InfoWindow containing a ListView maps v2 android - android

I have been trying to implement a ListView inside a custom Google maps info window.
How do I get the ListView to populate and show?
I have the info window showing with the other relevant information by creating this InfoWindowAdapter
class CustomInfoWindowAdapter implements InfoWindowAdapter {
#Override
public View getInfoContents(Marker arg0) {
// Getting view from the layout file info_window_layout
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
View v = (View)inflater.inflate(R.layout.custom_info_window, null);
if (clickedClusterItem != null) {
//This is the area that does not show
ListView listitemview = (ListView) v.findViewById(R.id.ListItems);
InfoItemAdapter customadapter = new InfoItemAdapter(MapActivity.this,clickedClusterItem.ListItems);
listitemview.setAdapter(customadapter);
//Getting reference to the TextView to set footer
TextView footer = (TextView) v.findViewById(R.id.InfoFooter);
footer.setText(getResources().getString(R.string.info_window_footer));
//Getting reference to the TextView to set Title
TextView name = (TextView) v.findViewById(R.id.LocationName);
name.setText(clickedClusterItem.Name);
}
// Returning the view containing InfoWindow contents
return v;
}
#Override
public View getInfoWindow(Marker arg0) {
// TODO Auto-generated method stub
return null;
}
}
The Custom adapter for each item in the list
public class InfoItemAdapter extends ArrayAdapter<ListItem> {
private final Context context;
private final ArrayList<ListItem> listitems;
public InfoItemAdapter(Context context, ArrayList<ListItem> listitems) {
super(context, R.layout.custom_info_window_list_item);
this.context = context;
this.listitems= listitems;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.custom_info_window_list_item, parent, false);
TextView firstLine = (TextView) rowView.findViewById(R.id.firstLine);
firstLine.setText(listitems.get(position).getDescription());
TextView secondLine = (TextView) rowView.findViewById(R.id.secondLine);
secondLine.setText(listitems.get(position).getTimeString());
// Set the icon
ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
imageView.setImageResource(listitems.get(position).getIcon());
return rowView;
}
}
These are my XML layouts
The parent view which contains the List and other properties which are populated

This poster seems to have accomplished it but I cant seem to get it to work. I do not need click functionality on the list android marker custom infowindow

OK, I could not get the list to populate within the info window.
I ended up getting my desired result by building the new views programatically within the CustomInfoWindowAdapter -> getInfoContents method.
This is my updated CustomInfoWindowClass which does work. If anyone comes across this who knows how to implement a list on a info window your input would be appreciated.
class CustomInfoWindowAdapter implements InfoWindowAdapter {
#Override
public View getInfoContents(Marker arg0) {
// Getting view from the layout file info_window_layout
LayoutInflater inflater = (LayoutInflater) MapActivity.this.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
View v = (View)inflater.inflate(R.layout.custom_info_window, null);
LinearLayout view = (LinearLayout)v;
if (clickedClusterItem != null) {
if(clickedClusterItem.ListItems.size()>0){
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
lp.setMargins(10, 0, 10, 0);
for(ListItem listItem : clickedClusterItem.ListItems){
TextView listitemdesc = new TextView(MapActivity.this);
TextView listitemtime = new TextView(MapActivity.this);
listitemdesc.setText(hh.getDescription());
listitemdesc.setTextSize(18f);
listitemtime.setTextSize(12f);
listitemtime.setText(hh.getTimeString());
if(Helpers.isActive(listItem))
{
listitemdesc.setTextColor(Color.parseColor("#f7941d"));
listitemtime.setTextColor(Color.parseColor("#f7941d"));
}
else if(Helpers.isCommingSoon(listItem)){
listitemdesc.setTextColor(Color.parseColor("#008fd5"));
listitemtime.setTextColor(Color.parseColor("#008fd5"));
}
else{
listitemdesc.setTextColor(Color.parseColor("#515e64"));
}
listitemdesc.setLayoutParams(lp);
listitemtime.setLayoutParams(lp);
view.addView(listitemdesc);
view.addView(listitemtime);
}
}
//Getting reference to the TextView to set Title
TextView name = (TextView) v.findViewById(R.id.LocationName);
name.setText(clickedClusterItem.Name);
}
// Returning the view containing InfoWindow contents
return v;
}
#Override
public View getInfoWindow(Marker arg0) {
// TODO Auto-generated method stub
return null;
}
}

ListView Inside CardView not Showing its full length

Hellow i've implemented ListView inside the CardView but now what problem i got is, the CardView is not Expanding on Adding list item. Can anybody help me,how to slove the issue? I have gone through different posts on stackoverflow but cannot find the solution :( My code is below
//this is my Listview adapter Class
public class EmploymentHistoryAdapter extends BaseAdapter {
public ArrayList<EmploymentHistory> mEmploymentHistories;

You need to specify certain height for ListView in the xml code. WRAP_CONTENT will not expand your ListView when data is inflated into it. Specify some height like 200dp or something.

