Programmatically move a view Android

I have an imageView that I want to move given a specific situation.
Initially I have a Relative layout with two textViews and an imageview. The textViews are oriented with one above the other. The imageView is set
android:layout_below="#id/text_view1"
android:layout_toEndOf="#+id/text_view2".
In the logic text_view2 is removed when a specific condition is met. I want to programmatically move the imageView to the end of text_view1 when this condition is met. Essentially when text_view2 is removed, I want to set the imageView to
android:layout_toEndOf="#+id/text_view1"
I don't believe setting X,Y,Z values is appropriate here because programmatically, I don't know where the imageView will show up given different screen sizes, and densities. I just need it to move to the end of the first textView.

Take a look at RelativeLayout.LayoutParams. You will need to manipulate the layout rules in the layout params as follows:
// Make textView2 invisible
tv2.visibility = View.INVISIBLE
// Get the LayoutParams of the ImageView
val ivParams = iv.layoutParams as RelativeLayout.LayoutParams
// Change the rule to be to the right of textView1
ivParams.addRule(RelativeLayout.RIGHT_OF, tv1.id)
// Since the placement of textView2 is changing, request a layout.
iv.requestLayout()
Consider using "END_OF" instead of "RIGHT_OF".

You can either place the Views in a nested LinearLayout or use a ConstraintLayout with a Barrier.
It is generally recommended to use ConstraintLayout because nested LinearLayouts are bad for performance but since ConstraintLayout takes some getting used to, I did not want to omit the other option.
To demonstrate the two approaches I've set up a small example with a LinearLayout and a ConstraintLayout in the same screen:

If the ImageView is clicked, the longer TextView will disappear and the ImageView will move closer to the short TextView. The animations are provided by Android's transition framework, so basically all you have to do is trigger the transition by calling TransitionManager.beginDelayedTransition()
For demonstration purposes, I've placed all the code in one method. Please note that normally one would have the TransitionSet as field of the Fragment so that it does not have to be recreated every time you need it. (The code is in Java since Android Studio supports automatic translation to Kotlin if required but not the other way round ;-) )
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
TransitionSet ts = new TransitionSet();
ts.addTransition( new ChangeBounds());
ts.addTransition(new Slide());
View imageViewInLinearLayout = view.findViewById(R.id.linearLayoutImageView);
imageViewInLinearLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
TransitionManager.beginDelayedTransition((ViewGroup)getView(), ts);
view.findViewById(R.id.longTextViewInLinearLayout).setVisibility(GONE);
}
});
View imageViewInConstraintLayout = view.findViewById(R.id.constraintLayoutImageView);
imageViewInConstraintLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
TransitionManager.beginDelayedTransition((ViewGroup)getView(), ts);
view.findViewById(R.id.longTextViewInConstraintLayout).setVisibility(GONE);
}
});
}

Horizontal android:animateLayoutChanges="true" Animation not smooth

I have a layout that animate as below
The txt_billion is shown dynamically, with android:animateLayoutChanges="true" (Layout code below).
Notice the Hundred is jumping (actually all are jumping, but the Hundred is just more obvious). How to prevent the text from jumping?
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:animateLayoutChanges="true"
android:orientation="horizontal">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:padding="8dp"
android:background="#9f9"
android:text="Hundreds" />
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:padding="8dp"
android:background="#f9f"
android:text="Thousands" />
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:padding="8dp"
android:background="#0ff"
android:text="Millions" />
<TextView
android:id="#+id/txt_billion"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:padding="8dp"
android:visibility="gone"
android:background="#ff0"
android:text="Billions" />
</LinearLayout>
You could get the code from https://github.com/elye/issue_horizontal_layout_animate to test out

Try to use Support Transitions instead animateLayoutChanges
First, remove android:animateLayoutChanges="true" from your XML file
After, add compile 'com.android.support:transition:25.4.0' to your app dependencies.
Then, add this line before change visibility (TransitionManager from android.support.transition package)
TransitionManager.beginDelayedTransition(parentOfAnimatedView);
For your code
public void clickMe(View view) {
TransitionManager.beginDelayedTransition((ViewGroup) billionText.getParent());
if (billionText.getVisibility() == View.GONE) {
billionText.setVisibility(View.VISIBLE);
} else {
billionText.setVisibility(View.GONE);
}
}

