inflater.inflate gives nullpointer in Adapter getview method. Why?
android, java, listadapter, nullpointerexception
Solution
`private LayoutInflater inflater;` is just declared not initialized
You need to pass the context to the constructor of adapter class and then use it to initialize inflater.
new Yourcustomadapter(ActivityName.this);
// pass the context here and other params
Then
private LayoutInflater inflater;
public Yourcustomadapterr(Context context)
{
inflater = LayoutInflater.from(context);
}

Problem
In my Android app I'm building my first custom adapter. I now run into a nullpointer at the line in which I inflate the convertView. See the code below: ``` private List<String> possibilitiesList = new ArrayList<String>(); public void setPossibilitiesList(List<String> possibilitiesList) { for (String possibility : possibilitiesList) { addItem(possibility); } } public void addItem (final String item) { possibilitiesList.add(item); notifyDataSetChanged(); } private LayoutInflater inflater; @Override public View getView(final int position, View convertView, ViewGroup viewGroup) { Log.e(this, "is called here!!"); ViewHolder holder = new ViewHolder(); convertView = inflater.inflate(R.layout.list_item_posibility, viewGroup, false); holder.possibilityTitle = (TextView) convertView.findViewById(R.id.text_possibility); holder.possibilityTitle.setText(possibilitiesList.get(position)); return convertView; } ``` and in my fragment I set the possibilitiesList as follows: ``` List<String> list = Arrays.asList(getResources().getStringArray(R.array.the_possibilities)); Log.e(this, new Integer(list.size()).toString()); // outputs 8 adapter.setPossibilitiesList(list); ``` I am 100% sure that the list_item_posibility.xml exists (Android Studio also highlights is as being existing), so I'm kinda lost on why this gives a nullpointer. Does anybody know what I could be doing wrong here?
