Android library for inflating dynamic layouts in runtime based on JSON configuration fetched from server. Useful in situations when layouts need to change without updating the app.

• Targeting specific devices by brand, model and Android API version
• Layout changes based on configuration fields

1. Add repository in root build.gradle

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
    }
}

2. Add the dependency

dependencies {
    compile 'com.github.jelic98:dynamico:1.2.0'
}

1. Create JSON layout and upload it somewhere

{
  "views":[  
    {  
      "class":"android.widget.ImageView",
      "attributes":{  
        "layout_width":"wrap_content",
        "layout_height":"wrap_content",
        "src":"https://lazarjelic.com/ecloga/projects/dynamico/logo.png",
        "cache":true
      }
    },
    {  
      "class":"android.widget.TextView",
      "attributes":{  
        "text":"Yo!",
        "textColor":"#FF69B4"
      }
    }
  ]
}

2. Create XML wrapper layout that will contain loaded views

<?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="match_parent"
	android:orientation="vertical"
	android:id="@+id/mainLayout">
		
	<!-- Dynamic content will be added here -->
</LinearLayout>

3. Initialize Dynamico by passing it:

• URL = Link to JSON layout directory
• name = Name of JSON layout file
• layout = Wrapper layout that will contain loaded views

new Dynamico("https://lazarjelic.com/ecloga/projects/dynamico",
    "activity_main",
    findViewById(R.id.mainLayout))
    .initialize();

For advanced usage, take a look at this awesome manual.

• Event listener

setListener(new LayoutStateListener() {
	@Override
	public void onSuccess(String message) {
		// everything is okay
	}
	
	@Override
	public void onError(String message) {
		// notify user
	}
})

• Loading from cache (skip layout fetching from server)

setOptions(CACHE_ONLY)

• Non-stop layout fetching

setOptions(NON_STOP) // use with setAsyncPause(long millis)

One and only constructor

• Parameters:
  • url — URL of directory where JSON layout file is located (for example, "https://lazarjelic.com/ecloga/projects/dynamico")
  • name — JSON layout file name with or without extension (for example, "activity_main")
  • layout — wrapper layout that will contain inflated layout from JSON file (for example, findViewById(R.id.mainLayout))
• Exceptions: DynamicoException — if any of passed parameters is null

Attaches event listener to Dynamico object

• Parameters: listener — listener for success and error events caused by network, storage, etc.
• Returns: Dynamico object ready for initialization

Attaches options to Dynamico object

• Parameters: options — options for Dynamico (for example, ONLY_CACHE)
• Returns: Dynamico object ready for initialization

Starts layout fetching from cache/server depending on provided options

• Support vector drawables
• Support more views