The problem is that animateLayoutChanges only affects subclasses of ViewGroup. TextView can't react to layout change animations, so the text jumps. There are two ways to fix it:
1) Wrap each TextView in a FrameLayout and put the weight on the FrameLayout. You'll also have to add android:animateLayoutChanges="true" to each, as well as calling getLayoutTransition().enableTransitionType(LayoutTransition.CHANGING) on each FrameLayout. This is kind of gross layout-wise, but it will allow you to keep using the transition animations.
2) Use a ValueAnimator and animate the weight of the (dis)appearing item. The animation may be a little choppier since it needs to lay out the LinearLayout on each frame, but it should still be passable. You'd also have to solve for text reflowing on the disappearing item, maybe by animating it fading out first and then animating the weight change.

Multiple Empty View for one ListView

I have a ListView, with an Empty View that shows a progressbar to indicate that the app is still loading. I want to make a second empty view to tell the user if there is some error during the process.
I have tried with 2 relative layouts, but when I need to set the "error view", it just ignore it and shows only the "loading view".
So I have tried with a single layout, with my progressbar and the others things to make the error screen, with VISIBILITY:GONE. But, when it's time to put VISIBILITY to VISIBLE, I receive a NullPointerException.
I don't really know what I'm supposed to do to make it works... Thank you!
EDIT
this is my Layout right now (the VISIBILITY attempt) UNDER the ListView
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent" android:id="#+id/post_list_loading">
<ProgressBar
style="?android:attr/progressBarStyle"
android:layout_width="125dp"
android:layout_height="125dp"
android:layout_centerInParent="true"
android:id="#+id/post_list_loading_progressbar"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:visibility="visible" />
<ImageView
android:layout_width="125dp"
android:layout_height="125dp"
android:layout_centerInParent="true"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:src="#drawable/post_list_error_image"
android:visibility="gone"
android:id="#+id/post_list_error_image"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/post_list_error_image"
android:text="Error Text"
android:maxLines="2"
android:ellipsize="end"
android:layout_marginLeft="50dp"
android:layout_centerHorizontal="true"
android:textSize="21dp"
android:id="#+id/post_list_error_text"
android:layout_marginTop="5dp"
android:visibility="gone"
/>
<Button
android:id="#+id/post_list_error_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/post_list_error_text"
android:text="Ricarica"
android:layout_centerHorizontal="true"
android:layout_marginLeft="50dp"
app:backgroundTint="#color/colorPrimary"
android:textColor="#color/colorWhite"
android:visibility="gone"
/>
</RelativeLayout>
The first method I have tried was about putting everything after the progressbar in another RelativeLayout.
So my idea was to make a function to switch between the two views, playing with the Visibility settings.
public void emptyViewManager(Boolean isError, String errorMessage)
{
// [...]
if (isError == true)
{
// Error View
emptyView_progress.setVisibility(View.GONE);
emptyView_errorImage.setVisibility(View.VISIBLE);
emptyView_errorText.setVisibility(View.VISIBLE);
emptyView_errorButton.setVisibility(View.VISIBLE);
emptyView_errorText.setText(errorMessage);
}
else
{
// Loading View
emptyView_progress.setVisibility(View.VISIBLE);
emptyView_errorImage.setVisibility(View.GONE);
emptyView_errorText.setVisibility(View.GONE);
emptyView_errorButton.setVisibility(View.GONE);
}
}
But this didn't work because I have a NullPointerException when the App reach the setVisibility function.

