我正在尝试在滚动内容时隐藏/显示我的工具栏,当我将其注入到FrameLayout容器中并且不起作用时,这是我的应用栏布局:

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

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/tool_bar_bg"
        app:elevation="0dp"
        android:theme="@style/AppTheme.AppBarOverlay"
        android:fitsSystemWindows="true"
        android:id="@+id/app_bar_layout">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_marginStart="10dp"
            android:layout_marginEnd="10dp"
            android:layout_marginTop="5dp"
            android:layout_marginBottom="5dp"
            android:layout_width="match_parent"
            android:layout_height="50dp"
            app:layout_scrollFlags="scroll|enterAlways"
            android:background="@drawable/bg_actionbar"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

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



        <!-- My scrolling content -->
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>



    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        app:srcCompat="@android:drawable/ic_dialog_email" />

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

和我的SecondActivity布局

   <android.support.v4.widget.NestedScrollView xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:fillViewport="true"
        android:gravity="center"
        android:paddingLeft="20dp"
        android:paddingRight="20dp">

        <TextView
            android:id="@+id/textone"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:text="@string/content"
            android:textSize="25dp" />


    </LinearLayout>

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

这是我的Java代码,它可以简化活动布局:

    public class FirstActivity extends BaseActivity {   
       @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            //inflate your activity layout here!
            @SuppressLint("InflateParams")
            View contentView = inflater.inflate(R.layout.activity_user, null, false);
            drawer.addView(contentView, 0);
}

当我滚动它不起作用时,我也用RelativeLayout,LinearLayout签入SecondActivity,但是它没有隐藏。

布局充气机的问题我已经更改了布局充气机:

FrameLayout container = (FrameLayout) findViewById(R.id.content_frame);
        View inflatedLayout= getLayoutInflater().inflate(R.layout.activity_user, null, false);
        container.addView(inflatedLayout);

请使用android.support.design.widget.CollapsingToolbarLayout

包围要在滚动过程中隐藏/显示的项目
