访问&LT;申报,设置样式&GT;资源编程 [英] Accessing <declare-styleable> resources programatically
本文介绍了访问&LT;申报,设置样式&GT;资源编程的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个问题,我找不到任何帮助:
I've one question where I couldn't find any help:
是否有可能,以获得资源-IDS中保留了一个为int []编程,而不指的是资源型R级?
Is it possible, to receive the resource-ids being kept by a as an int[] programatically without refering to the resource-class R ?
<declare-styleable name="com_facebook_login_view">
<attr name="confirm_logout" format="boolean"/>
<attr name="fetch_user_info" format="boolean"/>
<attr name="login_text" format="string"/>
<attr name="logout_text" format="string"/>
</declare-styleable>
现在的问题是,我不能化解定义的申报,设置样式'属性的ID - 为0x00总是返回:
The problem is that I cannot resolve the ID of the defined 'declare-styleable' attribute - 0x00 is always returned:
int id = context.getResources().getIdentifier( "com_facebook_login_view", "declare-styleable", context.getPackageName() );
int[] resourceIDs = context.getResources().getIntArray( id );
任何想法会大大AP preciated! :)
Any idea would be greatly appreciated! :)

推荐答案
下面是提供的资源标识编程为孩子解决方案 - 为标签定义的标记:
Here is the solution that delivers the resource-IDs programatically for the child--tags defined for a tag:
/*********************************************************************************
* Returns the resource-IDs for all attributes specified in the
* given <declare-styleable>-resource tag as an int array.
*
* @param context The current application context.
* @param name The name of the <declare-styleable>-resource-tag to pick.
* @return All resource-IDs of the child-attributes for the given
* <declare-styleable>-resource or <code>null</code> if
* this tag could not be found or an error occured.
*********************************************************************************/
public static final int[] getResourceDeclareStyleableIntArray( Context context, String name )
{
try
{
//use reflection to access the resource class
Field[] fields2 = Class.forName( context.getPackageName() + ".R$styleable" ).getFields();
//browse all fields
for ( Field f : fields2 )
{
//pick matching field
if ( f.getName().equals( name ) )
{
//return as int array
int[] ret = (int[])f.get( null );
return ret;
}
}
}
catch ( Throwable t )
{
}
return null;
}
也许这可以帮助别人一天。 :)
Maybe this could help somebody one day. :)
