I am working on an android app and using Spinner at many places in my app.
What I want is to change the background color of the selected item of spinner, so that one can easily identify which item is currently selected.
I have already checked this link Setting background color for Spinner Item on selection but doing so will change the selected textview background color but do not change its color in dropdown list and I want to change the background color of the selected textview when I will see the dropdown list.
I want to change the color of selected item in list not on spinner, please see the image below.
How can I do this? Please, can someone help me here?.
Thanks a lot in advanced.
You need to implement below method in your adapter class:
It will help you:
int selectedItem = -1;
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, list) {
#Override
public View getDropDownView(int position, View convertView, ViewGroup parent)
{
View v = null;
v = super.getDropDownView(position, null, parent);
// If this is the selected item position
if (position == selectedItem) {
v.setBackgroundColor(Color.BLUE);
}
else {
// for other views
v.setBackgroundColor(Color.WHITE);
}
return v;
}
};
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mySpinner.setAdapter(dataAdapter);
Now on item selected in spinner put below
selectedItem = position;
Here is solution via XML:
Spinner looks like:
<Spinner
android:id="#+id/settingsSleepingTimePicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/spinner_main_button"
android:popupBackground="#color/colorPrimary"
android:textColor="#android:color/white"
android:textSize="20sp"/>
While creating spinner set setDropDownViewResource as custom layout:
adapter.setDropDownViewResource(R.layout.spinner_item);
And spinner_item.xml looks like:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/spinner"
android:textColor="#ffffff"
android:textSize="20sp" />
And finally we set #drawable/spinner like this:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/colorPrimaryLight" android:state_hovered="true" />
<item android:drawable="#color/colorPrimaryLight" android:state_selected="true" />
</selector>
Hope my answer will be helpfull!
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="colorControlNormal">#color/spinner_background</item>
</style>
Define Spinner_background color in color folder..
Try creating a selector in the drawable, something like,
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="false" android:drawable="#color/colorPrimary" />
<item android:drawable="#android:color/transparent" />
</selector>
And set the spinner background as
android:background="#drawable/spinner_selector"
I've searched the internet for a proper solution to do this without hardcoding the background behaviour in java code.
You can achieve this (setting the selected item background color) using drawables.
What you need to do it set the dropdownViewResource to a custom layout. That layout should look something like this:
<?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:background="#drawable/spinner_item_background"
android:gravity="left"
android:padding="8dp" />
In spinner_item_background.xml, you can define a background for each item state. For example, if you want to have a ripple effect on press, but a solid effect when selected, you can try this:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Activated state is the selected item -->
<item android:state_activated="true" android:drawable="#00ff00"/>
<!-- Pressed state is the one the user is interacting with -->
<item android:state_pressed="true" android:drawable="#00ff00"/>
<!-- The rest of the items -->
<item android:drawable="#ffffff"/>
</selector>
Create an int variable public static int posOfItemSpinnerSelected in your Activity:
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
posOfItemSpinnerSelected=position;
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
and in your adapter insert this code
if(position== YourActivity.posOfItemSpinnerSelected){
textView.setBackgroundColor(ContextCompat.getColor(mActivity,R.color.item_spinner_selected));
} else {
textView.setBackgroundColor(ContextCompat.getColor(mActivity,R.color.white));
}
I want to update the layout of some items a in a ListView in an android app widget if a trigger is given. So I implemented below in getView() method in RemoteViewsService.RemoteViewsFactory.
public RemoteViews getViewAt(int position) {
...
int remoteViewId;
if (some condition) {
remoteViewId = R.layout.highlighted_item;
} else {
remoteViewId = R.layout.item;
}
RemoteViews rv = new RemoteViews(mContext.getPackageName(), remoteViewId);
This code works when the widget is loaded for the first time, but when updated using notifyAppWidgetViewDataChanged the layout persists and is not changed. How can I update xml layout used for a ListView item?
