您好，我从布局编辑器中收到此渲染错误。

这是布局:

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">

<data>

    <variable
        name="categoryHandler"
        type="ci.ali.moneymaker.handlers.CategoryHandler" />
</data>

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    <!-- our tablayout to display tabs  -->
    <android.support.design.widget.TabLayout
        android:id="@+id/tabLayout"
        style="@style/AppTabLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabMode="fixed" />

    <!-- View pager to swipe views -->
    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/tabLayout"
        android:background="@color/background_grey"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab_add_account"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentEnd="true"
        android:layout_margin="@dimen/fab_margin"
        android:onClick="@{categoryHandler::addCategory}"
        android:src="@drawable/ic_fab_add"
        app:backgroundTint="@color/colorPrimaryLight"
        app:elevation="2dp"
        app:rippleColor="#99FFFFFF" />

</RelativeLayout>
</layout>

到目前为止我尝试过的:1.同版本grandle依赖

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:25.2.0'
compile 'com.android.support:design:25.2.0'
compile 'com.android.support:recyclerview-v7:25.2.0'
compile 'com.android.support:support-v4:25.2.0'
compile 'com.android.support:cardview-v7:25.2.0'
compile 'com.android.support:support-v4:25.2.0'
compile 'com.android.support:support-v13:25.2.0'
compile 'com.jakewharton.threetenabp:threetenabp:1.0.4'
compile 'net.objecthunter:exp4j:0.4.7'
compile 'com.github.PhilJay:MPAndroidChart:v3.0.1'
}

1. 从 FAB 中删除了 backgroundTint。
2. 更改了依赖版本。
3. 使缓存失效/重启
4. 重新创建 FAB
5. 创建了一个新项目并将 FAB 添加到新布局中。一切正常。

到目前为止没有任何效果。希望你能帮我解决这个错误。

如果我打开 FloatingActionButton.java 类，会出现一些导入错误，如屏幕截图所示。

也许这是导致错误的原因。但是我还是不知道怎么解决。

Answer 1

终于自己解决了。我不得不换行

<declare-styleable name="FloatingActionButton">

到

<declare-styleable name="CustomFloatingActionButton">

现在一切正常。
