Aligning Selected Spinner Item

I'm trying to make a slight adjustment to the positioning of the selected item in the spinner. Not the dropdown list items, as I already have a custom view in my adapter for that, but the selected item specifically.
As you can see in the screenshot, "Any" is the currently selected item. But it is aligned oddly within the container because it has to accommodate the longest string in the dropdown, which is "Dark Purple Burnt Sienna" (or whatever). I want to align the selected text to the right so that "Any" is next to the dropdown indicator instead of way out in the middle.
I've attempted to make adjustments to my custom spinner-item view, but it doesn't have any affect on the selected item.
I've also attempted to set gravity and text alignment on the Spinner itself, but it has no effect.
Here's the image and the xml:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#color/default_black"
android:layout_centerVertical="true"
android:text="Color" />
<Spinner
android:id="#+id/spn_color"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
</RelativeLayout>
Edit: Here's my adapter:
public class ColorsAdapter<T> implements SpinnerAdapter {
ArrayList<String> mColors;
ArrayList<Integer> mValues;
Context mContext;
public ColorsAdapter(ArrayList<String> colors, ArrayList<Integer> values,
Context context) {
mContext = context;
mColors = colors;
mValues = values;
}
#Override
public int getCount() {
return mColors.size();
}
#Override
public Object getItem(int position) {
return mColors.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public int getItemViewType(int position) {
return R.layout.list_item_color;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView v = new TextView(mContext);
v.setText(mColors.get(position));
return v;
}
#Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(
Context.LAYOUT_INFLATER_SERVICE );
View row = inflater.inflate(getItemViewType(position), parent, false);
TextView tvName = (TextView)row.findViewById(R.id.tv_name);
tvName.setText(mColors.get(position));
row.setTag(mValues.get(position));
return row;
}
#Override
public int getViewTypeCount() {
return 1;
}
#Override
public boolean hasStableIds() {
return false;
}
#Override
public boolean isEmpty() {
return false;
}
}
And here's the XML for the list item:
<TextView
android:id="#+id/tv_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:gravity="right"/>

You can adjust the settings for selected item in getView(int position, View convertView, ViewGroup parent) method. If you just want to set the gravity and text alignment, you should set it to the TextView in the method like
#Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView v = new TextView(mContext);
v.setText(mColors.get(position));
v.setGravity(Gravity.END); // OR v.setGravity(Gravity.RIGHT);
return v;
}
Or you can simply inflate custom layout if you want to make further customization:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(
Context.LAYOUT_INFLATER_SERVICE);
View row = null;
if (inflater != null) {
row = inflater.inflate(R.layout.list_item_view_color, parent, false);
TextView textView = row.findViewById(R.id.textview);
textView .setText(mColors.get(position));
}
return row;
}
Where list_item_view_color.xml is your layout file for the selected value.
(NOTE: If you want to use options like autoSizeTextType, you can use them with app prefix for AppCompatTextView in xml files)

Simple solution would be to build another Custom view for the spinner TextView layout, and specify the gravity for your TextView in that. Something like :
<!--spinner_layout.xml (in layout/)-->
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="right"
/>
Use that in initalising the ArrayAdapter of your spinner :
ArrayAdapter<String> adapter = new ArrayAdapter<String>
(this, android.R.layout.spinner_layout,
spinnerArray);
UI output :

You can creating the TextView for the getView method programmatically so no property for alignment is being set, easy thing to do is inflate it in the same way you are doing it on the getDropdownView, or simply set the proper gravity in the view you are instantiated.
#Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView v = new TextView(mContext);
v.setText(mColors.get(position));
v.setGravity(Gravity.RIGHT);
return v;
}

You can try this
android:autoSizeTextType="uniform"

Padding, Margins and Alignments get confusing when it comes to Spinners. I ran into a similar issue as well. But for me I wasn't using a custom view and adapter, so I managed to use styles to get around this issue.
For you since you are already using custom view and adapter, you can make the background null for the spinner so that the dropdown arrow will not be visible.
android:background="#null"
Then in the TextView, you can assign drawableRight to be the dropdown arrow.
android:drawableRight="#drawable/ic_spinner_drop_arrow_white_24dp"
The icon can be a dropdown vector drawable. Also to specify particular margin between the arrow and text, you should be able to use drawablePadding
Hope this helps.

