Create View-Object from XML file in android

阅读更多关于 Create View-Object from XML file in android

问题 I only want to get an object from a xml layout file without having to implement it into the current layout. I know the way with LayoutInflater.from(context).inflate(R.layout.myfile, myparent, true); but after execution of the above the layout will be implemented and shown immediately inside my "myparent"-View, right? I only want to get the Object itself to get its attributes and such. And maybe (but only maybe) insert it later into the shown layout. Is that possible? Regards 回答1: You should

Populate ListFragments with a custom view?

阅读更多关于 Populate ListFragments with a custom view?

previously, I had no problem with inflating a layout as a custom view hierarchy for a ListView. But I have no clue on how to do the same for a listFragment. Lets say I have an item_list layout with an ImageView and 2 textviews in it. I want to inflate this to be used in my ListFragment. But how?? public class Tab1Fragment extends ListFragment { private LayoutInflater mInflater; private Vector<RowData> data; RowData rd; static final String[] title = new String[] { "Classic Plank", "Side Plank", "Reversed Plank", "Swissball Plank", "One Arm One Leg", //5 }; static final String[] description =

Android: setContentView() == getViewInflate().inflate()?

阅读更多关于 Android: setContentView() == getViewInflate().inflate()?

问题 I try my hardest to develop a clever way to clean out piles of Blah blah = (Blah) this.findViewById(R.id.blah) that otherwise pollute the field and the onCreate() method of my little Activity, and to do so, I feel I should not use setContentView() but getViewInflate().inflate() for every View defined in XMLs. Is Activity.setContentView() is sorta a syntax sugar and it's virtually repeating getViewInflate().inflate() for every View on XML? I read something saying as if they were the same. If I

What is the difference between calling LayoutInflater directly and not?

阅读更多关于 What is the difference between calling LayoutInflater directly and not?

问题 I went through some tutorials, and in the Android Doc, it says not to access LayoutInflater directly when instantiating it. Example from the google Doc: LayoutInflater inflater = (LayoutInflater)context.getSystemService (Context.LAYOUT_INFLATER_SERVICE); The tutorial I went through is this one: LayoutInflater inflater = LayoutInflater.from(parent.getContext()); So what I don't really understand is what the difference is besides the obvious different code. Any explanation much appreciated. I

How to use LayoutInflater / ViewStub for an overlay

阅读更多关于 How to use LayoutInflater / ViewStub for an overlay

As I am actually not very confident with programatically changing Views, I have following problem: At the first start of my app, I want to have an overlay for the main screen, that tells the user to have a look at the settings, as there are two critical options the user has to configure. I don't want to use an AlertDialog and rather not use a wizard. So, I decided to take an approach similar to Go SMS and create an overlay at the first start. The mockup I created looks like this: Normal menu: First start: So these are the problems I have: Like I said, I don't want to use a screenshot
