Android code to fetch Image from server and display it in Imageview

Question

Hi I know how to fetch an string from jsonobject, but my question is how to fetch an image from Rest api and display it. The image is stored as profile_image in jsonobject

Answer 1

This can be done using Picasso

for that add dependancy in build.gradle file of your project

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile 'com.android.support:design:23.0.1'
    compile 'com.squareup.picasso:picasso:2.4.0'
}

and add code in your method as below

if(object.has("profile_image")) {
    // imageView should be declared in layout xml file with id `imageView`
    ImageView imageView = (ImageView) context.findViewById(R.id.imageView);
    com.squareup.picasso.Picasso.with(context).
        load(object.get("profile_image")).
        placeholder(R.mipmap.ic_launcher).
        into(imageView);
}

and done.

NOTE : object.get("profile_image") should return full path of image.

for e.g. http://www.example.com/images/image1.jpg

then only it will work.