Populate list of custom view using ListFragment

I am trying to show elements in a list view using Fragments. I created my custom view as follow
graphical representation of list_row.xml
list_row.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="5dip" >
<!-- ListRow Left sied Thumbnail image -->
<LinearLayout
android:id="#+id/thumbnail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginRight="5dip"
android:padding="3dip" >
<ImageView
android:id="#+id/list_image"
android:layout_width="50dip"
android:layout_height="50dip"
android:contentDescription="#string/image_desc"/>
</LinearLayout>
<!-- Menu name -->
<TextView
android:id="#+id/menu_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/thumbnail"
android:layout_toRightOf="#+id/thumbnail"
android:text="#string/menu_name"
android:textColor="#040404"
android:textSize="15sp"
android:textStyle="bold"
android:typeface="sans" />
<!-- Description -->
<TextView
android:id="#+id/description"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/thumbnail"
android:layout_below="#id/menu_name"
android:layout_marginTop="1dip"
android:layout_toRightOf="#+id/thumbnail"
android:text="#string/description"
android:textColor="#343434"
android:textSize="10sp"
tools:ignore="SmallSp" />
<!-- Price -->
<TextView
android:id="#+id/price"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignTop="#id/menu_name"
android:layout_marginRight="5dip"
android:gravity="right"
android:text="#string/price"
android:textColor="#10bcc9"
android:textSize="10sp"
android:textStyle="bold"

In fragment.xml file, I simply put a list view inside a linear layout
fragment.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ListView>
</LinearLayout>
I have an array of menu objects, that has the necessary fields to populate list_row.xml like menu name, description, price and image. I couldn't find a way to fill fragment.xml's listView with the list_row elements. Any help or idea would be appreciated.
PS: I think in fragment.xml instead of android:id="#+id/listView1" field, I have to write android:id="#id/list" since I'm using ListFragment
I solved my problem (as system32 suggests on comment) creating a CustomArrayAdapter class, and setting it as the adapter for my listView.
First I changed android:id="#+id/listView1" to android:id="#android:id/list" in fragment.xml.
CustomArrayAdapter.java
public class CustomArrayAdapter extends ArrayAdapter<Menu> {
Context context;
public CustomArrayAdapter(Context context, int textViewResourceId, List<Menu> objects) {
super(context, textViewResourceId, objects);
// TODO Auto-generated constructor stub
this.context = context;
}
/*private view holder class*/
private class ViewHolder {
ImageView imageView;
TextView txtMenuName;
TextView txtMenuDesc;
TextView txtPrice;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
Menu rowItem = getItem(position);
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = mInflater.inflate(R.layout.list_row, null);
holder = new ViewHolder();
holder.txtMenuName = (TextView) convertView.findViewById(R.id.menu_name);
holder.txtMenuDesc = (TextView) convertView.findViewById(R.id.description);
holder.txtPrice = (TextView) convertView.findViewById(R.id.price);
holder.imageView = (ImageView) convertView.findViewById(R.id.list_image);
convertView.setTag(holder);
} else
holder = (ViewHolder) convertView.getTag();
holder.txtMenuDesc.setText(rowItem.getDescription());
holder.txtMenuName.setText(rowItem.getName());
holder.txtPrice.setText(String.valueOf(rowItem.getPrice()) + " TL");
//holder.imageView.setImageResource(rowItem.getImageId());
return convertView;
}
}
Then I use it in my Fragment class
public static class Fragment extends ListFragment {
/**
* The fragment argument representing the section number for this
* fragment.
*/
public static final String ARG_SECTION_NUMBER = "section_number";
private ListView listView;
private ArrayList<Menu> menuItems;
private CustomArrayAdapter mAdapter;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment,
container, false);
listView = (ListView) rootView.findViewById(android.R.id.list);
return rootView;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
int num = getArguments().getInt(ARG_SECTION_NUMBER);
// GlobalList is a class that holds global variables, arrays etc
// getMenuCategories returns global arraylist which is initialized in GlobalList class
menuItems = GlobalList.getMenuCategories().get(num).getMenu();
mAdapter = new CustomArrayAdapter(getActivity(), android.R.id.list, menuItems);
listView.setAdapter(mAdapter);
}
}

