How to keep all items bound to the bottom of recycler view when item expands?

Is there any way to keep the other, non-expanded items located at the bottom. In the second picture, the items shift up to the top--this is not desired.
Here is the item that is shown in the pictures above.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Here is the parent layout where the recycler view is contained.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"
android:layout_width="match_parent"

android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_weight="1"
android:focusable="true"
android:orientation="horizontal"
tools:listitem="#layout/item" />
</LinearLayout>
Here is my onScroll listener that is responsible for making the massive text view visible or gone:
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
int centerPos = layoutManager.findFirstCompletelyVisibleItemPosition();
View centerView = lifeTimelineRV.getLayoutManager().findViewByPosition(centerPos);
if (prevCenterPos != centerPos) {
// dehighlight the previously highlighted view
View prevView = lifeTimelineRV.getLayoutManager().findViewByPosition(prevCenterPos);
if (prevView != null) {
View previousView = prevView.findViewById(R.id.item_life_event_id);
previousView.setSelected(false);
previousView.findViewById(R.id.massive_text_view).setVisibility(View.GONE);
Log.d(TAG, "onScrolled: not focused" + prevCenterPos);
// run scale animation and make it bigger
// Animation anim = AnimationUtils.loadAnimation(getContext(), R.anim.scale_out_item);
// previousView.startAnimation(anim);
// anim.setFillAfter(true);
}
// highlight view in the middle
if (centerView != null) {
View currentView = centerView.findViewById(R.id.item_life_event_id);
currentView.setSelected(true);
Log.d(TAG, "onScrolled: focused" + centerPos);
currentView.findViewById(R.id.massive_text_view).setVisibility(View.VISIBLE);
// run scale animation and make it smaller
// Animation anim = AnimationUtils.loadAnimation(getContext(), R.anim.scale_in_item);
// centerView.startAnimation(anim);
// anim.setFillAfter(true);
}
prevCenterPos = centerPos;
}
}
Here is my desired output. Is something like this possible? The first picture on the left is what I want. The second is what currently happens.

Tablayout vertical tab layout with badge

I've been having some problems with this particular layout for the better part of an hour, and I can't seem to get it to layout as expected. I've done the usual googling around this sort of format for the tab, and nothing seems to be exactly what I'm after.
I have a TabLayout where the tabs are laid out vertically, with an ImageView and a TextView using the default View of the tab.
It looks like this:
Ideally all I want to be able to do is to mimic this layout and anchor a TextView as a badge counter to the top right of the icon.
Like this:
So with that in mind I found a decent approximation of how the default tab layouts actually appear and it used the default ID's so I don't have to assign them programmatically which I thought was pretty nifty:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_marginBottom="4dp"
android:layout_marginTop="4dp">
<ImageView
android:id="#android:id/icon"
android:layout_gravity="center"
android:layout_width="24dp"
android:layout_height="24dp"
android:scaleType="centerInside" />
<TextView
android:id="#android:id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#drawable/tab_selector"
android:ellipsize="end"
android:textAllCaps="true"
android:gravity="center"
android:maxLines="2" />
</LinearLayout>
<TextView
android:id="#+id/badgeCounter"
android:layout_width="wrap_content"
android:layout_height="20dp"
android:minWidth="20dp"
android:textAlignment="center"
android:background="#drawable/count_background"
android:textSize="15sp" />
</RelativeLayout>
After a lot of tinkering and trying different things, I got to this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

<ImageView

android:src="#drawable/tab_home" />
</FrameLayout>

android:textColor="#color/FeatureFontColour"
android:textAlignment="center"
android:background="#drawable/count_background"
android:textSize="15sp"
android:layout_alignTop="#+id/iconFrame" />
</RelativeLayout>
No matter what I try, I can't get the badge TextView to appear in the right place, I've tried removing the linear layout so that I can set it to Layout_RightOf the #android:id/icon, I've tried wrapping the icon in a frame and setting Layout_RightOf that instead just incase the icon was not positioned before the badge TextView was created etc.
This is as close as I can get (Spoiler, not that close):
Any help would be appreciated, I'm not sure what exactly I'm missing, but odds are it's something really obvious.

