Load ImageView with bitmap from internet

It's a simple way to load ImageView with a bitmap from internet, via http connection.



In order to load something from internet, the AndroidManifest.xml have to be modified to grand permission for internet access.

     package="com.exercise.AndroidWebImage"
     android:versionCode="1"
     android:versionName="1.0">
   
                        android:label="@string/app_name">
           
               
               
           
       

   
   
 

Modify main.xml to include a ImageView

   android:orientation="vertical"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   >
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:text="@string/hello"
   />
   android:id="@+id/image"
   android:scaleType="center"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
/>

java code:

package com.exercise.AndroidWebImage;

import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.widget.ImageView;

public class AndroidWebImage extends Activity {

String image_URL=
 "https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgt-PXliYdaHrZj3fxAqPQ4Ka-pH9S-wJl7dwzIb2iF0yXpwfSv5QK9zkEkMZ_C_-rvvCQWHOOzPBP7lOBWLzp9gpI2zQE_ofuTIJOPWrEabGVtq1AEkwAmpdNY16kDemv3jyhWhEPlvnKx/s1600-r/android.png";

   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);

       ImageView bmImage = (ImageView)findViewById(R.id.image);
    BitmapFactory.Options bmOptions;
    bmOptions = new BitmapFactory.Options();
    bmOptions.inSampleSize = 1;
    Bitmap bm = LoadImage(image_URL, bmOptions);
    bmImage.setImageBitmap(bm);
   }
  
   private Bitmap LoadImage(String URL, BitmapFactory.Options options)
   {       
    Bitmap bitmap = null;
    InputStream in = null;       
       try {
           in = OpenHttpConnection(URL);
           bitmap = BitmapFactory.decodeStream(in, null, options);
           in.close();
       } catch (IOException e1) {
       }
       return bitmap;               
   }

private InputStream OpenHttpConnection(String strURL) throws IOException{
 InputStream inputStream = null;
 URL url = new URL(strURL);
 URLConnection conn = url.openConnection();

 try{
  HttpURLConnection httpConn = (HttpURLConnection)conn;
  httpConn.setRequestMethod("GET");
  httpConn.connect();

  if (httpConn.getResponseCode() == HttpURLConnection.HTTP_OK) {
   inputStream = httpConn.getInputStream();
  }
 }
 catch (Exception ex)
 {
 }
 return inputStream;
}
