I am populating the listview with items from parse.com. It was working fine not long ago and then for some reason once i changed from eclipse to android studio it started only showing the latest item.
Adapter
public class MyCustomAdapter extends ParseQueryAdapter<ParseObject> {
public MyCustomAdapter(Context context) {
super(context, "Comments", R.layout.comments_listview_item);
}
#Override
public View getItemView(ParseObject comment, View view, ViewGroup parent) {
view = View.inflate(getApplicationContext(), R.layout.comments_listview_item, null);
mListViewReferences(view);
loadComments();
commenttext.setText(comment.getString("Comment"));
commentersUserName.setText(comment.getString("Commenter"));
return super.getItemView(comment, view, parent);
}
/**
* Set References
*/
private void mListViewReferences(final View view) {
commentersUserName = (TextView) view.findViewById(R.id.commentersUserName);
commenttext = (TextView) view.findViewById(R.id.commenttext);
}
}

void loadComments() {
runOnUiThread(new Runnable() {

you should return view

mListViewReferences(view);
//loadComments();
commenttext.setText(comment.getString("Comment"));

This error over here:
Cannot resolve method 'get' in 'TextView'
at
intent.putExtra("Name",String.valueOf((holder.Name_id).get(position)));
intent.putExtra("Type",String.valueOf((holder.Type_id).get(position)));
intent.putExtra("Location",String.valueOf((holder.Location_id).get(position)));
Tells the whole story, just replace it with:
intent.putExtra("Name",holder.Name_id.getText());
intent.putExtra("Type",holder.Type_id.getText());
intent.putExtra("Location",holder.Location_id.getText());
This way, you would get the text inside of them.
All you have to do is to write the correct method since #get() doesn't exist.
I have a view in an activity as below .I want to set Margin to the view.But i used Viewgroup.LayoutParams but it doesn't change the view of the row.Below i have given custom adapter which takes data from firstpagerowitems.xml.I have given the java code for adapter .I tried doing android:layout_marginbottom="10dp" for firstpagerowitems.xml and firstpage.xml but it doesnt work.
class MyAdapter extends ArrayAdapter<String> {

this.context = c;
this.rTitle = title;
this.rDescription = description;
this.rImgs = imgs;

I have a custom layout for the list's cells where you have a checkbox and 3 text elements. I found on Stackoverflow that I should add android:descendantFocusability = "blocksDescendants" on my LinearLayout where the list is but it doesn't change anything.
Here is my XML for the page with the list :
<?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:background="#color/colorPrimary"
android:clickable="true"
android:focusable="true"
android:orientation="vertical"
tools:context=".ui.home.AperoDetailFragment"
android:descendantFocusability="blocksDescendants">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:orientation="horizontal">
<TextView
android:id="#+id/name_apero"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingHorizontal="10dp"
android:gravity="left"
android:textSize="18sp" />
<TextView
android:id="#+id/date_apero"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingHorizontal="10dp"
android:ems="10"
android:gravity="right"
android:textSize="18sp" />
</LinearLayout>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#DDDDDD" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:orientation="horizontal">
<TextView
android:id="#+id/txtView_shopping_list"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="1"
android:paddingHorizontal="10dp"
android:text="#string/shopping_list_title" />
<Button
android:id="#+id/btn_add_ingredients"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

</LinearLayout>
<ListView
android:id="#+id/list_ingredient"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal" />
</LinearLayout>
then in my Java code I set the listener like this :
#Override
public View onCreateView(#NonNull final LayoutInflater inflater,
final ViewGroup container, Bundle savedInstanceState) {
root = inflater.inflate(R.layout.fragment_detail_apero, container, false);
final TextView name = (TextView) root.findViewById(R.id.name_apero);
name.setText(detailApero.name);
TextView date = (TextView) root.findViewById(R.id.date_apero);
date.setText(detailApero.date);
// some code that aren't useful right now
//-------------- List of ingredients for the detailed apero
final ListView list_ingredient = (ListView) root.findViewById(R.id.list_ingredient);
LaperoDatabase db = Room.databaseBuilder(root.getContext(),
LaperoDatabase.class, "lapero_db").allowMainThreadQueries().build();
IngredientDao dbIngredient = db.getIngredientDao();
//#TODO control if we get the right ingredients
ArrayList<Ingredient> ingredient_of_this_apero = (ArrayList<Ingredient>) dbIngredient.getIngredientsFromApero(detailApero.aid);
IngredientAdapter adapter = new IngredientAdapter(root.getContext(), R.layout.ingredient_cell_layout, ingredient_of_this_apero);
list_ingredient.setAdapter(adapter);
list_ingredient.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapter, View v, int position, long id) {
Ingredient selected_ingredient = (Ingredient) adapter.getItemAtPosition(position);
Log.e("test","okasodkdaso");
}
});
return root;
}
I also tried using a OnItemLongClickListener but it also does nothing. How can I put a listener for the list items ?
I am working on an Android project in which I am using TabLayout to show tabs as shown in the image below. As you can see in the screenshot, the tabs are all aligned on the left side. How can I add spaces properly so the three tabs fill out the entire width instead of getting clubbed in on left side. Thank you.

