Use BottomSheetDialog in design support library. An example below.

        BottomSheetDialog mBottomSheetDialog = new BottomSheetDialog(this);
        View view = getLayoutInflater().inflate(R.layout.your_layout, null);
        mBottomSheetDialog.setContentView(view);
        mBottomSheetDialog.show();
