionBar(YOUR_TOOLBAR_VARIABLE) then you can use getSupportActionBar().setDisplayHomeAsUpEnabled(true)
Note that the toolbar should be the id of this one:
android.support.v7.widget.Toolbar so in our case the toolbar with the id toolbar
Use this layout
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="192dp">
<android.support.design.widget.CollapsingToolbarLayout

android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" />

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
app:layout_anchor="#id/app_bar_layout"
app:layout_anchorGravity="bottom|right|end" />
The use this class for action of FAB
public class FlexibleSpaceExampleActivity extends AppCompatActivity
implements AppBarLayout.OnOffsetChangedListener {
private static final int PERCENTAGE_TO_SHOW_IMAGE = 20;
private View mFab;
private int mMaxScrollSize;
private boolean mIsImageHidden;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_flexible_space);
mFab = findViewById(R.id.flexible_example_fab);
Toolbar toolbar = (Toolbar) findViewById(R.id.flexible_example_toolbar);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override public void onClick(View v) {
onBackPressed();
}
});
AppBarLayout appbar = (AppBarLayout) findViewById(R.id.flexible_example_appbar);
appbar.addOnOffsetChangedListener(this);
}
#Override
public void onOffsetChanged(AppBarLayout appBarLayout, int i) {
if (mMaxScrollSize == 0)
mMaxScrollSize = appBarLayout.getTotalScrollRange();
int currentScrollPercentage = (Math.abs(i)) * 100
/ mMaxScrollSize;
if (currentScrollPercentage >= PERCENTAGE_TO_SHOW_IMAGE) {
if (!mIsImageHidden) {
mIsImageHidden = true;
ViewCompat.animate(mFab).scaleY(0).scaleX(0).start();
/**
* Realize your any behavior for FAB here!
**/
}
}
if (currentScrollPercentage < PERCENTAGE_TO_SHOW_IMAGE) {
if (mIsImageHidden) {
mIsImageHidden = false;
ViewCompat.animate(mFab).scaleY(1).scaleX(1).start();
/**
* Realize your any behavior for FAB here!
**/
}
}
}
public static void start(Context c) {
c.startActivity(new Intent(c, FlexibleSpaceExampleActivity.class));
}
}
There are some Github Implementation to develope this view and many other

I'm using AppBarLayout with CollapsingToolbarLayout that can change its height when the user scroll screen. Also, I have fragments under AppBarLayout. One of the fragment has a custom bottom navigation bar 1. And when CollapsingToolbarLayout is fully opened I can't see Bottom Nav Bar for this fragment. I want to pin it somehow.2
I tried to use layout_behavior="#string/appbar_scrolling_view_behavior" not on fragment but on view in this fragment but it didn't work.
Main.xml
<android.support.v4.widget.DrawerLayout>
<android.support.design.widget.CoordinatorLayout>

</android.support.v4.widget.DrawerLayout>
some_fragment.xml
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--This view I want to pin-->
<View
android:id="#+id/bottom_navigation_bar"
android:layout_width="match_parent"
android:layout_height="63dp"
android:layout_alignParentBottom="true"
android:orientation="vertical">
</View>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/bottom_navigation_bar"
android:layout_alignParentTop="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</RelativeLayout>
I managed to find some strange solution for this. This code is for Xamarin Android C#. I just made the bottom margin according to AppBarLayout offset
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
SetContentView(Resource.Layout.home_view);
var appBar = FindViewById<AppBarLayout>(Resource.Id.app_bar);
appBar.AddOnOffsetChangedListener(this);
}
public void OnOffsetChanged(AppBarLayout appBarLayout, int verticalOffset)
{
var minHeight = Resources.GetDimension(Resource.Dimension.app_bar_min_height);
var fragment = SupportFragmentManager.FindFragmentById(Resource.Id.content_frame);
if (fragment is DashboardView) {
var layout = fragment.View.FindViewById<RelativeLayout>(Resource.Id.dashboard_layout);
var param = new FrameLayout.LayoutParams(LayoutParams.MatchParent, LayoutParams.WrapContent);
param.SetMargins(0, 0, 0, verticalOffset + (int)minHeight);
layout.LayoutParameters = param;
}
}
I'm trying to animate CollapsingToolbarLayout title with scroll.My goal is to animate text center position ,right now text animate left side.Here is a my xml code
My goal is to receive like this result.I would to change CollapsingToolbarLayout text with toolbar text in center size and also I would to change toolbar background color with scroll position .
How I can solve this problem?
thanks