I can give you a method that may work.
In XML
1) add a new text view called the_current_color text view
2) allign this text view above the spinner and to the start of the arrow icon
or wherever you want it to be.
In your code
1) when you listen to (on item selected ) from the spinner simply get the current text and set it in the (the_current_color) text view.
2) and try to hide the texts in the spinner by changing color to transparent.
Hope it works
Edit
I might also suggest something maybe it changes things
lets say that we have a spinner that uses this string resource file to populate its adapter
<string-array name="my_adapter">
<item>Blue </item>
<item>Red</item>
</string-array>
until now we have a spinner that shows (red item) and (blue item) at the far left from the arrow icon of the spinner.
create another string resources now like that
<string-array name="my_adapter_two">
<item> Blue </item>
<item> Red</item>
</string-array>
as you can see now the added space will give an illusion that the strings are beside the arrow icon
you can add space that fit your need and you can maybe switch the files after you click a certain item and then switch them back.

You can try the following Custom view.
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/textView1"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:gravity="right"
android:padding="15dp"
android:textAlignment="gravity"
android:textColor="#color/black"
android:textSize="10dp" />

Changing background color of ListView item upon clicking a Button

Apologies if this question has been asked previously.
I have a ListFragment that contains a Button in each list item. Clicking on the Button should change the background color of that particular list item. I understand that the ListView inside the ListFragment refreshes itself implying that if a user scrolls it is likely that a list item that was not previously clicked will have its background color changed.
Many of the solutions I have come across involve storing the position of the list item that was clicked in an overridden getView(int position, View convertView, ViewGroup parent) method implemented in a custom adapter (that extends SimpleAdapter in my case).
However my problem is compounded by the presence of a Button inside every list item implying that the Button will not be clickable unless I attach an OnClickListener inside a custom adapter (this part is done). Now, trying to store the position of the Button's list item fails because the saved position is always a refreshed position and not the absolute position of the list item. I also tried setting tags for each button but even those get recycled as the page scrolls, which is (unfortunately) expected behaviour considering the design of ListView.
I understand that this problem is easily solvable if the a list item does not have children that need to be clicked. But what if there are children within every list item that need to respond to clicks separate from the parent view that contains each list item ? I have also tried using selectors to manipulate a list item's background but that hasn't helped either.
Here is my Custom Adapter's getView method:
#Override
public View getView(int position, View convertView, ViewGroup parent){
View view = convertView;
final int pos = position;
if(view == null){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.fragment_layout, null);
Button button = (Button) view.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Log.d("CLICKED POSITION",Integer.valueOf(pos).toString());
View parent = (View) v.getParent();
parent.setBackgroundColor(Color.GREEN);
}
});
}
return view;
}
And the XML layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="300dp"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_weight="1"
android:descendantFocusability="blocksDescendants"
android:layout_margin="5dp"
>
<ListView android:id="#id/android:list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/label"
android:layout_gravity="start"
/>
<TextView
android:id="#+id/text_id"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_gravity="end"
/>
<Button
android:id="#+id/button"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="#string/button"
android:layout_margin="2dp"
android:layout_marginLeft="2dp"
android:layout_marginRight="2dp"
android:clickable="true"
/>
</LinearLayout>
I have spent many hours on this problem and I am unable to arrive at a solution. Any direction, guidance or a solution would be most appreciated.

In your Custom Adapter's getView() method, you are inflating the view and attaching the onclicklistener only if the convertView is null. convertView IS the recycled view. If convertView is not null, then you need to change the values in that view. Your getView() method should be like this instead
#Override
public View getView(int position, View convertView, ViewGroup parent){
View view = convertView;
final int pos = position;
//No recycled view, so create a new one
if(view == null){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.fragment_layout, null);
}
//By this line, we either have a view that is created in the if block above or passed via convertView
Button button = (Button) view.findViewById(R.id.button);
//attach listener to the view, recycled or not
button.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Log.d("CLICKED POSITION",Integer.valueOf(pos).toString());
//parent not required as we are have the view directly
//View parent = (View) v.getParent();
v.setBackgroundColor(Color.GREEN);
}
});
return view;
}
Indeed you should also be changing any values associated with that item according to that position, if they change. For example, if each button displays the position in the list, you should also add the following line
button.setText("Button " + position);