Button Inside Android ListView doesnt respond to clicks

I have a default ListView that i have added my custom views for the list items, but the buttons inside of these views are not clickable most of the time. I output a Log.v when the button receives a click event, but i have to tap the button almost a dozen times before it will register the click.
The other problem related tot his that i am having is that when the button is pressed i want an animation to happen revealing a menu sliding out from beneath it. At the moment i have tried several different methods like making a custom class for the views versus just using a layout inflater to get the relativeLayout object for the view, but nothing is working properly. I have even tried using listview.getAdapter().notifyDataSetChanged(); but that only has a pop-into-place for the extended view when i want an animation.
I have searched everywhere and it seems like the only possible solutions are to either rewrite my own custom listview or to use a linearlayout with a scrollview. The latter seems easier but i dont think it is nearly as optimized as the listview is.
Any suggestions would be greatly appreciated, if you need to see some code, please let me know...
Thanks!
UPDATE:
the getView() contains this:
Holder hold;
convertView = friends.get(position);
hold = new Holder();
hold.pos = position;
convertView.setTag(hold);
return convertView;
basically i pass an ArrayList<RelativeLayout>, at the moment, to the Adapter so that i dont have to create a new view each time and so that the animation will stay animated when i scroll down...
inside the OnCreate() for this activity i set that ArrayList<RelativeLayout> with this next code, but this is only temporary as i plan to use another method later, like an Async task or something so that this view contains some data...
RelativeLayout temp;
for(int i=0; i<30; i++){
temp = (RelativeLayout) inflater.inflate(R.layout.list_item, null);
final LinearLayout extraListItemInfo = (LinearLayout) temp.findViewById(R.id.extraListItemInfo);
Button infoBtn = (Button) temp.findViewById(R.id.infoBtn);
infoBtn.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
Log.v("ListItem", "Button has been clicked... ");
extraListItemInfo .setVisibility(View.VISIBLE);
ExpandAnimation closeAnim = new ExpandAnimation(extraListItemInfo , animHeight);
closeAnim.setDuration(750);
closeAnim.setFillAfter(true);
if(extraListItemInfo .getTag() == null || !extraListItemInfo .getTag().equals("expanded")){
extraListItemInfo .getLayoutParams().height = 0;
friendInfoList.startAnimation(closeAnim.expand());
extraListItemInfo .setTag("expanded");
}else if(extraListItemInfo .getTag().equals("expanded")){
extraListItemInfo .startAnimation(closeAnim.collapse());
extraListItemInfo .setTag("closed");
}
//((BaseAdapter) listview.getAdapter()).notifyDataSetChanged(); i tried it here once but then left it
//as the only action inside the listview's onitemclick()
}
});
listItems.add(temp);
}
this is the list item that i am using:

sorry for any layout problems that may make things difficult to read... but i hope this helps you guys to understand my problem... Thanks
UPDATE 2:
All of these answers have been helpful in some way, but i think the main issue that i must first fix is why the buttons do not receive click events until i have first scrolled away from that listItem, then back to it, then clicked the button again... If someone can help find a solution to THAT i think that everything else will be much easier to solve...
Thanks...
A screenshot as requested, but remember that this shot was taken on a samsung galaxy tab 10.1 and due to me using the same layout for this larger screen, it looks much different from what it does on the phone i usually test with (Motorola droid x that isnt rooted and cant take screenshots...)
Another Update:
I managed to get the clicking and animation working nicely by Extending ArrayAdapter instead of base adapter. Sadly i am still experiencing problems as only the bottom half of the list is clickable. The top half of the list still behaves as before with the very glitchy click events... Any ideas as to what is happening this time? Thanks...

Well this isn't really an answer, but after rewriting this a few times I managed to fix it so that it functions exactly the way I wanted.
This time I left all of the data separate from each view and had each list item be a custom class inheriting RelativeLayout and also implementing its own OnClickListener for its specific infoBtn.
My adapter now simply extends ArrayAdapter<> and overrides this getView() method:
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView != null && (convertView instanceof FriendListItem2))
((FriendListItem2) convertView).setFriendInfo(friends.get(position));
else
convertView = new FriendListItem2(getContext(), friends.get(position));
return convertView;
}
Finally, in the main activity for this page I simply set the ListView with an adapter that I passed the data to.
This is all much cleaner than I had before and I wish it hadn't taken several rewrites of the code to get it right. Hopefully someone can benefit from this, though I still have no clue why I was getting a problem before.
Thanks for all previous suggestions.

try using this property in the top level layout in which your child views are placed.
android:descendantFocusability="blocksDescendants"
Its a bit tricky but I would suggest that if the above line does not work, try toggling between the removing of focusable=true and focusable="false" from the buttons. It should work.
Cheers!

