1. The acquisition system layout manager through the system, this approach is generally used when we obtain associated operating system and applications or systems
LayoutInflater inflater=(LayoutInflater)Context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);如Activity may be omitted if the Context, if necessary in the context of a class;
View mView=inflater.inflate(Context，R.layout.XX,root);
2. Use the following manner when added to give a ViewGroup sub-layout in an Activity
View mView=getLayoutInflate.inflate(R.layout.xx,root,false);
3. By acquiring static View, which is usually used in custom controls, such as a custom dialog or toast can be used in
View mView=View.inflate(Context,R.layout.xx,false);
4, through the LayoutInflate inflate () method is implemented, the layout of a typical embodiment of the loading BaseAdapter
View view=LayoutInflater.from(Context).inflate(R.layout.xx,rootView，false);
These are the four kinds of usage Layoutinflate. Simply by speaking about the difference between bar codes or the nature of the relationship between the following four
First: In an Activity,
public Layoutinflater getLayoutInflater(){
return getWindow().getLayoutInflater();}
The Activity at the bottom or call the Window class abstract method:
public LayouInflater getLayoutInflater(Context context){
return LayoutInflate.from(Context context);
}, While the window class is how to call it? Consider the following content
Window is to get through the static way LayoutInflater
public static View inflate(Context mContext, LayoutRes res, ViewGroup root){
LayoutInflater mLayoutInflater=LayoutInflater.from(mContext);
return mLayoutInflater.inflate(res,root);
}
It is noteworthy that LayoutInflater is also an abstract class, it is ultimately the way to get the call system
public abstract LayoutInflater extends Object{
public static static LayoutInflater from(Context mContext){
LayoutInflater mLayoutInflater=(LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if(mLayoutInflater==null){
throws Exception(Exception e);
}
return mLayoutInflater;
}
}