not passing right Parameters in adapter

I'm trying to create a horizontal scroll view inside a listView. My main activity uses xml containing listview. It calls a custom adapter which extends a base adapter. This custom adapter inflates a xml containing HorizontalListview and getView method calls another adapter.
THis is my custom Adapter that inflates a xml containing a TextView and a HorizontalListView. I call an adapter for the HorizontalListView inside the getView, in which i pass in my activity, and I also pass in the array of items. When I run my application the customAdapter works fine and I get the right views, but my HorizontalListView doesn't show up at all. I don't think I'm passing in the right parameters. I thought passing the activity would be good, but I guess not.
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
LinearLayout lg = (LinearLayout) convertView;
if(lg == null) {
lg = (LinearLayout)firstInflator.inflate(R.layout.second_layout,null);
holder = new ViewHolder();
holder.hlv1 = (HorizontalListView)lg.findViewById(R.id.listview);
lg.setTag(holder);
}
else {
holder = (ViewHolder)lg.getTag();
}
mVideos = dA.mShows.get(categories[position]);
holder.hlv1.setAdapter(new HorizontalGalleryAdapter(dA, mVideos));
((TextView) lg.getChildAt(0)).setText(categories[position]);
return lg;
}
THis is my HorizontalGalleryAdapter. My problem is that only the first adapter is working properly.
private final LayoutInflater mInflator;
private ArrayList<Video> mVideos;
private final ImageDownloader mDownload = new ImageDownloader();
public HorizontalGalleryAdapter(DataActivity da, ArrayList<Video>mVideos){
mInflator = da.getLayoutInflater();
this.mVideos = mVideos;
}
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
LinearLayout lg = (LinearLayout)convertView;
if(lg == null) {
lg = (LinearLayout)mInflator.inflate(R.layout.third_layout,null);
}
imageView = (ImageView) lg.getChildAt(0);
mDownload.download(mVideos.get(position).mThumb.toString(), imageView);
((TextView) lg.getChildAt(1)).setText(mVideos.get(position).mTitle);
return lg;
}
This is my xml for the HorizontalListView
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#000000"
android:id="#+id/second">
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="bold"/>
<com.devsmart.android.ui.HorizontalListView
android:id="#+id/listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#808080">
</com.devsmart.android.ui.HorizontalListView>
</LinearLayout>

Using customlistviews in android : Keep on getting list view = NULL

I am new to android and am trying to create two fragments and have it so you can slide between the two, one is a list and the otehr a grid. I had the list working when it when I was using an ArrayAdapter and had my EventListFragment extending ListFragment (if code is helpful let me know and ill post that part)
I am now trying to create a custom list view with multiline list items (let me know if there is an easier way and if i have simply overcomplicated the whole thing)
Here is my code:
Event List Fragment:
public class EventListFragment extends Fragment {
ArrayList<EventObject> eventObjects;
#Override
public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
eventObjects = ((EventsActivity)getActivity()).getEventObjects();
View view = inflater.inflate(R.layout.eventgrid ,container,false);
Listview listView = (ListView) view.findViewById(R.id.listView);
if (listView == null) {
System.out.println("asas");
}
listView.setAdapter(new MyCustomBaseAdapter(getActivity().getBaseContext(), eventObjects));
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
Object o = listView.getItemAtPosition(position);
EventObject fullObject = (EventObject)o;
System.out.println("asd");
}
});
return view;
}
}
The corresponding xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<ListView
android:id="#+id/listView"
android:layout_height="wrap_content"
android:layout_width="fill_parent"/>
</RelativeLayout>
The xml for the customgridrow:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:id="#+id/name"
android:textSize="14sp"
android:textStyle="bold"
android:textColor="#FFFF00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView android:id="#+id/cityState"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView android:id="#+id/phone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
EDIT
The getView() from MyCustomBaseAdapter :
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.customgridrow, null);
holder = new ViewHolder();
holder.txtName = (TextView) convertView.findViewById(R.id.name);
holder.txtCityState = (TextView) convertView.findViewById(R.id.cityState);
holder.txtPhone = (TextView) convertView.findViewById(R.id.phone);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.txtName.setText(events.get(position).getName());
holder.txtCityState.setText(events.get(position).getDate());
holder.txtPhone.setText(events.get(position).getVenue());
return convertView;
}

From your comments
You are inflating the wrong layout
You should inflate the one that has listview and initialize the same.
Change
View view = inflater.inflate(R.layout.eventgrid ,container,false);
to
View view = inflater.inflate(R.layout.eventList ,container,false);

Every time you want to add an object to a list, you have to provide a view for the object. Android asks your list adapter, be it custom or system-defined, it asks the adapter what each list item is supposed to look like. This is where getView() comes into play.
public abstract View getView (int position, View convertView, ViewGroup parent):
Get a View that displays the data at the specified position in the data set.
If convertView is null, you will get an NPE.

