ListFragment doesn't show changes in present time

All! I'am new in android app. Now I have some problem. I can't see the result of changing list right away (after updating listView in my ListFragment).
For example, i called method addNewItem and I didn't see any changes on the screen. But if I touch ListFragment I will see all my changes.
ListFragment:
public class PointsListFragment extends ListFragment {
PlaceItemsAdapter adapter;
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
adapter = new PlaceItemsAdapter(
getActivity(), R.layout.place_list_item,
new ArrayList<PlaceItem>());
setListAdapter(adapter);
adapter.notifyDataSetChanged();
}
public void addNewItem(int id, String address) {
adapter.items.add(new PlaceItem(id, address));
adapter.notifyDataSetChanged();
}
private class PlaceItemsAdapter extends ArrayAdapter<PlaceItem> {
private final int viewResourceId;
final public ArrayList<PlaceItem> items;
#Override
public int getCount() {
return items.size();
}
#Nullable
#Override
public PlaceItem getItem(int position) {
return items.get(position);
}
public PlaceItemsAdapter(Context context, int viewResourceId, ArrayList<PlaceItem> items) {
super(context, viewResourceId, items);
this.items = items;
this.viewResourceId = viewResourceId;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(viewResourceId, null);
}
PlaceItem placeItem = getItem(position);
TextView placeIdTextView = (TextView) v.findViewById(R.id.placeId);
placeIdTextView.setText(String.valueOf(placeItem.getId()));
TextView placeAddressView = (TextView) v.findViewById(R.id.placeAddress);
placeAddressView.setText(placeItem.getAddress());
if (selectedValue == position) {
v.setBackgroundResource(R.drawable.active_item);
}
return v;
}
}
}

Image Example

Thank you, ALL! I found the answer! I called method from another class (no Activity or Fragment). And now I also call method from another class, but i do it through Handler. And it really works fine now!
Something like that:
Message msg = mainActivityHandler.obtainMessage(MainActivity.NEW_MESSAGE, someObjectToAdd);
mainActivityHandler.sendMessage(msg);

Get view from ListView row

Basically all I'm trying to do is have a button appear in a row, when the row is selected. I have tried many methods, and they all seem to work including the one below...I get the ImageView but calling setVisibility() on it does nothing:
ListFragment
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
setSellButton();
}
public View getViewForPosition(int position){
int relativePos = position - listview.getFirstVisiblePosition();
if( relativePos < 0 || relativePos > listview.getChildCount()){
return null;
}
return listview.getChildAt(relativePos);
}
public void setSellButton() {
View x = getViewForPosition(Constants.lastSelection);
ImageView y = (ImageView)x.findViewById(R.id.ivSell);
y.setVisibility(View.VISIBLE);
}
No errors, and debug shows that everything is right in setSellButton() but setVisibility() never works. Is this something I can only do in the adapter? Thanks!

