CoordinatorLayout工具欄不隱藏在回收視圖滾動

Question

我有一個活動

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(); 
    } 
} 

佈局文件是：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> 

而且RecommendResourceFragment.java片段編排如下：

<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> 

而在每個頁面下面的佈局是嵌入水平標籤呈現。

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

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

       android:layout_gravity="bottom|center" 
       android:gravity="center_horizontal" 
       android:orientation="vertical" 
       android:visibility="gone"> 

       <ProgressBar

        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"

     </FrameLayout> 

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

      android:layout_height="match_parent"

      android:orientation="vertical" 
      android:visibility="gone"> 

      <ImageView 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:src="@drawable/logo_assignment" /> 

      <in.securelearning.lil.android.base.widget.TextViewCustom

       android:text="@string/string_no_results_found" 
       android:textSize="20sp" /> 

     </LinearLayout> 

    </LinearLayout> 

</layout> 

我已經申請程序：layout_behavior = 「@字符串/ appbar_scrolling_view_behavior」 在每一個階段，但工具欄不隱藏。 任何建議。提前致謝。

Answer 1

嘗試將此行添加到工具欄

app:layout_scrollFlags="scroll|enterAlways|snap" 

Answer 2

附加

app:layout_scrollFlags="enterAlways"
