在Android中引用其他程序的文本资源并不是很常见,但是有时候还是很是有需要的,通常引用的多半是系统的程序的文本资源.
下面以一个超简单的例子,来展示以下如何实现.
Context context = getContext();
Resources res = null;
try {
//I want to use the clear_activities string in Package com.android.settings
res = context.getPackageManager().getResourcesForApplication("com.android.settings");
int resourceId = res.getIdentifier("com.android.settings:string/clear_activities", null, null);
if(0 != resourceId) {
CharSequence s = context.getPackageManager().getText("com.android.settings", resourceId, null);
Log.i(VIEW_LOG_TAG, "resource=" + s);
}
} catch (NameNotFoundException e) {
e.printStackTrace();
}
}
