Not being able to place an onClickListener on the Grid Items provided by a custom BaseAdapter

I currently have a grid view using a base adapter inside a fragment and I am trying to transfer to a different fragment when one of the items is clicked but none of the solutions I found on stack overflow has worked. I might miss something.
Adapter

public CategoriesAdapter(List<Category> apps, Context context) {
this.context = context;
this.categoryList = (ArrayList<Category>) apps;
}

if (view == null) {

view = inflater.inflate(R.layout.category_list_content, parent, false);
viewHolder = new ViewHolder();
viewHolder.textName = view.findViewById(R.id.textName);
viewHolder.imageView = view.findViewById(R.id.iconView);
view.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) view.getTag();
}
// here we are setting up the names and images
viewHolder.textName.setText(categoryList.get(position).getName());
viewHolder.imageView.setImageResource(this.context.getResources().getIdentifier(categoryList.get(position).getCategoryIconId(), "mipmap", this.context.getPackageName()));
return view;
}
}
Fragment's OnCreate

final GridView gridView = Objects.requireNonNull(getView()).findViewById(R.id.gridViewNewContract);
gridView.setAdapter(new CategoriesAdapter(response.body(), getActivity()));
}
#Override

toastShower.showToast("There has been a problem with retrieving the categories data!", getContext());
}
}

If you need any more information I will gladly provided.
I can mention that I've tried placing listeners both in the adapter and in the fragment directly on the grid.

please try this
viewHolder.imageView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//do stuff
}
});

How to select item in the list view programmatically

I have an ArrayList<String> List which contains some items from the listview all_list. How can I select these items in the list view all_list programmatically by checking the ArrayList<String> List contents?
for e.g., listview all_list contains [0] apple
[1] orange
[2] banana
In ArrayList<String> List, I have orange so I want item on position 1 on the listview all_list to be selected (highlighted) automatically.
I have tried using all_list.setItemChecked(), but it does nothing and shuts down the application. I am performing the operation after listing the adapter.

set an onItemClickListener to the listview such that on click, you set a boolean flag that sets the checkbox in each row to selected. then call notifyDataSetChanged()

Try this
MainActivity.java
package com.example.multiseekbar;
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
public class MainActivity extends Activity {
ListView listView1;
ArrayList<ModelClass> modelClass = new ArrayList<ModelClass>();
FruitSelectAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
modelClass.add(new ModelClass("Orange", true));
modelClass.add(new ModelClass("Apple", false));
modelClass.add(new ModelClass("Banana", false));
modelClass.add(new ModelClass("Grapes", false));
listView1 = (ListView) findViewById(R.id.listView1);
adapter = new FruitSelectAdapter(MainActivity.this, modelClass);
listView1.setAdapter(adapter);
listView1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
if(modelClass.get(arg2).isSelected()){
modelClass.get(arg2).setSelected(false);
}else{
modelClass.get(arg2).setSelected(true);
}
adapter.notifyDataSetChanged();
}
});
}
}

Only expandable listview showing up in activity

I'm making an android app for an automatic salad machine. The app lets you choose your ingredients and such, and then sends it to the machine. I set up an activity with an expandable listview to hold the ingredients, but I also need a next button on the activity and a nutritional information box below it. I added them to the activity, but when I run it only the expandable listview shows up.
Here's the code for the activity:
<?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="vertical"
android:weightSum="1">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"
android:id="#+id/button"
android:layout_gravity="right" />
<ExpandableListView
android:id="#+id/list"
android:layout_height="286dp"
android:layout_width="match_parent"
android:groupIndicator="#null"
android:divider="#A4C739"
android:dividerHeight="0.5dp"
android:layout_weight="1.15" />
<TextView
android:layout_width="match_parent"
android:layout_height="77dp"
android:text="Nutrition Facts:"
android:id="#+id/nutritionTV" />
</LinearLayout>
and here's the code for the class that goes with it:
package com.picknchew.companionapp;
import java.util.ArrayList;
import android.app.ExpandableListActivity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.widget.ExpandableListView;
public class ChooseIngredientsActivity extends ExpandableListActivity{
private ArrayList<String> parentItems = new ArrayList<String>();
private ArrayList<Object> childItems = new ArrayList<Object>();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// this is not really necessary as ExpandableListActivity contains an ExpandableList
//setContentView(R.layout.main);
ExpandableListView expandableList = getExpandableListView(); // you can use (ExpandableListView) findViewById(R.id.list)
expandableList.setDividerHeight(2);
expandableList.setGroupIndicator(null);
expandableList.setClickable(true);
setGroupParents();
setChildData();
MyExpandableAdapter adapter = new MyExpandableAdapter(parentItems, childItems);
adapter.setInflater((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE), this);
expandableList.setAdapter(adapter);
expandableList.setOnChildClickListener(this);
}
public void setGroupParents() {
parentItems.add("Lettuce");
parentItems.add("Protein");
parentItems.add("Fruit");
parentItems.add("Dressings");
}
public void setChildData() {
// Android
ArrayList<String> child = new ArrayList<String>();
child.add("Romain");
child.add("Iceberg");
child.add("Arugula");
child.add("Green");
childItems.add(child);
// Core Java
child = new ArrayList<String>();
child.add("Tofu");
child.add("Shredded Cheddar");
child.add("Sliced Eggs");
child.add("Beans");
child.add("Avocado");
childItems.add(child);
// Desktop Java
child = new ArrayList<String>();
child.add("Melon");
child.add("Watermelon");
child.add("Pineapple");
child.add("Grapefruit");
childItems.add(child);
// Enterprise Java
child = new ArrayList<String>();
child.add("Honey Mustard");
child.add("Ranch");
child.add("Caesar");
child.add("Vinaigrette");
childItems.add(child);
}
}
and finally here's the code for the expandable list view adapter, in case that's relevant:
package com.picknchew.companionapp;
import java.util.ArrayList;
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;

