listview with imageview in Android Studio

listview with imageview in Android Studio - android

I am new with Android Studio, and I would like to try a listview with pictures on the left shown below. I managed to make such a list with a simple list item, but when I changed the simple item list with an ActivityList, it does not work anymore.
How can I change the ArrayList to combine imageviews with the names? I think it could be possible by using a new class which contains the imageview and name instead of strings.
Code:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView friendsListView = findViewById(R.id.friendListView);
final ArrayList<String> myFriends = new ArrayList<String>(asList("Mark","Jane","Sussy","Jan"));
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,android.R.layout.activity_list_item
, myFriends);
friendsListView.setAdapter(arrayAdapter);
friendsListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Toast.makeText(getApplicationContext(), "Hello " + myFriends.get(i), Toast.LENGTH_LONG).show();
}
});
}
}

You're right, you need to create a model class for your list item; this model class contains things that differ from item to item; for instance in your shared picture, a list item has a typical of a picture and a title; and so your model class.
Next, instead of having ArrayList<String>, use ArrayList<Item>; where Item is the model class
Third, you need to create a custom adapter that extends from ArrayAdapter<Item>; that is because you can't use the built-in list item layout "android.R.layout.activity_list_item", because it just offers you with a single string; and now you need to accompany a picture with it.
Below is a simple demo
Model class (Item.java)
class Item {
private int mPicture;
private String mTitle;
int getPicture() {
return mPicture;
}
Item(int picture, String title) {
mPicture = picture;
mTitle = title;
}
String getTitle() {
return mTitle;
}
}
List View Adapter (ListViewAdapter.java)
public class ListViewAdapter extends ArrayAdapter<Item> {
ListViewAdapter(#NonNull Context context, ArrayList<Item> items) {
super(context, 0, items);
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent) {
View listItem = convertView;
if (listItem == null) {
listItem = LayoutInflater.from(getContext()).inflate(R.layout.list_item, parent, false);
}
// Get the {#link Word} object located at this position in the list
Item currentItem = getItem(position);
ImageView picture = listItem.findViewById(R.id.IvPicture);
picture.setBackgroundResource(currentItem.getPicture());
TextView title = listItem.findViewById(R.id.tvTitle);
title.setText(currentItem.getTitle());
return listItem;
}
}
Activity class
public class MainActivity extends AppCompatActivity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ArrayList<Item> items = new ArrayList<>();
items.add(new Item(R.drawable.item1, "Item1"));
items.add(new Item(R.drawable.item2, "Item2"));
items.add(new Item(R.drawable.item3, "Item3"));
ListViewAdapter adapter = new ListViewAdapter(this, items);
ListView listView = findViewById(R.id.listView);
listView.setAdapter(adapter);
}
}
Activity Layout (activity_main.xml)
<?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:orientation="vertical">
<ListView
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</ListView>
</LinearLayout>
List item layout (list_item.xml)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/rootView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/IvPicture"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/tvTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="item" />
</LinearLayout>
You have to have 3 images into res/drawable named item1, item2, and item3
Hope this satisfies your need.

How to use ViewBinding in a RecyclerView Adapter with Interface and Cardview in android java?

i always mostly required Recycleview with viewbinding using interface in android java done any one help to do same ??

