Here is my Fab Activity
public class Fab extends FloatingActionButton implements AnimatedFab {
public Fab(Context context) {
super(context);
}
@Override
public void show() {
show(0, 0);
}
@SuppressLint("RestrictedApi")
@Override
public void show(float translationX, float translationY) {
setVisibility(View.VISIBLE);
}
/**
* Hides the FAB.
*/
@SuppressLint("RestrictedApi")
@Override
public void hide() {
setVisibility(View.INVISIBLE);
}
}
Here is my Main Activity
// MATERIAL ANIMATED FAB
Fab fab = findViewById(R.id.fab);
View sheetView = findViewById(R.id.fab_sheet);
View overlay = findViewById(R.id.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);
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.
}
});
Here is my logcat
