Custom List adapter in Fragment

Custom List adapter in Fragment - android

I am currently trying to implement a custom listView for my Fragment, but when i try to add the item to the ListView it doesn't show up, and i get no exception or anything.
What i'm trying to do is to create an object with a name and a number by typing, both of these things work, but it seems like i did a mistake with the listView
Here is the Fragment with the ListView
package com.example.myapplicationteeeeeeeeeest.ui.BShoppingRecipe;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import com.example.myapplicationteeeeeeeeeest.R;
import java.util.ArrayList;
import java.util.List;
public class ShoppingListTab extends ShoppingRecipe {
private EditText inputIngredient;
private EditText inputQuantity;
private Button addButton;
private ListView listView;
private ShoppingListAdapter adapterListView;
private ArrayList<ShoppingList> ShoppingList;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate( R.layout.tab_fragment_one, container,false );
listView = (ListView) view.findViewById( R.id.shoppingList_listView );
addButton = (Button) view.findViewById( R.id.shoppingTab_button);
inputQuantity = (EditText) view.findViewById( R.id.quantity_editText );
inputIngredient = (EditText) view.findViewById( R.id.ingredient_editText );
ShoppingList = new ArrayList<>();
adapterListView = new ShoppingListAdapter( getActivity(),ShoppingList );
listView.setAdapter( adapterListView );
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
ShoppingList.remove(position);
adapterListView.notifyDataSetChanged();
return true;
}
});
addButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String ingredient = inputIngredient.getText().toString().trim();
String quantitiy = inputQuantity.getText().toString().trim();
if (!ingredient.isEmpty() && !quantitiy.isEmpty()) {
ShoppingList ShoppingListItem = new ShoppingList(ingredient, quantitiy);
ShoppingList.add(ShoppingListItem);
adapterListView.notifyDataSetChanged();
inputIngredient.setText("");
inputQuantity.setText("");
}
}
});
return view;
}
}
The Fragment Layout

The Costume ListAdapter
package com.example.myapplicationteeeeeeeeeest.ui.BShoppingRecipe;
import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
import com.example.myapplicationteeeeeeeeeest.R;
import java.util.ArrayList;
public class ShoppingListAdapter extends ArrayAdapter<ShoppingList> {
private ArrayList<ShoppingList> shoppingList;
private Context context;
public ShoppingListAdapter(Context context, ArrayList<ShoppingList> taskList) {
super(context, R.layout.shopping_list_item);
this.shoppingList = taskList;
this.context = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if(v == null){
LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = layoutInflater.inflate(R.layout.shopping_list_item, null);
}
ShoppingList taskItem = shoppingList.get(position);
if(taskItem != null){
TextView taskItemText = v.findViewById(R.id.shoppingList_Ingredient);
TextView taskItemDate = v.findViewById(R.id.shoppingList_Quantity);
taskItemText.setText(taskItem.getTask());
taskItemDate.setText(taskItem.getNumber());
}
return v;
}
}
And the Layout for the Item
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
>
<TextView
android:text="TextView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="#+id/shoppingList_Ingredient"
app:layout_constraintStart_toStartOf="parent"
android:layout_marginLeft="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintEnd_toStartOf="#+id/shoppingList_Quantity"
android:layout_marginEnd="8dp"
android:layout_marginRight="8dp"/>
<TextView
android:text="TextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/shoppingList_Quantity"
app:layout_constraintEnd_toEndOf="parent"
android:layout_marginEnd="8dp"
android:layout_marginRight="8dp"
android:layout_marginTop="8dp"
app:layout_constraintTop_toTopOf="parent"/>
</android.support.constraint.ConstraintLayout>

Try adding this method in your adapter class:
#Override
public int getCount() {
return shoppingList.size();
}
And also try not to use same name for your list variable and model class.
Hope this helps!

RecyclerView shows only one item even if there are many

I fetch data from database and put it to RecyclerView. My database arrives 4 items I see it with log debug then I send it to my adapter. However I see only first item on my screen.

I got 4 Objects from my database with command
articleList = dbHelper.getArticles();
However I see only first one on the screen.
Moreover as you see I loged in my adapter
#Override
public int getItemCount() {
// Log.d("list", "" + articleList.size());
return articleList.size();
}
That size also shows 4.

In item_list.xml, change android:layout_height="match_parent" with android:layout_height="wrap_content"

SearchView does not filter results with ListView

</menu>
This is how the view is. I want to filter the text in blue through searchview. Could anyone suggest how to do it?