Change background
If my assumption is right and you are trying to highlight a list item by changing the background color or something similar I´d suggest to use a selector drawable instead of changing the layout programmatically:
drawable/list_item_selector.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_activated="true"
android:drawable="#drawable/list_item_background_activated" />
<item
android:state_pressed="true"
android:drawable="#drawable/list_item_background_pressed" />
<item
android:drawable="#drawable/list_item_background" />
</selector>
drawable/list_item_background.xml
drawable/list_item_background_pressed.xml
drawable/list_item_background_activated.xml
Define such a drawable for each state in the selector and replace the 'color' with an appropriate color resource.
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="color" />
<stroke
android:width="1dp"
android:color="color" />
</shape>
Apply the list selector to the ListView in the widget´s layout:
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:listSelector="#drawable/list_item_selector" />
I use this for my own widget and it works perfectly.
For further information on state lists see this link.
Change entire layout
In order to change the entire layout try the following:
public class WidgetListProvider implements RemoteViewsFactory {
private boolean alternateLayout = 1;
#Override
public void onDataSetChanged() {
alternateLayout = alternateLayout == 1 ? 2 : 1;
}
#Override
public RemoteViews getViewAt(int position) {
final RemoteViews rv = new RemoteViews(_context.getPackageName(),
alternateLayout == 1 ? R.layout.list_row : R.layout.list_row2);
[...]
return rv;
}
#Override
public int getViewTypeCount() {
return 2;
}
[...]
}
Important: Note getViewTypeCount() - Because you use two different layouts, you have to return 2 here. If you return 1, a loading view will be displayed for the second layout.
I have a custom ListView in a tablet app where there's a ListView on the left and detailed fragment on the right, when you select an Item on the left from the listView I want it to be highlighted and stay highlighted (I did this part) but when I scroll down to the bottom of the list and back and due to The recycling of views it forgets the highlighting, how can I do it in a different way?
Here's the code I used in the adapter for the ListView:
protected LinearLayout selectedItem;
protected LinearLayout selectedItemPosition = -1;
.
.
.
#Override
public int getViewTypeCount() {
return 3; // I have 3 types of list Items, this part is working fine..
}
public int getItemViewType(int pos) {
// This part works fine too
}
.
.
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
.
.
.
if (selectedItemPosition == pos) {
holder.listItem.setSelected(true);
}
final LinearLayout listItem = holder.listItem;
holder.listItem.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (clickCallback != null) {
if (activateOnClick) {
if (selectedItemPosition > -1) {
selectedItem.setSelected(false);
}
selectedItemPosition = pos;
listItem.setSelected(true);
selectedItem = listItem;
}
clickCallback.callback(NewsItems.get(pos));
}
}
});
You can try to create custom selector for listview item - listview_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_enabled="true"
android:state_pressed="true" android:drawable="#color/yourColor" />
<item android:state_enabled="true"
android:state_focused="true" android:drawable="#color/yourColor" />
<item android:state_enabled="true"
android:state_selected="true" android:drawable="#color/yourColor" />
<item
android:drawable="#color/yourColor" />
</selector>
And then, use
listView.setSelector(R.drawable.listview_selector);
I want to know on how I can change the background color of the selected item on my listView. I only want to change the specific item clicked by the user, meaning if the user clicks another item it will be the one which is highlighted. Well since I want it to keep simple as possible and use the default android listview I used this code instead:
record_list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
try{
for (int ctr=0;ctr<=record_items.length;ctr++){
if(i==ctr){
record_list.getChildAt(ctr).setBackgroundColor(Color.CYAN);
}else{
record_list.getChildAt(ctr).setBackgroundColor(Color.WHITE);
}
}
}
catch (Exception e){
e.printStackTrace();
}
Log.v("Selected item",record_list.getItemAtPosition(i));
}
});
Ok this one is working but the problem is that it's slow. Now I want to know if there's any other way around that I can do which will give the same output as I made.
I tried using record_list.getSelectedView().setBackgroundColor(Color.CYAN); but it gives me a null pointer exception.
I also tried the selector.xml but it also didn't do the trick.