Android Custom Adapter: list items only populated when scrolling

I'm having an issue getting my list populated correctly by my custom ArrayAdapter (code below). As I understand it, my adapter is only populating the textviewResourceId when it is instanciated since I'm using constructor Adapter(context, rowLayout, textViewResourceId, ArrayList<Items>), but the getView method is only called when rows that were not visible become visible.
This is causing an issue as, when my list is first showing, only the title of my article is showing, and I have to scroll all the way down the list and up for all the views in each row to be populated correctly (since that task is done in getView).
Can anyone point me in the right direction? How could I refactor this so all views in each visible row gets populated right away?
Code to my custom adapter:
import java.util.ArrayList;
import android.app.Activity;
import android.content.Context;
import android.graphics.drawable.Drawable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

this.articles = articles;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {

The problem is that you are not populating new views. What happens is that Android may keep a fixed number of views which will be used for your list view. The views are recycled which is why it's impossible to "populate" all your views before they become visible. This line
if (view == null) {
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
row = inflater.inflate(R.layout.affichageitem, null);
}
checks whether a view is being recycled or not. null means it's not, so if you get null you need to inflate a new view. Upto there your code's fine. However, you need to populate the view whether it's a newly inflated view or not. So you shouldn't have the else statement, just have
View row = convertView;
if (row == null) {
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
row = inflater.inflate(R.layout.affichageitem, null);
}
TextView viewTitre = (TextView)row.findViewById(R.id.titre);
TextView viewAuteur = (TextView)row.findViewById(R.id.auteur);
TextView viewDate = (TextView)row.findViewById(R.id.date);
ImageView viewLogo = (ImageView)row.findViewById(R.id.category_logo);
viewTitre.setText(getItem(position).getTitle());
viewAuteur.setText(getItem(position).getCreator());
viewDate.setText(getItem(position).getDate());
Drawable drawLogo = context.getResources().getDrawable(R.drawable.logocat);
viewLogo.setImageDrawable(drawLogo);
return row;
The reason why it worked when you scrolled all the way down is that on your way back up getView was receiving recycled views and it jumped right into the else clause you had.

You are using your own collection ArrayList<Article>.
Note that every ArrayAdaper<foo> already has data collection built in, where you can add by add(foo) or addAll(List<foo>) and clear it by clear() method.
Also, ListView can observe this data and refresh when changes happen to this data. Or explicitly when notifyDataSetChanged() is called on adapter.
Problem here is that you are accepting data in constructor, storing in yet another local variable, and notifyDataSetChanged() is not being called. You cannot call it from constructor as Object is still under construction.
So, Don't accept data in constructor. Inside getView() use getItem(position) to get Article item.
Add data externally like:
ArticleArrayAdapter adapter = new ArticleArrayAdapter(context,rowLayout,android.R.layout.simple_list_item_1);
adapter.addAll(articles);
myListView.setAdapter(adapter);

Looks correct to me - only thing: there is no need to call the superclass. Try to return your assembled view like that:
return row;

#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
if (row==null){
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
row = inflater.inflate(R.layout.affichageitem, null);
convertView.setTag(row);
}else{
TextView viewTitre = (TextView)row.findViewById(R.id.titre);
TextView viewAuteur = (TextView)row.findViewById(R.id.auteur);
TextView viewDate = (TextView)row.findViewById(R.id.date);
ImageView viewLogo = (ImageView)row.findViewById(R.id.category_logo);
viewTitre.setText(getItem(position).getTitle());
viewAuteur.setText(getItem(position).getCreator());
viewDate.setText(getItem(position).getDate());
Drawable drawLogo = context.getResources().getDrawable(R.drawable.logocat);
viewLogo.setImageDrawable(drawLogo);
}
}

I had this similar kind of issue. I also found that without scrolling manually to the last of the list all views were not created. All items were null except visible items.So, I had to scroll down to the last of the list programmatically.
I have extended MyAdapter from BaseAdapter class.
mAdapter = new MyAdapter(this, mFinalContactList);
mListView.setAdapter(mAdapter);
To auto scrolling to last with all listview created I have used following lines of code.
mAdapter.notifyDataSetChanged();
mListView.setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);
mListView.smoothScrollToPosition(mFinalContactList.size()-1);
This might help some one who are trying auto scroll to the last.
N.B. mListView.setSelection(position); method only can point the last list item if we set the position to last. But can not populate the list item from forst to last.
Thank you