ListView is showing gapes in list items Android

i am trying to implement listView through setListAdapter and Efficient Adapter. I want that when list is show then the background should not be repeat. My code is repeating the whole layout of list.xml due to which my list item are showing with so much gap.
Right now my list is working like that:
But i want this type of view:
Here is my editText.xml in which i type the word and a list View is opened.
<EditText
android:id="#+id/start_edit"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_gravity="top|left"
android:ems="10"
android:hint="Type to search"
android:paddingLeft="50dp" >
<requestFocus />
</EditText>
this layout is for list.xml :
<RelativeLayout
android:id="#+id/RelativeLayout_list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/blue_cellbar" >
the list.xml file is repeating the layout in Effecient adapter:
here is my code:
listAdapter = new EfficientAdapter2(this);
setListAdapter(listAdapter);
public static class viewHolder2 {
TextView word;
TextView meaning;
ImageView image;
ImageView image_color;
RelativeLayout cell;
}
private class EfficientAdapter2 extends BaseAdapter implements Filterable,OnItemClickListener {
private Context context;
LayoutInflater inflater;
public EfficientAdapter2(Context context) {
this.context = context;
inflater = LayoutInflater.from(context);
}
public int getCount() {
// if(SearchWordString.isEmpty()==false)
// {
return SearchWordString.size();
/// }
//return 0;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
viewHolder2 holder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.list, null);
ViewToUse=parent;
holder = new viewHolder2();
// Log.i("View","is Null");
convertView.setTag(holder);
} else {
//Log.i("View","is not Null");
holder = (viewHolder2) convertView.getTag();
}
holder.cell = (RelativeLayout) convertView
.findViewById(R.id.RelativeLayout_list);
return convertView;
}

I hope you have not provide android:dividerHeight attribute in your layout file under <ListView/>
If so please remove it.
this problem occurs when you have set the adapter class xml, parent root
match_content instead of wrap_content.
set the root content height wrap_content
As i can see in adapter layout there is no parent root like relative, linearlayout, Framelayout and ConstraintLayout etc.

getView() method of ArrayAdapter repeats first two or three items in list

I extended an ArrayAdapter with an overridden getView() method to fill my ListView object, but the adapter will grab the first two or three objects from the ArrayList I pass to it, then just repeat those in seemingly random order for the entire length of the list. Furthermore, when I scroll up and down in the ListView, some rows change from one list item to another. The ArrayList<Credit> object gets populated from a JSONObject, and to the best of my knowledge is correct prior to being passed into the ArrayAdapter.
My custom ArrayAdapter
private class CreditArrayAdapter extends ArrayAdapter<Credit> {
private ArrayList<Credit> credits;
private int creditCount;
public CreditArrayAdapter(Context ctx, int textViewResourceId, List<Credit> items) {
super(ctx, textViewResourceId, items);
credits = (ArrayList<Credit>) items;
creditCount = credits.size();
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.list_item_movie_medium, null);
Credit current = credits.get(position);
Log.d(tag, "current credit: " + current.toString());
ImageView creditPicture = (ImageView) v.findViewById(R.id.image_poster_thumbnail);
try {
creditPicture.setImageBitmap(current.getPosterSmall());
} catch(Exception e) {
Log.d(tag, "failed to set cast member picture");
e.printStackTrace();
}
TextView castMemberName = (TextView) v.findViewById(R.id.text_credit_info);
castMemberName.setText(current.toString());
}
return v;
}
#Override
public int getCount() {
return creditCount;
}
}
being called by:
appearsIn = (ListView) findViewById(R.id.listview_appears_in);
List<Credit> credits = searcher.getCreditsByPersonId(personId);
CreditArrayAdapter creditAdapter = new CreditArrayAdapter(getBaseContext(), R.layout.list_item_movie_medium, credits);
creditAdapter.notifyDataSetChanged();
appearsIn.setAdapter(creditAdapter);

