I have used Fragment in my code. i have to display custom ListView in fragment. But I would like to handle Button's onClickListener event which is in this ListView.How to use these Button components in Fragment class? Because ListView's row layout is another layout I can use it in the Fragment class.Here is my code:
My fragmnent class
public class VoteFragment extends Fragment
{
ListView list_model;
View rootView;
private String models_name[]={"MehararPaurKamali", "Elmira Panajavi","Hanay YavariMoghadam","MehararPaurKamali"};
private String models_adress[]={"Icon Girmfriend", "Deccan","ShivajiNagar","India"};
int model_images[]={R.drawable.karina,R.drawable.karina,R.drawable.karina,R.drawable.karina};
ArrayList<ModelListItem> modelList;
ModelListItem modelItem;
Button btn_home_model_plus;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
modelList=new ArrayList<ModelListItem>();
for(int i=0;i<models_name.length;i++)
{ modelItem=new ModelListItem();
modelItem.setModelname(models_name[i]);
modelItem.setModelAdress(models_adress[i]);
modelItem.setModel_image(model_images[i]);
modelList.add(modelItem);
}
rootView = inflater.inflate(R.layout.frag_vote,container, false);
setUI();
//Public void myClickHandler(){}
return rootView;
}
private void setUI()
{
list_model=(ListView)rootView.findViewById(R.id.list_home_model);
btn_home_model_plus=(Button)getView().findViewById(R.id.btn_home_model_plus);
}
}
Adapter class is
public class HomeModelListAdapter extends BaseAdapter implements OnClickListener
{
private ArrayList<ModelListItem> modelList;
private Context context;
Button btn_home_model_plus,btn_home_model_vote;
FragmentManager fragmentmanager;
public HomeModelListAdapter(Context context, ArrayList<ModelListItem> modelList)
{
this.context=context;
this.modelList=modelList;
}
#Override
public int getCount()
{
return modelList.size();
}
#Override
public Object getItem(int arg0)
{
return modelList.get(arg0);
}
#Override
public long getItemId(int arg0)
{
return arg0;
}
/*private view holder class*/
private class ViewHolder
{
ImageView imgModelimage;
TextView txtModeName;
TextView txtModelAdress;
}
#Override
public View getView(int position, View convertView, ViewGroup arg2)
{ ViewHolder holder = null;
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
{
convertView = mInflater.inflate(R.layout.fram_home_list, null);
holder = new ViewHolder();
holder.txtModeName= (TextView) convertView.findViewById(R.id.txt_home_model_name);
holder.txtModelAdress = (TextView) convertView.findViewById(R.id.txt_home_model_adress);
holder.imgModelimage = (ImageView) convertView.findViewById(R.id.img_home_model);
convertView.setTag(holder);
}
holder = (ViewHolder) convertView.getTag();
holder.txtModeName.setText(modelList.get(position).getModelname());
holder.txtModelAdress.setText(modelList.get(position).getModelAdress());
holder.imgModelimage.setImageResource(modelList.get(position).getModel_image());
btn_home_model_plus=(Button)convertView.findViewById(R.id.btn_home_model_plus);
btn_home_model_vote=(Button)convertView.findViewById(R.id.btn_home_model_vote);
btn_home_model_plus.setOnClickListener(this);
return convertView;
}
#Override
public void onClick(View v)
{ Fragment fragment = null;
switch (v.getId())
{
case R.id.btn_home_model_plus:
System.out.println("Hi.................");
fragment = new ModelProfileDetailFragment();
break;
case R.id.btn_home_model_vote:
break;
default:
break;
}
if (fragment != null)
{
fragmentmanager.beginTransaction().add(R.id.fram_home, fragment).commit();
//notifyDataSetChanged();
}
}

Please give me suggestion.
All right I think your problem is quite simple. All you need to do is edit your HomeModelListAdapter's getView() method class like this.
public class HomeModelListAdapter extends BaseAdapter {
.....
.....
#Override
public View getView(int position, View convertView, ViewGroup arg2)
{
.....
btn_home_model_plus.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//do your stuff here
}
});
btn_home_model_vote.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//do your stuff here
}
});
....
}
....
}
Hopefully this should solve your problem.
Try this to access your fragment manager
((Activity) context).getFragmentManager();
I want to know how your list view is linked with your fragment.

I have a problem with spinner it do not let me select one item. I tried a lot of things and that still not working.
The picture shows that the spinner is in blank when the activity load
When I clicked the arrow it shows the items
but when I choose one, nothing happends.

This is the Layout of the activity.

