ListView with multiple lines and hyperlink

ListView with multiple lines and hyperlink - java

I have a listView with multiple lines and I want to add one more line with a link, but i dont know how to do it.
example
this is my code
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>

android:paddingBottom="10dip"
android:paddingLeft="10dip"
android:paddingTop="10dip" >
<TextView

<TextView
android:id="#+id/phone"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
SearchResults.java
public class SearchResults {
private String name = "";
private String cityState = "";
private String phone = "";
public void setName(String name) {
this.name = name;
}

if (convertView == null) {

holder.txtPhone = (TextView) convertView.findViewById(R.id.phone);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.txtName.setText(searchArrayList.get(position).getName());
holder.txtCityState.setText(searchArrayList.get(position).getCityState());
holder.txtPhone.setText(searchArrayList.get(position).getPhone());
return convertView;
}
static class ViewHolder {
TextView txtName;
TextView txtCityState;
TextView txtPhone;
}
}
MainActivity.java
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ArrayList<SearchResults> searchResults = GetSearchResults();
final ListView lv = (ListView) findViewById(R.id.srListView);
lv.setAdapter(new MyCustomBaseAdapter(this, searchResults));
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
Object o = lv.getItemAtPosition(position);
SearchResults fullObject = (SearchResults)o;
Toast.makeText(MainActivity.this, "You have chosen: " + " " + fullObject.getName(), Toast.LENGTH_LONG).show();
}
});
}
private ArrayList<SearchResults> GetSearchResults(){
ArrayList<SearchResults> results = new ArrayList<SearchResults>();
SearchResults sr = new SearchResults();
sr.setName("Hospital de Lisboa");
sr.setCityState("Avenida 123 nº15");
sr.setPhone("212321234");
results.add(sr);
sr = new SearchResults();
sr.setName("Hospital de Santarém");
sr.setCityState("Rua de Cima nº20");
sr.setPhone("234234234");
results.add(sr);
return results;
}
}

You can't just create a new textview and create new methods to your SearchResults then just sr.setNewLine()?

error message describes "java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.TextView.setText(java.lang.CharSequence)' on a null object reference
at com.eos.parcelnoticemanager.tools.FloorAdapter.onBindViewHolder"

The GridViewHolder inside your FloorAdapter is pointing to the wrong XML Id tag for the TextView that's why it's throwing NullPointerException
Change this in your GridViewHolder
tvFloorNum = itemView.findViewById(R.id.tvRoomNumber);
to this
tvFloorNum = itemView.findViewById(R.id.tvFloorNumber);
Then it should work

Use SearchView with a ListView that have an image and text

I have a problem, I learnt how to use a SearchView with text, but I have an Activity where the listView have an image and text, but I couldnt find the way to display the filter.
So, I debug the code in order to understand why this happens and I get this in the LogCat:
java.lang.RuntimeException: Unable to start activity ComponentInfo{mundo.hola.app.frank.com.universidad2/mundo.hola.app.frank.com.universidad2.RankingActividad}: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.SearchView.setOnQueryTextListener(android.widget.SearchView$OnQueryTextListener)' on a null object reference
the code compiles great, but when I try to have access to this activity trough an Intent the App crashes.
If someone could help me i would be greatful.

Custom List view View Holder pattern with RadioGroup state not maintained

I have implemented CustomListView with RadioGroup. When I selected the radio button of first/beginning rows and scrolling to the end of list, last row elements are automatically selected. And when I'm scrolling back to beginning of List, Radiogroup state is not maintained. I have spent lot of time with this issue.
Kindly help me out where I'm doing a mistake.

Change the conditions in if statement as below and it will work.
if(list.get(position).getSelected() == viewHolder.firstRadio.getId())
{
viewHolder.firstRadio.setChecked(true);
viewHolder.secondRadio.setChecked(false);
}
else if(list.get(position).getSelected() == viewHolder.secondRadio.getId())
{
viewHolder.secondRadio.setChecked(true);
viewHolder.firstRadio.setChecked(false);
}
else
{
viewHolder.secondRadio.setChecked(false);
viewHolder.firstRadio.setChecked(false);
}

I'm not sure how it is working now. I've spent lot of days in this issue. Overriding getViewTypeCount and getItemViewType resolved my issue.
#Override
public int getViewTypeCount() {
if (objects.size() > 0) {
return objects.size();
}
return 1;
}

