java – 底部表Android的滚动问题

我需要将底页停在两个位置.我有底部表格的以下代码.

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        ....
    </RelativeLayout>

    <FrameLayout
        android:id="@+id/bottom_sheet"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
           <ScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent">

                <LinearLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:background="@color/white"
                    android:minHeight="1000dp"
                    android:orientation="vertical">
                    ....
                </LinearLayout>
          </ScrollView>
     </FrameLayout>
</android.support.design.widget.CoordinatorLayout>

和

View bottomSheet = coordinatorLayout.findViewById(R.id.bottom_sheet);
        final BottomSheetBehavior behavior = BottomSheetBehavior.from(bottomSheet);
        behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
            @Override
            public void onStateChanged(@NonNull View bottomSheet, int newState) {
                // React to state change
                Log.e("onStateChanged", "onStateChanged:" + newState);
                if (newState == BottomSheetBehavior.STATE_EXPANDED) {
                    behavior.setPeekHeight(600);
                    showAgain.setVisibility(View.GONE);
                    mMap.getUiSettings().setScrollGesturesEnabled(false);
                } else if (newState == BottomSheetBehavior.STATE_COLLAPSED) {

                    if (behavior.getPeekHeight() == 600) {
                        behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
                        behavior.setPeekHeight(80);
                        mMap.getUiSettings().setScrollGesturesEnabled(false);
                    } else if (behavior.getPeekHeight() == 80) {
                        showAgain.setVisibility(View.VISIBLE);
                        mMap.getUiSettings().setScrollGesturesEnabled(true);
                    }

                }
            }

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

        behavior.setPeekHeight(600);

除了一件事,此代码工作正常.我第一次向上滚动底部页面然后我可以向下滚动它.我不能直接向下滚动表格.

任何帮助将不胜感激.

解决方法:

我不知道这是否可以解决您的问题,但我通过使用NestedScrollView替换BottomSheet中的ScrollView来修复BottomSheet中的相当多的滚动问题.
