도와주세요 알고 있다면 당신은이를 추가해야한다

dialog.setOnShowListener(new OnShowListener() { 
    @Override 
    public void onShow(DialogInterface dialog) { 
    FrameLayout bottomSheet = dialog.getWindow() 
     .findViewById(android.support.design.R.id.design_bottom_sheet); 
    CoordinatorLayout coordinatorLayout = (CoordinatorLayout) bottomSheet.getParent(); 
    BottomSheetBehavior bottomSheetBehavior = BottomSheetBehavior.from(bottomSheet); 
    bottomSheetBehavior.setPeekHeight(bottomSheet.getHeight()); 
    coordinatorLayout.getParent().requestLayout(); 
    } 
}); 

이 코드는 자동으로 높이를 볼 높이를 조정합니다. 고정 된 높이를 원할 경우 bottomSheet.getHeight()을 원하는대로 변경하십시오.