Try this for any changes in to CollapsingToolbarLayout..
make style..
<style name="coll_toolbar_title">
<item name="android:textColor">#color/primary</item>
<item name="android:textSize">#dimen/_13sdp</item>
</style>
then set.. using id..
collapseLayout.setCollapsedTitleTextAppearance(R.style.coll_toolbar_title)
mange scrolling to change here you can change toolbar background ...
appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
boolean isShow = true;
int scrollRange = -1;
#Override
public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
if (scrollRange == -1) {
}
if (scrollRange + verticalOffset == 0) {
// expend
collapsingToolbarLayout.setTitle("Title");
isShow = true;
} else if(isShow) {
// collepse
collapsingToolbarLayout.setTitle(" ");//carefull there should a space between double quote otherwise it wont work
isShow = false;
}
}
});

How can use an icon with the title text?
You may try the following
Reference for Co-Ordinator Layout
Now inside your MainActivity.java
private void handleToolbarTitleVisibility(float percentage) {
if (percentage >= PERCENTAGE_TO_SHOW_TITLE_AT_TOOLBAR) {
if(!mIsTheTitleVisible) {
startAlphaAnimation(textviewTitle, ALPHA_ANIMATIONS_DURATION, View.VISIBLE);
toolbar.setAlpha(0.9f);
toolbar.setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.Primary)));
mIsTheTitleVisible = true;
}
}
else {
if (mIsTheTitleVisible) {
startAlphaAnimation(textviewTitle, ALPHA_ANIMATIONS_DURATION, View.INVISIBLE);
toolbar.setBackgroundDrawable(new ColorDrawable(getResources().getColor(android.R.color.transparent)));
mIsTheTitleVisible = false;
}
}
}
Note: Keep the toolbars background transparent when expanded.
You can take reference from this example:-
android ParallaxHeaderViewPager
May be this solve your problem :
You can position the expanded title wherever you want by using these CollapsingToolbarLayout attributes:
app:expandedTitleGravity default is bottom|left -or- bottom|start
app:expandedTitleMargin
app:expandedTitleMarginBottom
app:expandedTitleMarginStart
app:expandedTitleMarginEnd
Code for layout File :
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapse_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
android:fitsSystemWindows="true">
<ImageView
android:id="#+id/bgheader"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:fitsSystemWindows="true"
android:background="#drawable/sunflowerpic"
app:layout_collapseMode="pin" />
<android.support.v7.widget.Toolbar
android:id="#+id/MyToolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="parallax" />
</android.support.design.widget.CollapsingToolbarLayout>
Then in your java file SetTitle:
CollapsingToolbarLayout collapsingToolbar =
(CollapsingToolbarLayout) findViewById(R.id.collapse_toolbar);
collapsingToolbar.setTitle("Title");
Add icon to Top corner :
use app:layout_collapseMode="pin" with ImagView. For e.g.
<ImageView
android:id="#+id/someImage"
android:layout_width="56dp"
android:layout_height="wrap_content"
android:src="#drawable/someDrawable"
android:padding="16dp"
android:layout_gravity="top|end"
app:layout_collapseMode="pin"
/>
Reference to this link Collapsing Toolbar Example
I suggest you to try Childs and dependencies
public boolean onDependentViewChanged(
CoordinatorLayout parent,
CircleImageView avatar,
View dependency) {
modifyAvatarDependingDependencyState(avatar, dependency);
}
private void modifyAvatarDependingDependencyState(
CircleImageView avatar, View dependency) {
// avatar.setY(dependency.getY());
// avatar.setBlahBlat(dependency.blah / blah);
}
http://www.devexchanges.info/2016/03/android-tip-custom-coordinatorlayout.html
CollapsingToolbarLayout with a custom view
In Kotlin
private fun handleToolbarTitleVisibility(percentage: Float) {
if (percentage >= PERCENTAGE_TO_SHOW_TITLE_AT_TOOLBAR) {
if (!mIsTheTitleVisible) {
startAlphaAnimation(textviewTitle, ALPHA_ANIMATIONS_DURATION, View.VISIBLE)
toolbar.alpha = 0.9f
toolbar.setBackgroundDrawable(ColorDrawable(resources.getColor(R.color.Primary)))
mIsTheTitleVisible = true
}
} else {
if (mIsTheTitleVisible) {
startAlphaAnimation(textviewTitle, ALPHA_ANIMATIONS_DURATION, View.INVISIBLE)
toolbar.setBackgroundDrawable(ColorDrawable(resources.getColor(android.R.color.transparent)))
mIsTheTitleVisible = false
}
}
}
I'm trying to show my FloatingActionButton on top of the SnackBar but I just can't make it as I have done on other screens. My current layout is this one:
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="#dimen/toolbar_elevation"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/AppTheme.ToolbarPopUp"
app:theme="#style/AppTheme.Toolbar"/>
<android.support.design.widget.TabLayout
android:id="#+id/sliding_tabs"
style="#style/Feed.TabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="4dp"/>
<android.support.design.widget.CoordinatorLayout
android:id="#+id/coordinator_fab"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
style="#style/FloatingActionButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:src="#drawable/ic_start"
app:backgroundTint="#color/h19_green"
app:elevation="6dp"
app:pressedTranslationZ="12dp"/>
</android.support.design.widget.CoordinatorLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/navdrawer"/>
</android.support.v4.widget.DrawerLayout>
And my Snackbar code is this one:
#Override
public void alertNoInternetConnection() {
CoordinatorLayout coordinatorLayout = ButterKnife.findById(getActivity(), R.id.coordinator_fab);
Snackbar.make(coordinatorLayout, R.string.connection_offline, Snackbar.LENGTH_INDEFINITE).show();
}
How should I reorganize my layout so that when I display the Snackbar, the Floating Action Button hovers above it?
I was looking quite long for the answer, and finally I've found the solution which worked for me:
FloatingActionButton must be inside CoordinatorLayout
Snackbar should receive FloatingActionButton as it's View argument
Layout:
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.FloatingActionButton
android:id="#+id/fabAdd"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:src="#mipmap/ic_create_white_48dp"
/>
</android.support.design.widget.CoordinatorLayout>
Code:
FloatingActionButton fabAdd = (FloatingActionButton)findViewById(R.id.fabAdd);
Snackbar.make(fabAdd, "Record was removed.", Snackbar.LENGTH_SHORT).show();
Try adding this to your FAB:
app:layout_anchor="#id/coordinator_fab"
app:layout_anchorGravity="bottom|right"
and remove:
android:layout_gravity="bottom|end"