That is the custom layout for the spinner
Public class ComboAdapter extends BaseAdapter{
private List<Combo> combos;
private Activity activity;
private LayoutInflater inflater;
public ComboAdapter(List<Combo> combos, Activity activity) {
this.combos = combos;
this.inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return combos.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (convertView == null){
view = inflater.inflate(R.layout.combo_list_item, null);
TextView tvId = (TextView) view.findViewById(R.id.tvNumeroOpcion);
TextView tvDescripcion = (TextView) view.findViewById(R.id.tvDescriptionOption);
tvId.setText(combos.get(position).getId());
tvDescripcion.setText(combos.get(position).getDescripcion());
}
return view;
}
#Override
public View getDropDownView(int position, View convertView,
ViewGroup parent) {
return getView(position, convertView,parent);
}
}
That is my Adapter
And below is my activity.
public class DatosGeneralesActivity extends AppCompatActivity {
private TextView tvSubestacionDato;
private List<Combo> listaCombo;
private Spinner spinnerSubestacion;
private ArrayAdapter<Combo> adapterSubestacion;
String seleccion;
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_datos_generales);
//Inicializando textos
tvSubestacionDato = (TextView) findViewById(R.id.tvSubestacionDato);
//Inicializanco listas
listaCombo = new ArrayList<>();
//Inivializando spinners
spinnerSubestacion = (Spinner) findViewById(R.id.spinnerSubEstacion);
AppService service = API.getCombos().create(AppService.class);
Call<List<Combo>> subestacionCall = service.getSubestacion();
subestacionCall.enqueue(new Callback<List<Combo>>() {
#Override
public void onResponse(Call<List<Combo>> call, Response<List<Combo>> response) {
listaCombo.clear();
listaCombo.addAll(response.body());
}
#Override
public void onFailure(Call<List<Combo>> call, Throwable t) {
}
});
//final ComboAdapter adapter = new ComboAdapter(listaCombo, DatosGeneralesActivity.this);
final ArrayAdapter<Combo> adapter = new ArrayAdapter<Combo>(this, R.layout.support_simple_spinner_dropdown_item, listaCombo);
spinnerSubestacion.setAdapter(adapter);
spinnerSubestacion.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
adapter.notifyDataSetChanged();
Toast.makeText(DatosGeneralesActivity.this, ""+position, Toast.LENGTH_SHORT).show();
tvSubestacionDato.setText(listaCombo.get(position).getDescripcion());
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
}
Try this changes:
Call adapter like:
ComboAdapter adapter = new ComboAdapter(DatosGeneralesActivity.this,
R.layout.combo_list_item, R.id.tvDescriptionOption, listaCombo);
now in adapter class:
public ComboAdapter(Activity context,int resouceId, int textviewId, List<Combo> list){
super(context,resouceId,textviewId, list);
this.combos = list;
this.inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
Also inside your getView() method inflate layout like:
if (convertView == null){
view = inflater.inflate(R.layout.combo_list_item, parent , false);
I am trying to implement a Card view inside grid view. The grid view is showing perfectly; even when I touch on a grid view item it's showing nothing. But when I click on the text which is display below its work. I referred This but not working...
Thanks.

use this method for clicking on a gridview item:
gridview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// your action when gridView item is clicked
}
});
Set the listener on the actual gridview object.
gridView.setOnItemClickListener(new OnItemClickListener()...);
Try this,
public class Contact_Backup extends AppCompatActivity {
#Bind(R.id.gridview)
GridView gridview;
String[] contact_screen_array;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.contact_backup);
ButterKnife.bind(this);
contact_screen_array = getResources().getStringArray(R.array.TextScreen);
String[] contact_icon_array = getResources().getStringArray(R.array.IconScreen);
String concat = "\nContacts";
gridview.setAdapter(new Custom_Adapter(getApplicationContext(),contact_icon_array,contact_screen_array,concat));
gridview.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
for(int i=0;i<contact_screen_array.length;i++) {
Log.d("TAG::", "Position"+contact_screen_array[i]);
}
}
});
}
}
Finally, I succeed. here is the code.
Just use Textview instead of Button in // new_app_card_layout.xml.
Just Update it,
<TextView
android:textSize="35.0sp"
android:textColor="#color/newclr"
android:layout_gravity="center"
android:id="#+id/Screen_icon"
android:background="#null"
android:padding="20sp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/fa_icon_contact"
android:drawablePadding="5.0dip"
android:textAllCaps="false"
android:textAlignment="center" />
Thank You so much, All of you for help... :)
Try this i have updated your custom Adapter class.please check again with this updated code.
public class Custom_Adapter extends BaseAdapter {
Context contaxt;
String[] Array_text;
String[] Array_icon;
String concat;
LayoutInflater inflater;
public Custom_Adapter(Context context,String[] Array_icon, String[] Array_text, String concat)
{
this.contaxt = context;
this.Array_text = Array_text;
this.Array_icon = Array_icon;
this.concat=concat;
inflater = (LayoutInflater)context.
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return Array_text.length;
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Bind(R.id.Screen_icon)
Button Screen_icon;
#Bind(R.id.Screen_text)
TextView Screen_text;
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View grid;
LayoutInflater inflater = (LayoutInflater) contaxt
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
grid = new View(contaxt);
grid = inflater.inflate(R.layout.new_app_card_layout, null);
ButterKnife.bind(this, grid);
Screen_text.setText(Array_text[position]+concat);
Screen_icon.setText(Array_icon[position]);
Typeface font = Typeface.createFromAsset(contaxt.getAssets(), "fonts/fontawesome-webfont.ttf" );
Screen_icon.setTypeface(font);
grid.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d("TAG::",""+position);
}
});
} else {
grid = (View) convertView;
grid.setOnClickListener(new View.OnClickListener() {