android:layout_weight="1"/>
</LinearLayout>
My list item layout:
<?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="fill_parent"
android:orientation="horizontal">
<ImageView android:id="#+id/image_poster_thumbnail"
android:layout_height="wrap_content"
android:layout_width="wrap_content"/>
<TextView android:id="#+id/text_credit_info"
android:layout_height="wrap_content"
android:layout_width="fill_parent"/>
</LinearLayout>
change the getView like this:
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.list_item_movie_medium, null);
}
Credit current = credits.get(position);
Log.d(tag, "current credit: " + current.toString());
ImageView creditPicture = (ImageView) v.findViewById(R.id.image_poster_thumbnail);
try {
creditPicture.setImageBitmap(current.getPosterSmall());
} catch(Exception e) {
Log.d(tag, "failed to set cast member picture");
e.printStackTrace();
}
TextView castMemberName = (TextView) v.findViewById(R.id.text_credit_info);
castMemberName.setText(current.toString());
return v;
}
Your problem was you were not doing all the code you needed to set the View object correctly when convertView was != null.
Use this snippet:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.list_item_movie_medium, null);
}
Credit current = credits.get(position);
Log.d(tag, "current credit: " + current.toString());
ImageView creditPicture = (ImageView) v.findViewById(R.id.image_poster_thumbnail);
try {
creditPicture.setImageBitmap(current.getPosterSmall());
} catch(Exception e) {
Log.d(tag, "failed to set cast member picture");
e.printStackTrace();
}
TextView castMemberName = (TextView) v.findViewById(R.id.text_credit_info);
castMemberName.setText(current.toString());
return v;
}
try adjust your xml layout on anyone place that references the height, because the android will do a measure to draw eachtime and will redraw the cell up again.
Try use on listview match_parent and on cell at row an exactly height.
sorry my bad english.

android grid view display caption below each grid

I want to display some text below each grid image.
Please see my code below.
Please help me in finding why its not working
I am getting the images properly displayed but no text
if i try to display text within image its coming
so it should be something with the layout defined. but i am not able to debug
adaptor code :
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.griditems, null);
holder = new ViewHolder();
holder.text1 = (TextView) convertView
.findViewById(R.id.grid_item_text);
Log.i(TAG, holder.text1.toString());
holder.image = (ImageView) convertView
.findViewById(R.id.grid_item_image);
// if it's not recycled, initialize some attributes
holder.image.setImageResource(gridItemIds[position]);
holder.text1.setText(gridTitles[position]);
//holder.image.setScaleType(ImageView.ScaleType.FIT_XY);
// holder.image.setPadding(20, 20, 20, 20);
convertView.setLayoutParams(new GridView.LayoutParams(Utils
.getLayoutParameter(), Utils.getLayoutParameter()));
holder.image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
}
});
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
return convertView;
}
static class ViewHolder {
TextView text1;
ImageView image;
}

I used your xml but with a simple array adapter that I wrote and everything work perfectly, try to replace your adapter with mine and let me know, thanks.
class ItemsAdapter extends ArrayAdapter<String> {
public ItemsAdapter(Context context, List<String> list) {
super(context, R.layout.griditems, list);
}
#Override
public View getView(final int position, View row, final ViewGroup parent) {
final String item = getItem(position);
ItemWrapper wrapper = null;
if (row == null) {
row = getLayoutInflater().inflate(R.layout.griditems, parent, false);
wrapper = new ItemWrapper(row);
row.setTag(wrapper);
} else {
wrapper = (ItemWrapper) row.getTag();
}
wrapper.refreshData(item);
return row;
}
}
static class ItemWrapper {
TextView text;
ImageView img;
public ItemWrapper(View row) {
text = (TextView) row.findViewById(R.id.grid_item_text);
img = (ImageView) row.findViewById(R.id.grid_item_image);
}
public void refreshData(String item) {
img.setImageResource(R.drawable.image_1);
text.setText(item);
}
}
Also try using RelativeLayout too, placing the TextView underneath the ImageView by using
android:layout_below="#id/grid_item_image"
It'll place it underneath the image, however, if you have the option to use the Graphical Layout, dragging it where you want it in conjunction with the image will set all the parameters for you instead of typing them out.
