Question

我有一项活动

public class ResourceListActivity extends AppCompatActivity {
    private ActivityResourceListBinding mBinding;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mBinding = DataBindingUtil.setContentView(this, R.layout.activity_resource_list);
        getWindow().setStatusBarColor(ContextCompat.getColor(getBaseContext(), R.color.colorPrimary));
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setElevation(0f);
        RecommendResourceFragment fragment = RecommendResourceFragment.newInstance(mColumnCount);
        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.container_main, fragment);
        fragmentTransaction.commit();
    }
}

布局文件如下：activity_resource_list.xml

    <layout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context="in.securelearning.lil.android.resources.view.activity.ResourceListActivity">

        <RelativeLayout
            android:id="@+id/container_main"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@color/colorWhite"
            app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

    </LinearLayout>
</layout>

和RecommendResourceFragment.java片段布局如下：

<layout>

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


        <android.support.design.widget.TabLayout
            android:id="@+id/tabLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:elevation="4dp"
            android:background="@color/colorPrimary"
            app:layout_collapseMode="parallax"
            app:tabGravity="fill"
            app:tabMode="scrollable"/>


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

</layout>

在下面的每个页面上，布局都是嵌入了水平标签的渲染。

<layout xmlns:app="http://schemas.android.com/apk/res-auto">

    <LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/colorBackground"
        android:orientation="vertical">

        <HorizontalScrollView
            android:id="@+id/hlistview"
            android:layout_width="match_parent"

            android:scrollbars="none">

            <LinearLayout
                android:id="@+id/imageview_holder"

        </HorizontalScrollView>

                    android:text="Hold on !\nLoading more videos..."
                    android:textSize="16sp"
                    android:visibility="gone"/>

            </LinearLayout>

            <ProgressBar
                android:id="@+id/progress_bar"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"/>

        </FrameLayout>

        <LinearLayout

    </LinearLayout>

</layout>

我已应用app：layout_behavior =＆＃34; @ string / appbar_scrolling_view_behavior＆＃34;在每个阶段，但工具栏没有隐藏。任何建议。提前谢谢。

Answer 1

尝试将此行添加到工具栏

  app:layout_scrollFlags="scroll|enterAlways|snap"

Answer 2

添加到工具栏

app:layout_scrollFlags="enterAlways"

CoordinatorLayout工具栏未隐藏在回收视图滚动上