}
return grid;

}
Hope this helps you out !
I know here we have a lot of questions like mine, but I don't know why none works for me.
My objective: I have an AlertDialog with a ListView with a check box in each row, I can select some of the items, and I wish to make an ArrayList with the elements selected.
For that reason, I'm calling the SetOnclickListener, I put a Log inside the method, but does nothing.
I tried with focusable and clickable almost everywhere, but my Log doesn't appear.
Here My alert Dialog
private void callAdditionalDialog() {
LayoutInflater layoutInflater = LayoutInflater.from(ConfigProductActivity.this);
final View additionalView = layoutInflater.inflate(R.layout.dialog_additional, null);
additionalView.setFocusable(true);
// set the custom dialog components - text, buttons, accountants
TextView titleDialog = (TextView) additionalView.findViewById(R.id.title_additional);
titleDialog.setTypeface(boldFont);
Button buttonAccept = (Button) additionalView.findViewById(R.id.button_accept);
buttonAccept.setTypeface(boldFont);
Button buttonCancel = (Button) additionalView.findViewById(R.id.button_cancel);
buttonCancel.setTypeface(boldFont);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(ConfigProductActivity.this);
alertDialogBuilder.setView(additionalView);
final AlertDialog alertD = alertDialogBuilder.create();
alertD.setCanceledOnTouchOutside(false);
//Fill object of additional
final ListView additionalListView = (ListView) additionalView.findViewById(R.id.list_additional);
TextView additionalNotFound = (TextView) additionalView.findViewById(R.id.additional_not_found);
if (!withoutModifiers){
additionalAdapter = new AdditionalAdapter(ConfigProductActivity.this, additionalList);
additionalListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
additionalListView.setAdapter(additionalAdapter);
final ArrayList<ModifierEntity> modifierList = new ArrayList<ModifierEntity>();
additionalListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent,
View view, int position, long id) {
Object modifier = additionalListView.getAdapter().getItem(position).toString();
Log.d(TAG, "SOMETHIIIIING");
}
});
}
else{
additionalListView.setVisibility(View.GONE);
additionalNotFound.setVisibility(View.VISIBLE);
additionalNotFound.setTypeface(font);
buttonCancel.setVisibility(View.GONE);
}
//End of fill object of additional
buttonCancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
additionalBox.setEnabled(true);
alertD.dismiss();
}
});
buttonAccept.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//additional.setText(additionalAdapter.getCount());
additionalBox.setEnabled(true);
alertD.dismiss();
}
});
alertD.show();
}
Here my adapter:
public class AdditionalAdapter extends ArrayAdapter {
private static String TAG = AdditionalAdapter.class.getName();
private List<ModifierEntity> originalData = null;
private ConfigProductActivity activity;
private Typeface font;
private Typeface boldFont;
private static ModifierEntity modifier;
public AdditionalAdapter (ConfigProductActivity activity, List<ModifierEntity> listArray){
super(activity, R.layout.additional_item);
this.activity = activity;
this.originalData = listArray ;
font = Typeface.createFromAsset(activity.getAssets(),"HelveticaNeueThn.ttf");
boldFont = Typeface.createFromAsset(activity.getAssets(), "avgardm.ttf");
}
public static class Row
{
public TextView labelName;
public TextView labelPrice;
public CheckBox check;

