工具栏上的标题不会随着折叠的工具栏布局展开和折叠，它只是固定在抽屉导航按钮旁边。折叠作品我只需要标题通过工具栏的展开和折叠进行动画处理任何人都可以在这个问题上提供帮助

我尝试使用以下代码以编程方式设置标题，但无济于事。变量已通过 findViewById CollapsingToolBarLayout.setTitle("title);

绑定(bind)到布局

最佳答案

你的xml代码中有更多的 View ，我需要花时间来修改它们，而不是我会给你一个提示，所以尝试修改它。

xml代码

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout
    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"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".activity.NewsReaderActivity">


<androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavi"

/>

<com.google.android.material.appbar.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

    <com.google.android.material.appbar.CollapsingToolbarLayout
            android:id="@+id/collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="200dp"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:expandedTitleGravity="bottom"
            app:expandedTitleMarginEnd="@dimen/activity_horizontal_margin"
            app:expandedTitleMarginStart="@dimen/activity_horizontal_margin"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <ImageView
                android:id="@+id/toolbar_image"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:adjustViewBounds="true"
                android:contentDescription="@null"
                android:fitsSystemWindows="true"
                android:scaleType="centerCrop"
                android:src="@drawable/dabdamis" />

        <androidx.appcompat.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                app:layout_collapseMode="pin"
                app:popupTheme="@style/ThemeOverlay.AppCompat" />
    </com.google.android.material.appbar.CollapsingToolbarLayout>
</com.google.android.material.appbar.AppBarLayout>

将其放入您的 onCreate 方法

setSupportActionBar(toolbar)

也可以使用下面的代码作为工具栏的标题

    //set title of the  toolbar
    collapsing_toolbar.setTitle= "Your Title"

collapsing_toolbar 是我的 CollapsinToolbar 的 ID，因此使用 findViewById

关于java - 折叠工具栏问题标题停留在屏幕顶部并且不折叠 Android，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56996539/
