LayoutInflater

LayoutInflater

 protected LayoutInflater (Context context)

Create a new LayoutInflater instance associated with a particular Context. Applications will almost always want to use Context.getSystemService() to retrieve the standard Context.INFLATER_SERVICE.

LayoutInflater

 protected LayoutInflater (LayoutInflater original,                  Context newContext)

Create a new LayoutInflater instance that is a copy of an existing LayoutInflater, optionally with its Context changed. For use in implementing cloneInContext(Context).

cloneInContext

 public abstract LayoutInflater cloneInContext (Context newContext)

Create a copy of the existing LayoutInflater object, with the copy pointing to a different Context than the original. This is used by ContextThemeWrapper to create a new LayoutInflater to go along with the new Context theme.

createView

 public final View createView (Context viewContext,                  String name,                  String prefix,                  AttributeSet attrs)

Low-level function for instantiating a view by name. This attempts to instantiate a view class of the given name found in this LayoutInflater's ClassLoader.

There are two things that can happen in an error case: either the exception describing the error will be thrown, or a null will be returned. You must deal with both possibilities -- the former will happen the first time createView() is called for a class of a particular name, the latter every time there-after for that class name.

createView

 public final View createView (String name,                  String prefix,                  AttributeSet attrs)

Low-level function for instantiating a view by name. This attempts to instantiate a view class of the given name found in this LayoutInflater's ClassLoader. To use an explicit Context in the View constructor, use createView(android.content.Context, java.lang.String, java.lang.String, android.util.AttributeSet) instead.

from

 public static LayoutInflater from (Context context)

Obtains the LayoutInflater from the given context.

getContext

 public Context getContext ()

Return the context we are running in, for access to resources, class loader, etc.

getFactory

 public final LayoutInflater.Factory getFactory ()

Return the current Factory (or null). This is called on each element name. If the factory returns a View, add that to the hierarchy. If it returns null, proceed to call onCreateView(name).

getFactory2

 public final LayoutInflater.Factory2 getFactory2 ()

Return the current Factory2. Returns null if no factory is set or the set factory does not implement the Factory2 interface. This is called on each element name. If the factory returns a View, add that to the hierarchy. If it returns null, proceed to call onCreateView(name).

getFilter

 public LayoutInflater.Filter getFilter ()

inflate

 public View inflate (int resource,                  ViewGroup root)

Inflate a new view hierarchy from the specified xml resource. Throws InflateException if there is an error.

inflate

 public View inflate (XmlPullParser parser,                  ViewGroup root)

Inflate a new view hierarchy from the specified xml node. Throws InflateException if there is an error. *

Important   For performance reasons, view inflation relies heavily on pre-processing of XML files that is done at build time. Therefore, it is not currently possible to use LayoutInflater with an XmlPullParser over a plain XML file at runtime.

inflate

 public View inflate (XmlPullParser parser,                  ViewGroup root,                  boolean attachToRoot)

Inflate a new view hierarchy from the specified XML node. Throws InflateException if there is an error.

inflate

 public View inflate (int resource,                  ViewGroup root,                  boolean attachToRoot)

Inflate a new view hierarchy from the specified xml resource. Throws InflateException if there is an error.

onCreateView

 public View onCreateView (Context viewContext,                  View parent,                  String name,                  AttributeSet attrs)

Version of onCreateView(android.view.View, java.lang.String, android.util.AttributeSet) that also takes the inflation context. The default implementation simply calls onCreateView(android.view.View, java.lang.String, android.util.AttributeSet).

setFactory

 public void setFactory (LayoutInflater.Factory factory)

Attach a custom Factory interface for creating views while using this LayoutInflater. This must not be null, and can only be set once; after setting, you can not change the factory. This is called on each element name as the xml is parsed. If the factory returns a View, that is added to the hierarchy. If it returns null, the next factory default onCreateView(Context, View, String, AttributeSet) method is called.

If you have an existing LayoutInflater and want to add your own factory to it, use cloneInContext(Context) to clone the existing instance and then you can use this function (once) on the returned new instance. This will merge your own factory with whatever factory the original instance is using.

setFactory2

 public void setFactory2 (LayoutInflater.Factory2 factory)

Like setFactory(Factory), but allows you to set a Factory2 interface.

setFilter

 public void setFilter (LayoutInflater.Filter filter)

Sets the Filter to by this LayoutInflater. If a view is attempted to be inflated which is not allowed by the Filter, the inflate(int, android.view.ViewGroup) call will throw an InflateException. This filter will replace any previous filter set on this LayoutInflater.

onCreateView

 protected View onCreateView (View parent,                  String name,                  AttributeSet attrs)

Version of onCreateView(java.lang.String, android.util.AttributeSet) that also takes the future parent of the view being constructed. The default implementation simply calls onCreateView(java.lang.String, android.util.AttributeSet).

onCreateView

 protected View onCreateView (String name,                  AttributeSet attrs)

This routine is responsible for creating the correct subclass of View given the xml element name. Override it to handle custom view objects. If you override this in your subclass be sure to call through to super.onCreateView(name) for names you do not recognize.
