问题描述
我想按照下面的教程来加载一些图片在我的应用程序:
I am trying to load some images in my app according to the following tutorial:
的http://www.anddev.org/novice-tutorials-f8/imageview-with-loading-spinner-t49439.html
我的问题是,我想有相同的XML文件,我所有的课程,只是改变负载图像的URL。
My problem is that I would like to have the same XML file for all my classes and just change the URL of the load image.
我用这个code在我的的.java
文件:
I'm using this code in my .java
file:
final LoaderImageView image = new LoaderImageView(this,
"http://kostas-menu.gr/chania/santrivani.jpg");
image.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
这在我的xml:
And this in my xml:
<com.example.android.LoaderImageView
android:layout_marginTop="10px"
android:id="@+id/loaderImageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
image="http://developer.android.com/images/dialog_buttons.png"
/>
我想删除行图像=http://developer.android.com/images/dialog_buttons.png
,但如果我这样做,我没有得到任何图像。
I would like to erase the line image="http://developer.android.com/images/dialog_buttons.png"
but if I do it I'm not getting any image.
我怎么能调用一个单独的图像从我的班?
How could I call a separate image from my class?
推荐答案
我会简单地使用的ImageView
您的布局(这可能有一个虚拟画面),然后使用Java来替换图片:链接
I would simply use an ImageView
on your Layout (which maybe has a dummy-picture) and then use Java to replace the Image: Link
