将imageview添加到collapsingtoolbarlayout Android时出错

Question

我想将图片放在我的应用栏布局上，如下所示

我已经在mipmap中使用了我的图像但是在向AppbarLayout添加ImageView时遇到了问题

这是我的代码：

    <?xml version="1.0" encoding="utf-8"?>
<android.support.design.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="com.example.android.imgedit.MainPage">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/app_bar"
        android:layout_width="match_parent"
        android:layout_height="@dimen/app_bar_height"
        android:fitsSystemWindows="true"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/toolbar_layout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|exitUntilCollapsed"
            app:toolbarId="@+id/toolbar"
            app:statusBarScrim="@null">

            <ImageView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:fitsSystemWindows="true"
                android:scaleType="centerCrop"
                app:layout_collapseMode="parallax"
                android:src="@mipmap/appbarimage"/>
            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                app:layout_collapseMode="pin"
                app:popupTheme="@style/AppTheme.PopupOverlay" />

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


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

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

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

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

然而，之后我遇到了一个错误：

有人知道这个的原因吗？

如果我删除了ImageView组件，一切正常

Answer 1

将您的图像文件放在可绘制文件中，并将代码更改为：

android:src="@drawable/appbarimage"

我认为它会起作用。

Answer 2

错误说：

确保ImageView没有正确充气。

确保将您的appbarimage复制到drawable文件夹中并更改

Caused by: android.content.res.Resources$NotFoundException: Resource "com.example.android.imgedit:mipmap/appbarimage" (7f0c0000)  is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f0c0000 a=-1 r=0x7f0c0000}

到

android:src="@mipmap/appbarimage"

Answer 3

我有一个类似的问题。只需确保图像位于android：src =“ @ drawable / appbarimage”
