Bye ListView, Bye GridView, Bye RecyclerView, Hello to One View for all Lists : PlaceHolderView

Android View Evolution : PlaceHolderView

Implementing RecyclerView with dynamic content and adding listeners on each is a very irritating task. Lets leave animation alone, if we have to do it for nested Recyclers then it’s a nightmare. What if we had a very simple interface, with more power, without adapter implementation, and could replace ListView, GridView and RecyclerView with ease and simplicity.

Why PlaceHolderView?

  1. PlaceHolderView removes all the boilerplate code involved in setting the View adapters. The amazing fact is that there is no adapter to worry about.
  2. The code becomes extremely modular and works with the flexibility of putting annotations on any view and methods.
  3. NO findViewById, NO onClickListener ugly codes
  4. Awesome animations on the view items can be applied with just one line of code.
  5. Memory management is super easy with this library

Some Applications:

Brief code usage guide:

Step 1:

Add gradle dependency in the app’s build.gradle

dependencies {
    compile 'com.mindorks:placeholderview:0.2.7'

Step 2:

Add the PlaceHolderView in the res/layout/activity_main.xml


Step 3:

Create an item view res/layout/gallery_item_big.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""

Step 4:


public class ImageTypeBig {

    private ImageView imageView;

    private String mUlr;
    private Context mContext;
    private PlaceHolderView mPlaceHolderView;

    public ImageTypeBig(Context context, PlaceHolderView placeHolderView, String ulr) {
        mContext = context;
        mPlaceHolderView = placeHolderView;
        mUlr = ulr;

    private void onResolved() {

    private void onLongClick(){



  1. @Layout: Bind the XML layout with the class
  2. @View: Bind the variable with the view defined in the above layout
  3. @Click: Bind the OnClickListener to a view
  4. @LongClick: Bind the long click listerner to a view
  5. @Resolve: Any operation being performed on the view reference defined by @View should be annotated with @Resolve
  6. @Animate(Animation.ENTER_LEFT_DESC) : Sets the defined animations in the Animation class on this item view
  7. @NonReusable : Releases the view reference along with all the attached references in the view object. This view object should not be used again in the addView()

Step 5′: (Optional)

If PlaceHolderView with grid layout or staggered layout or any custom layout is required or any customization to the default configuration is required then use the Builder class provided.

// If customisation is Required then use Builder with the PlaceHolderView
      .setLayoutManager(new GridLayoutManager(this, 3));

Step 5:

In obtain a reference to the PlaceHolderView and add views in it.

PlaceHolderView mGalleryView = (PlaceHolderView)findViewById(;
       .addView(new ImageTypeBig(this.getApplicationContext(), mGalleryView, url1));
       .addView(new ImageTypeBig(this.getApplicationContext(), mGalleryView, url2));
       .addView(new ImageTypeBig(this.getApplicationContext(), mGalleryView, url3));
       .addView(new ImageTypeBig(this.getApplicationContext(), mGalleryView, url4));

That’s all folks! You are done with the creation and implementation.

Quite Simple huh!
