Menu
I'm working on building a coordinator layout that is made up of a toolbar, a relative layout that is to hide on scroll, a layout that is static always above the scrollable list, and a RecyclerView.
I currently have it laid out as I want it to, as seen here:
This next image is what it looks like once I scroll the whole way up the recycler view.
So my orange view hides as I want it to, which is perfect. The only step i'm missing is moving the "Title 1" textview into becoming the title of the toolbar. I've seen examples where they have done something kind of similar with an image, but haven't been able to duplicate it yet with a custom behavior. I'm assuming thats what this will take?
Does anyone have any advice on if my layout needs to change to make this possible, and any advice for a custom behavior if that is what this will take?

EDIT:
I've got a little bit of progress made. I think I have the layout how I want, and i've got a behavior started. I am able to move the TextView, but it is getting lost behind the toolbar. I want it to go on top of the toolbar. My goal is to move the title from the yellow block into the green block.
Do I need to adjust my layout so make it possible for the textview to appear on top of the title bar?

If you want to add a view to your Toolbar then you have to add it inside Toolbar as a child, and not a child of the include. If you only want to show this TextView on one Activity then set TextView visibility to GONE by default and change it to VISIBLE inside your Activity where you want to show it.
CoordinatorLayout is a super-powered FrameLayout . CoordinatorLayout is intended for two primary use cases: As a top-level application decor or chrome layout. As a container for a specific interaction with one or more child views.
Set The Text of The TextView You can set the text to be displayed in the TextView either when declaring it in your layout file, or by using its setText() method. The text is set via the android:text attribute. You can either set the text as attribute value directly, or reference a text defined in the strings.
My goal is to move the title from the yellow block into the green block.
As your goal is to set the Title from the yellow block into the green there is no need to move Textview in yellow block you can set Title in yellow block with setTitle property of Toolbar.
setCollapseMode with Toolbar you can set it to COLLAPSE_MODE_OFF/COLLAPSE_MODE_PARALLAX/COLLAPSE_MODE_PIN
More Detail on CollapseMode
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"
app:layout_collapseMode="pin" /> // to pin in place until it reaches the bottom of the layout
Implement AppBarLayout.OnOffsetChangedListener listener on your AppBarLayout to determine the CollpasingToolbar is collapsed or not and set Title in the Toolbar accordingly.
Call below method on OnCreate() of Activity.
private void setTitleOfLayout() {
AppBarLayout appBarLayout = findViewById(R.id.appbar_layout);
appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
boolean isShow;
int scrollRange = -1;
@Override
public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
if (scrollRange == -1) {
scrollRange = appBarLayout.getTotalScrollRange();
}
if (scrollRange + verticalOffset == 0) {
// orange part is not visible so set The title
if (myTitleName != null)
toolbar.setTitle(myTitleName);
isShow = true;
} else if (isShow) {
// orange part is visible so remove the title with
space here make sure your are not setting null in toolbar.
toolbar.setTitle(" ");
isShow = false;
}
}
});
}
