使用“动画圈"在加载内容时在 ImageView 中 [英] Using the "animated circle" in an ImageView while loading stuff

问题描述

我目前在我的应用程序中使用可能需要一秒钟才能显示的列表视图.

I am currently using in my application a listview that need maybe one second to be displayed.

我目前所做的是使用列表视图的@id/android:empty 属性来创建加载"文本.

What I currently do is using the @id/android:empty property of the listview to create a "loading" text.

 <TextView android:id="@id/android:empty"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:background="#FF0000"
           android:text="Loading..."/>

现在，我想用加载对话框中使用的动画圆圈代替这段文字，我想你们都知道我的意思:

Now, I would like to replace that with the animated circle that is used in a loading dialog instead of this text, i guess you all know what I mean:

我不想要对话.我想在我的布局中展示它.

I do not want a dialog. I want to show that inside my layout.

非常感谢您的帮助！

推荐答案

只需将此块 xml 放入您的活动布局文件中即可:

Simply put this block of xml in your activity layout file:

<RelativeLayout
    android:id="@+id/loadingPanel"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center" >

    <ProgressBar
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:indeterminate="true" />
</RelativeLayout>

当你完成加载时，调用这一行:

And when you finish loading, call this one line:

findViewById(R.id.loadingPanel).setVisibility(View.GONE);

结果(它也会旋转):
