URL :- https://api.androidhive.info/json/movies.json
Get data two Image and title from URL
Step 1 : Create a new project in Android studio IDE File ⇒ New ⇒ Android Application Project and fill all the required details.
Step 2 : In xml file place List view and image view code below.
Step 3 : Add Internet Permission in your project manifest file .
<uses-permission android:name="android.permission.INTERNET" />
Step 4 : Create XML file named activity_main.xml
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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="com.example.webbleu8.ok.MainActivity">
<ListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ListView>
</LinearLayout>
-------------------------------------------------------------------------------------------------------------
STEP 5 : Create Xml file named custom_item.xml
custom_item
<?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="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="@+id/image"
android:layout_width="200dp"
android:layout_height="100dp"
android:scaleType="fitXY" />
<TextView
android:id="@+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:textColor="#000000" />
</LinearLayout>
------------------------------------------------------------------------------------------------
STEP 6 : Create Main_activity.java and declare necessary variables for the list view.
Main_Activity.java
package com.example.webbleu8.ok;
import android.app.ProgressDialog;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.AsyncTask;

import android.util.Log;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Adapter;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
import com.squareup.picasso.Picasso;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import java.io.IOException;

import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
ArrayList<String> genre = new ArrayList<>();
ArrayList<model> list;
ListView listView;
ProgressDialog pDialog;
AppAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
adapter = new AppAdapter();
pDialog = new ProgressDialog(MainActivity.this);
list = new ArrayList<>();
listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(adapter);
new GetContacts().execute();
}
private class GetContacts extends AsyncTask<Void, Void, Void> {
String url = "https://api.androidhive.info/json/movies.json";
String title, image, rating, year;
@Override
protected void onPreExecute() {
super.onPreExecute();
// Showing progress dialog
pDialog.setMessage("Please wait...");
pDialog.setCancelable(false);
pDialog.show();
}
@Override
protected Void doInBackground(Void... arg0) {
HttpHandler sh = new HttpHandler();
// Making a request to url and getting response
String jsonStr = sh.makeServiceCall(url);
if (jsonStr != null) {
try {
// Getting JSON Array node
JSONArray contacts = new JSONArray(jsonStr);
// looping through All Contacts
genre.clear();
list.clear();
for (int i = 0; i < contacts.length(); i++) {
JSONObject c = contacts.getJSONObject(i);
title = c.getString("title");
image = c.getString("image");
rating = c.getString("rating");
year = c.getString("releaseYear");
JSONArray jsonArray = c.getJSONArray("genre");
/* for (int j = 0; j < jsonArray.length(); j++) {
genre.add(jsonArray.getString(j));
}*/
/*System.out.println(" genre array " + genre);*/
model model = new model();
model.setTitle(title);
model.setImage(image);
list.add(model);
System.out.println(" Title " + title);
System.out.println(" rating " + rating);
System.out.println(" release year " + year);
System.out.println("Image " + image);
}
Log.d("ARRAY>> ", "" + list.size());
} catch (final JSONException e) {
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(), "Json parsing error: " + e.getMessage(), Toast.LENGTH_LONG).show();
}
});
}
} else {
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(), "Couldn't get json from server. Check LogCat for possible errors!", Toast.LENGTH_LONG).show();
}
});
}
return null;
}
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
// Dismiss the progress dialog
if (pDialog.isShowing())
pDialog.dismiss();
adapter.notifyDataSetChanged();
System.out.println("Image_path==================" + image);
}
}
private class AppAdapter extends BaseAdapter {
@Override
public int getCount() {
return list.size();
}
@Override
public model getItem(int position) {
return list.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = View.inflate(getApplicationContext(), R.layout.custom_item, null);
new ViewHolder(convertView);
}
final ViewHolder holder = (ViewHolder) convertView.getTag();
final model model = getItem(position);
holder.text.setText(model.getTitle());
Picasso.with(getApplicationContext()).load(model.getImage()).into(holder.image);
return convertView;
}
class ViewHolder {
TextView text;
ImageView image;
ViewHolder(View view) {
text = (TextView) view.findViewById(R.id.text);
image = (ImageView) view.findViewById(R.id.image);
view.setTag(this);
}
}
}
}
STEP 7 : Create Model.java class for get perticular data (image, Title)
model.java
package com.example.webbleu8.ok;
public class model {
String title, image;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
}
Create HTTPURLConnection .java
HTTPURLConnection.java
package com.example.webbleu8.ok;
import android.util.Log;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.UnsupportedEncodingException;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;
import java.util.HashMap;
import java.util.Map;
import javax.net.ssl.HttpsURLConnection;
public class HTTPURLConnection
{
String response="";
URL url;
public String ServerData(String path, HashMap<String, String> params)
{
try
{
url = new URL(path);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(15000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(getPostDataString(params));
writer.flush();
writer.close();
os.close();
int responseCode = conn.getResponseCode();
if (responseCode == HttpsURLConnection.HTTP_OK) {
String line;
BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
while ((line = br.readLine()) != null) {
response += line;
Log.d("output lines", line);
}
} else {
response = "";
}
} catch (Exception e) {
e.printStackTrace();
}
return response;
}
private String getPostDataString(HashMap<String, String> params) throws UnsupportedEncodingException {
StringBuilder result = new StringBuilder();
boolean first = true;
for(Map.Entry<String, String> entry : params.entrySet()){
if (first)
first = false;
else
result.append("&");
result.append(URLEncoder.encode(entry.getKey(), "UTF-8"));
result.append("=");
result.append(URLEncoder.encode(entry.getValue(), "UTF-8"));
}
return result.toString();
}
}
Create a class HttpHandler.java and fetch particular URL and fetch the response
HttpHandler.java
package com.example.webbleu8.ok;
import android.util.Log;
import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.ProtocolException;
import java.net.URL;
public class HttpHandler
{
private static final String TAG = HttpHandler.class.getSimpleName();
public HttpHandler() {
}
public String makeServiceCall(String reqUrl) {
String response = null;
try {
URL url = new URL(reqUrl);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
// read the response
InputStream in = new BufferedInputStream(conn.getInputStream());
response = convertStreamToString(in);
} catch (MalformedURLException e) {
Log.e(TAG, "MalformedURLException: " + e.getMessage());
} catch (ProtocolException e) {
Log.e(TAG, "ProtocolException: " + e.getMessage());
} catch (IOException e) {
Log.e(TAG, "IOException: " + e.getMessage());
} catch (Exception e) {
Log.e(TAG, "Exception: " + e.getMessage());
}
return response;
}
private String convertStreamToString(InputStream is)
{
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line;
try {
while ((line = reader.readLine()) != null)
{
sb.append(line).append('\n');
}
}
catch (IOException e)
{
e.printStackTrace();
} finally
{
try
{
is.close();
} catch (IOException e)
{
e.printStackTrace();
}
}
return sb.toString();
}
}