Well. First of all allow me to adapt your row xml. It's better to use RelativeLayout instead of LinearLayout. It's more flexible.
row_layout.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:background="#drawable/thelist"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:minHeight="#dimen/listView_minHeight">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/ivStar"
android:contentDescription="#string/list_item_image_desc"
android:layout_gravity="center_vertical"
android:layout_centerVertical="true"
android:src="#drawable/liststar" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/ivStar"
android:layout_toEndOf="#+id/ivStar"
android:layout_alignParentTop="true"
android:id="#+id/label"
android:text="New Text"
android:textSize="15sp"
android:layout_marginLeft="12dp"
android:layout_marginRight="12dp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:textSize="13sp"
android:id="#+id/tvValue"
android:layout_below="#+id/label"
android:layout_toRightOf="#+id/ivStar"
android:layout_toEndOf="#+id/ivStar"
android:layout_marginLeft="12dp"
android:layout_marginRight="12dp" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/ivSell"
android:src="#drawable/coin"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_centerVertical="true"
android:visibility="invisible" />
</RelativeLayout>
You're probably subclassing BaseAdapter. What you'll have to do is to create a method there to change the visibility of your ImageView. Then when you have your item clicked, you can get the adapter and call that method.
CustomAdapter.java
public class CustomAdapter extends BaseAdapter {
private Context context_;
private ArrayList<YourDataHolder> items;
private YourDataHolder lastHolder = null;
private final String LOG_TAG = CustomAdapter.class.getSimpleName();
public CustomAdapter(Context context, ArrayList<YourDataHolder> items) {
this.context_ = context;
this.items = items;
}
#Override
public int getCount() {
return items.size();
}
#Override
public Object getItem(int i) {
return items.get(i);
}
#Override
public long getItemId(int i) {
return i;
}
#Override
public View getView(int position, View convertView, ViewGroup viewGroup) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
context_.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.row_layout, null);
}
final TextView tv_label = (TextView) convertView.findViewById(R.id.label);
final TextView tv_value = (TextView) convertView.findViewById(R.id.tvValue);
final ImageView iv_star = (ImageView) convertView.findViewById(R.id.ivSell);
YourDataHolder holder = items.get(position);
tv_label.setText(holder.getLabel());
tv_value.setText(holder.getValue());
if (holder.isImageVisible() && iv_star.getVisibility() == ImageView.INVISIBLE) {
iv_star.setVisibility(ImageView.VISIBLE);
}
else if (iv_star.getVisibility() == ImageView.VISIBLE) {
iv_star.setVisibility(ImageView.INVISIBLE);
}
return convertView;
}
public void onItemSelect(int position) {
if (position < items.size()) {
YourDataHolder holder = items.get(position);
holder.setVisibility(true);
if (lastHolder != null) {
lastHolder.setVisibility(false);
}
lastHolder = holder;
}
}
}
Assuming you're using a data holder like this one:
YourDataHolder.java
public class YourDataHolder {
private String label;
private String value;
private boolean isVisible;
public YourDataHolder(String label, String value) {
this.label = label;
this.value = value;
isVisible = false;
}
public String getLabel() {
return label;
}
public String getValue() {
return value;
}
public boolean getVisibility() {
return isVisible;
}
public void setVisibility(boolean isVisible) {
this.isVisible = isVisible;
}
}
And then, on your onItemClick(), do the magic.
YourFragment.java
private CustomAdapter adapter;
// Rest of the Fragment. Where you create the adapter, and assign it to the ListView.
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
adapter.onItemSelect(position);
adapter.notifyDataSetChanged();
}

My guess is, that after the click on the item you need to call the notifyDataSetChanged method on the adapter. And then render the button on the selected list view item.

It is something that I would do in the adapter, having direct access to the imageview would make the process easier. I previously attempted to do it from the listview level and was unable to do to the conditions I had setup.

Android custom ListView layout problems

Hi guys, I tried to learn how to use custom ListView by this page
It works fine but I have problems with another options.
Cannot set margin to listItems
Cannot set backgro
Cannot set OnItemClickListener
1# Margin
First of all I'm trying to set margin between list items but nothing works. I try to set margin on RelativeLayout in rowlayout.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="75dp"
android:background="#drawable/rounded"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
>
2# Background
I want to set background on whole screen under listView. I think I put black color on every View in every xml I found but nothing affect the background. I can change background of single list items, that's all.
android:background="#000000"
3#OnItemClickListener
My last problem is that I'm not able to set onItemClickListener. I have no idea how to set it if I don't have simply ListView but RelativeLayout with TextView etc.
I guess I have to use
setOnClickListener(new OnClickListener()
and after that
public void onClick(View arg0) {
but I have no idea on which View I have to use this method.