Try this:
<?xml version="1.0" encoding="utf-8"?>

You can play with the margin right/top values to fine tune it.

The thing you missed here is as follows,
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/lnrButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_marginBottom="4dp"
android:layout_marginTop="4dp">
<ImageView
android:id="#android:id/icon"
android:layout_gravity="center"
android:layout_width="24dp"
android:layout_height="24dp"
android:scaleType="centerInside" />
<TextView
android:id="#android:id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#drawable/tab_selector"
android:ellipsize="end"
android:textAllCaps="true"
android:gravity="center"
android:maxLines="2" />
</LinearLayout>
<TextView
android:id="#+id/badgeCounter"
android:layout_width="wrap_content"
android:layout_height="20dp"
android:alignRight = "#+id/lnrButton"
android:alignTop = "#+id/lnrButton"
android:minWidth="20dp"
android:textAlignment="center"
android:background="#drawable/count_background"
android:textSize="15sp" />
</RelativeLayout>
Following is you missed
android:alignRight = "#+id/lnrButton"
android:alignTop = "#+id/lnrButton"
or if you want to come the badge on the image means, remove all LinearLayout and make it Relativelaout and instead of lnrButton use imageview id

I'm trying to expand the "product description" TextView when the CardView is clicked by passing it to the following method:
public static void expand(final View v) {
final int initialHeight = v.getHeight();
v.measure(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
final int targetHeight = v.getMeasuredHeight();
v.getLayoutParams().height = 1;
v.setVisibility(View.VISIBLE);
Animation a = new Animation() {
#Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
v.getLayoutParams().height = interpolatedTime == 1
? LinearLayout.LayoutParams.WRAP_CONTENT
: (int) (targetHeight * interpolatedTime);
v.requestLayout();
}
#Override
public boolean willChangeBounds() {
return true;
}
};
// 1dp/ms
a.setDuration((int) ((initialHeight / v.getContext().getResources().getDisplayMetrics().density))/10);
v.startAnimation(a);
}
The resulting animation is initially smooth but suddenly expands the view to full hight at the end
I got the code I'm using from this answer:

FlipWidthAnimation a = new FlipWidthAnimation(instructiuni);
a.setDuration(1000);
a.setParams(lp.width, getWindowManager().getDefaultDisplay().getWidth());
instructiuni.startAnimation(a);
}
he come in event is not a problem i debuged i see no error , but animation not started , but for example if click on settings animation started if was presset instructions before press settings. realy have no ideea why .

Solution was to give invalidate() my button: here is link who help me

Then make this call
ratingRl.animate().translationY(- ratingRl.getHeight());
But it doesn't slide into the screen. If the view is in the screen to start off with, the view does animate. What is the problem?

ratingRl.animate().translationY(- ratingRl.getHeight()).setDuration(300).start();

I have done similar task in my recent project.
background = (RelativeLayout) findViewById(R.id.slidingBackground);
positionOffScreen(background);
private void positionOffScreen(View v){
View myView = v;
int amountOffscreen = (int)(getScreenWidth());
boolean offscreen = true;
int xOffset = (offscreen) ? amountOffscreen : 0;
RelativeLayout.LayoutParams rlParams = (RelativeLayout.LayoutParams)myView.getLayoutParams();
rlParams.setMargins(-1*xOffset, 0, xOffset, 0);
myView.setLayoutParams(rlParams);
}
protected float getScreenWidth() {
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
return (float) displaymetrics.widthPixels;
}
When you want to start animation call this method
private void startAnimation(int duration){
TranslateAnimation a = new TranslateAnimation(Animation.ABSOLUTE,0,Animation.ABSOLUTE,getScreenWidth(),Animation.ABSOLUTE,0,Animation.ABSOLUTE,0);
a.setDuration(duration);
a.setFillAfter(false);
background.startAnimation(a);
}
When you want to interrupt animation
background.clearAnimation();
Here is layout example. The sliding view has to be placed on RelativeLayout.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/background" >
<RelativeLayout
android:id="#+id/slidingBackground"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#64000000"
android:orientation="vertical" >
</RelativeLayout>
...
And this is the app link where I use this sliding view.
