FoldableActivity

Android library that simplifies the logic necessary to detect state changes in foldable devices,

Setup

1. Add the JitPack repository to your "settings.gradle" file if you didn't add before.

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

2. Add the dependency

dependencies {
    implementation 'com.github.WhiteDog-Apps:FoldableActivity_Android:1.0.4'
}

Usage

1. Make your activity inherit from FoldableActivity

class MainActivity: FoldableActivity() {
    ...
}

2. Implements members

    override fun getRootView(): View {
    // Return the view where you will control the fold
}

override fun onFoldablePostureChanged(foldPosture: FoldPosture, foldPositionFromEnd: Int) {
    // Update UI
}

Example

    // 1. Make your activity inherit from FoldableActivity
class MainActivity: FoldableActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }

    // 2. Implements members
    override fun getRootView(): View {
        return findViewById<ConstraintLayout>(R.id.motion_layout_guides_root)
    }

    override fun onFoldablePostureChanged(foldPosture: FoldPosture, foldPositionFromEnd: Int) {
        when(foldPosture) {
            FoldPosture.TABLE_TOP -> {
                ConstraintLayout.getSharedValues().fireNewValue(R.id.rg_motion_layout_guides_tabletop, foldPositionFromEnd)
                ConstraintLayout.getSharedValues().fireNewValue(R.id.rg_motion_layout_guides_book, 0)
            }
            FoldPosture.BOOK      -> {
                ConstraintLayout.getSharedValues().fireNewValue(R.id.rg_motion_layout_guides_tabletop, 0)
                ConstraintLayout.getSharedValues().fireNewValue(R.id.rg_motion_layout_guides_book, foldPositionFromEnd)
            }
            else                  -> {
                ConstraintLayout.getSharedValues().fireNewValue(R.id.rg_motion_layout_guides_tabletop, 0)
                ConstraintLayout.getSharedValues().fireNewValue(R.id.rg_motion_layout_guides_book, 0)
            }
        }
    }
}