Looks like you are half way there in your activity.
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
MyAdapter adapter = new MyAdapter(this, generateData());
ListView listView = (ListView) findViewById(R.id.menu);
listView.setAdapter(adapter); if extending Activity
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
onItemClick(AdapterView<?> parent, View view, int position, long id)
{
//You now have the position but you will need to get your model list and use .get(position) and cast it to Model to get access to it.
}
});
}

//First define your list view item xml… something like this.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#color/white"
android:layout_marginTop="10dp"
android:padding="10dp" >
<TextView
android:id="#+id/item1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#color/custom_blue"
android:text="TextView" />
<TextView
android:id="#+id/item2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:textColor="#color/custom_grey"
android:text="TextView" />
</LinearLayout>
//Then you define your list list adapter.
public class MyListAdapter extends ArrayAdapter<MyModel> {
private Context context;
private ArrayList<MyModel> myModel;
public MyListAdapter(Context context, ArrayList<MyModel> myModelList) {
super(context, R.id.icon, myModelList);
this.context = context;
this.myModelList = myModelList;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = null;
View rowView = convertView;
TextView myItemName = (TextView)rowView.findViewById(R.id.item1);
TextView myItemTitle = (TextView)rowView.findViewById(R.id.item2);
//use your models getters/setters
myItemName.setText(myModelList.get(position).getItemTitle());
myItemTitle.setText(myModelList.get(position).getItemName());
return rowView
}
}
//Now use both the list adapter and list item in your ListFragment or ListActivity.
ArrayList<MyModel> myModelList = new ArrayList<MyModel>();
MyListAdapter myApt = new MyListAdapter(this, myModelList);
setListAdapter(myApt);
//For clicking on the items:
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// ListView Clicked item value
String itemValue = l.getItemAtPosition(position).toString();
doSomethingWihtMyItemMethod(position);
}
/* You can customize your list item anyway you like, just be aware of screen real estate when doing so.Hope this helps. */

ArrayAdapter getView method trigger only first element

I try to use ListFragment to create a list.I created custom array adapter for listfragment. I can see only first item on my activiy When I launch my project.But I've noticed when I drag and drop fist item I can see second item on one line.You can see below my fragment layout and list item layout.Also I attached my custom adapter class.Thanks in advance.
Fragment layout

My custom array adapter
public class MenuListAdapter extends ArrayAdapter<MainMenuInfo> {
private List<MainMenuInfo> menuList;
private Context context;
private int layoutResourceID;
public MenuListAdapter(Context context, int layoutResourceID, List<MainMenuInfo> menuList) {
super(context, layoutResourceID, menuList);
this.context = context;
this.menuList = menuList;
this.layoutResourceID = layoutResourceID;
}
#Override
public int getCount() {
return menuList.size();
}
#Override
public MainMenuInfo getItem(int position) {
return menuList.get(position);
}
#Override
public long getItemId(int position) {
return menuList.get(position).get_ID();
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(layoutResourceID, null);
}
MainMenuInfo menu = menuList.get(position);
ImageView imgMenu = (ImageView) view.findViewById(R.id.imgMenu);
if (menu.getImageName() != null) {
int r = view.getResources().getIdentifier(menu.getImageName(), "drawable", context.getPackageName());
if (r > 0) {
imgMenu.setImageResource(r);
}
}
TextView txtMenu = (TextView) view.findViewById(R.id.txtMenu);
txtMenu.setText(menu.getMenuName());
return view;
}
}

My problem is solved.There is no error in the above code.My fault enter incorrect value in the setDividerHeight property.Therefore my listview can not show other items.Thanks.

onItemClickListener in listview doesn't work

I'm trying to implement a listView using a customized arrayAdapter. I can see my list but, when I try to choose an option of the list, my implemented method onItemClick doesn't work. I've seen similar question here in StackOverflow, but none of the provided solutions work for me... I've tried with android:descendantFocusability="blocksDescendants", with android:clickable="false" and android:focusable="false" for the elements of each row of my list, and I've also tried making the MainActivity.java to implement onItemClick, but it doesn't work. I know I must have a mistake in my code, but I can't find it...
Here is my code:

Can anyone help me?
Thank you in advance!

Your code looks good except for the item_elements.xml. Views in there are clickable and/or focusable.
These two lines, part of the to must be removed in order to get your onItemClickekdListener called:
android:clickable="true"
android:focusable="true"
android:descendantFocusability="blocksDescendants"
The other android:clickable and android:focusable attributes throughout your item_elements.xml are unnecessary, but they should not cause your problem.
