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, R.style.BottomSheet_Dialog)         .title("New")         .grid() // <-- important part         .sheet(R.menu.menu_bottom_sheet)         .listener(new DialogInterface.OnClickListener() {     @Override     public void onClick(DialogInterface dialog, int which) {         // TODO     } }).build(); 

Now, I would like to Show Bottom sheet, on click of button and in a same way want to hide bottom sheet on click of same button, if already Visible

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

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();             }     } });
