build.gradle (Module: app)

dependencies { 
	implementation 'com.google.android.material:material:1.1.0' 
}

 

BottomSheetDialog 는 머티리얼 디자인이므로 의존성 추가

public class MainActivity extends AppCompatActivity {

    Button btnClick;
    Button btnOK;
    Button btnClose;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    }
}

 

val bottomSheetDialog = BottomSheetDialog(applicationContext)   -> 실행 후 버튼 클릭 시 에러 발생.

                bottomSheetDialog.dismiss();
            }
        });