import android.widget.Toast;
public class MyExpandableAdapter extends BaseExpandableListAdapter {
private Activity activity;
private ArrayList<Object> childtems;
private LayoutInflater inflater;
private ArrayList<String> parentItems, child;
public MyExpandableAdapter(ArrayList<String> parents, ArrayList<Object> childern) {
this.parentItems = parents;
this.childtems = childern;
}
public void setInflater(LayoutInflater inflater, Activity activity) {
this.inflater = inflater;
this.activity = activity;
}
#Override
public View getChildView(int groupPosition, final int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
child = (ArrayList<String>) childtems.get(groupPosition);
CheckBox checkbox = null;
if (convertView == null) {
convertView = inflater.inflate(R.layout.group, null);
}
checkbox = (CheckBox) convertView.findViewById(R.id.checkBox2);
checkbox.setText(child.get(childPosition));
convertView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {

}
});
return convertView;
}
#Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = inflater.inflate(R.layout.child, null);
}
((CheckedTextView) convertView).setText(parentItems.get(groupPosition));
((CheckedTextView) convertView).setChecked(isExpanded);
return convertView;
}
#Override
public Object getChild(int groupPosition, int childPosition) {
return null;
}
#Override
public long getChildId(int groupPosition, int childPosition) {
return 0;
}
#Override
public int getChildrenCount(int groupPosition) {
return ((ArrayList<String>) childtems.get(groupPosition)).size();
}
#Override
public Object getGroup(int groupPosition) {
return null;
}
#Override
public int getGroupCount() {
return parentItems.size();
}
#Override
public void onGroupCollapsed(int groupPosition) {
super.onGroupCollapsed(groupPosition);
}
#Override
public void onGroupExpanded(int groupPosition) {
super.onGroupExpanded(groupPosition);
}
#Override
public long getGroupId(int groupPosition) {
return 0;
}
#Override
public boolean hasStableIds() {
return false;
}
#Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return false;
}
}

Mixing fixed heights with weights won't work.
What you can do: set all elements' height to 0 and assign them weights.
What I would do: use a RelativeLayout, put the Button at the top, the TextView at the bottom (alignParentBottom="true") and the ListView inbetween like
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"
android:id="#+id/button" />
<TextView
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="77dp"
android:text="Nutrition Facts:"
android:id="#+id/nutritionTV" />
<ExpandableListView
android:layout_above="#+id/nutritionTV"
android:layout_below="#+id/button"
android:id="#+id/list"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:groupIndicator="#null"
android:divider="#A4C739"
android:dividerHeight="0.5dp" />
</RelativeLayout>
Result:
EDIT: You have to actually use this layout, which you at the moment don't do:
// this is not really necessary as ExpandableListActivity contains an ExpandableList
//setContentView(R.layout.main);
Uncomment the setContentView line. Don't forget to assign the views correctly, ie
ExpandableListView expandableList = getExpandableListView(); // you can use (ExpandableListView) findViewById(R.id.list)
will become
ExpandableListView expandableList = (ExpandableListView) findViewById(R.id.list)

How to get values from grid view

I have a gridview with editTexts as the individual views in it. I want to save the values that are in each of the editTexts because they are dissapearing when I switch to another fragment or press the home button, so how do I do that?
Would I need an array or arraylist that holds all of the views? How would I get the views if I did that?