android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="#dimen/fab_margin"
android:src="#drawable/ic_done" />
</android.support.design.widget.CoordinatorLayout>
<include layout="#layout/navdrawer"/>
</android.support.v4.widget.DrawerLayout>
And then, to show the Snackbar correctly:
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Here's a Snackbar", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
The problem is that according to the google guidelines you should not display the FAB above the Snackbar you should swipe the FAB and display the Snack bar below it
check this link :

this worked for me.
<android.support.design.widget.CoordinatorLayout
android:id="#+id/rootLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.design.widget.FloatingActionButton
... />
fabBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Snackbar.make(rootLayout, "Hello. I am Snackbar!",
Snackbar.LENGTH_SHORT)
.setAction("Undo", new View.OnClickListener() {
#Override
public void onClick(View v) {
}
})
.show();
}
});
I am using the new android design CollapsingToolbarLayout. However, I am unable to get the menu to appear. Also, the homeasup indicator does not appear.
Can someone point me in the right direction? Or is this simply not possible?
EDIT
So, I finally got my laptop back. Here is the code.
The Activity
public class CheeseDetailActivity extends AppCompatActivity {
public static final String EXTRA_NAME = "cheese_name";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detail);
Intent intent = getIntent();
final String cheeseName = intent.getStringExtra(EXTRA_NAME);
final Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
CollapsingToolbarLayout collapsingToolbar =
(CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
collapsingToolbar.setTitle(cheeseName);
loadBackdrop();
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
finish();
return true;
}
return super.onOptionsItemSelected(item);
}
private void loadBackdrop() {
final ImageView imageView = (ImageView) findViewById(R.id.backdrop);
Glide.with(this).load(Cheeses.getRandomCheeseDrawable()).centerCrop().into(imageView);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_player, menu);
return true;
}
}
The Layout
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingTop="24dp">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="#dimen/card_margin">
<LinearLayout

android:layout_width="match_parent"
android:layout_height="wrap_content">

</LinearLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>
The menu
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto" >
<item android:id="#+id/action_settings" android:title="#string/action_settings"
android:orderInCategory="100" app:showAsAction="ifRoom" />
</menu>
As we can see, there is no overflow, nothing. But when I press the physical menu button, the menu pops up fine.
So, I guess I was really really dumb. I used the wrong margin for the toolbar. android:layout_marginTop="#dimen/toolbar_top_margin"
The margin was supposed to be -48dp, but I was using 48dp.
I had this in my dimens. I forgot to change to toolbar_top_margin_neg after I refactored.
<dimen name="toolbar_top_margin">48dp</dimen>
<dimen name="toolbar_top_margin_neg">-48dp</dimen>
