Show and Hide Bottom Sheet Programmatically

Question

I have implemented Bottom Sheet functionality within my activity in onCreate() using this solution and this library

   sheet = new BottomSheet.Builder(this,          


        

Answer 1

To close the BottomSheetDialogFragment from inside the fragment you can call:

dismiss();

To show or hide the BottomSheetDialogFragment from the activity you can simply call:

bottomSheetDialogFragment.dismiss();//to hide it
bottomSheetDialogFragment.show(getSupportFragmentManager(),tag);// to show it

Answer 2

use the following code

new BottomSheet.Builder(getActivity()).title("Your Title here").sheet(R.menu.bottom_sheet).listener(new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                switch (which) {
                    case R.id.cancel:
                        dialog.cancel();
                        break;
                    case R.id.view:
                        //Todo view code here
                        dialog.cancel();
                        break;
                }
            }
        }).show();

Answer 3

For showing the Bottom Sheet use this code:

bottomSheetInfoBehavior.setHideable(false);
bottomSheetInfoBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);

For Hiding the Bottom sheet use this code:

bottomSheetInfoBehavior.setHideable(true);
bottomSheetInfoBehavior.setState(BottomSheetBehavior.STATE_HIDDEN);

Answer 4

Inside your onClick() of the button use: sheet.show().

Then when you want to dismiss it, use sheet.dismiss();

Here below a possible solution:

BottomSheet sheet = new BottomSheet.Builder(...).build();
Button button = (Button)findViewById(R.id.mybutton);
button.setOnClickListener(new OnClickListener(){
    @Override
    public void onClick(View v) {
        //you can use isShowing() because BottomSheet inherit from Dialog class
        if (sheet.isShowing()){
            sheet.dismiss();
        } else {
            sheet.show();    
        }
    }
});
