标签: android drawable floating-action-button

在我的应用程序中,我使用com.android.support:design:25.0.0来获取FloatingActionButton,但是当我为它设置Icon时

app:fab_icon="@drawable/ic_done"

我收到错误

Cannot Resolve symbol @drawable/ic_done

我尝试了其他图标,但没有一个正在运作?

XML:

<?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_cust"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="end|bottom"
        android:layout_margin="16dp"
        />

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab_nxt"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="end|bottom"
        android:layout_margin="16dp"
        app:fab_icon="@drawable/ic_done"
        />

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

Gradle Dependecies:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:support-v4:24.2.1'
    compile 'com.android.support:design:24.2.1'
    compile 'com.getbase:floatingactionbutton:1.10.1'
    testCompile 'junit:junit:4.12'
}

修改

我也尝试用android:src替换fab_icon,但没有一个工作。 enter image description here

尝试添加src而不是图标。请遵守代码。

android:src="@android:drawable/ic_done"