First of all put below code in build.Gradle(Module) in side android brackets
buildFeatures{
viewBinding true
}
Step 1 - Create recycler view in main activity xml layout
<?xml version="1.0" encoding="utf-8"?>
<!-- 1 -->
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recycle_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
></androidx.recyclerview.widget.RecyclerView>
</RelativeLayout>
Step 2 - Create custom item layout xml By Right click on layout new -> layout Resource file
<?xml version="1.0" encoding="utf-8"?>
<!-- 2 -->
<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/card_click"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardElevation="3dp"
app:cardCornerRadius="10dp"
app:cardUseCompatPadding="true"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<ImageView
android:id="#+id/tv_logo"
android:src="#color/black"
android:padding="5dp"
android:layout_width="100dp"
android:layout_height="100dp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="5dp">
<TextView
android:id="#+id/tv_title"
android:text="Amazon"
android:textSize="25sp"
android:textStyle="bold"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<RatingBar
android:id="#+id/ratingBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:progressTint="#EFD80E"
android:rating="3"
style="#style/Widget.AppCompat.RatingBar.Indicator" />
</LinearLayout>
</LinearLayout>
</androidx.cardview.widget.CardView>
Step 3 - Create Item Class in java
package com.example.recyclerviewdemonewwithinterface.model;
// 3
public class Item {
private int id;
private String name;
private float rating;
private int image;
public Item(int id, String name, float rating, int image) {
this.id = id;
this.name = name;
this.rating = rating;
this.image = image;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public float getRating() {
return rating;
}
public void setRating(float rating) {
this.rating = rating;
}
public int getImage() {
return image;
}
public void setImage(int image) {
this.image = image;
}
}
Step 4 - Create CustomItemAdapter Class in java
package com.example.recyclerviewdemonewwithinterface.adapter;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.ViewGroup;
import android.widget.Toast;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
import com.example.recyclerviewdemonewwithinterface.SetOnClickListener;
import com.example.recyclerviewdemonewwithinterface.databinding.CustomItemLayoutBinding;
import com.example.recyclerviewdemonewwithinterface.model.Item;
import java.util.List;
// 4
public class CustomItemAdapter extends RecyclerView.Adapter<CustomItemAdapter.MyViewHolder> {
CustomItemLayoutBinding binding;
private Context context;
private List<Item> itemList;
// i3 & create constructor also
private SetOnClickListener setOnClickListener;
public CustomItemAdapter(Context context, List<Item> itemList, SetOnClickListener setOnClickListener) {
this.context = context;
this.itemList = itemList;
this.setOnClickListener = setOnClickListener;
}
#NonNull
#Override
public MyViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
binding = CustomItemLayoutBinding.inflate(LayoutInflater.from(context),parent,false);
MyViewHolder holder = new MyViewHolder(binding);
return holder;
}
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int position) {
Item item = itemList.get(position);
holder.binding.tvLogo.setImageResource(item.getImage());
holder.binding.tvTitle.setText(item.getName());
holder.binding.ratingBar.setRating(item.getRating());
// i4
holder.binding.cardClick.setOnClickListener(view -> {
setOnClickListener.onItemClick(item,position);
});
// click event from adapter
/*holder.binding.cardClick.setOnClickListener(v -> {
Toast.makeText(context, ""+item.getName(), Toast.LENGTH_SHORT).show();
});*/
}
#Override
public int getItemCount() {
return itemList.size();
}
class MyViewHolder extends RecyclerView.ViewHolder {
CustomItemLayoutBinding binding;
public MyViewHolder(#NonNull CustomItemLayoutBinding binding) {
super(binding.getRoot());
this.binding = binding;
}
}
}
Step 5 - Create SetOnClickListener Interface in java
package com.example.recyclerviewdemonewwithinterface;
import com.example.recyclerviewdemonewwithinterface.model.Item;
// 6
public interface SetOnClickListener {
// i1
void onItemClick(Item item,int position);
void onLongItemClick(Item item, int position);
}
Step 6 - Apply Below code in Main Activity Java
package com.example.recyclerviewdemonewwithinterface;
import android.os.Bundle;
import android.widget.Toast;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.LinearLayoutManager;
import com.example.recyclerviewdemonewwithinterface.adapter.CustomItemAdapter;
import com.example.recyclerviewdemonewwithinterface.databinding.ActivityMainBinding;
import com.example.recyclerviewdemonewwithinterface.model.Item;
import java.util.ArrayList;
import java.util.List;
// i2 & implement methods
public class MainActivity extends AppCompatActivity implements SetOnClickListener {
// 5
ActivityMainBinding binding;
List<Item> itemList;
CustomItemAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = ActivityMainBinding.inflate(getLayoutInflater());
setContentView(binding.getRoot());
prepareData();
// i5 set interface in argument (Last this)
adapter = new CustomItemAdapter(MainActivity.this, itemList, this);
LinearLayoutManager layoutManager = new LinearLayoutManager(MainActivity.this);
// to show listview horizontaly
// LinearLayoutManager layoutManager = new LinearLayoutManager(MainActivity.this,LinearLayoutManager.HORIZONTAL,false);
// to show grid view
// GridLayoutManager layoutManager = new GridLayoutManager(MainActivity.this,3);
// to show Straggered
// StaggeredGridLayoutManager layoutManager = new StaggeredGridLayoutManager(3,StaggeredGridLayoutManager.VERTICAL);
// layout manager in recycle view
binding.recycleView.setLayoutManager(layoutManager);
binding.recycleView.setAdapter(adapter);
}
private void prepareData() {
itemList = new ArrayList<>();
itemList.add(new Item(1, "Instagram", 3.5f, R.drawable.ic_launcher_background));
itemList.add(new Item(2, "Pinterest", 2.5f, R.drawable.ic_launcher_background));
itemList.add(new Item(3, "YouTube", 3.f, R.drawable.ic_launcher_background));
itemList.add(new Item(4, "Twitter", 5.5f, R.drawable.ic_launcher_background));
itemList.add(new Item(5, "Whatsapp", 4.5f, R.drawable.ic_launcher_background));
}
#Override
public void onItemClick(Item item, int position) {
// i6
// Toast.makeText(this, ""+itemList.get(position).getName(), Toast.LENGTH_SHORT).show();
//
Toast.makeText(this, "" + item.getId()+"___"+position, Toast.LENGTH_SHORT).show();
}
#Override
public void onLongItemClick(Item item, int position) {
}
}