but now it crashes when I press the home button and i get a stack overflow error

I'm not shure if this is the absolute and eligant solution, but you can try to add to your adapter a value container (like a dataset) for all the TextView's (it could be an ordinary ArrayList or somthing similar).
Then set a TextWatcher on every EditText:
mEditText.addTextChangedListener(new TextWatcher() {...});
And change the value of the list item every time the EditText value is changed.
In you onSaveInstanceState() method all you need is to retrive the value from the adapter.
The rest I think is simple.
Edit (Just to be clear)
Your adapter should luck somthing similar:
public class MyAdapter extends BaseAdapter {
// All the fancy stuff
List<String> dataset;
#Override
public View getView(...) {
//... othe code
mEditText.addTextChangedListener(new MyTextWatcher(position));
}
private class MyTextWatcher implements TextWatcher {
int index;
public MyTextWatcher(int index) {
this.index = index;
}
#Override
public void afterTextChanged(Editable s) {
dataset.set(index, s.toString());
}
}
}

In addition to TextWatchers, you could simply add all your Editexts to an array, and then when you need your text from them, you could simply cycle through the array and call getText().toString(); on all of them.
public class ImageAdapter extends BaseAdapter{
Context context;
EditText[] etCollection = new EditText[getCount()];
public ImageAdapter(Context context)
{
this.context = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View myView = convertView;
//LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if(convertView == null)
{
LayoutInflater li = infl;
myView= li.inflate(R.layout.grid_items, null);
}
EditText editText = (EditText) myView.findViewById(R.id.grid_item_edit_text_red);
//^ moved to outside the null block
etCollection[position] = editText;
return myView;
}

GridView and ImageButton Weird issue

public class SavedConferencesGridAdapter extends ArrayAdapter<String>{
Context mContext;
List<String> confernceList;
public SavedConferencesGridAdapter(Context context, int textViewResourceId, List<String> confernceList)
{
super(context,textViewResourceId,confernceList);
this.confernceList = confernceList;
this.mContext = context;
Log.e("TAG", confernceList.size()+"");
}
int[] picIds = new int[] { R.drawable.newschedule,R.drawable.newexhibitors,
R.drawable.newsponsers, R.drawable.newlocation,
R.drawable.newfavourites, R.drawable.newreminder,R.drawable.info,R.drawable.info,R.drawable.info,R.drawable.info,R.drawable.info,R.drawable.info };
#Override
public int getCount() {
// TODO Auto-generated method stub
return confernceList.size();
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View v;
if(convertView==null){
LayoutInflater li = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = li.inflate(R.layout.entity, null);
TextView tv = (TextView)v.findViewById(R.id.SpeakerName);
tv.setText("tt");
/*ImageView iv = (ImageView) v.findViewById(R.id.profilePic);
iv.setImageResource(picIds[position]);*/
}
else
{
v = convertView;
}
return v;
}
}
and here is my activity
public class SavedConferencesActivity extends Activity{
GridView confereneceGridView;
ArrayAdapter<String> conferneceAdapter;
Button btnUpdate;
List<String> conferenceList;
TextView txtHeading;
Boolean result = false;
#Override

super.onCreate(savedInstanceState);
}
protected void onStart() {
super.onStart();
setContentView(R.layout.homegridlayout);
initialize();
confereneceGridView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(SavedConferencesActivity.this, conferenceList.get(position)+"", Toast.LENGTH_SHORT).show();
}
#Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
conferneceAdapter = new SavedConferencesGridAdapter(this, android.R.layout.simple_list_item_1, conferenceList);
confereneceGridView.setAdapter(conferneceAdapter);
}
private void initialize() {
confereneceGridView = (GridView) findViewById(R.id.gridOfConference);
btnUpdate = (Button) findViewById(R.id.btnUpdate);
txtHeading = (TextView) findViewById(R.id.txtTag);
conferenceList = new ArrayList<String>();
conferenceList.add("AA");
conferenceList.add("BB");
conferenceList.add("CC");
if (conferenceList.size() == 0)
txtHeading.setText("No conferences saved");
else
txtHeading.setText("Selected Conferences");
}
}
Please help me in solving this problem. Or if any alternative available..

Simple. Provide this attribute for the ImageButton ,
android:focusable="false"
This problem usually occurs when there is a focussable element in the Grid.(Eg:Buttons, ImageButton etc).

Reason of this ImageButton is by Default is clickable and focusable, so Focus and click event never goes to ItemView.
Set Properties
android:focusable-"false"
and
android:clickable="false"

Your item's Layout should be:
<LinearLayout ...
android:descendantFocusability="blocksDescendants">
<ImageButton ...
android:focusable="false"
android:focusableInTouchMode="false"/>
</LinearLayout>
Don't forget setOnClickListener for ImageButton in Adapter.

in your adapter class,
before you return the view "v", add the "onClickListener" to "v"
v.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, position, Toast.LENGTH_SHORT).show();
}
});