Gridview adapter images with title name for images group

I have a gridView witch contains a group of images with two columns, what I want to do is to put a title for a group of images.
Now I can do that but the problem that title is that the title is only in one column and the second column is always empty, how can I put the title in the two columns?
Here is my adapter:
public class MultimediaPhotosAdapter extends BaseAdapter {
private Context mContext;
private List<ImagesDto> imagesDto = new ArrayList<ImagesDto>();
ImagesFlickrDto imagesFlickrDto;
final String formatImage = ImagesNameFormat.FORMAT_IMAGE_DEFAULT.getImagesNameFormat();
ImagesFormatsDto currentImageFormatToDisplay;
GridView gridViewImages;
public MultimediaPhotosAdapter(Context context, GridView gridViewImages) {
this.gridViewImages = gridViewImages;
this.mContext = context;
}
#Override
public int getCount() {
return imagesDto.size();
}
#Override
public Object getItem(int position) {
return imagesDto.get(position);
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View itemView = null;
HolderElementGridView holderElementGridView;
ImagesDto currentImage = imagesDto.get(position);
if(convertView == null) {
holderElementGridView = new HolderElementGridView();
itemView = View.inflate(mContext,R.layout.item_multimedia_photo,null);
holderElementGridView.image = (NetworkImageView) itemView.findViewById(R.id.imageView);
holderElementGridView.title = (TextView) itemView.findViewById(R.id.title);
itemView.setTag(holderElementGridView);
}
else {
itemView = convertView;
holderElementGridView = (HolderElementGridView)itemView.getTag();
}
if(imagesDto.get(position).isFirstElementOfCategorie()){
holderElementGridView.image.setVisibility(View.GONE);
holderElementGridView.title.setVisibility(View.VISIBLE);
holderElementGridView.title.setText(currentImage.getTitle());
}
else if(imagesDto.get(position).getUrl()!=null){
holderElementGridView.image.setVisibility(View.VISIBLE);
holderElementGridView.title.setVisibility(View.GONE);
holderElementGridView.image.setImageUrl(StringFormat.getUrlImage(mContext, currentImage.getUrl(), currentImageFormatToDisplay.getSuffix(), currentImageFormatToDisplay.getExtension()),VolleySingleton.getInstance(mContext).getImageLoader());
holderElementGridView.image.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
DrawerLayoutInterface screenInterface=(DrawerLayoutInterface)mContext;
if(screenInterface!=null)
screenInterface.showDiaporama(imagesFlickrDto,position);
}
});
}
// column near title is empty
else{
holderElementGridView.image.setVisibility(View.VISIBLE);
holderElementGridView.title.setVisibility(View.GONE);
}
return itemView;
}
public void update(ImagesFlickrDto imagesFlickrDto){
this.imagesFlickrDto = imagesFlickrDto;
this.imagesDto = imagesFlickrDto.getListImages();
AdministrerImagesSA administrerImages = new AdministrerImagesSAImpl();
currentImageFormatToDisplay = administrerImages.getFormatByProriete(imagesFlickrDto.getImagesFormatsDto(), formatImage);
}
class HolderElementGridView{
NetworkImageView image;
TextView title;
}
}

Cant display listview in AlertDialog android

I want to display ArrayList of object in AlertDialog but my list view dont show. Here is my code.
public class PrzystanekDialog extends DialogFragment {
private ListView trasaPrzejazdu;
private ArrayList<Linia> trasaPrzejazduList;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the Builder class for convenient dialog construction
LayoutInflater inflater = getActivity().getLayoutInflater();
final View rootView = inflater.inflate(R.layout.dialog_layout, null);
//ustawienie lisview z wygenerowaną linia
trasaPrzejazduList = getArguments().getParcelableArrayList("linia");
trasaPrzejazdu = (ListView) rootView.findViewById(R.id.trasaListView);
final ArrayAdapter<Linia> adapter = new ArrayAdapter<Linia>(getActivity(),R.layout.listbox_dialog_element, trasaPrzejazduList);
trasaPrzejazdu.setAdapter(adapter);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
final ViewPager mViewPager;
mViewPager = (ViewPager) getActivity().findViewById(R.id.pager);
builder.setView(inflater.inflate(R.layout.dialog_layout, null));
//getActivity().setContentView(inflater.inflate(R.layout.dialog_layout, null));
builder.setMessage(R.string.choose)
.setPositiveButton(R.string.start_trip, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
mViewPager.setCurrentItem(1);
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Toast.makeText(getActivity().getApplicationContext(), "Anulowano podróż.", Toast.LENGTH_LONG).show();
}
});
return builder.create();
}
}
Here is my ArrayAdapter
public class DialogListAdapter extends BaseAdapter {
private List<Linia> listData;
private LayoutInflater layoutInflater;
public DialogListAdapter(Context context, List<Linia> listData) {
this.listData = listData;
layoutInflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
return listData.size();
}
#Override
public Linia getItem(int position) {
return listData.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.listbox_dialog_element, null);
holder = new ViewHolder();
holder.start = (TextView) convertView.findViewById(R.id.przystanekStartowy);
holder.end = (TextView) convertView.findViewById(R.id.przystanekDocelowy);
holder.vehicleImage = (ImageView) convertView.findViewById(R.id.line_image);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
//listData.get(position).getHeadline()
if(listData.get(position).getTypLini().toString() == "bus")
holder.vehicleImage.setImageResource(R.drawable.autobus_ico);
else
holder.vehicleImage.setImageResource(R.drawable.tram_ico);
holder.start.setText(listData.get(position).getStopPrzystanki().get(0).getNazwa_przystanku());
holder.end.setText(listData.get(position).getStopPrzystanki().get(listData.get(position).getStopPrzystanki().size()-1).getNazwa_przystanku());
return convertView;
}
static class ViewHolder {
ImageView vehicleImage;
TextView start;
TextView end;
}
}
And here is my xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/trasaListView"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
I have no compile errors. Thank you very much for help.
EDIT:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