That is a complex layout to create for every row...
Anyway, when you use the new keyword you are creating a different scope. In short your onClickListener does not see the 30 different extraListItemInfo references you expect it to see.
Try something like this:
#Override
public void onClick(View v) {
LinearLayout extraListItemInfo = v.getParent();
...

add android:onClick="onClick" to your button xml, it'll make it call the onClick() method

I had the same problem. Try taking the "android:clicable="true" " from the Relative Layout. When you do that the activity expects you to do make setOnClickListener to that RelativeLayout . It worked for me

you can fire click event on button from getView() method of ListViewAdapter Class.

android setVisibility does not display if initially set to invisble

I have a glsurface occupying the full screen. At the click of a button I want another layout to appear (settings type of thing).

Had similar error but it was due to my silly mistake of not using the UiThread.
Activity act = (Activity)context;
act.runOnUiThread(new Runnable(){
#Override
public void run() {
mLayoutLights.setVisibility(View.VISIBLE);
} });

Got it. You have to set the visibility of all the items in the layout, not just the layout. So this code worked:
if (mLayoutLights.getVisibility() == View.VISIBLE) {
((Button) findViewById(R.id.btnLightsOK)).setVisibility(View.GONE);
((Button) findViewById(R.id.btnLightsCnc)).setVisibility(View.GONE);
mLayoutLights.setVisibility(View.GONE);
} else {
mLayoutLights.setVisibility(View.VISIBLE);
((Button) findViewById(R.id.btnLightsOK)).setVisibility(View.VISIBLE);
((Button) findViewById(R.id.btnLightsCnc)).setVisibility(View.VISIBLE);
}

In my case, with a plain SurfaceView, I just set the View to GONE in xml, not INVISIBLE. Then I can set VISIBILITY correctly after that.

I have faced the same problem and debug log was clearly showing that the visibility is correctly set.
I was using databinding. For me the solution below worked.
activity.runOnUiThread(() -> binding.getRoot().post(() -> {
binding.additionalDataHolderOne.setVisibility(View.GONE);
binding.firstStreamHolder.setVisibility(View.VISIBLE);
}));
Actually, binding.getRoot().post(() -> {}); did the job.

I would suggest trying three independent things.
Changing layout width and height to wrap content as it could be an issue with matching the parent.
Calling bringToFront on the view
Wrapping the surfaceView in a FrameLayout (this is related to #2, but it still might help)

if you set the CalendarView to visibility "VISIBLE" and in the inflateView/OnCreateView after you find it with "findById" just set to "GONE" and you can do what ever you want with it.
calendarView = (CalendarView)
view.findViewById(R.id.all_scores_calendar_view);
calendarView.setVisibility(View.GONE);
calendarView.setVisibility(View.VISIBLE);

I don't why is not working (for me also) but as a workaround you can do:
val params = mLayoutLights.layoutParams
if (shoouldShow()) {
params.height = WRAP_CONTENT
} else {
params.height = 0
}
mLayoutLights.layoutParams = params

I faced a problem like this before I was put 2 views in a LinearLayout.
one of the 2 views is gone and the other one is visible.
and when I try to make the gone one visible and the visible one gone,
it was not working.
I solved this issue by using RelativeLayout as a container layout instead of the LinearLayout, It's working fine then.

In my case, I have called .setVisiblity(View.GONE) in an element where visibility is GONE
if (temp.getVisibility() == View.VISIBLE) {
temp.setVisibility(View.GONE);
}
doing something like that worked for me.

In my case I just changed layout id and it worked.

If you are using ViewBinding and you have a nested View via Include with a View whose Id is the same as in the main View, there may be a situation that the Visiblity property is not applied to one of these Views

i don't know whats reas of not working but i put my layout into cardview and set cardview visiblity gone and it's work for me
