Call Getlayoutinflater() in Places Not in Activity

Call getLayoutInflater() in places not in activity

You can use this outside activities - all you need is to provide a Context:

LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );

Then to retrieve your different widgets, you inflate a layout:

View view = inflater.inflate( R.layout.myNewInflatedLayout, null );
Button myButton = (Button) view.findViewById( R.id.myButton );

EDIT as of July 2014

Davide's answer on how to get the LayoutInflater is actually more correct than mine (which is still valid though).

Can't use getLayoutInflater() in Android

Change the following line,

LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );

to

LayoutInflater inflater = (LayoutInflater) getSystemService( Context.LAYOUT_INFLATER_SERVICE );

This is because, Service is a Context. Service extends ContextWrapper which extends Context. You can also use 'this' keyword in the service.

getLayoutInflater cannot resolve

Try like this

  LayoutInflater inflater= getActivity().getLayoutInflater();

or

 LayoutInflater inflater= youContext.getLayoutInflater();

because method getLayoutInflater() belong to Activity and you must get it with getActivity() method or pass context into your adapter constructor for example :

public class YourAdapter extends ArrayAdapter {

    private Context mContext;
    private ArrayList<Strings> someList;

    public YourAdapter (Context context, ArrayList<String> someList) {
        super(context, R.layout.comment_item, someList);
        **this.mContext = context;**
        this.someList = someList;

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) View rowView = convertView;
        if (rowView == null) {
            LayoutInflater inflater = **mContext**.getLayoutInflater();
            rowView = inflater.inflate(R.layout.yourItem, null);

            rowView.setTag(viewHolder);
        }

        return rowView;
    }

}

and in your Activity

YourAdapter mAdapter = new YourAdapter ( **getActivity()**,someList);

Why isn't the 'getLayoutInflater()' resolving

getLayoutInflater() can only be used directly inside components who has their own context like Acitivty , Application etc but Fragments don't have their own context

Solution:

Declare inflater outside viewHolder and initialize it inside constructor and use inflater instead of getLayoutInflater().

LayoutInflater inflater;
public CartAdapter(List<Order> listData, Context context) {
    this.listData = listData;
    this.context = context;
    inflater = LayoutInflater.from(context);
}

@Override
public CartViewHolder onCreateViewHolder(ViewGroup parent, int     viewType) {
    View itemView = inflater.inflate(R.layout.cart_layout,parent,false);
    return new CartViewHolder(itemView);
}

Now use

// remove it , redundant 
// LayoutInflater inflater2 = this.getLayoutInflater();
View vi = inflater.inflate(R.layout.content_list_drink_detail,null);

Update : you are inflating a new view vi who's TextView toppingName and toppingName will have no data in it , so it's empty

You might want to fetch data from list like listData.get(position).getQuantity()

// this below code is not needed at all
//LayoutInflater inflater2 = this.getLayoutInflater();
//View vi = inflater2.inflate(R.layout.content_list_drink_detail,     null);
//TextView toppingName =     (TextView)vi.findViewById(R.id.toppingSelected);
//TextView toppingPrice = (TextView)vi.findViewById(R.id.toppingSelectedPrice);

Null Pointer exception when trying to call getLayoutInflater

I'm not sure why the LayoutInflater is coming back null but another way to get the LayoutInflater is to simply call LayoutInflater.from(this) or, if this isn't a Context, some other Context, maybe by using the method getContext() or getApplicationContext() depending on the class you're in.

Fragment getLayoutInflater() vs. LayoutInflater.from(getContext())

Assuming you're using Fragment 1.2.3 (or Fragment 1.3.0-alpha02, which contains the same fix for a StackoverflowError when using layoutInflater in onCreateDialog()), you should always use layoutInflater. The fragment's layoutInflater is the only one that can correctly inflate <fragment> tags or its replacement, FragmentContainerView and connect those child fragments to your DialogFragment correctly.

However, if you're not using child fragments in your XML, you shouldn't see any difference between the two.
