ScrollView无法在Android底表中滚动 [英] Scrollview not scrolling in Android bottomsheet

问题描述

我在Android支持中尝试了新的 BottomSheet .在 BottomSheet 内，我放置了 TextView 和 ScrollView . BottomSheet 显示得很好，我发现的唯一问题是 BottomSheet 中的 ScrollView 没有滚动.每次尝试滚动时，要么滚动主活动中的布局，要么 BottomSheet 将状态从折叠状态更改为展开状态.

I tried the new BottomSheet in Android support. Inside the BottomSheet I have put a TextView and a ScrollView. The BottomSheetshowing just fine, the only problem I found is that the ScrollView in the BottomSheet is not scrolling. Every time I try to scroll, either the layout in main activity that scroll or the BottomSheet changing state from collapse to expand.

这是我的活动分类代码的片段:

This is snippet of my Activity Class code:

private BottomSheetBehavior behavior;
View bottomSheet;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    setTextViewOnClickListener(this, findViewById(R.id.parentLayout));

    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.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
        @Override
        public void onStateChanged(@NonNull View bottomSheet, int newState) {
            // React to state change

        }


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

@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.tv1:
            setTextViewHeader("Header1");
            setTextViewContent("Long_Text_1");

            break;

        case R.id.tv2:
            setTextViewHeader("Header2");
            setTextViewContent("Long_Text_2");

            break;

        case R.id.tv3:
            setTextViewHeader("Header3");
            setTextViewContent("Long_Text_3");

            break;

        default:
            break;
    }

    behavior.setPeekHeight(100);
    behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
    behavior.setHideable(true);

    bottomSheet.requestLayout();
}

这是我的布局XML:

推荐答案

希望您现在已经知道了，但是将 View bottomSheet 更改为 NestedScrollView bottomSheet .

Hope you figured out this by now, but change View bottomSheet to NestedScrollView bottomSheet.
