MaterialSheetFab

Library that implements the floating action button to sheet transition from Google's Material Design documentation. It can be used with any FAB library on Android 4.0+ (API levels >= 14).

Installation

Gradle

Add the dependency (available from mavenCentral and jcenter) to your build.gradle:

implementation 'com.gordonwong:material-sheet-fab:1.2.1'

Proguard

Modify your proguard configuration (if your app is using Proguard).

-keep class io.codetail.animation.arcanimator.** { *; }

Usage

Implement the FAB:

You can use any FAB library as long as it implements the AnimatedFab interface.

import android.support.design.widget.FloatingActionButton;

public class Fab extends FloatingActionButton implements AnimatedFab {

   /**
    * Shows the FAB.
    */
    @Override
    public void show() {
        show(0, 0);
    }

    /**
     * Shows the FAB and sets the FAB's translation.
     *
     * @param translationX translation X value
     * @param translationY translation Y value
     */
    @Override
    public void show(float translationX, float translationY) {
        // NOTE: Using the parameters is only needed if you want
        // to support moving the FAB around the screen.
        // NOTE: This immediately hides the FAB. An animation can 
        // be used instead - see the sample app.
        setVisibility(View.VISIBLE);
    }

    /**
     * Hides the FAB.
     */
    @Override
    public void hide() {
        // NOTE: This immediately hides the FAB. An animation can
        // be used instead - see the sample app.
        setVisibility(View.INVISIBLE);
    }
}

Modify the layouts:

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

   <!-- Your FAB implementation -->
   <path.to.your.fab
        android:id="@+id/fab"
        android:layout_alignParentBottom="true"
        android:layout_alignParentEnd="true"
        android:layout_alignParentRight="true" />

    <!-- Overlay that dims the screen -->
    <com.gordonwong.materialsheetfab.DimOverlayFrameLayout
        android:id="@+id/overlay"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!-- Circular reveal container for the sheet -->
    <io.codetail.widget.RevealLinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="end|bottom"
        android:orientation="vertical">

        <!-- Sheet that contains your items -->
        <android.support.v7.widget.CardView
            android:id="@+id/fab_sheet"
            android:layout_width="250dp"
            android:layout_height="300dp">
            
            <!-- TODO: Put your sheet items here -->
            
        </android.support.v7.widget.CardView>
    </io.codetail.widget.RevealLinearLayout>
</RelativeLayout>

Initialize the MaterialSheetFab:

This can be in your Activity or Fragment.

public class MaterialSheetFabActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Fab fab = (Fab) findViewById(R.id.fab);
        View sheetView = findViewById(R.id.fab_sheet);
        View overlay = findViewById(R.id.dim_overlay);
        int sheetColor = getResources().getColor(R.color.fab_sheet_color);
        int fabColor = getResources().getColor(R.color.fab_color);

        // Initialize material sheet FAB
        materialSheetFab = new MaterialSheetFab<>(fab, sheetView, overlay,
            sheetColor, fabColor);
    }
}

Optional:

Close sheet on back button:

@Override
public void onBackPressed() {
    if (materialSheetFab.isSheetVisible()) {
        materialSheetFab.hideSheet();
    } else {
        super.onBackPressed();
    }
}

Listen to events:

materialSheetFab.setEventListener(new MaterialSheetFabEventListener() {
    @Override
    public void onShowSheet() {
        // Called when the material sheet's "show" animation starts.
    }
    
    @Override
    public void onSheetShown() {
        // Called when the material sheet's "show" animation ends.
    }

    @Override
    public void onHideSheet() {
        // Called when the material sheet's "hide" animation starts.
    }
     
    public void onSheetHidden() {
        // Called when the material sheet's "hide" animation ends.
    }
});

Move the FAB around the screen (this is useful for coordinating with snackbars):

materialSheetFab.showFab(translationX, translationY);
