RecyclerView With Android DataBinding

In I/O 2015 Google announced a data binding library for Android. With Data Binding, you create an ongoing link between an element in the user interface and a value. Data Binding is the process that establishes a connection between the application UI and business logic.

In this post we will learn how to integrate recyclerview with android Data Binding.

Step 1 : Enable dataBinding in your module level gradle, here is how your build.gradle should look like.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.androidgig.recyclerviewbinding"
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        dataBinding{
            enabled true
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.android.support:recyclerview-v7:23.4.0'
    compile 'com.squareup.picasso:picasso:2.5.2'
}

apply plugin: 'com.android.application'

android {

compileSdkVersion 24

buildToolsVersion "23.0.3"

defaultConfig {

applicationId "com.androidgig.recyclerviewbinding"

minSdkVersion 15

targetSdkVersion 24

versionCode 1

versionName "1.0"

dataBinding{

enabled true

}

buildTypes {

release {

minifyEnabled false

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

}

dependencies {

compile fileTree(dir: 'libs', include: ['*.jar'])

compile 'com.android.support:appcompat-v7:23.4.0'

compile 'com.android.support:recyclerview-v7:23.4.0'

compile 'com.squareup.picasso:picasso:2.5.2'

}

Two-way DataBinding in Android

In the earlier posts we have seen how to use DataBinding, Setting custom font and Image loading. Today we will discuss about two-way DataBinding.

What is Two-way DataBinding?

Till now we have seen how to set values to xml view, but in controls like EditText we need to fetch value. In simple term two-way DataBinding is setting values to that control and fetching it after having some changes.

ObservableField

ObservableField can be used instead of extending BaseObservable class. ObservableFields are self-contained observable objects that have a single field.

Image Loading With DataBinding in Android

We have already seen DataBinding Basics and setting fonts through DataBinding in previous tutorials. Today we will take a look at Image loading with databinding .

Step 1 : Define POJO/Model class

public class PersonModelClass
{
    String name,designation,image_url;

    public PersonModelClass(String name, String designation, String image_url) {
        this.name = name;
        this.designation = designation;
        this.image_url = image_url;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getDesignation() {
        return designation;
    }

    public void setDesignation(String designation) {
        this.designation = designation;
    }

    public String getImage_url() {
        return image_url;
    }

    public void setImage_url(String image_url) {
        this.image_url = image_url;
    }
}

public class PersonModelClass

{

String name,designation,image_url;

public PersonModelClass(String name, String designation, String image_url) {

this.name = name;

this.designation = designation;

this.image_url = image_url;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getDesignation() {

return designation;

}

public void setDesignation(String designation) {

this.designation = designation;

}

public String getImage_url() {

return image_url;

}

public void setImage_url(String image_url) {

this.image_url = image_url;

}
