如何锁定底层到他的窥视高度？

Question

I am using this library:

compile 'com.android.support:design:23.2.0'

And i did this bottom sheet but after some actions i want to lock it on the bottom of the screen only with 1 raw visible. This is the tutorial where I am looking from. I want to lock the bottom sheet like the 3rd item from the tutorial.

If you have any ideas will be great :)

Here is my code:

private void initBottomSheet() {
        mBottomSheetBehavior = BottomSheetBehavior.from(bottomSheet);
        mBottomSheetBehavior.setPeekHeight(200);
        mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
        mBottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
            @Override
            public void onStateChanged(View bottomSheet, int newState) {
                if (newState == BottomSheetBehavior.STATE_COLLAPSED) {
                    mBottomSheetBehavior.setPeekHeight(200);
                }
            }

            @Override
            public void onSlide(View bottomSheet, float slideOffset) {
            }
        });
    }

我认为您忘记使用此代码： mBottomSheetBehavior.setPeekHeight(300);
