Some Implementations

Documentation

You can find the PlaceHolderView documentation here which has extended usage instructions and other useful information.

About PlaceHolderView

Some of the views in PlaceHolderView library is build on top of RecyclerView and rest are written in its own.

All the annotations are processed during build time to generate the binding classes

There are two versions available for use.

1. Old version (branch 1.x): Uses Java reflection
2. New version (branch 2.x): Uses Annotation Processing.

This library provides 5 different type of views

1. PlaceHolderView
   It is build on top of RecyclerView and abstracts most of the boiler plate. It provides APIs through annotations.

2. InfinitePlaceHolderView
   It is build on PlaceHolderView and adds the functionality of handling load more views when the user has scrolled to the bottom of the list.

3. ExpandablePlaceHolderView
   It is build on PlaceHolderView and creates ExpandableListView with parent-child relation.

4. SwipePlaceHolderView
   It is not build on RecyclerView. Its a ground up implementation. We can create a variety of card stack views using this class. It provides APIs that could easily build Tinder like cards.

5. SwipeDirectionalView
   It is build on top of SwipePlaceHolderView. It provides callbacks for swipe directions and touch events.

How to use newer version (2.x branch) with annotation processing

Gradle dependency:

Java

dependencies {
    ...
    compile 'com.mindorks.android:placeholderview:1.0.3'
    annotationProcessor 'com.mindorks.android:placeholderview-compiler:1.0.3'

    // RecyclerView dependency is added to override the
    // default 25.4.1 RecyclerView dependency used by placeholderview.
    // If you are using the support libraries other than 25.x in the project
    compile 'com.android.support:recyclerview-v7:<current-version>' // example: 27.1.0
}

Kotlin

dependencies {
    ...
    // RecyclerView dependency is added to override the
    // default 25.4.1 RecyclerView dependency stated by placeholderview
    // since we are using the 27.+ support libraries in the project
    implementation 'com.android.support:recyclerview-v7:27.1.0'
    implementation 'com.mindorks.android:placeholderview:1.0.3'
    kapt 'com.mindorks.android:placeholderview-compiler:1.0.3'
}

For use with Kotlin refer to Kotlin docs.

Migration:

It is super easy to migrate to 2.x branch library version.

To migrate from 1.x to 2.x see Migration doc here.

How to Use older version (1.x branch)

If you want to use older version of PlaceHoldeView that used reflection, then you can use below dependecies.

Gradle dependency:

dependencies {
    compile 'com.mindorks:placeholderview:0.7.3'
}

Dependency: It depends on the RecyclerView

Add below lines in your app's build.gradle if recyclerview above v7:25 is being used

    // NOTE: change the version of recyclerview same as the your project's support library version
    com.android.support:recyclerview-v7:25.+

Proguard Note:

If you are using proguard, then add this rule in proguard-project.txt

  -keepattributes *Annotation*
  -keepclassmembers class ** {
    @com.mindorks.placeholderview.annotations.** <methods>;
  }
