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,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.
@H_502_21@解决方法
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：