Your problem is with your for cycle. You are adding nullable values to your list:
for (int i = 0; i <= 3; i++) {
new Listitem(
head[i],
desc[i]);
Listitem listitem = null;
listitems.add(listitem);
}
It should be:
for (int i = 0; i <= 3; i++) {
Listitem listitem = new Listitem(
head[i],
desc[i]);
listitems.add(listitem);
}

How do I add the value from textview to list view

I m trying to add the value from textview dynamically to listview.For that I have created another layout to take the values from user. but I'm not able to do that. I have tried many things. Kindly help.. Here is my code.
package com.example.chetan.assignment;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ListAdapter;
import android.widget.ListView;
import java.util.ArrayList;
import java.util.List;
public class MainActivity extends AppCompatActivity {
private static int count = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// String[] name= {"Apple","Banana","Mango","PineApple"};
//String[] price = {"Rs.40","Rs.60","Rs.70","Rs.80"};
List<String> names = new ArrayList<String>();
//String[] names = {"names"};
List<String> prices = new ArrayList<String>();
//String[] prices = {"prices"};
String name = getIntent().getStringExtra("name");
String price = getIntent().getStringExtra("price");
if(count==0) {
names.add(0, "name");
prices.add(0, "price");
}
if (count>0) {
names.add(count, name);
prices.add(count,price);
}
count++;
ListAdapter MyAdapter = new MyAdapter(names, prices, this);
ListView theList = (ListView) findViewById(R.id.listView);
theList.setAdapter(MyAdapter);
}
public void buttonClick(View view) {
Intent i = new Intent(this, Addlayout.class);
startActivity(i);
}
}
package com.example.chetan.assignment;
package com.example.chetan.assignment;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.BaseAdapter;
import android.widget.TextView;
class MyAdapter extends BaseAdapter {
String[] name;
String[] price;
Context context;
private static LayoutInflater myInflater = null;
public MyAdapter(String[] name, String[] price, Context context) {
this.name = name;
this.price = price;
this.context = context;
myInflater = ( LayoutInflater )context.
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return name.length;
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
public class Holder
{
TextView nametext;
TextView pricetext;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
Holder myholder = new Holder();
View myViews = myInflater.inflate(R.layout.myview,parent,false);
myholder.nametext= (TextView) myViews.findViewById(R.id.textView);
myholder.pricetext= (TextView) myViews.findViewById(R.id.textView2);
myholder.nametext.setText(name[position]);
myholder.pricetext.setText(price[position]);
return myViews;
}
}
package com.example.chetan.assignment;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Editable;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;
public class Addlayout extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_addlayout);
}
public void Onclickbutton(View view){
EditText nametext = (EditText)findViewById(R.id.editText);
EditText pricetext = (EditText)findViewById(R.id.editText2);
String namedata = nametext.getText().toString();
String pricedata = pricetext.getText().toString();
Intent intent = new Intent(this,MainActivity.class);
intent.putExtra("name",namedata);
intent.putExtra("price",pricedata);
startActivity(intent);
}
}

