Here is the layout code:

Answer 1

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);
    }

CollapsingToolbarLayout with a custom view

Answer 2

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"
            />

Answer 3

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.
