Android RSS : ListView Master Detail – Download,Parse,Show Headlines [Open Activity]




Introduction

This is an android RSS Master Detail example with XmlPullParser,AsyncTask ,HttpURLConnection and ListView.We shall download RSS Feeds from a local website and then parse the feed.We then show parsed images and text news in our ListView. We shall handle ItemClicks for our ListView's ViewItems and open the detail activity,passing in details over there.

What we do :

  • Connect to Internet and make a HTTP GET request using HtttpURLConnection.
  • Download our data in the background thread.
  • WE use AsyncTask for our threading.
  • WE parse the downloaded xml feeds.
  • We shall be parsing using XmlPullParser.
  • We show our results in a ListView.
  • This is our master view.It has our ListView.
  • When a single ListView viewitem is clicked,we open detail activity.
  • The detail view shall show details of a single news feed,like title,description,date etc.
  • The website we shall be parsing was hosted locally and it was a dummy wordpress site.

Let's dive in at the deep end.

SECTION 1 : Our Dependencies and Manifest

Build.Gradle

  • Studio has added for us dependencies for AppCompat and Design support libraries.
  • Now lets add dependencies for CardView.
  • Our AdapterView shall consist of CardViews as our ViewItems.

 

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.tutorials.hp.listviewrssmdetail"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.3.0'
    compile 'com.android.support:design:23.3.0'
    compile 'com.android.support:cardview-v7:23.3.0'

}

 

 

AndroidManifest.xml

  • Remember we are downloading data from a network.
  • Hence we need to add permission to access the internet.
  • Or else Android won't allow us establish connection.

 

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.tutorials.hp.listviewrssmdetail">

    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity
            android:name=".m_DetailActivity.DetailActivity"
            android:label="Article Detail Activity"
            android:theme="@style/AppTheme.NoActionBar"></activity>
    </application>

</manifest>

 

 

SECTION 2 : Our Data Object

Article.java

  • Represents a single article.
  • The article shall have various properties like name,title,description,date etc.

 

package com.tutorials.hp.listviewrssmdetail.m_DataObject;

/**
 * Created by Oclemy on 6/13/2016 for ProgrammingWizards Channel and http://www.camposha.com.
 */
public class Article {

    String title,description,date,guid,link;

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public String getDate() {
        return date;
    }

    public void setDate(String date) {
        this.date = date;
    }

    public String getGuid() {
        return guid;
    }

    public void setGuid(String guid) {
        this.guid = guid;
    }

    public String getLink() {
        return link;
    }

    public void setLink(String link) {
        this.link = link;
    }
}

 

 

SECTION 3 : Our Networking and Parsing classes

Connector class

Main Responsibility : ESTABLISH CONNECTION.

  • Establishes connection to our server for us.
  • We then set up connection properties like Request method.
  • In this case we are making a HTTP GET request to our server.
  • We shall use HttpURLConnection so our only method shall return its instance .

 

package com.tutorials.hp.listviewrssmdetail.m_RSS;

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;

/**
 * Created by Oclemy on 6/13/2016 for ProgrammingWizards Channel and http://www.camposha.com.
 */
public class Connector {

    public static Object connect(String urlAddress)
    {
        try
        {
            URL url=new URL(urlAddress);
            HttpURLConnection con= (HttpURLConnection) url.openConnection();

            con.setRequestMethod("GET");
            con.setConnectTimeout(15000);
            con.setReadTimeout(15000);
            con.setDoInput(true);


            return con;

        } catch (MalformedURLException e) {
            e.printStackTrace();
            return ErrorTracker.WRONG_URL_FORMAT;

        } catch (IOException e) {
            e.printStackTrace();
            return ErrorTracker.CONNECTION_ERROR;
        }
    }
}

 

 

Downloader class

Main Responsibility : DOWNLOAD XML FEEDS.

  • We use our Connector class above to establish a connection.
  • If we have a connection then we download data XML feeds from server.
  • We download in background using AsyncTask to avoid freezing our user interface.
  • Meanwhile we show progress dialog while downloading.
  • We dismiss our progress dialog on completion.
  • Then we send this downloaded xml feeds to our Data Parser class for it to be processed.

