在Android中输入类android.support.design.widget.FloatingActionButton时出错

时间：2016-10-07 12:05:04

标签： android android-layout floating-action-button android-api-levels

当我尝试构建应用程序时，它将在FloatingActionButton中显示"@cycle/dom": "^12.2.5" "@cycle/http": "^11.0.1" "@cycle/xstream-run": "^3.1.0" "xstream": "^6.4.0" ？我真的不知道导致错误的原因。

在你的案例中，问题在你的styles.xml中，你的基本主题名是AppBaseTheme。将其更改为AppTheme，因为您可以看到您在Mainfest文件中使用了AppTheme。

我列出了可能导致类android.support.design.widget.FloatingActionButton的所有原因。请仔细阅读要点。

  1. FAB按钮是Design Library Cpmponent。您的活动必须扩展 AppCompatActivity ，而不是活动。

  2. 您的活动主题也应该是适当的 Theme.AppCompat 主题。 FAB也需要colorAccent。确保在styles.xml中包含它们。

    <!-- Base application theme. -->
<style name="AppTheme" parent="Base.AppTheme">
<!-- Customize your theme here. -->
</style>

<style name="Base.AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:colorPrimary">@color/primary</item>
<item name="android:colorPrimaryDark">@color/primary_dark</item>
<item name="android:colorAccent">@color/accent</item>
</style>

  3. 使用 app：backgroundTint =“@ color / your_color”而不是android：backgroundTint。

  4. 不要错过在项目build.gradle文件中添加设计库

    dependencies {
 compile 'com.android.support:appcompat-v7:23.1.1'
 compile 'com.android.support:design:23.1.1'
 ...
}

  5. 在Extras中更新SDK Manager上的支持库＆gt; Android支持存储库和Android支持库

    6. 希望它能解决你的错误。

如果您在API 21+上使用backgroundTint，那么 只需在FloatingActionButton中使用此行（app而不是android）：

app:backgroundTint="@color/colorAccent"

以下是示例布局

<?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"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <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"
        app:elevation="6dp"
        android:tint="#FFF"
        app:srcCompat="@drawable/ic_add_black_24dp" />

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