Thank you.
Please remove below line in your activity file
tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
and Change your tablayout

for (int a= 0; a< tabLayout.getTabCount(); a++) {
View tabView = LayoutInflater.from(context)
.inflate(LayoutInflater.from(this), R.layout.item_main_tabview, null, false);
tabView.setLayoutParams(new TableLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
tabView.setPadding(0, 0, 0, 0);
tabLayout.getTabAt(a).setCustomView(tabViewBinding.getRoot());
}
Thus You can add space between tabs in tablayout
I have created a custom adapter for my list (JobAdapter), however, whenever I set the adapter, even if there are values (jobs arraylist parameter has a size of 2), nothing is displayed on my activity.
This is my adapter:
public class JobAdapter extends ArrayAdapter<Job> {
private final Context context;
private final ArrayList<Job> jobs;
private final int layoutResourceId;
public JobAdapter(Context context, int layoutResourceId, ArrayList<Job> jobs) {
super(context, layoutResourceId, jobs);
this.context = context;
this.jobs = jobs;
this.layoutResourceId = layoutResourceId;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
ViewHolder holder = null;
LayoutInflater inflater = (LayoutInflater) context.getSystemService((Activity.LAYOUT_INFLATER_SERVICE));
if (view == null) {
view = inflater.inflate(layoutResourceId, parent, false);
holder = new ViewHolder();
holder.title = (TextView)view.findViewById(R.id.tv_jobTitle);
holder.payrate = (TextView)view.findViewById(R.id.tv_payRate);
holder.startdate = (TextView)view.findViewById(R.id.tv_startDate);
holder.workinghrs = (TextView)view.findViewById(R.id.tv_duration);
holder.location = (TextView)view.findViewById(R.id.tv_location);
holder.companyname = (TextView)view.findViewById(R.id.tv_companyName);
holder.description = (TextView)view.findViewById(R.id.tv_JobDesc);
holder.experience = (TextView)view.findViewById(R.id.tv_experienceReq);
holder.equipment = (TextView)view.findViewById(R.id.tv_equipmentReq);
view.setTag(holder);
} else {
holder = (ViewHolder)view.getTag();
}
Job j = jobs.get(0);
holder.title.setText(j.getJobTitle());
holder.payrate.setText(j.getPayrate());
holder.startdate.setText(j.getDurationStart());
holder.workinghrs.setText(j.getWorkingHrs());
holder.location.setText(j.getLocation());
holder.companyname.setText("ABC Company");
holder.description.setText(j.getDescription());
holder.experience.setText("3-5 years");
holder.equipment.setText("Hardhat");
//TODO: add hardhat, boots and other field to objects mapped
return view;
}
static class ViewHolder
{
TextView title;
TextView payrate;
TextView startdate;
TextView workinghrs;
TextView location;
TextView companyname;
TextView description;
TextView experience;
TextView equipment;
}
}
This is how I am setting the adapter in the AsyncTask OnPostExecute:
protected void onPostExecute(ArrayList<Job> result) {
arrayAdapter = new JobAdapter(getApplicationContext(), R.layout.jobcard, result);
arrayAdapter.notifyDataSetChanged();
flingContainer.setAdapter(arrayAdapter);
}
What could be the problem with this? There is no error message in Logcat and the application still runs fine, just no data shown. Data should be shown in the jobcard.xml layout which is defined for the JobAdapter.
Thanks in advance for any help with this!
EDIT:
It looks like getView() in the JobAdapter is not being called, I have tried to override the getCount() method in the JobAdapter to return 1 just so I can see one element but that did not work either.
