Android浮动按钮不正确

Question

我正在使用浮动按钮。我正在使用的图像源也是正确但不确定的同时设置它在中心显示为点。屏幕截图和代码如下：

if let detailVC = storyboard?.instantiateViewController(withIdentifier: "CardDetailVC") as? CardDetailViewController {
        detailVC.cardID = card.key
        navigationController?.pushViewController(detailVC, animated: true)
    }

Answer 1

尝试使用

<div>
   <span ng-repeat="image in post.postImages" ng-if="$index <= 3" ng-init="image.showDeleteIcon= false" ng-mouseover="image.showDeleteIcon=true" ng-mouseleave="image.showDeleteIcon=false">
   <span ng-if="$index == 3" ng-init="setImgCounter(post.postImages.length,$parent.$index+''+$index)"></span>
   <a id="{{$parent.$index}}{{$index}}" onclick="SetDataGallery(this.id)" ng-href="../upload/post-photos/{{image.attachmentURL}}">
   <img class="img-responsive feed-photo" ng-src="../upload/post-photos/{{image.attachmentURL}}" alt="Photo" style="display:inline;">
   <a href="#" class="imgDelete" ng-if="post.timelineStrore.hasControl" ng-show="image.showDeleteIcon" title="Delete Photo" ng-click="DeletePostAttachment(post.timelineStrore.id, image.postAttachmentId,'image')">
   <i class="fa fa-close"></i>
   </a>
   </a>
   </span>
</div>

fabSize可以调整为＆＃34; mini＆＃34; ＆安培; ＆＃34;正常＆＃34;

<android.support.design.widget.FloatingActionButton
  android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:src="@drawable/ic_done_white_24px"
 app:fabSize="mini"    
 android:scaleType="center"/>

试试这种工作正常，

<android.support.design.widget.FloatingActionButton
        android:id="@+id/fab_add_cg"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        app:elevation="10dp"

        app:borderWidth="0dp"
        app:backgroundTint="#f0f0"
        android:src="@android:drawable/ic_dialog_email"/>

将最新的支持库添加到您的app build gradle文件并构建您的项目

compile 'com.android.support:design:23.0.1'

}

<android.support.design.widget.FloatingActionButton
 android:id="id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:clickable="true"
