Question

所以我在布局时出现了错误，这是关于NoSuchMethodException的。我已经看过其他解决方案了，我已经确定我已经完成了以下操作，我已经完成了这个例外。有谁知道这可能导致什么？我完全迷失了，一切正常，然后我更新了我的android工作室，现在我收到了这个错误。

我的活动是AppCompatActivity

我的应用布局，使用AppCompat：

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowNoTitle">true</item>
</style>

我的布局代码，使用app命名空间设置背景色调：

<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"
    android:src="@drawable/ic_add_white_18dp"
    app:backgroundTint="@color/colorPrimary"
    app:layout_behavior="Behaviors.ScrollAwareFABBehavior"/>

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

这是我的gradle构建文件：

compile 'com.android.support:multidex:1.0.0'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.android.support:support-v4:23.4.0'
compile 'com.android.support:recyclerview-v7:23.4.0'
compile 'com.android.support:cardview-v7:23.4.0'
compile 'com.google.android.gms:play-services:9.4.0'

这是我的堆栈跟踪：

Answer 1

我确实遇到了一些问题，它是随机的，今天是在Android工作室选择“确定”关于下载内容相关的东西之后。：P

我尝试升级SDK构建工具（不使用它们），并重建项目但没有运气。

然后，我升级到JAVA 1.8，转移到compileSdkVersion 24并支持库24.2.1并且它有效。

因此，谷歌有可能在上次更新时破坏了某些内容。

Answer 2

将compileSdkVersion设置为24，然后更改

compile＆＃39; com.android.support：design：23.4.0＆＃39;

到

compile＆＃39; com.android.support：design：24.2.0＆＃39;

然后同步您的项目，它将解决问题。

Answer 3

当我运行应用程序时！我得到了更多细节错误！

Caused by: java.lang.NoSuchMethodError: No direct method <init>(Landroid/widget/ImageView;Landroid/support/v7/widget/AppCompatDrawableManager;)V in class Landroid/support/v7/widget/AppCompatImageHelper; or its super classes (declaration of 'android.support.v7.widget.AppCompatImageHelper' appears in /data/data/com.weituotian.weituotianvideo/files/instant-run/dex/slice-com.android.support-appcompat-v7-25.0.0_850df7fcd98a57a963b231f15b37dc8c4ae3ee97-classes.dex)

所以请使用appcompatv7：25
