Simple RecyclerView Touch Listener RecyclerViewExtensions

Getting Started

Android library that abstracts, and completely hide, the GestureDetector part of an recyclerview click, and press, events implementation. Leaving to the developer only the task of implementing what happens when such events occurs. Compatible with androidx. See legacy code here

Pre-requisites

To be able of testing and implementing this library, the developer should have a working recyclerview list with some data on it. Please refer to the sample app.

Adding to your project

Lets start by adding a corresponding repository in your root build.gradle file.

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

The next task is to add the dependency to your app build.gradle file.

dependencies {
    ..
    implementation 'com.github.horaciocome1:simple-recyclerview-touch-listener$VERSION'
}

Now you ready to go. You may want to sync your project first.

How to use (0.3.0 onwards)

See legacy code here
Inside the block, use isSingleClick, isDoubleClick, and isLongClick to filter your event. Then use view and position to find the itemView and the itemPosition respectively.

recyclerView.addGestureDetection {
    Log.d(TAG, "addGestureDetection isSingleClick=$isSingleClick")
    Log.d(TAG, "addGestureDetection isDoubleClick=$isDoubleClick")
    Log.d(TAG, "addGestureDetection isLongPress=$isLongPress")
    Log.d(TAG, "addGestureDetection view=$view")
    Log.d(TAG, "addGestureDetection position=$position")
}

There are also overflows for each individual gesture type which are implemented like this:

recyclerView.addGestureDetection {
    Log.d(TAG, "gesture detected")
    singleClick {
        Log.d(TAG, "gesture is single click")
        Log.d(TAG, "view=$view")
        Log.d(TAG, "position=$position")
    }
}

recyclerView.addGestureDetection {
    doubleClick {
        ..
    }
}

recyclerView.addGestureDetection {
    longPress {
        ..
    }
}

Troubleshooting

1. You might face poor java support.
2. Would like to rollback to 0.2.0? See legacy code here
