Question

我在我的应用程序中实现了折叠工具栏，它应该没问题但是栏不受限制..不动也没有任何作用!!!

这是我的layout.xml

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/coordinatorLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">
    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="192dp"
        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:expandedTitleMarginBottom="32dp"
            app:expandedTitleMarginEnd="64dp"
            app:expandedTitleMarginStart="48dp"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">
            <ImageView
                android:id="@+id/header"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="@drawable/background"
                android:fitsSystemWindows="true"
                android:scaleType="centerCrop"
                app:layout_collapseMode="parallax" />
            <android.support.v7.widget.Toolbar
                android:id="@+id/anim_toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                app:layout_collapseMode="pin"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
        </android.support.design.widget.CollapsingToolbarLayout>
    </android.support.design.widget.AppBarLayout>
    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="@dimen/fab_button_margin_right"
        android:clickable="true"
        android:src="@drawable/fab_ic_add"
        app:layout_anchor="@+id/appbar"
        app:layout_anchorGravity="bottom|right|end" />
</android.support.design.widget.CoordinatorLayout>

这是我的活动

    public class Profile extends AppCompatActivity implements View.OnClickListener{
    private Toolbar toolbar;
    private CollapsingToolbarLayout collapsingToolbar;
    int mutedColor = R.attr.colorPrimary;
    FloatingActionButton fab;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.profile);

        final Toolbar toolbar = (Toolbar) findViewById(R.id.anim_toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        collapsingToolbar = (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
        collapsingToolbar.setTitle("Hello!");

        ImageView header = (ImageView) findViewById(R.id.header);

        Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
                R.drawable.background);
        fab = (FloatingActionButton) findViewById(R.id.fab);
        if(fab != null)
            fab.setOnClickListener(this);
        Palette.from(bitmap).generate(new Palette.PaletteAsyncListener() {
            @Override
            public void onGenerated(Palette palette) {

                mutedColor = palette.getMutedColor(R.attr.colorPrimary);
                collapsingToolbar.setContentScrimColor(mutedColor);
            }
        });

    }

}

请告诉我原因，提前谢谢！

更新我已经用NestedScrollView解决了这个问题，我这样做了：

选中它对我有用，你也可以在工具栏下的AppBarLayout中添加任何视图，用工具栏上下动画

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

<android.support.design.widget.AppBarLayout
    android:id="@+id/appBarLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

  </android.support.design.widget.AppBarLayout>

    <android.support.v4.view.ViewPager
        android:id="@+id/tabanim_viewpager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />



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

您可以将ViewPager更改为任何视图，只需添加其行为。如果您想以编程方式为其设置动画，还可以检查Bartosz Lipinski的答案 link
