how to set height of BottomSheet full parent?

Question

I am trying to call BottomSheet using android-support-library 23.2 on Click of button. Its working fine but not taking full height. It reside below AppBarLayout. I didn't find any solution on Android Documentation

This is my Screen layout

Here is my code.

activity_main.xml

            app:tabMode="fixed" />
    </android.support.design.widget.AppBarLayout>

    <android.support.v4.view.ViewPager

        app:layout_behavior="android.support.design.widget.BottomSheetBehavior">

    </FrameLayout>

</android.support.design.widget.CoordinatorLayout>

MainActivity.java

View bottomSheet;
private BottomSheetDialog mBottomSheetDialog;

private void initView(){
         /*
        Bottom Sheet Initialization
         */
        CoordinatorLayout coordinatorLayout = (CoordinatorLayout)findViewById(R.id.main_content);
        // The View with the BottomSheetBehavior
        bottomSheet = coordinatorLayout.findViewById(R.id.bottom_sheet);
        behavior = BottomSheetBehavior.from(bottomSheet);
//        behavior.setState(BottomSheetBehavior.STATE_HIDDEN);
        behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
            @Override
            public void onStateChanged(@NonNull View bottomSheet, int newState) {
                // React to state change
                CommonMethods.getInstance().e("onStateChanged", "onStateChanged:" + newState);
                if (newState == BottomSheetBehavior.STATE_EXPANDED) {
                    fab.setVisibility(View.GONE);
                } else {
                    fab.setVisibility(View.VISIBLE);
                }
            }

            @Override
            public void onSlide(@NonNull View bottomSheet, float slideOffset) {
                // React to dragging events
                CommonMethods.getInstance().e("onSlide", "onSlide");
            }
        });

        behavior.setPeekHeight(100);

    }

Click Event Code:

@Override
    public void onShareClick() {
        if (behavior.getState() == BottomSheetBehavior.STATE_EXPANDED) {
            behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
        }
        if(mBottomSheetDialog==null){
            mBottomSheetDialog = new BottomSheetDialog(this);
            View view = getLayoutInflater().inflate(R.layout.layout_bottomsheet, null);
            mBottomSheetDialog.setContentView(view);
        }

        mBottomSheetDialog.show();
        mBottomSheetDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
            @Override
            public void onDismiss(DialogInterface dialog) {
                mBottomSheetDialog = null;
            }
        });
    }

Replace

behavior.setPeekHeight(100);

with

behavior.setPeekHeight(screenUtils.getHeight());

will solve your problem.
