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):
