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);

Center ViewGroup views with Android-DraggableGridViewPager

I want to thanks zzhouj first of all, but I'm trying to use his Android-DraggableGridViewPager with some errors. this is his class:
Android-DraggableGridViewPager RAW
This is my layout:

I'm using it to create a simple gridview with draggable layout in, but if I reduce size of that ViewGroup, the element wont stay in center, because elements go on the left.
Do you have any ideas? Thanks in advance!

OnClickListener not working with fragments

I'm cant get the onclicklistener to work with fragments. I've searched stackoverflow and tried all the tips but i still cant get it to work. So i do my first post here. I've tried adding android:focusable="false", android:clickable="false" and android:descendantFocusability="blocksDescendants" to the layouts with no luck. Ive removed them because they make no difference. I've tried other solutions as well but none of them works. This is my first post so if i posted something wrong let me know and ill redo it, I've borrowed someones customlist just to get a working example.
Here is one of the fragments i want a clickable list in
public class ActivitiesFragment extends Fragment {
ListView list;
String[] maintitle ={
"Aktivitet 1","Aktivitet 2",
"Aktivitet 3","Aktivitet 4",
"Aktivitet 5",
};
String[] subtitle ={
"A","B",
"C","D",
"E",
};
Integer[] imgid={
R.drawable.ic_dashboard_black_24dp,R.drawable.ic_dashboard_black_24dp,
R.drawable.ic_dashboard_black_24dp,R.drawable.ic_dashboard_black_24dp,
R.drawable.ic_dashboard_black_24dp,
};
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_activities, container, false);
MyListAdapter adapter = new MyListAdapter(getActivity(), maintitle, subtitle,imgid);
list = (ListView) rootView.findViewById(R.id.list);
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if(position == 0) {
Toast.makeText(getActivity().getApplicationContext(),"One",Toast.LENGTH_SHORT).show();
}
else if(position == 1) {
Toast.makeText(getActivity().getApplicationContext(),"Two",Toast.LENGTH_SHORT).show();
}
else if(position == 2) {
Toast.makeText(getActivity().getApplicationContext(),"Three",Toast.LENGTH_SHORT).show();
}
else if(position == 3) {
Toast.makeText(getActivity().getApplicationContext(),"Four",Toast.LENGTH_SHORT).show();
}
else if(position == 4) {
Toast.makeText(getActivity().getApplicationContext(),"Five",Toast.LENGTH_SHORT).show();
}
}
});
return rootView;
}
}
Here is the Adapter:
public class MyListAdapter extends ArrayAdapter<String> {
private final Activity context;
private final String[] maintitle;
private final String[] subtitle;
private final Integer[] imgid;
public MyListAdapter(Activity context, String[] maintitle,String[] subtitle, Integer[] imgid) {
super(context, R.layout.mylist, maintitle);
// TODO Auto-generated constructor stub
this.context=context;
this.maintitle=maintitle;
this.subtitle=subtitle;
this.imgid=imgid;
}
public View getView(int position,View rowView,ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
rowView = inflater.inflate(R.layout.mylist, null,true);
TextView titleText = (TextView) rowView.findViewById(R.id.title);
ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
TextView subtitleText = (TextView) rowView.findViewById(R.id.subtitle);
titleText.setText(maintitle[position]);
imageView.setImageResource(imgid[position]);
subtitleText.setText(subtitle[position]);
return rowView;
}
}
The xml for the fragment:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="50dp"/>
</RelativeLayout>
The xml for the list:

android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">

list.add(new ItemData("Aktivitet 5","E",R.drawable.ic_dashboard_black_24dp))
RVAdapter adapter = new RVAdapter(this, list);
rvList.setLayoutManager(new LinearLayoutManager(getContext()));
rvList.setAdapter(adapter);
}
#Override
public void onItemClicked(ItemData data, int position) {
// item click will be listened here
Toast.makeText(getContext(), String.valueOf(position), Toast.LENGTH_SHORT).show();
}
}

}
});
}
#Override
public int getItemCount() {

}
interface ItemClickListener {

Update 1:
Add these lines to the root tag of item layout:
android:focusable="true"
android:clickable="true"
Like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusable="true"
android:clickable="true"
android:orientation="horizontal">
...
</LinearLayout>

Time ago I had a similar problem, with an ImageView in my list item. My solution was changing android:focusable to false inside the ImageView block. I never knew why, but it worked fine.
Anyway, I strongly recommend to start using RecyclerView and ViewHolder pattern. https://developer.android.com/guide/topics/ui/layout/recyclerview
It's much more powerful, flexible and a major enhancement over ListView.

Android ListView item clicked not working

I don't understand what's going wrong, when clicking an item on the list nothing appends.
my environment is minsdk:21, maxsdk:27, java 8 (openjdk), android-studio 3.1.4, terminal android 6.0
note : using FragmentManager or SupportFragmentManager provides the same result.

I am creating an object of MyAdapter and calling it by passing a List and Activity.this
when i try to toast the size of the list passed i get the proper size
however only the first item of the list gets displayed on the screen

GridView onClickListener/onItemClickListener not working

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.
My code is as below,
// Contact_Backup.java
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));
}
}
//Custom_Adapter
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);
} else {
grid = (View) convertView;
}
grid.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d("TAG::",""+position);

return grid;

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() {
#Override
public void onClick(View v) {
Log.d("TAG::",""+position);
}
});
}
return grid;
}
}
Hope this helps you out !