Furthermore, there is one properties here on ListView which is called listSelector. It's a drawable as said by the documentation "Drawable used to indicate the currently selected item in the list." I also believe that this should do the trick and yes it do the trick on my emulator but not on my galaxy tab. I also tried the other methods but nothing works as I wanted it to be.
You can keep track the position of the current selected element:
OnItemClickListener listViewOnItemClick = new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapter, View arg1, int position, long id) {
mSelectedItem = position;
mAdapter.notifyDataSetChanged();
}
};
And override the getView method of your adapter:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final View view = View.inflate(context, R.layout.item_list, null);
if (position == mSelectedItem) {
// set your color
}
return view;
}
For me it did the trick.
You can use a selector. Change the colors values and modify the below according to your needs.
bkg.xml in drawable folder
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="#drawable/pressed" />
<item android:state_focused="false"
android:drawable="#drawable/normal" />
</selector>
pressed.xml in drawable folder
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FF1A47"/> // color
<stroke android:width="3dp"
android:color="#0FECFF"/> // border
<padding android:left="5dp"
android:top="5dp"
android:right="5dp"
android:bottom="5dp"/>
<corners android:bottomRightRadius="7dp" // for rounded corners
android:bottomLeftRadius="7dp"
android:topLeftRadius="7dp"
android:topRightRadius="7dp"/>
</shape>
normal.xml in drawable folder
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFFFFF"/>
<stroke android:width="3dp"
android:color="#0FECFF" />
<padding android:left="5dp"
android:top="5dp"
android:right="5dp"
android:bottom="5dp"/>
<corners android:bottomRightRadius="7dp"
android:bottomLeftRadius="7dp"
android:topLeftRadius="7dp"
android:topRightRadius="7dp"/>
</shape>
Set the background drawable to listview custom layout to be inflated for each row
I recommend using a custom listview with a custom adapter.
android:background="#drawable/bkg"
If you have not used a custom adapter you can set the listselector to listview as below
android:listSelector="#drawable/bkg"
Define variable
private ListView mListView;
Initialize variable
mListView = (ListView)findViewById(R.id.list_view);
OnItemClickListener of listview
mListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adpterView, View view, int position,
long id) {
for (int i = 0; i < mListView.getChildCount(); i++) {
if(position == i ){
mListView.getChildAt(i).setBackgroundColor(Color.BLUE);
}else{
mListView.getChildAt(i).setBackgroundColor(Color.TRANSPARENT);
}
}
}
});
Build and run the project - Done
If you want to have the item remain highlighted after you have clicked it, you need to manually set it as being selected in the onItemClick listener
Android ListView selected item stay highlighted:
myList.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
view.setSelected(true); // <== Will cause the highlight to remain
//... do more stuff
}});
This assumes you have a state_selected item in your selector:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="true" android:state_pressed="true" android:drawable="#color/red" />
<item android:state_enabled="true" android:state_focused="true" android:drawable="#color/red" />
<item android:state_enabled="true" android:state_selected="true" android:drawable="#color/red" />
<item android:drawable="#color/white" />
</selector>
Method 1:
Update ListView in the your xml layout activity/fragment:
<ListView
...
android:choiceMode="singleChoice"
android:listSelector="#android:color/darker_gray"
/>
That's it, you're done!
If you want a programmatic way to handle this then use method 2...
Method 2:
If you're using a ListFragment you can override onListItemClick(), using the view to set the colour. Save the current View selected to reset the colour of the last selection.
Please note, this only works on listviews that fit on one screen, as the view is recycled.
public class MyListFragment extends ListFragment {
View previousSelectedItem;
...
#Override
public void onListItemClick(ListView parent, View v, int position, long id) {
super.onListItemClick(parent, v, position, id);
if (previousSelectedItem!=null) {
previousSelectedItem.setBackgroundColor(Color.WHITE);
}
previousSelectedItem=v;
v.setBackgroundColor(Color.BLUE);
}
}
First you can create selector xml file like below in your drawable folder drawable/list_item_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_activated="true">
<shape android:shape="rectangle">
<solid android:color="#333333" />
<padding android:left="5dp" android:right="5dp" />
</shape></item>
<item><shape android:shape="rectangle">
<solid android:color="#222222" />
</shape></item>
</selector>
And then in your listview specify background as
android:background="#drawable/list_item_selector"
For those wondering what EXACTLY needs to be done to keep rows selected even as you scroll up down. It's the state_activated The rest is taken care of by internal functionality, you don't have to worry about toggle, and can select multiple items. I didn't need to use notifyDataSetChanged() or setSelected(true) methods.
