I'm getting a null pointer exception in my custom view (which is derived from a LinearLayout ) because it can't find its child views. Here is the code: public class MyView extends LinearLayout { public MyView(Context context, AttributeSet attrs) { this(context, attrs, 0); } public MyView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } private TextView mText; @Override protected void onFinishInflate() { super.onFinishInflate(); mText = (TextView) findViewById(R.id.text); if (isInEditMode()) { mText.setText("Some example text."); } } } Here is the layout (

When inflating an element with findViewById , Android Studio always warns me that my inflated view may return null View v = inflater.inflate(R.layout.fragment_photo_gallery, container, false); and suggests I do something like surround with my statement with a null check: if (v != null) { mGridView = (GridView)v.findViewById(R.id.gridView); } Is it recommended to always do the mentioned null check before inflating an element?

I only want to get the Object itself to get its attributes and such. And maybe (but only maybe) insert it later into the shown layout. Is that possible? Regards You should change your line to: LayoutInflater.from(context).inflate(R.layout.myfile, null); You can find it in

Inside a fragment I try to inflate two layouts besides the root layout: View a, b; public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View root = inflater.inflate(R.layout.list_fragment, container, false); //.. a = inflater.inflate(R.layout.empty_list_view, container); b = inflater.inflate(R.layout.progress_list_view, container); //.. return root; } public void showB() { a.setVisibility(GONE); b.setVisibility(VISIBLE); } So I just return a single layout from the onCreateView method. However I inflate two more, a and b. However when I display b
