NestedScrollView剪切/覆盖嵌套片段的底部

Question

我有问题NestedScrollView,因为它削减了视图的底部.

我有FragmentA架构:

<RelativeLayout>
<android.support.design.widget.CoordinatorLayout>
    <android.support.design.widget.AppBarLayout>
        <android.support.design.widget.CollapsingToolbarLayout>
            <ImageView/>
            <android.support.v7.widget.Toolbar/>
        </android.support.design.widget.CollapsingToolbarLayout>
    </android.support.design.widget.AppBarLayout>
    <android.support.v4.widget.NestedScrollView>
        <LinearLayout>
            <FrameLayout> 
                <!-- fragment added dynamically-->
            </FrameLayout>
            <FrameLayout>
                <!-- fragment added dynamically-->
            </FrameLayout>
            <FrameLayout>
                <!-- fragment added dynamically-->
            </FrameLayout>
        </LinearLayout>
    </android.support.v4.widget.NestedScrollView>
    <android.support.design.widget.FloatingActionButton/>
</android.support.design.widget.CoordinatorLayout>

我正在为每个添加dinamically片段FrameLayout.

当我第一次运行应用程序时,我做了SS的样子:我第一次在屏幕上 为每个布局添加填充以查看发生了什么. green是CoordinatorLayout, red是NestedScrollView, orange在LinearLayout里面NestedScrollView.

现在我更换FragmentA用FragmentB,并再次复出FragmentA,我有这样的事情:错误dispaly

有人知道我做错了什么？

这是我的整个布局FragmentA:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

                android:focusableInTouchMode="true">

                android:id="@+id/frameForCalendar"
                android:minHeight="100dp"
                android:focusableInTouchMode="true">

            </FrameLayout>

            <FrameLayout

                android:id="@+id/frameForGraph"
                android:minHeight="100dp"
                android:focusableInTouchMode="true">
            </FrameLayout>

        </LinearLayout>

    </android.support.v4.widget.NestedScrollView>

    <android.support.design.widget.FloatingActionButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="@dimen/fab_margin"
        android:clickable="true"
        app:layout_anchor="@+id/appbar"
        app:layout_anchorGravity="bottom|right|end"
        app:backgroundTint="@color/colorAccent"
        android:id="@+id/floatingButtonLog" />

</android.support.design.widget.CoordinatorLayout>
</RelativeLayout>

编辑:我编译:

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.2.1'
compile 'com.android.support:support-v4:23.2.1'
compile 'com.android.support:design:23.2.1'
compile 'com.jjoe64:graphview:4.2.1'
}

我加入Fragments到FrameLayout用:

infoFragment = new InfoFragment();
    infoFragment.setLogs(mapLogIn, mapLogOut, monthToDispaly, yearToDispaly);
    infoFragment.setPracownik(mPracownik);


    if (getChildFragmentManager().findFragmentByTag("INFO") == null) {
        getChildFragmentManager()
                .beginTransaction()
                .add(R.id.frameForInfo, infoFragment, "INFO")
                .commit();
    }else {
        getChildFragmentManager()
                .beginTransaction()
                .replace(R.id.frameForInfo, infoFragment, "INFO")
                .commit();
    }

我如何更换FragmentA使用FragmentB:

((AppCompatActivity)getActivity()).getSupportFragmentManager()
                        .beginTransaction()
                        .replace(R.id.frameForFragment, edit)
                        .addToBackStack(null)
                        .commit();

怎么我回来从FragmentB到FragmentA:

getFragmentManager().beginTransaction().remove(AddingPerson.this).commit();

                    if (getFragmentManager().getBackStackEntryCount()>0){
                        getFragmentManager().popBackStack();
                    }

看起来NestedScrollView在底部是cuted,因为(如果你看ss)底部没有填充框架.

我注意到当我回来时FragmentA(当显示错误的显示时)我更换了NestedScrollView底部的片段NestedScrollView.

这是YT视频.

UPDATE

我在这里找到了临时答案.我补充说:

android:layout_gravity="fill_vertical"
android:layout_marginBottom="?attr/actionBarSize"

但有人写道,这个错误在v22.2.1中得到修复,但似乎并非如此.有人知道这件事吗？