Add this line to your selector file, for me drawable\row_background.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="#android:color/holo_blue_light"/>
<item android:state_enabled="true" android:state_pressed="true" android:drawable="#android:color/holo_blue_light" />
<item android:state_enabled="true" android:state_focused="true" android:drawable="#android:color/holo_blue_bright" />
<item android:state_enabled="true" android:state_selected="true" android:drawable="#android:color/holo_blue_light" />
<item android:state_activated="true" android:drawable="#android:color/holo_blue_light" />
<item android:drawable="#android:color/transparent"/>
</selector>
Then in layout\custom_row.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dip"
android:background="#drawable/row_background"
android:orientation="vertical">
<TextView
android:id="#+id/line1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
For more information, I'm using this with ListView Adapter, using
myList.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
and
myList.setMultiChoiceModeListener(new MultiChoiceModeListener()...
from this example: http://www.androidbegin.com/tutorial/android-delete-multiple-selected-items-listview-tutorial/
Also, you (should) use this structure for your list-adapter coupling: List myList = new ArrayList();
instead of: ArrayList myList = new ArrayList();
Explanation: Type List vs type ArrayList in Java
Simplest way I've found:
in your activity XML add these lines:
<ListView
...
android:choiceMode="singleChoice"
android:listSelector="#666666"
/>
or programatically set these properties:
listView.setSelector(Drawable selector)
listView.setSelector(int resourceId)
My particular example:
<ListView
android:choiceMode="singleChoice"
android:listSelector="#666666"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/listView"/>
thanks to AJG:
https://stackoverflow.com/a/25131125/1687010
View updateview;// above oncreate method
listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (updateview != null)
updateview.setBackgroundColor(Color.TRANSPARENT);
updateview = view;
view.setBackgroundColor(Color.CYAN);
}
});
I'm also doing the similar thing: highlight the selected list item's background (change it to red) and set text color within the item to white.
I can think out a "simple but not efficient" way:
maintain a selected item's position in the custom adapter, and change it in the ListView's OnItemClickListener implement:
// The OnItemClickListener implementation
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
mListViewAdapter.setSelectedItem(position);
}
// The custom Adapter
private int mSelectedPosition = -1;
public void setSelectedItem (int itemPosition) {
mSelectedPosition = itemPosition;
notifyDataSetChanged();
}
Then update the selected item's background and text color in getView() method.
// The custom Adapter
#Override
public View getView(int position, View convertView, ViewGroup parent) {
...
if (position == mSelectedPosition) {
// customize the selected item's background and sub views
convertView.setBackgroundColor(YOUR_HIGHLIGHT_COLOR);
textView.setTextColor(TEXT_COLOR);
} else {
...
}
}
After searching for a while, I found that many people mentioned about to set android:listSelector="YOUR_SELECTOR". After tried for a while, I found the simplest way to highlight selected ListView item's background can be done with only two lines set to the ListView's layout resource:
android:choiceMode="singleChoice"
android:listSelector="YOUR_COLOR"
There's also other way to make it work, like customize activatedBackgroundIndicator theme. But I think that would be a much more generic solution since it will affect the whole theme.
use the below xml as listitem background it will solve all the issues.
