Question

我在CollapsingToolbarLayout中有recyclelerview，我希望它可以滚动，但事实并非如此。当我滚动时，appbar滚动但不是recyclelerview。我尝试了不同的东西，但它不起作用。这是我的代码：

<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/caves_content"
    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="@dimen/app_bar_height"
        android:theme="@style/AppTheme.AppBarOverlay"
        android:fitsSystemWindows="true">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapse"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            app:layout_scrollFlags="scroll"
            android:nestedScrollingEnabled="true"
            app:titleEnabled="false">

            <ImageView
                android:id="@+id/caves_backdrop"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:fitsSystemWindows="true"
                android:background="@mipmap/mount"
                android:adjustViewBounds="true"
                android:scaleType="centerCrop" />



            <android.support.v7.widget.RecyclerView
                android:id="@+id/recycler"
                android:layout_width="match_parent"
                android:layout_height="200dp"/>

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                app:theme="@style/WhiteToolbarStyle"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                app:layout_collapseMode="none" />

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

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

    <android.support.v4.widget.NestedScrollView
        android:id="@+id/nested"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <include layout="@layout/content"/>

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

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

Answer 1

我找到了解决方案：

GL11.glPushMatrix();
float rotateAxis = 1.0f;
float stableAxis = 0.0f;

int degreesPitch = (1+random.nextInt(4))*90;
int degreesRoll = (1+random.nextInt(4))*90;
int degreesYaw = (1+random.nextInt(4))*90;

GL11.glRotate(degreesRoll , stableAxis ,stableAxis ,rotateAxis );
GL11.glRotate(degreesYaw , stableAxis ,rotateAxis ,stableAxis );
GL11.glRotate(degreesPitch ,rotateAxis ,stableAxis ,stableAxis );
//Your tessellator code
tessellator.draw();
GL11.glPopMatrix();

Answer 2

在Appbarlayout中将“水平轨道”设置为false

此问题已解决。让我知道它是否不起作用

代码

<com.google.android.material.appbar.CollapsingToolbarLayout
    android:id="@+id/toolbar_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    app:contentScrim="#fff"
    app:layout_scrollFlags="scroll|exitUntilCollapsed"
    app:toolbarId="@+id/toolbar2"
    android:scrollbarAlwaysDrawHorizontalTrack="false"
    app:expandedTitleMarginEnd="64dp"
    app:expandedTitleMarginStart="48dp"
    app:expandedTitleTextAppearance="@style/TransparentText">
