BottomSheetLayout

Simple bottom sheet view for Android

How to use ?

Install

Add this to your app build.gradle

dependencies {
    ...
    implementation 'com.qhutch.bottomsheetlayout:bottomsheetlayout:0.1.1'
}

XML

And this in your layout xml :

<com.qhutch.bottomsheetlayout.BottomSheetLayout
        android:id="@+id/bottom_sheet_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:collapsedHeight="80dp">
        
        ...
        
</com.qhutch.bottomsheetlayout.BottomSheetLayout>

And use as any Frame Layout

collapsedHeight is the height of the layout when collapsed (default is 0)

Java/(Kotlin)

You can use those methods on the layout :

BottomSheetLayout layout = (BottomSheetLayout) findViewById(R.id.bottom_sheet_layout);
...
layout.toggle(); //collapses or expands the view according to the current state
...
layout.collapse(); //collapses the view
...
layout.expand(); //expands the view
...
layout.isExpended(); //return true if the view is expanded

And if you want to track the progress :

(It may be usefull to animate views at the same time)

layout.setOnProgressListener(new BottomSheetLayout.OnProgressListener() {
            @Override
            public void onProgress(float progress) {
                doSomethingWithTheProgress(progress)
            }
        });

or in Kotlin :

layout.setOnProgressListener { progress -> doSomethingWithTheProgress(progress) }

progress is 0 when collapsed and 1 when expanded

TODO list:

⬜️ Add possibility to change animation time
⬜️ Compute time of end animation based on progress
⬜️ Option to disable touch to drag
