How can put a text at the center in CollapsingToolbarLayout and Toolbar? - android

I have a title on the left side in a Toolbar and in a CollapsingToolbarLayout. I want to move it to the center horizontally.
Please help me.
Pictures of my current layout and what I want to achieve:
Code:
<android.support.design.widget.CoordinatorLayout
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/coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.sagar.materialdesigndemo.CollapsingToolbarFragment">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />

<ImageView
android:id="#+id/flexible_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/backmain"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax"/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:titleTextAppearance="#style/ToolbarTitleStyle"
android:layoutDirection="rtl"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>


Set this parameter in your CollapsingToolbarLayout
app:expandedTitleGravity="center_horizontal"


To achieve this, you can get reference to the collapsing toolbar from the corresponding Java class and set the gravity of your title:
CollapsingToolbarLayout collapsingToolbar = (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
//now that you have access to your toolbar, set the directions.
collapsingToolbar.setExpandedTitleGravity(Gravity.CENTER_HORIZONTAL);
collapsingToolbar.setCollapsedTitleGravity(Gravity.CENTER_HORIZONTAL);

How to make Toolbar and TabLayout still visible even when CollapsingToolbarLayout is collapsed?

How to make Toolbar and TabLayout still visible even when CollapsingToolbarLayout is collapsed?
For example, i have a CollapsingToolbarLayout with app:contentScrim animation that contains a Toolbar, ImageView and TabLayout but i want to hide the ImageView when scrolling, but still show the Toolbar and TabLayout inside the CollapsingToolbarLayout even when i swipe up and collapse the view.
I want the Toolbar and TabLayout background to animate into a transparent color when expanding the CollapsingToolbarLayout, and should animate into a solid color as specified by app:contentScrim when collapsing the view.
I'm trying to achieve such in the image:

Collapsing Toolbar Layout with Custom Toolbar

I've been experimenting with CollapsingToolbarLayout in Android. I am trying to change the shape of the Toolbar when it's collapsed. And like this when collapsed.
I want the Toolbar to look something like this when collapsed. I can do it to a normal Toolbar when it's not in a CollapsingToolbarLayout by creating a custom background for it as shown above. But I'm not able to set it to the toolbar in CollapsingToolbarLayout as setting a background simply leads it to showing up in the expanded view and then shifting upwards when in collapsed form.
Any idea how this can be implemented?

How to not completely collapse CollapsingToolbarLayout programmatically?

I have CollapsingToolbarLayout in AppBarLayout. Inside CollapsingToolbarLayout i have Toolbar with app:layout_collapseMode="pin".
And I have RecyclerView. And when I scroll RecyclerView my CollapsingToolbarLayout at first collapse to size of Toolbar. Then it collapse completely.
To show behavior I made gif:
And I have 3 states of CollapsingToolbarLayout:
1) Completely expanded
2) Collapsed to toolbar size
3) Completely Collapsed
If I use method setExpanded of CollapsingToolbarLayout i can Completely Collapsed and Completely Expanded state.
And I wonder how to programmatically collapse CollapsingToolbarLayout to toolbar size (I show it in screenshot Collapsed to toolbar size).
My layout:

Use can use app:layout_scrollFlags="scroll|exitUntilCollapsed"
or
app:layout_scrollFlags="scroll|exitUntilCollapsed|snap"
inside your <android.support.design.widget.CollapsingToolbarLayout

JAVA:
CollapsingToolbarLayout collapsingToolbar =
(CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
collapsingToolbar.setTitle("Title");
It shows me this on android studio:
But when I run it, it just shows me this:
I've even tried to use android.support.v4.widget.NestedScrollView instead of ScrollView but it didn't work either.
Any idea what I'm doing wrong ???

Change the height of NestedScrollView to Wrap_content instead of match_parent, it is occupyig entire screen. Hope that works for you.

Collapsible Toolbar Android

I try to implement Collapsible toolbar feature in my app.
I followed all instructions - wrapped everything in Coordinator Layout, used AppBarLayout but the Toolbar doesn't collapse on scroll...
My layout code:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/lib/com.app.chasebank"
android:id="#+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".AddItemsActivity">
<android.support.v7.widget.RecyclerView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="20dp"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
</android.support.v7.widget.RecyclerView>
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="180dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark">
<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.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
And my Activity code looks like this:
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
CollapsingToolbarLayout collapsingToolbar =(CollapsingToolbarLayout)findViewById(R.id.collapse_toolbar);
collapsingToolbar.setTitle("Buy");
I don't understand - why it doesn't collapse and looks like "pinned" on the screen...
Will appreciate any advice/ help!

Put RecyclerView after AppBarLayout

Try this one:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/lib/com.app.chasebank"
android:id="#+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".AddItemsActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="180dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapse_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
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"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="20dp"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
</android.support.v7.widget.RecyclerView>
</android.support.design.widget.CoordinatorLayout>

Put recycler View after AppBarLayout and use ** app:layout_collapseMode="pin"** in toolbar instead of app:layout_scrollFlags="scroll|enterAlways".