Here you can do something like this:
Instead of simple listview I have used RecyclerView as it has better performance.
//First create a Data class for name and price
public class Data implements Serializable {
private String name,price;
public Data(){}
public Data(String name,String price){
this.name = name;
this.price = price;
}
public String getPrice() {
return price;
}
public void setPrice(String price) {
this.price = price;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
//your Addlayout class
public class Addlayout extends AppCompatActivity {
List<Data> dataList = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_addlayout);
}
public void Onclickbutton(View view){
EditText nameText = (EditText)findViewById(R.id.editText);
EditText priceText = (EditText)findViewById(R.id.editText2);
String nameData = nameText.getText().toString();
String priceData = priceText.getText().toString();
Data data = new Data(nameData, priceData);
dataList.add(data);
Intent intent = new Intent(this,MainActivity.class);
intent.putExtra("List", (Serializable) dataList);
startActivity(intent);
}
}
//add layout xml
//change layout according to you
<?xml version="1.0" encoding="utf-8"?>

//Then your Listview Adapter

But in a listview it is only showing the package name not itemname and price.

Log.i("positin","position = "+String.valueOf(position));
dbHandler = new MyDBHandler(this,null,null,6);
Cart[] carts = dbHandler.databaseToArray(position);
for (Cart c : carts)
Log.i("jhnbvb1","item1 = "+c.getItemname()+" price1 = "+c.getPrice());
ListAdapter buckysAdapter = new ArrayAdapter<Cart>(this, android.R.layout.simple_list_item_1, carts);
ListView buckysListView = (ListView) findViewById(R.id.buckysListView2);
buckysListView.setAdapter(buckysAdapter);

You use standard ArrayAdapter instead of that one created by you. It should be
CustomAdapter2<Cart> buckysAdapter = new CustomAdapter2<Cart>(this, carts);
And array adapter itself should be modified:
public class CustomAdapter2 extends ArrayAdapter<Cart> {
private final List<Object> foods;
public CustomAdapter2(Context context, List<Cart> foods) {
super(context, 0);
this.foods = foods;
}
#Override
public int getCount() {
return foods.size();
}
#Override
public Cart getItem(int position) {
return foods.get(position);
}
//your getView
}

Android: CustomListView with CustomAdapter, Call Button is not working

In my app I have 3 views
ImagiveView
TextView
Button
ImagView displays image accordingly, TextView and Button display names and number accordingly. But the problem is when I click on the button it does not call to the number which is displaying on the button. Although it does open the android caller app.
Telephone numbers are in string.xml file.
Here I provide my all files. Please help me
strings.xml

you forgot to initialize the telephones string in your MainActivity, do same as you did for movie_poster_resource after this it should work, and dont forgot to add permission
<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>
and last you can update the button click code with
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:"+dataProvider.getTelePhone()));
startActivity(callIntent);
and update your AdapterClass with this
public class MoviesAdapter extends ArrayAdapter {
List list = new ArrayList();
public MoviesAdapter(Context context, int resource) {
super(context, resource);
}
static class DataHandler {
ImageView Poster;
TextView title;
Button telePhone;
}
#Override
public void add(Object object) {
super.add(object);
list.add(object);
}
#Override
public int getCount() {
return this.list.size();
}
#Override
public Object getItem(int position) {
return this.list.get(position);
}
#Override
public View getView(int position, View convertView, final ViewGroup parent) {
View row;
row = convertView;
final MovieDataProvider dataProvider = (MovieDataProvider) this.getItem(position);;
DataHandler handler;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.row_layout, parent, false);
handler = new DataHandler();
handler.Poster = (ImageView) row.findViewById(R.id.movie_poster);
handler.title = (TextView) row.findViewById(R.id.movie_title);
handler.telePhone = (Button) row.findViewById(R.id.btn_call);
} else {
handler = (DataHandler) row.getTag();
}
handler.Poster.setImageResource(dataProvider.getMovie_poster_resource());
handler.title.setText(dataProvider.getMovie_title());
handler.telePhone.setText(dataProvider.getTelePhone());
handler.telePhone.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:" + dataProvider.getTelePhone()));
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getContext().startActivity(intent);
}
});
row.setTag(handler);
return row;
}
}
