在 Android Studio 上原始使用参数化 class

Question

我的 Android 项目中有此代码：

final BottomSheetBehavior infoBottomSheetBehavior = BottomSheetBehavior.from(findViewById(R.id.info_view));
        infoBottomSheetBehavior.addBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
            @Override
            public void onStateChanged(@NonNull View bottomSheet, int newState) {
                if (newState == BottomSheetBehavior.STATE_DRAGGING) {
                    infoBottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
                }
            }
            @Override
            public void onSlide(@NonNull View bottomSheet, float slideOffset) {
            }
        });

下一个警告出现在 BottomSheetBehavior 上：Raw use of parameterized class 'BottomSheetBehavior'

有人知道如何避免这个警告吗？

好的，这是咖啡谈话的基本答案...

final BottomSheetBehavior<View> infoBottomSheetBehavior = BottomSheetBehavior.from(findViewById(R.id.info_view));
        infoBottomSheetBehavior.addBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
            @Override
            public void onStateChanged(@NonNull View bottomSheet, int newState) {
                if (newState == BottomSheetBehavior.STATE_DRAGGING) {
                    infoBottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
                }
            }
            @Override
            public void onSlide(@NonNull View bottomSheet, float slideOffset) {
            }
        });

我刚刚错过了 <View>

在 Android Studio 上原始使用参数化 class

Raw use of parameterized class on Android Studio

android

parameterized-class

bottom-sheet