You should filter list and call notifyDataSetChanged in adapter.
Example you have list ListA which contains ListA = {A,B,C}
You filter listA ( you search for item B ) FilteredList = {B}
AdapterSource = FilteredList
adapter.notifyDataSetChanged()
If you clear search view
AdapterSource = ListA

When I apply OnItemClickListener it does not do any action like intent inside the func not called. I tried toast too but nothing shown on clicking the listView Items.
I also tried OnItemSlectedListener , it also not worked for me.
What is the problem here with this code. ?

Thanks Every One. Issue was with autolink on email and phone, I make their focusable=false but nothing happened.Then I remove it and guess what? Clicklistener also starts working.

The attribute android:clickable="true" in your ListView could be overriding all of click events of its child views, you should probably remove it:
<ListView
android:clickable="true" <!-- Remove this attribute -->
android:id="#+id/listView_emp_directory_xml"
android:layout_below="#id/relatice_layout_header_emp_directory_activity_xml"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

Custom Adapter Not Printing Values

I am having some trouble with my custom adapter, the adapter is meant to print out |TextView|Button|EditText|Button|, It was working before I added in the button listeners, but when I added in the listeners the textView showed up blank.
I am also wondering if it is possible to keep the editText separate from row to row? As each row has buttons to increment or decrement their own running total, but when I press a button the total is carried to every row
Can anyone help me with these problems?
This is the adapter class I am using
import android.content.Context;
import android.database.Cursor;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.CursorAdapter;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;
import android.widget.TextView;
import com.pinchtapzoom.R;
public class CustomCursorAdapter extends CursorAdapter{
public int counter = 0;
public CustomCursorAdapter(Context context, Cursor c) {
super(context, c);
this.context = context;
}
Context context;
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
// when the view will be created for first time,
// we need to tell the adapters, how each item will look
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View retView = inflater.inflate(R.layout.row, parent, false);
return retView;
}
#Override
public void bindView(View view, Context context, Cursor cursor) {
// here we are setting our data
// that means, take the data from the cursor and put it in views
TextView textViewPersonName = (TextView) view.findViewById(R.id.item1);
textViewPersonName.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(1))));
}
public View getView(final int position, View convertView, ViewGroup parent)
{
if (convertView == null)
{
LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
convertView = (RelativeLayout)inflater.inflate(R.layout.row, null);
}
final EditText edit1 = (EditText)convertView.findViewById(R.id.runningTotal);
Button plusButton = (Button) convertView.findViewById(R.id.plusButton);
plusButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
counter++;
edit1.setText(Integer.toString(counter));
}
});
//final EditText edit1 = (EditText)convertView.findViewById(R.id.runningTotal);
Button minusButton = (Button) convertView.findViewById(R.id.minusButton);
minusButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
counter--;
edit1.setText(Integer.toString(counter));
}
});
return convertView;
}
}
This is my XML code
<?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"
android:orientation="vertical">

android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/plusButton"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<EditText
android:id="#+id/runningTotal"
android:layout_width="wrap_content"

android:layout_height="wrap_content"
android:text="#string/minusButton"

There are some issues with layout xml, TextView position was specified,
<?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"

android:layout_alignParentStart="true"
android:textSize="30sp"
android:paddingBottom="5dp"/>
<Button
android:id="#+id/plusButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="plus"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/item1"
android:layout_toEndOf="#+id/item1"
android:layout_centerHorizontal="true" />
<EditText
android:id="#+id/runningTotal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/plusButton"
android:layout_toEndOf="#+id/plusButton"
android:layout_toLeftOf="#+id/minusButton"
android:layout_toStartOf="#+id/minusButton"
android:layout_marginRight="30dp" />
<Button
android:id="#+id/minusButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="minus"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
</RelativeLayout>
It is better though to use LinearLayout
<?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"

<TextView
android:id="#+id/item1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:text="item"
android:textSize="30sp" />
<Button
android:id="#+id/plusButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="8dp"
android:text="plus" />
<EditText
android:id="#+id/runningTotal"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginRight="8dp"
android:layout_weight="1" />

Custom List adapter in Fragment - android

Try adding this method in your adapter class: #Override public int getCount() { return shoppingList.size(); } And also try not to use same name for your list variable and model class. Hope this helps!