The selected will be highlighted though you scrolled down.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#android:color/holo_orange_dark" android:state_pressed="true"/>
<item android:drawable="#android:color/holo_green_light" android:state_selected="true"/>
<item android:drawable="#android:color/holo_green_light" android:state_activated="true"/>
Thanks,

I know this is a old question, but i give a simple solution for this need (without loops!):
//On your adapter create a variable:
private View lastSelectedItem;
//Define the folowing method:
private void toggleBackgroundItem(View view) {
if (lastSelectedItem != null) {
lastSelectedItem.setBackgroundColor(Color.TRANSPARENT);
}
view.setBackgroundColor(getResources().getColor(R.color.colorPrimaryDark));
lastSelectedItem = view;
}
//finally invoque the method onItemClick
lvSac.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
#Override
public void onItemClick (AdapterView < ? > adapterView, View view,int i, long l){
toggleBackgroundItem(view);
}
}
In a ListView set:
android:choiceMode="singleChoice"
Create a selector for a background (drawable/selector_gray.xml):
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/gray" android:state_checked="true" />
<item android:drawable="#color/white" />
</selector>
Add an item for a list:
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:padding="5dp"
android:background="#drawable/selector_gray"
android:textColor="#color/colorPrimary"
tools:text="Your text" />
In a ViewHolder you can inflate this item.
nameofList.getChildAt(position).setBackgroundColor(RED);
worked for me
assume you want one item to be clicked each time. Then this code works well. Let's take the listview name as stlist
stList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
// here i overide the onitemclick method in onitemclick listener
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
//color change
//selected item colored
for(int i=0; i<stList.getAdapter().getCount();i++)
{
stList.getChildAt(i).setBackgroundColor(Color.TRANSPARENT);
}
parent.getChildAt(position).setBackgroundColor(Color.GRAY);
});
This is a simple method that can handle selection even if the list is long as well:
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
Holder holder=new Holder();
View rowView;
rowView = inflater.inflate(R.layout.list_item, null);
//Handle your items.
//StringHolder.mSelectedItem is a public static variable.
if(getItemId(position)==StringHolder.mSelectedItem){
rowView.setBackgroundColor(Color.LTGRAY);
}else{
rowView.setBackgroundColor(Color.TRANSPARENT);
}
return rowView;
}
And then in your onclicklistener:
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
StringHolder.mSelectedItem = catagoryAdapter.getItemId(i-1);
catagoryAdapter.notifyDataSetChanged();
.....
It's very simple. In the constructor of the "OnItemClick" use the parameter "view" which is the second one that represents the listView or GridView's items's view and it becomes the new item's view made by the adapterView it self. So to set new color ONLY to the SELECTED ITEM itself do as the following:
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l){
//view is instead of the view like textView , ImageView, or whatever
view.setBackgroundColor(Color.green);
}
If you do any different codes to set new color, you will face awkward behaviours like the green color will be applied to the unclicked item.
I am developing a project in which I am required to change the color of text in a ListView on selecting the item of the ListView.
I can change the color of text on selecting the list item but, after a few seconds, the color changes back to what it was previously. I want that color unchanged until I click on another list item. Just look at the following screenshot:
I can get the changed color text in white on click of item of the ListView, but after a few seconds the text changes back to the previous color.
I want to keep the white color of the textview until I click to the other item of the ListView.
The following is my selector file for textviews. For Black text:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true" android:color="#android:color/white"/>
<item android:state_focused="true" android:color="#android:color/white"/>
<item android:state_selected="false" android:color="#android:color/black"/>
</selector>
For Red text:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true" android:color="#android:color/white"/>
<item android:state_focused="true" android:color="#android:color/white"/>
<item android:state_selected="false" android:color="#color/red"/>
</selector>
You need to store the position of the selected item somewhere and override the getView of the adapter so that the background is set correctly when recycling the views. Also you need to tell your adapter to refresh the views when the item gets selected.
If you use ArrayAdapter you can for instance extend it like that:
private class SelectionArrayAdapter extends ArrayAdapter<String> {
private int selectedItem = -1;
public SelectionArrayAdapter(Context context, int resource, String[] objects) {
super(context, resource, objects);
}
public void setSelection(int position) {
selectedItem = position;
notifyDataSetChanged();
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
if(position == selectedItem) {
view.setBackgroundColor(Color.RED);
}
else {
view.setBackgroundColor(Color.TRANSPARENT);
}
return view;
}
}
And when clicking an item you just need to call the setSelection method:
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
adapter.setSelection(position);
}
});
