layout-inflater

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 can get an answer by looking into the code, please tell so. I checked Activity.class, but only

I'm trying to do something I do with activities, but within a fragment. What I do is using activities: First stop the activity restarts when rotating the device android:configChanges="keyboardHidden|orientation|screenSize" in my activity add: @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); setContentView(R.layout.main); } So get the activity does not restart, but reloading the main.xml, to use the layout-land Now I have an activity showing viewpager, which contains three fragments. Everything works properly. Detection of the

I have an ImageView that I attach to a MenuItem as its ActionView (the item appears in the ActionBar ). The layout for this view comes from XML. I'm inflating it like so: ImageView actionView = (ImageView) layoutInflater.inflate( R.layout.action_view_layout, null); This appears to work fine. However; passing null for root in the call to inflate() makes Lint yell at me: Avoid passing null as the view root (need to resolve layout parameters on the inflated layout's root element) I can seemingly manage without a root in my specific case, but I'd rather have the code be as correct as possible. The

There is a way to get layoutInflater: LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); and another way is: LayoutInflater inflater = LayoutInflater.from(context); a third one (when I am in an Activity) is: LayoutInflater inflater = getLayoutInflater(); So what is the difference between them? Note that when I sent the third inflater to my adapter, my application worked. But when I sent the context and created the inflater via the second way, it didn't! There is not much of a difference between them. As doc says public abstract Object

When Android inflates a Button with an onClick XML attribute, it internally sets a DeclaredOnClickListener on that Button which then uses reflection to trigger the actually onClick method in our code. case R.styleable.View_onClick: [...] final String handlerName = a.getString(attr); if (handlerName != null) { setOnClickListener(new DeclaredOnClickListener(this, handlerName)); } break; I noticed that for AppCompatButton s (i.e. normal Buttons in an AppCompatActivity ) the same process gets repeated in the AppCompatViewInflater class, resulting in 2 different DeclaredOnClickListener s set in

I want to have a sliding menu throughout my application which will be accessible for every activity in my application. For this, I created a parent activity to which all other activities extend as suggested in this answer . So that, only one activity will implement that sliding menu functionality and all other activities extending that activity will have that implementation. But my problem is, when I press UP button (app icon) the sliding drawer should show up and the whole layout should shift to the right side. This works fine for the BaseActivity, but for the activities extending that class,
