Dismiss a bottom sheet dialogue in android from its own Custom Activity

问题

I have created a custom bottom sheet android dialogue with the help of this answer by Chintan Khetiya:How to create a Custom Dialog box in android?.

I want to dismiss the dialogue from the button defined in the BottomDialogue's own Activity.Not from Calling activity.

Here is my code in the Calling activity in which i have created my custom BottomSheet_liab instance by click of a button:

openBottomDialogeButton.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View view) {
                   **//Creating the BottomDialogue Instance**`Bottomsheet_liab dialog;
    dialog=new Bottomsheet_liab(getActivity());
dialog.getWindow().setBackgroundDrawable(newColorDrawable(Color.TRANSPARENT));`

        }
    });

Here is my code in the dialogue activity:

public class Bottomsheet_liab extends BottomSheetDialog{
@Override
 protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.cashflow_bottomsheet);
         Button btn=(Button)findViewByID(R.id.btnx);
         btn.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View view) {
                   **//I want to dismiss this BottomSheetDialogue from here.How can I do this>**
        }
    });

}

Try this You need to call dismiss(); method like below code

btn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
      dismiss();
    }
});

sample code

public class Bottomsheet_liab extends BottomSheetDialog{
@Override
 protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.cashflow_bottomsheet);
         Button btn=(Button)findViewByID(R.id.btnx);
         btn.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View view) {
                   dismiss();
        }
    });

}

Try Following Code

private Button startbtn, okaybtn, cancelbtn;
BottomSheetDialog mBottomSheetDialog;
View sheetView;

    mBottomSheetDialog = new BottomSheetDialog(HomeActivity.this);
    sheetView = getLayoutInflater().inflate(R.layout.botomdialouge,null);
    mBottomSheetDialog.setContentView(sheetView);


    okaybtn = sheetView.findViewById(R.id.okaybtn);
    cancelbtn = sheetView.findViewById(R.id.cancelbtn);

   okaybtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            finish();
        }
    });

    cancelbtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mBottomSheetDialog.dismiss();
        }
    });