 

package com.tutorials.hp.listviewrssmdetail.m_RSS;

import android.app.ProgressDialog;
import android.content.Context;
import android.os.AsyncTask;
import android.widget.ListView;
import android.widget.Toast;

import java.io.InputStream;
import java.net.HttpURLConnection;

/**

 */
public class Downloader extends AsyncTask<Void,Void,Object> {

    Context c;
    String urlAddress;
    ListView lv;

    ProgressDialog pd;

    public Downloader(Context c, String urlAddress, ListView lv) {
        this.c = c;
        this.urlAddress = urlAddress;
        this.lv = lv;
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pd=new ProgressDialog(c);
        pd.setTitle("Fetch Articles");
        pd.setMessage("Fetching...Please wait");
        pd.show();

    }

    @Override
    protected Object doInBackground(Void... params) {
        return this.downloadData();
    }

    @Override
    protected void onPostExecute(Object data) {
        super.onPostExecute(data);

        pd.dismiss();
        if(data.toString().startsWith("Error"))
        {
            Toast.makeText(c,data.toString(),Toast.LENGTH_SHORT).show();
        }else {
            //PARSER CLASS
            new RSSParser(c, (InputStream) data,lv).execute();

        }
    }

    private Object downloadData()
    {
        Object connection=Connector.connect(urlAddress);
        if(connection.toString().startsWith("Error"))
        {
            return connection.toString();
        }

        try
        {
            HttpURLConnection con= (HttpURLConnection) connection;
            int responseCode=con.getResponseCode();

            if(responseCode==con.HTTP_OK)
            {
                InputStream is=new BufferedInputStream(con.getInputStream());
                return is;
            }

            return ErrorTracker.RESPONSE_EROR+con.getResponseMessage();


        } catch (IOException e) {
            e.printStackTrace();
            return ErrorTracker.IO_EROR;
        }


    }




}














 

 

RSS Parser class

Main Responsibility : DOWNLOAD XML FEEDS.

  • It receives raw XML feeds from downloader class.
  • It then processes/parses these feeds.
  • We use XmlPullParser to parse the feeds.
  • It then fills an arraylist of Article Objects with our results.
  • It then sends this arraylist to adapter for binding purposes.

Error Tracker class

Main Responsibility : HELP US TRACK CONNECTION EXCEPTIONS AT RUNTIME

  •  Consists of constants that we shall display when we encounter error at runtime.

 

package com.tutorials.hp.listviewrssmdetail.m_RSS;

/**
 * Created by Oclemy on 6/13/2016 for ProgrammingWizards Channel and http://www.camposha.com.
 */

    public final static String WRONG_URL_FORMAT="Error : Wrong URL Format";
    public final static String CONNECTION_ERROR="Error : Unable To Establish Connection";
    public final static String IO_EROR="Error : Unable To Read";
    public final static String RESPONSE_EROR="Error : Bad Response - ";


}

 

 

SECTION 3 : Adapter class

Custom Adapter class

Main Responsibility : HELPS US BIND CUSTOM DATA TO LISTVIEW.

  • You can use one line of code to bind simple data to listview.
  • But for custom data like ours,we need an adapter to adapt it.
  • We shall use BaseAdapter as our Base class.
  • Our BaseAdapter subclass shall receive an arraylist and a context.

SECTION 4 : Our Activities

Detail Activity class.

Main Responsibility : DISPLAY SINGLE NEWS ARTICLE DETAILS

  • Data shall be passed via Bundle from MainActivity.
  • So we simply unpack that data.
  • Then show it in our views.

            }
        });
    }

}








 

 

MainActivity class.

Main Responsibility : LAUNCH OUR APP.

  • We shall reference the views like ListView and Floating action button here,from our XML Layouts.
  • We then execute our Downloader class when Floating action button is clicked.
  • We shall also define here our feeds url and parse the data.
