"Android" defines drawable arrays, id arrays, and so on in an XML file

If we need to set up a set of picture resources for a set of view settings in code, such as setting a corresponding set of images for all of Listview/gridview's item, we can define a set of drawable arrays representing the pictures in the XML and then read them in code.

At first I was doing this:

<integer-array name= "Actions_images" >    <item> @drawable/pencil1</item>    <item>@ drawable/pencil2</item>    <item> @drawable/pencil3</item>    <item> @drawable/pencil4 </item>    <item> @drawable/pencil5</item>    <item> @drawable/pencil6</item> </integer-array>

And then in the code,tried toCall Getresources (). Getintarray to get the ID of the image, you can see that it doesn't work. Finally, StackOverflow gives the solution:

1, in the XML to define this:

<string-array name= "Actions_images" >    <item> @drawable/pencil1</item>    <item>@ drawable/pencil2</item>    <item> @drawable/pencil3</item>    <item> @drawable/pencil4 </item>    <item> @drawable/pencil5</item>    <item> @drawable/pencil6</item> </string-array>

2, in the Java code in this way to get:

TypedArray ar = context.getresources (). Obtaintypedarray (r.array.actions_images); int len = Ar.length ();     int[] Resids = new Int[len];     for (int i = 0; i < len; i++)         resids[i] = Ar.getresourceid (i, 0); Ar.recycle ();  

The ID of the picture is saved in the Resids, and then we can refer to it (for example, with Img.setimageresourse (resids[0)) to set the picture.

Similarly, it is the same thing to define an array of IDs in XML.
