我在片段中使用FAB按钮和RecyclerView.此Fragment是TabViewPager的一个实例.我遇到了FAB按钮的问题.我已将RecyclerView和fab按钮放在FrameLayout内,其中FAB按钮位于右下方.现在我遇到的问题是FAB按钮不完全可见.它的一半部分是隐藏的,如下面的屏幕截图所示.任何人都可以帮我解决这个问题.提前致谢.

注意: FAB滚动后正确对齐.只有在理想的情况下(滚动完成之前)才会出现问题.

我有一个简单的应用程序与viewpager包含3个片段.在其中一个片段中我有Recyclerview列表.向下滚动时,工具栏将折叠,并显示向上滚动时.我的问题是当工具栏折叠并且我向左/向右滚动时我会以编程方式展开它并且它会将viewpager向下推,而不是仅仅重叠它.这导致屏幕视图的不令人愉快的位移.如何让工具栏与我的viewpager重叠,而不是在展开时将其向下推?我对问题点击进行了简短记录

我有CoordinatorLayout一个Toolbar和TabLayout里面的AppBarLayout.另外,我有一个ViewPager在里面,CoordinatorLayout但在外面ViewPager.
问题是ViewPager's高度大于实际可用的高度,导致我Fragment被切割的一些视图.

当我将应用程序加载到手机或使用模拟器时,我的ListView底部和ImageButton被切断了.我可以使用边距或填充,但这不是特定于设备?无论屏幕大小如何,我都希望我的应用看起来像我想要的那样.这是我的代码:
班级:
public class Cookbook extends Fragment {
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
String[] items = {"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity().getApplicationContext(),
R.layout.row_layout,
items);
View view = inflater.inflate(R.layout.frag_cookbook, container, false);
ListView list = (ListView) view.findViewById(R.id.listView);
list.setAdapter(adapter);
return view;
