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.

I'm encountering some really strange behaviors with RecyclerView and it's about anchoring and aligning views inside one row of RecyclerView. So here is how the result from row should look:
And here are two pictures showing final result:
This is not happening always. Sometimes views inside are messed up like on attached images above and sometimes are not. Anyway here is my xml file showing how row layout looks:

I'm doing some hiding views inside adapter when i need to, and maybe that's an issue, i really don't know. I have tried without hiding views when checking some conditions inside adapter, but same results. Just to explain, i'm hiding inbox icon because if my username is showed in list i would like to hide it because i wouldn't want to send myself message and also this badge icon will be shown to one user only.
Here is code from adapter:
#Override
public void onBindViewHolder(final TeamMembersListAdapter.HeaderViewHolder holder, int position) {
final User user = teamUsers.get(position);
Glide.with(mContext)
.load(Uri.parse(user.getImage()))
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
.placeholder(R.drawable.ic_zelena_bez_lopte)
.error(R.drawable.ic_zelena_bez_lopte)
.dontAnimate()
.into(holder.profileImage);
String selfUserId = AppController.getInstance().getDatabase().getUserDetails().get("user_id");
if (user.getCreatorId() == Integer.parseInt(user.getId())) {
holder.ivBadge.setVisibility(View.VISIBLE);
} else {
holder.ivBadge.setVisibility(View.INVISIBLE);
}
if (selfUserId.equals(user.getId())) {
holder.ivSendMessage.setVisibility(View.INVISIBLE);
} else {
holder.ivSendMessage.setVisibility(View.VISIBLE);
}
holder.tvUsername.setText(user.getName());
holder.tvCityName.setText(user.getCity());
holder.bgContainer.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mOnItemClickListener.onItemClickListener(holder.getAdapterPosition());
}
});
}
Shouldn't all views be together inside the RelativeLayout?
I don't get why You even need the CoordinatorLayout, maybe try to get rid off Coordinator and wrap all inside Relative.
I would suggest also to try the ConstraintLayout - it should be super easy to done this in such layout.
Here, check this out

Here is what I am trying to do. I am creating a drag and drop controller. Users are able to move the controls where they want on the screen to save it. I have everything else done, except this. I have thought of a couple different ideas to get this to work, but most of them do not work so well with the drag and drop feature.
I have created an XML file.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:layout_width="50dp"
android:layout_height="40dp"
android:text=""
android:id="#+id/dpad_up"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:visibility="invisible"/>
<Button
android:layout_width="50dp"
android:layout_height="40dp"
android:text=""
android:id="#+id/dpad_down"
android:layout_below="#+id/dpad_up"
android:layout_centerHorizontal="true"
android:visibility="invisible"/>
<Button