Using interfaces I can solve my problem, this link provided me the solution, and bassically consist in create an interface and implement in my activity.
Like this:
1.- Interface
public interface MyListener {
void folderClicked();
}
2.- Implements the interface in the activity
public class ActivityA extends Activity implements MyListener
3.- You will have to auto override the method folderClicked it will look like this:
#Override
protected void folderClicked() {
// Do your stuff here.
}
4.- Send the activity listener to the adapter with constructor like this:
MyAdpater adapter = new MyAdpater(ActivityA.this);
5.- Your adapter class your code should be like this:
public class TimeLineAdapter extends BaseAdapter {
private MyListener mListener;
public TimeLineAdapter(MyListener listener) {
super();
mListener = listener;
}
holder.iconImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mListener.onFolderClicked()
//code to do stuff when the image is clicked
}
I am Trying to insert GridView in fragment. I have developed custom adapter to populate the gridview. Now everything is working fine but the gridview is not displaying in the fragment. I have check the getCount() method it is returning total length. So that means data is there but it is not displaying. I am pretty new with gridview so have no idea why it is happening. I tried the following answer but they didn't help me either.
Android: getView in adapter never called
Custom Adapter getView() method is not called
Gridview not displaying in fragment
Here is my code:
Tile Fragment Class:
public class TileFragment extends Fragment
{
public TileFragment(){
}
GridView gv;
Context context;
public static String [] prgmNameList={"Let Us C","c++","JAVA","Jsp","Microsoft .Net","Android","PHP","Jquery","JavaScript"};
public static int [] prgmImages={R.mipmap.dicover_disable,R.mipmap.discover_active, R.mipmap.home_disable,
R.mipmap.home_active,R.mipmap.lists_disable,R.mipmap.lists_active,
R.mipmap.profile_disable,R.mipmap.profile_active,R.mipmap.ic_search };
#Override

{

}
#Override

{
#SuppressLint("InflateParams")
// View v = LayoutInflater.from(getActivity()).inflate(R.layout.tile_fragment, null);
View v = inflater.inflate(R.layout.tile_fragment, container, false);
gv = (GridView) v.findViewById(R.id.gridView1);
gv.setAdapter(new CustomAdapter(getActivity(), prgmNameList,prgmImages));
return v;
}
#Override
public void onActivityCreated(Bundle savedInstanceState)
{
super.onActivityCreated(savedInstanceState);
}
}
Custom Adapter:
public class CustomAdapter extends BaseAdapter {
String [] result;

int [] imageId;
private static LayoutInflater inflater=null;
public CustomAdapter(FragmentActivity tileFragment, String[] prgmNameList, int[] prgmImages) {
result=prgmNameList;
imageId=prgmImages;
context = tileFragment;
inflater = ( LayoutInflater )context.
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override

return imageId.length;
}
#Override

return position;
}
#Override
public long getItemId(int position) {
return position;
}
public class Holder
{
TextView tv;
ImageView img;
}
#SuppressLint("ViewHolder")
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
Holder holder=new Holder();
View rowView;
rowView = inflater.inflate(R.layout.programlist, null);
holder.tv=(TextView) rowView.findViewById(R.id.textView1);
holder.img=(ImageView) rowView.findViewById(R.id.imageView1);
holder.tv.setText(result[position]);
holder.img.setImageResource(imageId[position]);
rowView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, "You Clicked " + result[position], Toast.LENGTH_LONG).show();
}
});
return rowView;
}
}

This is how I am adding the fragment:
HomeFragment:
public class HomeFragment extends Fragment
{
public HomeFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
FragmentTabHost mTabHost = new FragmentTabHost(getActivity());
mTabHost.setup(getActivity(), getChildFragmentManager());
Bundle b = new Bundle();
b.putString("key", "Tile");
mTabHost.addTab(mTabHost.newTabSpec("tile").setIndicator("Tile"), TileFragment.class, b);
//
b = new Bundle();
b.putString("key", "Map");
mTabHost.addTab(mTabHost.newTabSpec("map").setIndicator("Map"), ProfileFragment.class, b);
return mTabHost;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
//
}
Any Help will be appreciated ...
Try this:
mTabHost.setup(getActivity(), getChildFragmentManager(), R.layout.my_parent_fragment);
where R.layout.my_parent_fragment is your layout fragment where you have the tabhost.
Once you have verified that the GridView is displayed correctly in an Activity, we could deduce that this is not a problem with the Gridview neither the Adapter, the problem come from your FragmentTabHost definition or setup. You are returning your tabHost from your onCreateView(), for that you must set your layout or container in your tabHost, if you don't do this, how the fragment know where find your layout?
For more info, api here
Can't figure out the root of the problem but try this:
View rowView = convertView;
if(rowView != null) {
rowView = inflater.inflate(R.layout.programlist, null);
}
Try using this layout.