android:visibility="invisible"/>
<Button
android:layout_width="50dp"
android:layout_height="40dp"
android:text=""
android:id="#+id/dpad_right"
android:layout_alignParentTop="true"
android:layout_toEndOf="#+id/dpad_up"
android:layout_marginTop="22dp"
android:visibility="invisible"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/d_pad"
android:background="#drawable/d_pad"
android:layout_alignParentTop="true"
android:layout_alignBottom="#+id/dpad_down"
android:layout_alignStart="#+id/dpad_left"
android:layout_alignEnd="#+id/dpad_right" />
</RelativeLayout>
I was thinking of using that XML bring into my activity and do a drag and drop, but I am not sure how I could do that. Any ideas or help would be great. I just need to be able to perform a drag and drop and have each of the directions buttons register when pressed to perform the action.
Invisible views are not touchable.
Just change Button into View or Space, and let it visible.
Currently I'm creating an app and ran into a weird issue. My activity has this layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_marginEnd="8dp"
android:layout_marginTop="105dp"
android:gravity="center"
android:maxLines="1"
android:maxWidth="216dp"
android:textColor="#color/grey" />
<TextView
android:id="#+id/id_unit"
style="#style/font_Title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/id_result"
android:layout_alignBottom="#+id/id_result"
android:layout_alignStart="#+id/id_image"
android:maxLines="1"
android:maxWidth="80dp"
android:textColor="#color/grey" />
<ImageView
android:id="#+id/id_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/id_unit"
android:layout_marginBottom="27dp"
android:layout_toEndOf="#+id/id_result" />
<ImageView
android:id="#+id/id_image2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignStart="#+id/id_image"
android:layout_alignTop="#+id/id_result" />
</RelativeLayout>
</RelativeLayout>
In my onCreate() I call the Views by their ID and set the texts and the drawables. Depending on a meassured result, there are two scenarios:
1) Show the meassured result (let's say 42.9 GW/ms)
TextView id_result: '42.9'
TextView id_unit: 'GW/ms'
ImageView id_image: #drawable/image1_1
ImageView id_image2: #drawable/image2_1
Everything is fine
2) The result is too high
TextView id_result: 'HI'
TextView id_unit: visibility GONE
ImageView id_image: visibility GONE
ImageView id_image2: visibility GONE
Now here is the problem. I expected the text 'HI' to be shown centered on screen. Instead, only "H" is shown. When I set android:maxLines="2", it is revealed, that Android wraps the text after 'H'. 'I' sits on the second line. Why is this the case? '42.9' is longer and doesn't get wrapped.
Does anyone has a solution?
I am trying to show a pair of hidden buttons (using setVisibility(View.VISIBLE), within a RelativeLayout), but it doesn't always work. The button shows OK on a Galaxy Tab 10.1" but not in a smaller tablet (not sure which model), nor on an Android 4.0 emulator.
I randomly discovered that, for a certain TextView t, the following code causes the buttons to become visible:
t.setText(t.getText());
...
button.setVisibility(View.VISIBLE);
t is located in the same RelativeLayout but is not related to the buttons (their locations are independent and non-overlapping).
Edit: In case some Android dev wants to track this down...
I was able to reduce the code to the following layout that exhibits the problem on an Android 4.0.3 emulator but not a Galaxy Tab. I found that I need a SurfaceView or the problem does not occur (for example, change it to TextView and the problem disappears).

The Activity class simply toggles the visibility of the two buttons when any of the buttons are clicked. Again, on some devices it works, on others it does not.

SurfaceView is the sole culprit (of course, this also applies to GLSurfaceView, RSSurfaceView and VideoView, all of which inherits from SurfaceView). It exposes lots of weird behaviours when dealing with other views on top of it. Playing with View.setVisibility() is one of those issues. Clearly, SurfaceView has not been designed to be used with other views (even though the official doc says it ought to be) but as a standalone view for videos, games or OpenGL stuffs.
For the visibility issue, I've found that using View.GONE instead of View.INVISIBLE resolve it. If you don't want to use GONE, try changing the focus for example (and back to the one that had focus before), or changing other states. The goal is to wake up the underlying UI system somehow.
In short: when something weird happens with your views and you have a SurfaceView (or subclass) somewhere, try replacing it with something else so you don't lose hours searching what you're doing wrong when you're doing it right (and no false beliefs). This way, you know SurfaceView is to blame and you can hack around it with beautiful comments to piss on it without qualms.
For the record: I had this problem, tried a bunch of random stuff (thanks Alex!), and in my case what solved it was doing seekBar.requestLayout() directly after the setVisible on the very seekbar that was refusing to show.
This is my Solution
setAlpha(0)
btnName.setAlpha(0)
Is working for all views like => Buttons - Images - Texts and ...
In my case View.VISIBLE/View.GONE was not working always. When I switched my toggle to View.VISIBLE/View.INVISIBLE it started to work as intended.
I (annoyingly) had similar difficulty with having a button on top of a SurfaceView preview and had to put the Button in a RelativeLayout and make the RelativeLayout VISIBLE/INVISIBLE. Might be worth a shot for anyone else having the same issue.
...And I also had to programatically call the layout to be brought to from: buttonLayout.bringToFront() right after findViewById.
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.
